Good Tuesday evening!
*** A FLASH FLOOD WATCH remains in effect for all of Connecticut tonight. A SEVERE THUNDERSTORM WATCH is in effect for Fairfield and New Haven Counties until 9:00 pm ***
It's an Early Warning Weather Day as there is a still potential for more nasty weather through tonight. Showers and thunderstorms will produce very heavy downpours since the atmosphere is loaded with tropical moisture. Dew point readings reached the low to mid 70s today, which is oppressive humidity. Like we saw yesterday, flash flooding is quite possible with some locations receiving 1-2" of rain over a short period of time. If you see a flooded roadway, turn around. Do not attempt to travel through a flooded road! There is also a slight chance for a severe thunderstorm with damaging winds. Plus, lightning is always a big danger. To be safe, if you hear thunder tonight, go indoors immediately.
The threat for flooding will remain with us well into tomorrow as we expect more rain. A cold front will push through this moisture laded air tomorrow with more downpours and possible rumbles of thunder. However, the rain should end during the mid to late evening hours as the cold front finally pushes off to the east of Connecticut. We might even see some clearing before the sun goes down and humidity levels will begin to drop off.
In the wake of the cold front, the air will continue to dry out tomorrow night. That will set us up for a nice end to the workweek. High pressure will provide plenty of sunshine both Thursday and Friday. It'll be seasonably warm both days, but humidity levels will be low. Daytime highs will be in the low and mid-80s. The mercury will likely dip into the 50s and lower 60s at night, which is so much better for sleeping!
The risk of a pop-up afternoon shower or thunderstorm now looks to be fairly low this weekend! Instead, skies should be at least partly sunny both Saturday and Sunday. Temperatures will rise higher through the 80s each day, but the humidity should remain at tolerable levels.
Early next week looks warm and humid with the mercury possibly approaching 90 degrees by Tuesday afternoon. There is a chance for isolated or scattered thunderstorms Monday afternoon and Tuesday afternoon.
Have a great week and be safe out there this evening!
