It's official, it's a heatwave! The temp earlier today got to 90 degrees, just before 11am, and at the noon hour, the temp at Bradley made it to 92 degrees. Yes it's another hot one out there so take it nice and easy in the heat. We're not expecting 90 degree readings tomorrow, due to the fact a cold front will be rolling through later today and this evening, so this will be a short-lived heatwave, lasting only 3 days. This is the second heatwave of 2017 and it's not even summer yet! The first one took place May 17-19th.
HOT, WITH THUNDERSTORMS TODAY
While today is another hot and humid day, changes will be taking place. A cold front is expected to sag southward from Canada, which will bring more clouds into CT with the chance of showers and thunderstorms by later this afternoon. This timing is allowing readings inland to reach into the low-90s again.
With the front butting up against steamy air, we will keep an eye on the strength of the storms. While the Storm Prediction Center has placed us in the “Marginal Risk” category for severe weather today, it appears that the atmosphere will be lacking strong wind energy aloft. Without this energy providing shear, organized thunderstorms would have a harder time forming, meaning we do not expect widespread strong or severe thunderstorms this afternoon. With that said, some storms could contain torrential downpours and gusty winds and maybe even some small hail.
While it will be hot today, records are not likely to be broken. The record high on June 13the at Bradley Airport is 96F (1984) and at Sikorsky Airport is 93F (1961).
PLEASANT WEDNESDAY & THURSDAY
The front will bring relief from the heat and humidity for Connecticut. Highs will reach into the low-80s in the valley locations and at the Shoreline and remain in the upper-70s at higher elevations. Dew points will drop into the upper 40s and lower 50s, making it feel very pleasant outside. There will be a busy north to northwesterly breeze with a partly to mostly sunny sky. Though tomorrow’s highs will be cooler, they will still be above normal for mid-June. The normal high at Bradley Airport for June 14the is 79 degrees.
Thursday will be another comfortable, dry day thanks to high pressure overhead. Highs will be in the upper-70s across most of the state during the afternoon. Lows Thursday morning will be in the very refreshing lower 50s.
UNSETTLED FRIDAY & NEXT WEEKEND.
Unsettled weather will return, beginning Friday. A storm system over the Great Lakes will be nudging closer and will send a warm front towards us Friday. Most of the day will be rain-free, as the moisture field will expand during the course of the day. With that said, a few spotty showers may develop during the late afternoon, especially across western parts of the state. The clouds and onshore flow ahead of the front will hold afternoon highs down, with highs in the low and mid-70s, and hold readings up at night, with lows in the 60s.
Showers or periods of rain are possible Saturday as the aforementioned warm front will try to move through the state. It will be an active front, providing the necessary lift for this wet weather. Easterly and southeasterly winds will continue to keep temperatures tamped down a bit, with highs in the lower and middle 70s.
Showers and thunderstorms are possible Sunday, some of which may be strong. While the warm front will have cleared the state by Sunday, the cold front portion of the weekend storm will be approaching. This front will be collecting moisture along itself. Sunshine may break out for several hours during the later morning and early afternoon as a ribbon of dry air precedes the front. If we get this sunshine, it will allow surface temperatures to rise into the lower and middle-80s, which would destabilizing the atmosphere. These events, in turn, might set the stage for stronger thunderstorms Sunday afternoon and Sunday night. Keep in mind it’s early in the forecast cycle.
The cold front will likely pass through Connecticut late Sunday night or very early Monday morning. Thus, any remaining showers or thunderstorms will come to an end early on Monday and skies will clear out. The cooler air will lag behind the front, though, allowing high temperatures Monday afternoon to reach well into the 80s.
