Good Friday evening and welcome to the weekend. We are starting the weekend off with a touch of March weather. Temps are mild, winds are cranking and showers are on the move. This is all ahead of a monster change as we roll into the new year.
Some thoughts on "the change".
- Front number one arrives on Sunday with a couple of showers, gusty winds and falling temps. Highs will be in the 40s early in the day and will crash into the 30s from west to east.
- Some flurries and light snow showers will dance around Sunday night.
- The real push of arctic air arrives Monday as a strong disturbance pushes in from the northwest. This will cause widespread light snow to break out. The NAM simulated radar is just now picking up on this...
- Northwesterly winds kick in by Monday afternoon and continue into Tuesday. This will pick up moisture off the Great Lakes to enhance the upslope flow. Widespread snow showers and squalls should be the end result.
- I do expect accumulation for many areas with the potential for a nice sized snowfall for some.
- Winds will gust to 20mph or higher during this time and that means some blowing powder and very cold wind chills.
- Highs Monday and Tuesday will stay in the 20s with lows in the low to mid teens by Tuesday morning.
The European Model shows the frigid blast...
Have a great evening and take care.
Good Friday everyone. Our big holiday weekend is kicking off on a mild and windy note across the region today as our eyes turn toward a blast of winter to start 2012. This will mark a nice change from the boring stuff we've had through December.
Today features a potent, fast moving system working into the Ohio Valley. This bad boy will cause our winds to really increase and should also spawn some showers. Highs today will hit the 50-55 degree range.
Let's track the showers...
Those scattered showers will linger into very early Saturday morning as some cooler air moves in. Temps MAY get just cold enough for a wet flake in the mountains early in the day. This scoots on out of here quickly during the afternoon and this will set the stage for a calm New Year's Eve. Temps will be cooler than today with highs in the mid 40s and readings in the 30s as we say hi to 2012.
That brings us to New Year's Day and the big change blowing into town. This is when an arctic front crashes through the region with gusty winds, a few showers and falling temps. Readings will start in the 40s and fall into the 30s by the end of the day with a few snow showers taking over.
The cold air will then really kick in Sunday night through Tuesday as a deep trough engulfs the eastern half of the country. Highs in the 20s look good for Monday and Tuesday with lows dipping into the low and mid teens by Tuesday morning. Winds are also going to be VERY gusty and this may create wind chills nearing 0 at times. BRRR!
What about the snow? This is the type of setup that produces snow showers and squalls and that's likely to be amplified by the totally unfrozen and warmer than normal Great Lakes. This cold air pouring over the lakes will pick up more moisture than normal and that means areas downstream will see the white stuff kicking up.
Here's the GFS showing the increase in snow...
Look for the GFS to really start picking up on the snow shower and squall threat as we get closer. The GFS Ensembles seem to have a decent handle on the moisture...
Don't be surprised to see snow flurries flying all the way into northern Georgia with this type a setup.
I am also keeping an eye out on a clipper for Wednesday into Thursday. The Canadian Model is the most robust with this...
I will have another update for all you snow and cold starved winter lovers later today. Have a great Friday and take care.
