Tornado Watch #525

A Tornado Watch has been issued for Northwestern Connecticut until 9PM.

There may be more area covered by an updated watch as the afternoon passes.

Clouds are breaking up and sun is starting to heat the atmosphere for most of Western Connecticut. CAPE values should increase quickly in response to heating. Winds at 850mb-700mb will increase through the evening and this will enhance the severe risk. I have noticed an increased threat for severe weather south of the actual watch. All residents in Connecticut should remain alert for changing weather through midnight tonight.

Here's the bulletin from the Storm Prediction Center:
