Dry conditions for the weekend but a storm system will bring wintry impacts to the area early next week

Posted 9:30 AM Friday, November 27, 2020

There may be an occasional peak of sunshine now and then but clouds will again be the dominant feature of Friday’s weather. A brief period of sprinkles or drizzle will be possible at times in random spots across the area and temperatures this afternoon will generally top out a degree or two on either side of 50°.

A push of colder air will move in tonight and temperatures will cool to the mid-30s by early Saturday morning across the Valley. The colder air will stay in place for Saturday keeping a lid on afternoon highs as high pressure builds into east-central Ohio. Expect to see decreasing cloud coverage through the day as the high takes hold. Temperatures will only warm to the mid-40s.

The pick day of the weekend comes on Sunday with plenty of sunshine and temperatures warming back to the low to mid-50s.

UPDATE ON THE IMPENDING WINTER STORM
Attention then turns to the much-advertised winter storm that is expected to arrive early in the workweek. Confidence continues to increase that we will see wintry impacts from this system perhaps as early as Monday night. However, odds that this becomes a “big ticket” snowstorm for the Valley are very low.

The models are in pretty good agreement for a low pressure system to move from West Virginia into western Pennsylvania and rain will overspread east-central Ohio through much of the day Monday. Thereafter, the models begin to waver on the placement of the system which brings variations in when and where snow becomes an issue.

For now it looks like rain will transition to snow sometime Monday night as colder air wraps into the system as it travels northward into the Great Lakes. Generally speaking we don’t see big snow amounts from scenarios like this in our area.

That being said, the storm is still 4 days out and the exact path the storm system takes will be very important with regards to snow amounts. This morning’s models vary on the path and these differences can result in major changes in snowfall amounts for a given area. It’s going to be a couple of days before the forecast gets fine-tuned.

We should begin to see some early expectations of snow amounts on Sunday. Until then, most of the forecasts you encounter will be mainly speculation and wishful thinking.

As you enjoy the weekend I would keep in mind that a couple of inches of snow is certainly possible in the Valley Monday night through Tuesday. Heavier snow amounts will be likely in and around the primary and secondary snow belt counties so keep that in mind if you travel north for work or school.

AFTER THE STORM
Expect several days of colder weather behind the system next week. Temperatures Tuesday onward will generally top out in the low-40s with nighttime lows in the upper-20s. Another push of colder air will arrive next weekend.

I’ll continue to keep you posted on the evolution of our storm system for next week through the weekend. Look for updates posted here on the TuscWeather website and the TuscWeather app. I’ll also provide general info as I get more info on Twitter (@tuscwx). Have a great weekend and be safe out there.
