CHESTER COUNTY, PA — Thanksgiving is just around the corner, and many residents of Chester County are wondering what the forecast holds. Fortunately, we have a good idea of what to expect. A cold front passed through the area early this morning, but high pressure will build in behind it and persist through Thanksgiving Day. However, low pressure is expected to approach from the west on Friday and pass through our region on its way to eastern Canada. So what does this mean for Thanksgiving? Read on to find out!
Monday and Tuesday’s Weather to be Mainly Quiet
There’s not much to report weather-wise for Monday and Tuesday. A clipper system will move quickly eastward well to our north, pushing a warm front through to our north and bringing us breezy SW winds under mainly sunny skies. This will help it warm up compared to Sunday but highs will still only be mainly in the 40s. The low pressure system continues racing off into the Canadian Maritimes Monday night through Tuesday with high pressure building in over the mid-Atlantic and northeast. So overall, we can expect the weather to be quiet with little change from Monday to Tuesday.
A clipper system will move quickly eastward well to our north on Monday, pushing a warm front through to our north and bringing us breezy SW winds under mainly sunny skies. This front will help temperatures moderate compared to Sunday, with highs only reaching into the 40s. However, it will still be a mostly sunny day so get outside and enjoy it while you can!
The low pressure system that has been affecting our weather continues racing off into the Canadian Maritimes on Monday night into Tuesday. This system will push high pressure into the mid-Atlantic and northeast US, resulting in clear skies and lighter winds for Tuesday. Temperatures will be a few degrees warmer than on Monday, so highs will likely reach into the low 50s.
Tuesday Night’s Weather
Little change is expected for Tuesday night as high pressure continues to influence our weather. Skies will remain clear and light winds are forecasted, with lows dipping into the 20s to low 30s overnight.
Overall, this next period of weather looks to be relatively quiet. A clipper system will move in from the north on Monday, resulting in breezy conditions and sunny skies but temperatures only reaching the 40s. On Tuesday, this system continues moving eastward into Canada as high pressure builds over the northeast US. This will result in clear skies and warmer temperatures, with highs likely reaching into the low 50s. So although it won’t be beach weather anytime soon, at least we can expect some small relief from all the cold!
Weather for Thanksgiving and the Weekend Ahead
We’re in for some shifts in the weather patterns in the second half of the week. Here’s what you can expect…
On Wednesday, an upper level trough will begin to move into the Central US. This will cause a brief ridge to build overhead, resulting in mostly sunny skies and highs in the lower to mid 50s. Perfect weather for getting out and about to do some early holiday shopping!
By Thursday, the upper level trough will have moved eastward, allowing surface high pressure to build back in. This will keep Thanksgiving dry, though there may be some clouds around during the afternoon.
Later in the week, we’re tracking a system that could bring rain—potentially heavy rain—to Chester County on Friday. So if you’re doing any Black Friday shopping, you’ll want to make sure you have your rain gear handy! High temperatures on Friday will be in the low 50s.
The system will move out of the area by Saturday, leaving behind drier but blustery conditions. Temperatures on Saturday will only reach the upper 40s. Bundle up!
That’s all for now! Be sure to check back for updates on the forecast as we get closer to the weekend. In the meantime, enjoy this brief respite of seasonably warm weather!
