Warming continues next few days… 

A progressive warming trend is expected over the remainder of the week, while remaining dry. Partly to mostly cloudy skies Wednesday as the former nor’easter’s cloud plume will still be affecting the area. Highs will reach the upper 70s Wednesday afternoon.

Any morning clouds Thursday will give way to partly cloudy skies and temperatures reaching the lower 80s. Partly sunny skies follow Friday with low to mid 80s likely ahead of the next cold front. This front may bring a few evening showers, then cooler temperatures settle in for the weekend. At least one model (GFS) shows the front stalling or getting hung up over or near the region Saturday, and low pressure moving along the boundary and bringing periods of rain later Saturday night and continuing for the majority of Sunday. Other models like the European keeps the front progressive. We will monitor details throughout the week. Returning to a mix of sun and clouds Monday, the below average temperatures Tuesday and mostly sunny.
