Transitioning To Clouds Later
The retreating high will also allow clouds to increase later on as a storm system in the Midwest pushes east. Clouds will increase this afternoon from the west. While we will remain dry through the daylight hours, precipitation chances will increase after 8 or 9 PM west of us, after 11 PM locally, and after Midnight east of the city as light rain moves into the region in advance of the storm system. Since temperatures over the Lehigh Valley, Berks County, Poconos, and perhaps Upper Bucks County will be marginal for slippery travel, winter weather advisories are out for those places for this evening into early Tuesday morning in case rain freezes on road surfaces. Some of the upper parts of Montco could be slick -- we're talking above Pottstown and towards Pennsburg -- but the best chances of rain freezing on anything will Lehigh Valley/Berks on north. Rain thankfully will be light but it doesn't take much to foul up the roads. We'll have more information as the day progresses.
