Mike Linden's Forecast | Winter begins and wastes no time getting going
Winter is OFFICIALLY here and Mother Nature isn't wasting ANY time getting right to the season at hand!
Daytime highs took another step back into the mid to low 30s under otherwise pretty skies across NEPA but the cold air won't stick around for long. Into the evening hours, the mild air from the south will begin to push into Pennsylvania and this will force temperatures back into the upper 40s...but will also bring plenty of moisture too. Due to the timing of the wet weather pushing in overnight and into Friday morning, a good chunk of NEPA is under a Winter Weather Advisory until Friday afternoon. The biggest threat here will be the wintry mix of rain, sleet and possibly freezing rain.
We'll first see the ugly mix starting to pick up around 5:00-7:00 Friday morning with the rain taking over around the 9:00 hour. If you're heading to work during this time or getting an early start on any holiday travel, it certainly couldn't hurt to leave a couple of minutes early just in case. Also, be careful near any bridges or overpasses as these are the most likely spots to find black ice. PLEASE drive carefully considering the extra traffic you're bound to run into the next couple of days.
The rest of Friday doesn't look too pretty under near overcast skies but at least temperatures will run warmer than normal in the mid to high 40s, low 50s. The mild air will remain in place over NEPA heading into Saturday but so will the wet weather; expect another ugly day to kick off the weekend.
Saturday evening is where Winter begins to really ramp up.
Cold air from the west is slowly plodding eastward and we should begin to feel it into Saturday evening as temperatures slip back to the low 30s. With any moisture leftover from the previous days' rain, we'll likely see the development of some snow showers along the Northern Tier and over Western PA into Sunday afternoon/evening. The lower valleys and the Poconos could get in on a potential inch or so of snowfall when all is said and done; a good chance for a White Christmas!
As for any active weather on Christmas...I'm still kind of split. While I DO think there should be an inch or so of snow on the ground for the holiday, any additional snow seems somewhat to close to call at this point. It's either another 1-2" or nothing at all.
