SYNOPSIS
High pressure will shift offshore Friday as a warm front lifts northward Friday night. A southerly or return flow will then set up across the east coast, before a cold front tracks through the area Saturday night and Sunday. This cold front will stall to our south on Sunday night and quickly move back northward, as a warm front, on Monday. A cold front will follow on Monday night. High pressure will then return on Tuesday and Wednesday, before weakening on Thursday.
NEAR TERM /THROUGH TONIGHT/
High pressure will be centered off the Mid-Atlantic and Southeast coasts. Low pressure over the Upper Midwest and Great Lakes will approach from the west. A warm front out ahead of that low will lift north through the region this evening, and then the cold front continues to approach behind it.
Mostly sunny skies on tap for today. The pressure gradient will tighten later today between the offshore high and low pressure moving through the Great Lakes and central Canada. South winds will increase to 15 to 20 mph with 25 to 30 mph gusts. Warm air advection will be underway, and highs today will be in the upper 60s to low 70s, except in the low 60s in the higher elevations of the southern Poconos, and in the upper 50s to low 60s along the coasts.
Winds diminish after sunset and will generally range from 10 to 15 mph. High clouds will spread in from the west. Lows tonight will be fairly warm, generally in the low to mid 50s for most of the region, and in the mid to upper 50s in Delmarva.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
After the warm front moves northward Friday night, we are well into the warm sector on Saturday as temperatures reach into the low 80s for most. Winds will also be breezy on Saturday out of the southwest with gusts at times reaching 25-30 mph. These winds do diminish into Saturday night. A cold front moves through overnight Saturday and not too much activity is expected with this front.
It will lack a lot of moisture and a passing shower looks to be the extent of any precip. The potential for a passing shower is mainly for the Poconos, parts of the Lehigh Valley, and NW New Jersey. Lows Saturday night are mainly in the 50s.
A high pressure system briefly builds in from the north on Sunday and that cold front that moves through Saturday night stalls to the south of the area. We are 10-15 degrees cooler on Sunday compared to Saturday with highs reaching the mid 60s to low 70s and it does look to be a dry day.
LONG TERM /MONDAY THROUGH THURSDAY/
A low pressure system approaches from the west on Monday which drags a warm front northward during the day. The passage of this warm front looks to lack a lot of moisture and mainly just adds in more clouds. The cold front that follows leads to some rain showers Monday evening into Monday night. There is the chance for an isolated thunderstorm during this timeframe as well.
A high pressure system then builds in for midweek. We also start to experience a stretch of mainly 70 degree highs for many Tuesday through Thursday. Another cold front looks to move in from the west on Thursday night which would lead to another potential for some rain showers.
