6/19/2016 - Sunday
A couple of days early around 90, then cooling off some after a front passes through on Tuesday. Need rain again, lawns starting to show it. Hardly more than an inch so far in June at HIA, about half of average. Not much likely this week, maybe Tuesday and maybe Thursday.
Looking at June-
It starts out at 77 degrees for the average high, and rises 7 degrees to 84 degrees by the end of the month. The average low starts at 57, and rises 7 degrees to 64 by the end of the month. Hard to believe that back to the warmest month of the year next month already, seems winter just quit.
The record high is 100, 3 times, the latest in 1966. The record low is 40 degrees back in 1980.
The average precipitation is 3.99".
The wettest June was 18.5" in 1972, Hurricane Agnes.
Looking back at May -
May temperatures were basically normal. The average of the highs and lows were 0.2 degrees below normal. The average high was 70.8, the average low was 53.1 degrees.
The highest temperature was 91 on the 28th, the lowest was 43 degrees on the 16th. There were 3 days making 90 degrees or above.
Heating degree days were 173, 25 above average. Total is now 4,456, 795 less than average for the season.
Cooling degree days are back, at 85, 27 above normal. Odd that both HDD's and CDD's are above normal, but a month of unusual cold and heat.
Rain was slightly below normal, at 3.46", 0.33" below normal. The greatest amount was 0.83" on the 21st.
A cloudy month, with no clear clear days! There were 15 cloudy days.
