The sky will remain mostly cloudy Tuesday with a few showers as a front stalls south of Connecticut. Although tomorrow will not be a washout, you will need an umbrella from time to time. Check out our in house model. This is an image of forecast rainfall by tomorrow night. Not too impressive. But notice the shoreline does get more than inland areas.
Heavier rain will move in late Tuesday night into Wednesday from a developing coastal storm. The soaking rain and gusty winds will be over by Wednesday morning with just a few lingering showers during the afternoon. This is another look at the RPM model (our in house model) with total rainfall totals by Wednesday night, including whatever we get Tuesday. Some models are forecasting over an inch or more of rain Tuesday night-Wednesday with southeastern CT falling in the bullseye with a coastal front or inverted surface trough enhancing rainfall. I swear I don't hate Groton. You guys are just "lucky".
I’m not convinced we get THAT much rain. The GFS model shows only half an inch of rain total for Tuesday and Wednesday with the storm moving out much faster. But at this point, it’s the outlier (meaning that most other models disagree). We’ll have a better idea tomorrow. But a soaking rain is certainly possible!
The weather improves on Thursday with plenty of sun and milder temperatures. Friday will be dry but cooler.
