Significant Weather Weekly Outlook
Once again hazardous weather does not appear likely this week in southern New England.
The most notable weather feature this week looks to be a deep upper trough that closes off over or near New England during the second half of the workweek with a stalled or very slow-moving surface low pressure system over/near eastern MA. Periods of rain appear likely Wednesday night through Thursday and possibly into Friday. The rain could help to at least put a dent in a precipitation deficit in place across most of southern New England. One significant caveat, however, is that we have experienced a number of systems over the past several weeks that have produced less rain than anticipated when several days out.
Next weekend looks to be drier and warmer. However, confidence is not all that high given that upper-level energy embedded in the global circulation is often not well resolved in a week’s time frame.
