Forecast Update
Posted Saturday 12/07/24 @ 9:38 PM — The weather for the Eagles game on Sunday will be sunny (some occasional thin high cirrus clouds at times.) Unfortunately, the departing clipper system will result in a pressure gradient that results in somewhat windy conditions, with gusts as high as 28 mph, somewhat diminishing later in the afternoon.
High temperatures will be 54º-55º near the stadium and 52ª-53º Blue Bell.
A warm front is still expected to bring light rain and drizzle on Monday, dry but cloudy for much of Tuesday, then heavy rain (1.5+ inches) Tuesday night into Wednesday before a strong cold front moves through with high winds Wednesday afternoon. Maybe some snow flurries Wednesday night.

An clipper type low pressure system moving well north of us will bring some clouds later Saturday as a southwesterly flow develops and moisture moves aloft as a pseudo warm front. That moves away on Sunday allowing skies to clear. The departing clipper will cause it to be windy on Sunday.
A southwesterly flow of milder air will be with us for Monday through Wednesday.
With the milder air, moisture and rain will move in on Monday. Some interesting weather developing Monday through Thursday ahead of another deep dip in the jet stream. Low pressure systems are expected to move up from the southwest ahead of front giving us clouds and rain.
