AUGUST 2016 MONTHLY SUMMARY
GAITHERSBURG 2 WNW MARYLAND
by Kevin Shaw, observer in charge

Once again this month of August was warmer than normal, and
also drier than normal. There were several daily records set, mostly with maximum low temperatures with many very warm,
muggy overnights. I had the warmest August mean temperature
(78.5°) and the warmest average minimum temperature (69.2°)
ever. The maximum average temperature (87.8°) only came in as the sixth warmest ever. The 9 days with maximum temperatures of 90 or greater was actually just about normal. 6 days with measurable precipitation was predictably below the normal of about 9 days. The wettest day of the month of 1.51″ on the 17th failed to break a daily record, but the 1.31″ that fell on the 15th did break a daily record, the only such record in this dry month. An all-time record high dew point temperature of 82 was set on the 12th (records on this variable only go back through 2013 unfortunately). The highest temperature of the month of 97°
was reached on the 13th and 14th. Only the reading on the 13th went into the record book as a tied daily max temp value with the reading recorded back in 2002. Numerous daily record high
minimum temperatures were either set or tied, including 5 days in a row during our hottest temperatures of the month between the 10th and 14th, and also on the 6th, 17th and 26th.

The average maximum temperature for the month was 87.8°
(+2.9°), the average minimum temperature was 69.2° (+ 5.1°). The resultant mean average temperature for the month was
78.5° (+ 4.0°).

The month’s total precipitation amount of 2.97″ was 0.70″
below the normal August amount of 3.67″. My current year to date precipitation total of 31.23″ through August 31 is 1.28″ above the normal amount of 29.95″. All measurable amounts of precipitation fell between the 12th and 21st. Trace amounts also fell on the 8th and 9th. 6 days of measurable rain at my station was below the long-term normal amount of 8.9 days.

The month’s highest barometric pressure reading of 30.37″ on the 23rd occurred on the day with our lowest monthly minimum air (60°) and dew point (57°) temperatures of the month. The modest lowest pressure reading of the month of 29.76″ on the 6th occured during a bit of a cloudy period (but without rain) from the 5th to the 9th.

The distribution of 10 sunny, 17 partly cloudy and only 4 cloudy days fit in with the dry conditions found during most of the month, particularly at the beginning and end of the month. With plenty of muggy dew points around, there was plenty of fuel around for cloud formation; they just didn’t develop into many full overcasts at all.

There were 419 cooling degree days (CDD) and 0 heating degree days. I didn’t observe any fog in August, but with the dew points frequently as high as they were, I probably missed early morning fog occurrences when I was sleeping. There were essentially a normal amount (4) of thunderstorm days, all occurring during our wettest period of the month between the 14th and 17th. The peak wind gust during the month was a very modest 18 MPH out of the WSW on the 14th during evening light thunderstorm activity that mostly missed the station. It was a generally calm month as only 19 days recorded a PWG of 10 MPH or more. The dominant daily wind direction was 16 days with a W/SW/WSW component, followed by 11 days with an
easterly component and 4 days with a northerly component.

My maximum temperature frequencies included 9 days at or above 90°, 21 days between 80° and 89° (including 11 days with max temps of either 88° or 89°), and 1 day with 79°. On the minimum temperature frequency side of things, there were 16 days between 60° and 69° and 15 days with minimum temperatures of 70° or greater.

The diurnal range average was below normal (18.6° vs the normal of
20.8°). The max daily range of 25.2° occurred on the 7th at the end of the beginning of the month dry period (with a dew point of 58° recorded that day – 89°-64°). There were an additional 10 days with daily ranges at or above 20°, The lowest daily temperature range of 11.3° (80°-69°)
occurred on a non-descript partly cloudy August 3rd day. There were only a total of 6 days during August with daily temperature readings less than 15°.

Late July finished up relatively cool with a long 90°+ streak broken that continued into August 2016 with the first 9 days failing to reach 90° but then on August 10 we started a streak of 8 straight days of 90° or more, along with dew point temperatures well up into the 70s and even low 80s. This was probably the most oppressive period of August, if not the entire summer. Only the thunderstorms from the 14th-17th provided any sort of relief. The rest of the month finished moderately hot and muggy, but without needed rain. The tropics appear to be getting active finally as we head into September, and perhaps will be transporting needed moisture into our area in September. We shall see. Check back later to see how September works out. Please continue to watch the tropics closely for the next several weeks.

JULY 2016 MONTHLY SUMMARY
GAITHERSBURG 2 WNW MARYLAND
by Kevin Shaw, observer in charge

July 2016 featured plenty of heat and humidity, along with an abundance of precipitation with a late month rally of heavy
rainfall from numerous thunderstorms and downpours.
Numerous records were set of many types. Two record high
temperatures were recorded on the 14th (96°) and the hottest day of the month on the 25th (98°). 17 days with maximum
temperatures of 90° or greater was considerably above the
normal amount of 10 days, but not a record (22 days in July
1999). 18 days with minimum temperatures of 70° or greater
was well above normal I am sure, though I don’t keep track
of that statistic in the long term. A cool wet July 4th helped set a record low max for the date (71°). There were 6 days
with record high mins set. Rainfall was running below normal through the 27th, but then a late month rally between the 28th and 31st when 3.05″ of rain fell brought the month to 5.88″, fifth wettest all-time, and over 2 inches above normal. Daily precipitation records were set on my birthday, the 29th
(0.93″) and the wettest day of the month on the 30th (1.51″). On that day record rains fell nearby in the Ellicott City MD area with incredible devastating floods of epic proportions. NOAA declared it a 1 in a 1000 year rainfall event.

The average maximum temperature for the month was 88.8°
(+2.0°), the average minimum temperature was 69.8° (+ 4.1°). The resultant mean average temperature for the month was
79.3° (+ 3.1°).

The month’s total precipitation amount of 5.88″ was 2.14″
above the normal July amount of 3.74″. My current year to
date precipitation total of 28.26″ through July 31 is 1.98″
above the normal amount of 26.28″. Precipitation was a bit
scarce the first 27 days of the month, with 7 day (July 9-15) and 8 day (July 20-27) dry streak periods and a total of
only 2.83″ rain falling. But the previously mentioned end of month wet period of 3.05″ between July 28 and July 31 put
us above normal for the month. 11 days of measurable rain at my station was essentially normal (long term average of 10.7)

The month’s modest highest barometric pressure reading of 30.25″ on the 20th occurred at the start of our longest dry streak of the month and our hottest temperatures of the month during that streak. The equally modest lowest pressure reading of the month of 29.79″ on the 8th occurred during a generally lower pressure time of July, started around the wet 4th of July.

The distribution of 4 sunny, 17 partly cloudy and 10 cloudy days fit in with the muggy, wet conditions commonly found during much of the month. There was definitely a good deal of clouds around most of the month with the rather low amount of sunny days.

There were 443 cooling degree days (CDD) and 0 heating degree days. There were a below normal amount of 5 days with fog and a bit above normal amount (7) of thunderstorm days. The peak wind gust during the month was a modest 24 MPH out of the ENE on the 19th, during a mid-evening thunderstorm. It was a generally calm month as this day was the only day of the month with a PWG over 20 MPH. There were a large amount of days (17) during the month with a daily PWG of under 10 MPH. The dominant daily wind direction was 22 days with a SW/WSW component, followed by a much lower 8 days with an easterly component and 1 day with a northerly component.

My maximum temperature frequencies included 17 days at or above 90°, 11 days between 80° and 89°, and 3 days between 70° and 79°. On the minimum temperature frequency side of things, there were 13 days between 60° and 69° and 18 days with minimum temperatures of 70° or greater.

The diurnal range average was a bit below normal (19.1° vs the normal of
21.1°). The max daily range of 28.3° occurred on the 20th at the beginning of our longest hot spell of the month (90° – 62°) on our hottest day of the month (94°- 60°). There were an additional 14 days with daily ranges at or above 20°, The lowest daily temperature range of only 5.7° (71°-65°) occurred on July 4th when we had our 2nd highest daily rainfall amount during the month. There was only 1 additional day during July with daily temperature readings less than 10°.

July 2016 started out relatively cool and wet, but that general pattern changed around the 9th and we were mostly dry and hot through the 27th. Hopefully this pattern will break down during August and we will have a more moderate rest of the summer. The wet period at the end of July initially broke our consecutive days of 90° max temperatures and has followed us into early August so far. We shall see. Check back in a few weeks to see how August finishes out. Don’t forget we are now in Hurricane Season! We just had a lull through most of July but Hurricane
Earl has brought us a hurricane in early August, and the tropical Atlantic has started to get active once again. So pay close attention to the tropics and beware!
