FEBRUARY 2018 MONTHLY SUMMARY ROCKVILLE 2.8 WNW MARYLAND FOR THE NJWO BLOG

FEBRUARY 2018 MONTHLY SUMMARY ROCKVILLE 2.8 WNW MARYLAND
By Kevin Shaw, Observer in Charge

February 2018 was one of the warmest Februarys ever among the 3 local major
airports with long records and official normals. The warmest period was on the
20th and 21st for maxima and on the 21st for minima and broke long standing
records at these airports. My 76° and 78° on those two consecutive days and
my 61° min on the 21st fit right in with the corresponding data from the major
airports at BWi, DCA and IAD. The first 10 days of the month was generally
the coldest period of the month, but still did not hold a 32 or lower max temp
all month. Rainfall was significantly above normal at these three airports, and
snowfall was well below normal, with only one day of snow on the 17th, curiously
also the max day for snow in January, though it was even a lesser amount (0.7”).
There were 16 days with measurable precipitation, assuredly what should be
significantly above average, topped off by the 1.13″ that occurred on the 4th.
The highest barometric pressure reading of the month (30.83″) on the 13th was
actually the highest I have had at my new station, surpassing the previous highest
pressure reading of 30.80” set back on January 9, 2017. The lowest barometric
pressure reading of the month (29.64″) occurred just three days later in the very
early morning hours of the 16th , just prior to our only snowfall of the month the
next day on the 17th.. The month was quite cloudy to go along with the bountiful
and frequent precipitation, with only 3 clear days logged along with 11 partly cloudy
and 14 cloudy days. The relatively cold period the first third of the month was
overwhelmed by the later in the month general warmth.at the three first-order
stations at the 3 major DC area airport locations to make it the warm month that
it was, near records at these official first-order locations. .

There were 618 heating degree days (HDD) and 5 cooling degree days (CDD) during
the month. There were many foggy days, 13 to be exact, only 1 day with snow, and
5 windy days. That is a subjective category with no real data values to back it, just
based on my email daily weather posts that are also posted on weathertogether.net.
There was 1 day with sleet and 3 days with glaze (both occurred on the 17th mixed
in with our only snowfall during the month with light amounts of glaze on the 4th and
7th ).

Daily max/min temperatures varied widely throughout the month. My maximum
temperature frequencies included 3 days over 70°, 5 days between 60° and 69°,
6 days between 50° and 59°, 7 days between 40° and 49°, and 7 days between
30° and 39°.. On the minimum temperature frequency side of things, 2 days
between 10° and 19°, 4 days between 20° and 29°, 14 days between 30° and
39°, 7 days between 40° and 49°, and 1 day above 60°. The coldest daily max
temperature was 32.8° on the 8th and warmest daily min temp was 61.2° on that
warmest day on the 21st.

The diurnal range daily monthly average was 15.5°. Our greatest daily range of
temperature was 30.6°, formed from a high of 67.1° and low of 36.5° during the
first of 2 mini-2 day “heat waves” during the month. This was the only day with a
range over 30°, We had an additional 8 days with daily ranges above 20°. Our
lowest range of temperature was 3.5° on our wettest (1.13”) day of the month
(13th) when our readings (34.6° and 31.1°) teetered precariously around the
freezing mark, mostly just above, to give us mostly all rain and just a bit of glaze.
There were a total of 8 days with diurnal temperature ranges less than 10.0°, an
increase of 2 over last month. The distribution of these low and high diurnal range
days was spread out fairly uniformly during the month.

With yet another month to study the most recent instrument changes made in mid-
August, data appears to be stable and an overall data quality improvement success.
I am still constantly checking on my data quality frequently along with some of my
Maryland weather cohorts. I have been swapping out gauges when frozen precipitation
occurs to allow for casual, comfortable melting inside my apartment. Unfortunately the
“snow stake” was pulled out early in February when high winds knocked it over partially
at a significant angle and has not been placed back outside through the current time.
I did get a new hand-held anemometer that is especially sensitive to light winds, a good
thing as that is a persistent trait at my relatively calm location. I also have continued
just about daily GLOBE Cloud observations, complete with submission of sky pictures at
the time of the observation, usually timed with the passage of satellites and also solar
noon right now with the time change about 70 minutes past actual EDT noon. Please ask
me any questions you want at any time about my station setup and/or my data through
any means available to you.

January 2018 Weather summary statistics and summary description for NJWO Blog

JANUARY 2018 MONTHLY SUMMARY ROCKVILLE 2.8 WNW MARYLAND
By Kevin Shaw, Observer in Charge

January 2018 started my second year at my apartment observing the weather and
living at this location in West Rockville MD. The month started off with a bang, as
I had my coldest week ever (1st-7th) and coldest days, with the first days of
maximums in the teens on the 5th and 6th and my coldest min ever of 2.9° on the
morning of the 7th. Combined with the last 5 days of 2017, the 12 day period from
December 27th-January 7th is easily the longest sub-freezing max temperature period
in my short period of record. But even with much longer duration official stations in the
area, this snap was quite epic and near the all-time record long period of cold. The rest
of the month was generally much warmer, with only a few seasonably cold days and many
days with highs in the 50s and 60s (66.5° max on the 12th was the highest). Rainfall
and snowfall was below normal, with only a few days of snow, all less than an inch.
There were 9 days with measurable precipitation, probably just a bit below normal,
topped off by the 0.90″ that also occurred on the 12th. The highest barometric
pressure reading of the month (30.74″) on the 26th was actually the highest since
early March, but on a seasonable day with temperatures topping off in the mid 40s.
The lowest barometric pressure reading of the month (29.37″) occurred just after
midnight on the 13th and was associated with by far our wettest two days of the
month (1.35″). The month was pretty cloudy despite the meager precipitation, with
6 clear days logged along with 15 partly cloudy and 10 cloudy days. The general
reversal of that very cold pattern at the start of the month balanced out temps
to be just a bit below normal values at the three first-order stations at the 3
major DC area airport locations.

There were 991 heating degree days (HDD) and 0 cooling degree days (CDD) during
the month. There was only 4 days with fog, 4 days with snow, and a new category,
9 windy days. That is a subjective category with no real data values to back it, just
based on my email daily weather posts that is also posted on weathertogether.net.
There was 1 day with sleet and 1 day with glaze (on the 8th as we were getting out
of the deep freeze).

Daily max/min temperatures varied widely throughout the month. My maximum
temperature frequencies included 5 days between 60° and 69°, 5 days between
50° and 59°, 6 days between 40° and 49°, 8 days between 30° and 39°, 5
days between 20° and 29°, and 2 days colder than 20°. On the minimum
temperature frequency side of things, there were 3 days lower than 10°, 11 days
between 10° and 19°, 7 days between 20° and 29°, 6 days between 30° and 39°,
3 days between 40° and 49°, and 1 day 50° or above. The coldest daily max
temperature was 16.8° on the 5th and warmest daily min temp was 56.2° on that
“busy” day on the 12th.

The diurnal range daily monthly average was 17°. Our greatest daily range of
temperature was 41.5°, formed from a high of 60° and low of 19° as a strong
cold frontal passage dropped temperatures quickly after a warm start. This was
the only day with a range over 40°, only one other day had a range over 30°
but we had an additional 8 days with daily ranges at or above 20°. Our lowest
range of temperature was 6.7° on our coldest max day of the month on the 5th,
formed from a high temperature of 17° and a low temperature of 10°. There
were a total of 6 days with diurnal temperature ranges less than 10.0°, a
decrease of 1 over last month. The distribution of these days was spread out
over the month, on both warm and cold days.

With yet another month to study the most recent instrument changes made in mid-
August, data appears to be stable and an overall data quality improvement success.
I am still constantly checking on my data quality frequently along with some of my
Maryland weather cohorts. With the paucity of snow, my recently installed
snowboards have not gotten much action this winter so far. With the recent warm
spell I have returned the inner tube and funnel to my cocorahs rain gauge setup,
as below freezing temps do not appear to be returning the rest of February into
early March. I have been swapping out gauges when frozen precipitation occurs to
allow for casual, comfortable melting inside my apartment. Unfortunately the “snow
stake” was pulled out early in February when high winds knocked it over partially at
a significant angle and has not been placed back outside through the current time.
I did get a new hand-held anemometer that is especially sensitive to light winds,
a good thing as that is a persistent trait at my relatively calm location. I also have
resumed taking daily GLOBE observations, complete with submission of sky pictures
at the time of the observation, usually timed with the passage of satellites if at
all possible. If not, I try to take the observation around the time of solar noon,
about 20 minutes past actual noon. Please ask me any questions you want at any
time about my station setup and/or my data through any means available to you.

NOVEMBER 2017 – CLIMATE SUMMARY
ROCKVILLE 2.8 WNW MARYLAND
by Kevin Shaw, observer in charge

November 2017 was significantly drier than normal with near normal temperatures,
according to the NWS PRESTO November 2017 publication. The 2.04″rain that did
fall all month was mostly concentrated in the first part of the month, as over 84%
of the month’s total precipitation fell on 4 straight days between the 4th and 7th
(1.72″). There was a total of 8 days of measurable rain. No snow fell. Temperatures
fell slowly through the month as would be expected for November, with a most notable
cold snap from the 10th – 12th that marked our first freeze of the season. It is very
unusual to have the first freeze occurring on the same date throughout the region.

A brief warm period occurred at the beginning of the month on the 2nd and 3rd,
with maximum temperatures recorded in the low 70s. Minimum temperatures
recorded in the low-mid 50s occurred on the 3rd, 5th and 6th. Our highest
barometric pressure reading of the month (30.67″) occurred on the 11th,
coincidentally on our coldest day of the month. Our lowest barometric
pressure reading of the month (29.30″) occurred on the 19th on one of
our lighter rainy days during the month. We had 6 days with freezing
minimums (probably a good bit below normal). There were 9 clear days,
13 partly cloudy days, and 8 cloudy days during the month. Not really
a month of many extremes though DCA and IAD came close to record
low temps on November 11. Whether that is any indication for the rest
of the winter remains to be seen.

There were 564 heating degree days (HDD) and 0 cooling degree days (CDD)
during the month. There were 4 days of fog during the month, but no days
with thunder as best I know of.

My maximum temperature frequencies included 2 days between 70° and 79°,
3 days between 60° and 69°, 16 days between 50° and 59°, 8 days between
40° and 49° and 1 day below 40°. On the minimum temperature frequency
side of things, there was 6 days between 20° and 29°,13 days between 30°
and 39°, 8 days between 40° and 49°, and 3 days between 50° and 59°.
The coolest daily max temp was 37.0° on the 11th and warmest daily min
temp was 53.6° on the 3rd.

The diurnal range daily monthly average was 16.8°. Our greatest daily range
of temperature was 35.2°, formed from a high of 60.3° and low of 25.1° on
a mostly sunny day on the 18th. There were 8 days total with daily ranges at
or above 20.0°.while our lowest range of temperature was 7.1° on a lightly
rainy day on the 5th, formed from a high temperature of 58.5° and a low
temperature of 51.4°. There were only a total of 3 days with minimum diurnal
temperature ranges less than 10.0°, a decrease of 2 over last month.

With yet another month to study the instrument changes made in mid-August,
data appears to be stable and an overall data quality improvement success. I
am still constantly checking on my data quality frequently along with some of
my Maryland weather cohorts. Winterizing of the gauges has mostly taken
place. Marty and I established a good location for the snowboards, and they
have already been put to use with a few light snows occurring so far in
December. I haven’t decided whether or not to move my cocorahs rain gauge
closer to the building to ease efforts for winter reading, especially during icy/
snowy periods. I have some spikes to put on my shoes that so far have worked
on a few icy street, sidewalk, and slippery snow/ice on grass occurrences when
traveling to and from my rain gauge. I now only have the outer cylinder in place
on my cocorahs gauge to minimize freezing of some of the parts of the gauge,
and to better catch snow for water equivalent purposes. Within the past week
Marty brought over a “snow stake” that we plunged into the ground near the
flagpoles so that with binoculars I can read the general snowfall accumulation
from my balcony. We shall see how that works out. I still will go out to the
snowboard as long as it is safe to take official measurements. Please ask me
any questions you want at any time about my station setup and/or my data
through any means available to you.

AUGUST 2017 – BRIEF CLIMATE SUMMARY
ROCKVILLE 2.8 WNW MARYLAND
by Kevin Shaw, observer in charge

August 2017 was a bit cooler and drier than normal. The 4.09″ of rain this month
was less than half July’s amount, but at least nothing close to being abnormally
dry. 14 days with measurable rain was a bit above average and generally spread
fairly evenly throughout the month. Many of the wetter days of the month had max
temps in the 70s, and actually the coolest day of the month on the 29th (66°) had
one of the greater precipitation amounts for the month (0.55″). Glad to report of
only 4 days of max temps of 90 or greater (rounded to the nearest degree values).
The highest temp of the month of 91.6° was not really that high, but was made more
oppressive with the max dew point temperature of August of 81° reached on that
day (18). There were a total of 3 days where dew points remained above the 70°
mark all day. Conversely there were 13 days where the dew point fell into the 50s.
My lowest temperature for the month was 59.1°on the 30th, barely dipping below
the 60° the only time during the month. After 90° was reached on the 23rd, the
remaining days of the month mostly had days with max temps in the 70s, including
the one previously mentioned (66° on the rainy 29th)

The hottest period of the month (August 16-22) was when all but one day had max
temps above 85°, including 3 of the 4 days at or above 90° during the month. This
period was also quite dry, totalling only 0.18″ of rain.

There were 2 heating degree days (HDD) and 277 cooling degree days (CDD)
during the month.

My maximum temperature frequencies included 4 days of 90° or more, 14 days
between 80° and 89°, 12 days between 70° and 79°, and 1 day below 70°. On the
minimum temperature frequency side of things, there was 2 days below 60°, 22
days between 60° and 69°, and 7 days of 70° or over.

The diurnal range daily monthly average was 15.7°. Diurnal ranges were somewhat
supressed due to the abundance of cloudiness during the month, and real lack of
cool or hot days that always help. The maximum daily range of only 22.6°occurred
on the 9th (82.7°- 60.1°). There were only 4 days total with daily ranges at or above
20.0°. The lowest daily temperature range of 5.2° (66.0°- 60.8°) which occurred on
the 29th was the 5th wettest day of the month and by far the coolest max of the month.
Just like in July, there were only a total of 3 days with minimum daily temperature
ranges less than 10.0°.

My cocorahs (official) 4 inch rain gauge was moved mid-month (on the 16th) which I
hope will provide hassle free and more accurate readings from that point forward.
Also the VP2 tipping bucket rain gauge was re-attached to the housing on the VP2
sensor suite, and though not sited perfectly, at least it gives me a good indication
that it did rain and the timing of the rain which now shows up in my weatherlink
software. Please ask me any questions you want at any time through any means
you can.

Hygrothermometer unit and radiation shield. Checks yielded
very good temperature comparisons. This temperature data
will now be included in NJWO monthly summaries and in
Cocorahs to reflect good comparative results with other
nearby stations.
