Oppressive humidity, more storms, and a heat wave in the forecas - WFSB 3 Connecticut

Technical Discussion

Oppressive humidity, more storms, and a heat wave in the forecast!

Posted: Updated:


So far, this Thursday has featured dry, hot and humid weather.  As of the Noon hour, temps were in the mid and upper 80s with heat index values in the lower 90s in many towns.  As temperatures continue to climb, today will likely become our 20th day this year 90 or higher!  Additionally, given that this afternoon could be like yesterday afternoon, with isolated storms developing that could be strong to possibly be severe, we have declared an Early Warning Weather Day.  The main threat will be a damaging wind in the stronger storms that develop, with flooding also a concern as the rain will be quite heavy.  As far as timing is concerned, storms will likely move into southwestern CT by mid-afternoon and then work into the central part of the start near the evening commute time, then continue pushing east thereafter but likely weakening as they do so. 

Tomorrow will essentially be a carbon copy of today:  hot and humid with a chance for afternoon storms.

High pressure in the Western Atlantic will continue to pump tropical air into Southern New England.  Today will be partly sunny, hot and humid.  Highs will be in the 80s to near 90 degrees.  There will also be a chance for a shower or thunderstorm, primarily in the afternoon and evening.  While our weather will be dry most of the time, some storms will produce torrential rain, and there may be a risk for some very localized flash flooding.  There is also a chance for isolated wind damage.  The best chance for showers and storms will be across Central, Northern, and Western Connecticut or basically along and to the north of I-84.  The risk will be lower to the south and east of Hartford.

The risk of showers and storms may be a little higher statewide tomorrow.  With more in the way of cloud cover, afternoon highs are expected to remain in the mid and upper 80s.  However, the humidity will remain quite high with dew points in the low and middle 70s.


A trough will move into the humid air on Saturday.  That means there will be a good chance for more showers and a few thunderstorms.   With an abundance of cloud cover, temperatures will probably stay in the 80s for highs.

High pressure will move into the Northeast on Sunday.  Therefore, it’ll be a quiet day.  We don’t expect any showers or storms.  However, it will be hot!  We are forecasting mostly sunny skies and highs 90-95.  The humidity may drop off a little.  Dew points could drop into the 60s.


The hot weather will continue Monday, Tuesday, and Wednesday.  The humidity will be higher again as well.  All 3 days should be partly sunny with highs in the low and middle 90s away from the coast.  Monday should be dry, but there will be a better chance for a shower or storm Tuesday afternoon/evening.  There may be some isolated thunderstorms on Wednesday.

If our current forecast holds true, we will have a heat wave that will last at least 4 days from Sunday through Wednesday!

JULY 2018…

The month of July is almost over!  The average temperature at Bradley International Airport will come in at or close to 76.1 degrees, which is 2.5 degrees warmer than normal.  That means this July will be the 8th warmest on record for the Greater Hartford Area, and records date back to 1905.  That is quite impressive!  We had 11 days that were 90 degrees or higher.  The hottest day was July 1st when the high temperature was 98 degrees at Bradley.  Temperatures were in the 90s the first 5 days of July, concluding a heat wave (which began in late June) that lasted a total of 7 days.

The first half of July was dry, but the second half was quite wet.  Total rainfall for the month was 6.39”, which is 2.21” above normal.
