Discussion

KEY MESSAGE 1: No significant weather concerns this week.

High pressure centered over New England will build east and then move offshore tonight. A weak cold front passes through the region Friday, and then high pressure returns for the weekend. Low pressure may approach the region for the start of next week.

With high pressure remaining north/northeast of the area today, we expect another sunny and dry day. High temps will range from the upper 50s/low 60s across the far N/W areas to the mid/upper 60s elsewhere. These temps a bit above normal for Oct. 28.

After that, dry conditions through Saturday with high temperatures generally from the mid and upper 60s on Wednesday to the mid 70s or so by Friday. Cooler, but still slightly above normal temperatures expected for this weekend. Rain may arrive on Sunday or Monday depending on the timing, strength, and placement of that aforementioned low pressure system.
