High pressure will be the dominant influence on the weather pattern through the end of the week. The weekend, not so much.
High pressure will produce tranquil weather conditions and seasonable temperatures today on through Saturday. Scattered clouds can be expected with winds light and variable through the forecast period. Low temperatures will range from the upper 20's to lower 30's over the interior and mid to upper 30's along the coast. High temperatures will range from the lower to mid 40's over the interior and mid to upper 40's along the coast through the forecast period.
An area of low pressure will track towards the Ohio River Valley on Saturday and then begin to redevelop along the New Jersey coast on Sunday. Periods of rain can be expected Sunday afternoon on through Monday morning as the low pressure system tracks towards the New England coastal waters. There is a threat for some freezing rain, sleet, and even snow over portions of northeastern Pennsylvania, northwestern New Jersey, the Hudson Valley, and Connecticut Sunday night into Monday morning.
High pressure return to the region on Tuesday with clearing skies and cooler conditions. Temperatures will fall back to the upper 20's to mid 30's for lows and lower to mid 40's for highs.
