Tuesday Forecast

Good morning! While the Gulf Coast is seeing much of the action in the weather world as a result of post-tropical cyclone Marco and tropical storm Laura, we can expect some exciting weather here in New England today.

Day 1 convective outlook (NWS)

The above image is the Storm Prediction Center's (SPC) day 1 categorical outlook, showing a slight risk of severe thunderstorms for much of New England and an enhanced risk just to our south. There is a large amount of shear in the atmosphere, which could cause gusty winds today. Additionally, with a significant about of CAPE, we could see some larger hail today. As it tends to be the case with summertime convective weather, any storms that do pop up will be fairly isolated and likely short-lived. Here's what the HRRR thinks for 5 p.m. this afternoon.

HRRR for 5 p.m. (Tropical Tidbits)

Notice the "line" of storms that extends from western West Virginia and southern Ohio up into Quebec. That "line" will move southeastward throughout the afternoon as a result of a cold front and trough moving in that direction. The HRRR will refresh throughout the day, better forecasting exact locations that should see storms. So while on the above map it looks like northern Connecticut and southern Vermont/New Hampshire will see storms around around 5 p.m. that is likely to change throughout the day as the model undergoes new runs.

Be sure to keep your eye on the sky and check radar throughout the afternoon in preparation for any convective storms that pop up!
