Weekly Significant Weather Outlook
Finally, a Break in the Heat and Humidity Later this Week
Hot and humid conditions persist into the first half of this week, but a strong cold front on Thursday will bring cooler and much less humid weather to southern New England. The cooler temperatures and much less humidity (dewpoints in the 40s and lower 50s) should continue through next weekend.
Scattered late afternoon and evening thunderstorms remain a possibility Monday through Wednesday. That strong cold front may trigger some strong thunderstorms late Wednesday night or Thursday depending upon the front’s timing. Current projections have the cold front passing through our region Thursday morning when surface heating is more at a minimum. Thus, the risk of strong thunderstorms appears low unless the front’s progress should prove to be significantly slower.
The tropics have been fairly quiet so far. However, a tropical wave is expected to move off the African coast early this week and may undergo gradual development as it progresses westward through the eastern tropical Atlantic.
