April 2019 was drier and warmer than normal. My max temp (68.8°) was 3.5° above normal

and my min temp (49.7°) was even more significantly 6.8° above normal, resulting in the

mean temperature (59.3°) to be 5.2° above normal. My total precipitation of 2.36″ was

0.93” below the newly computed normal precipitation April value for my station of 3.29”.

There was no snowfall recorded, though some northern county areas did record a few

trace flakes on the morning of April 1. There were a lot of smaller amounts of daily

precipitation leading to an above normal 13 days with measurable precipitation. .

There were a few colder than normal days during the first few days of the month which

included the only day with a freezing min (30.2° on the 1st) during all of April. The rest

of the month had seasonable to seasonably warm temperatures, but nothing summerlike

as above 80° was reached only twice during the month. There were 5 days during the

month when mins of 60° or greater were reached however.

There were 13 days with measurable precipitation, highlighted by the monthly maximum

of 0.67″ on the 26th helped by a strong mid-afternoon thunderstorm accompanied by

my monthly lowest pressure reading of 29.36”. The wettest storm period of the month

was on the 25th-26th when a total of 0.71” was recorded. Precipitation was spread

fairly evenly throughout the month with only two modest 4 day streaks of no rain on

the 1st-4th and 21st-24th. The highest barometric pressure reading of the month of

30.46” occurred on the 29th. There were no really notable precipitation days during

the month as all days with measurable precipitation were well under a half an inch daily

except of course for the rainiest day on the 26th as already noted. .

The highest dew point temperature reached during the month was 68° on the 19th.

There were 11 days in April when dew point temps were 60° or higher, values I consider

humid for April. My warmest air temperature of the month (80.8°) was recorded a few

days later on the 23rd. The lowest dew point temperature value was reached on the 1st

(coldest day of the month) when a value of 15° was reached.

April had 12 cloudy days, 16 partly cloudy days, and only 2 really clear/sunny days.

There were 196 heating degree days and 23 cooling degree days during the month.

There were 5 foggy days, 2 windy days, and 3 days with thunder during April.

Daily max/min temperatures varied as they usually do during the spring. My maximum

temperature frequencies included 2 days over 80°, 14 days between 70° and 79°, 10

days between 60° and 69°, 2 days between 50° and 59°, and 2 days between 40° and

49°. On the minimum temperature frequency side of things, there were 3 days

between 30° and 39°, 11 days between 40° and 49°, 11 days between 50° and 59° and

5 days above 60°. The coldest daily max temperature was 46.3° on the 1st while the

warmest daily min temp of 64.6° was on the 19th.

The diurnal range daily monthly average was 19.1° (- 3.3°). Our greatest daily range of

temperature was 33.0° on the 3rd, formed from a high of 66.4° and the low of 33.4°.

We had a total of 5 days with daily ranges above 25.0°. Our lowest range of

temperature was 9.0° (73.6°-64.6°) on the 19th during our highest dew point and

warmest min values of the month. There were 8 total days with diurnal temperature

ranges of less than 15.0° throughout the month, spread out fairly evenly..

April 2019 was a typical transitional month from winter to spring, with patterns during

the month generally filling the bill quite well. No problems were experienced with my

weather station during the month thank goodness. I recovered all of the winter snow-
measuring devices during the month, and broke out my lightning detector.
