Humidity rises through the evening tonight with periods of much needed rain on Tuesday. That rain will come down heavy at times with embedded thunderstorms possible too. Scattered showers and thunderstorms will last through the evening commute before tapering off.
We really do need the rain. Check out the levels of rivers and streams across the state. Most are running below normal or “much below normal”.
We’re also running a 3”-4” rainfall deficit when you look at the last 30 days.
1”-2” of rain is possible for most of the state with some locally higher/lower amounts.
That’s not enough for flash flooding for a majority of the state (which as you can see from the graphic below would need to be more than 3.5” over a 3 hour period). That threshold is lower in southern Fairfield County where you will find the only Flash Flood Watch in the state right now.
That being said, flooding is still possible for poor drainage areas/low lying areas if the ground doesn't absorb incoming rain fast enough in some spots.
It turns less humid on Wednesday with the chance for a pop up afternoon shower or thunderstorm. Thursday looks awesome. The humidity drops even further with lots of sun. There is a chance for afternoon showers or thunderstorms looking ahead to Saturday.
