Technical Discussion: Wednesday could be in 80s

It may be early September, but yesterday was one of the hottest days of the summer season. The mercury peaked at 93 degrees at Bradley International, which is a tie for the 2nd hottest temperature this summer. It was also 93 degrees on July 1st. The hottest day this summer was July 2nd with a high of 95 degrees. Humidity levels were also oppressively high. Dew point readings reached the low and mid 70s. The combination of the heat and humidity sent the heat index close to 100 degrees in parts of the state!

Relief from the steamy weather arrived last night in the form of a cold front and we're already starting to feel the difference! A northwesterly breeze is ushering in drier air and dew point readings have dropped into the 50s. With that said, it'll still be quite warm for early September. Temperatures will rise well into the 80s under mostly sunny skies, but it will feel much better thanks to the lower humidity. We can also look forward to better sleeping weather tonight. With clear skies and light winds, temperatures will dip into the 50s in many outlying areas.

Tomorrow will be a lot like today…sunny, dry, and warm! By Friday, a southerly breeze will develop in advance of the next cold front. That means the heat and humidity will ramp up once again. We should see highs close to 90 degrees in parts of the state Friday afternoon and dew point readings will likely rise into the 60s. Other than the warmth, we anticipate a quiet day Friday with mostly sunny skies.

The weekend will bring a number of changes. A cold front will slowly push through the warm, humid air on Saturday. That means there will be a good chance for showers and thunderstorms. It'll still be quite warm with highs in the 80s. Showers could linger into Sunday morning as the cold front moves away to the south of Southern New England. However, drier air should bring clearing skies Sunday afternoon and the humidity will drop to more comfortable levels. Sunday will also be cooler with highs in the 70s to near 80 degrees.

Early next week will feature the kind of weather will normally expect in early September! High pressure will bring sunshine, low humidity, and comfortable temperatures. Daytime highs will be in the 70s and nighttime lows will be in the 50s with some 40s in the normally cooler locations. Nice!

Here is a look back at August and the Meteorological summer (June, July, and August):

August was cooler and slightly drier than normal. The average temperature at Bradley International came in at 70.3 degrees, which is 1.6 degrees below normal. There were only 2 days with a high temperature of at least 90 degrees. The highest temperature was 91 degrees on the 27th and the coolest temperature was 51 degrees on the 19th. 19 days had an average temperature that was below normal, 4 days were exactly normal, and only 8 days were warmer than normal! Total rainfall for the month was 3.76", which was 0.17" below normal.

For the Meteorological Summer, the average temperature was 71.4 degrees. The normal or average temperature for June, July, and August is 71.3 degrees. Very close! The average temperature in June was 69.5 degrees, which is 1.0 degree above normal. The average temperature in July was 74.5 degrees, which is 0.9 degrees above normal. As we mentioned above, August was 1.6 degrees cooler than normal. While it was a fairly typical summer when it comes to the temperature, the 3 month period was drier than normal. June rainfall was only 1.71" at Bradley International, which is 2.64" below normal. July rainfall was 4.49", which is 0.31" above normal. August rainfall was 3.76", which is 0.17" below normal. Total rainfall for the summer was 9.96", which is 2.50" below normal! It should be noted, some parts of the state had a very wet summer especially the Litchfield Hills.

Adding up all of the 90 degree days for this year so far, we are now up to 13 thanks to today's hot weather. We had 1 in May, 1 in June, 8 in July, 2 in August, and now 1 in September. The normal or average number of 90 degree days in a year is 15. The all-time record is 38 days back in 1983!
