Fire Weather Planning Forecast for Southern New England

409 PM EDT Sun Sep 13 2026
.DISCUSSION...
A few additional rounds of lighter showers early this evening
come to an end around midnight. Any lingering scattered showers
depart the southeast New England coast by mid-morning Monday.
Otherwise, dry and seasonable conditions are on tap for Monday.
Minimum RH values fall to between 45 and 50 percent except near
the coast where values will be closer to 60 percent.
.Outlook...Tuesday through Saturday...
Another dry and seasonable day on Tuesday. However, a brief bout
of summer warmth is possible Wednesday and/or Thursday ahead of a
cold front. Much of the upcoming work week will feature dry
weather. A few brief showers are possible sometime Thursday
and/or Friday...but it does not look to be significant.
