WEATHER SUMMARY:
Looking at the weather map this afternoon there isn’t too much on it of any concern. The devil, however, is always in the details. High pressure over southern Canada is pressing toward the southeast and will eventually push a backdoor cold front, now draped across central New England, to the south through Southern New England by tomorrow morning. When the backdoor front passes through it will turn winds everywhere into the NE and, hopefully also allow some slightly drier air to filter down from Canada. The east component of the wind may, however, keep Atlantic moisture and some level of low clouds in especially at the coastline during the next 48 hours or so. Temperatures will also be a challenge to forecast as where you are relative to the coast will determine just where your high temperatures will go each day. Areas close to the coast will hug the 50’s and perhaps low 60’s at times while interior New England should easily reach the mid 60’s and, especially by Wed/Thu, the low 70’s.
This cool maritime air mass will eventually be replaced by a warmer continental air mass by Friday as winds turn into the SW. I expect that 70’s to even the low 80’s will prevail across much of SNE then. That will be a treat.
Saturday and especially Sunday look to be cooler as clouds increase along with the increasing chance of a shower by Sunday.
For those of you wondering, Tropical Storm Arthur was off the NC coast this afternoon. Arthur is moving toward the NE and will continue to move in that direction through the next 24 hours. Arthur is not expected to represent a direct threat to land, but it will cause choppy 7-9′ seas along the southern New England coast as the storm passes to the south on Tuesday and Wednesday.
