Technical discussion: Showers increase in coverage tonight!


Good Thursday Evening!

Despite the warm weather the last couple of days, this August is still averaging much cooler than normal. We are now 3 weeks into August and the average temperature at Bradley International is coming in at just 70.1 degrees. That is 2.7 degrees below normal! Today's highs were in the 70s to near 80 degrees, but temperatures will now trend downward again for a couple of days. However, big changes are on the way for next week. More on that coming up!

Tonight will be mild and a bit muggy. Overnight lows will range from 60 to 65 degrees. Showers will increase in coverage tonight and a few heavier downpours will mix in as well. We can't rule out a rumble of thunder in some towns. Tomorrow will be cloudy with showers and perhaps even some drizzle. Plus, a cooler east to northeasterly flow will develop as high pressure begins to build southward from Eastern Canada. Daytime highs tomorrow will range from the upper 60s in the Litchfield Hills to the low and mid 70s elsewhere.

The atmosphere will dry out over the weekend as high pressure continues to build southward across New England. That means weather conditions will improve nicely! Saturday may start out overcast, but the clouds will break up and the sky should become partly sunny by afternoon. Temperatures should reach the mid to upper 70s. We can't rule out a stray shower or two, but most of the day will be dry. Sunday will be the pick of the weekend with a mostly sunny sky, low humidity and highs ranging from 75 to 80 degrees! Plus, we'll enjoy comfortable sleeping weather this weekend with nighttime lows in the 50s to near 60 degrees.

High pressure will keep us dry through next Wednesday and possibly beyond. Plus, temperatures will be on the rise as the atmosphere aloft turns warmer from top to bottom. Temperatures will rise higher through the 80s with each passing day and we could be feeling the first 90 degree heat of the month by either Wednesday or Thursday! The highest temperature so far this month is 89 degrees and that occurred on August 5th. The last time we had a day in the 90s (90 or higher) was all the way back on July 23rd when the high was 93 degrees at Bradley International.

We are also keeping an eye on a tropical disturbance nearing the Leeward Island. This system could develop into a tropical depression or a tropical storm over the coming days as it tracks close to Puerto Rico and Hispaniola. Hopefully, the mountainous terrain will keep this disturbance from gaining too much strength. However, once it emerges over the warm water surrounding the Bahamas, it could strengthen. Right now, this system does not appear to be a threat to the United States Mainland. However, the European Model does bring the system within a few hundred miles of Nantucket next week before curving in out to sea. We will keep you updated!

Enjoy the rest of your week!
