Wednesday Morning Update
Today is the Winter Solstice and it is about to truly feel like it. I have been hearing from doubters and all I can say is, ‘let’s talk again on Friday’. The storm will cover 2 days for us, with the back end being the worst.
However, a Winter Weather Advisory and Winter Storm Warning have been issued for tomorrow morning in the mountains. We will be warm with mostly rain, then an arctic blast will bring most of our region below freezing by noon on Friday.
The Flash Freeze is a real threat, not a hope. Please just be cautious of the true potential.
Winds will gust to 40 mph and wind chills will drop below zero leading to a frigid Christmas Weekend.
Headlines
- Today: Winter Solstice
- Thursday: Winter Weather Advisory (Hagerstown), Warning (Garrett County)
- Friday: Arctic Front Arrives BEFORE Noon. Rain to brief snow, wet roads may ice over.
- Christmas Weekend: Bitter Cold Teens/20s.
Morning Temperatures
The cold air in place is seasonal, but colder winds will hold temps down this afternoon.
Morning Surface Weather
The storm may not look like much this morning, but it will be taking form today. The main energy includes air from Siberia and Alaska entering Montana this morning.
Arctic air already in Montana and North Dakota, temps in the -10s. Wind chills in northern states will drop close to -50ºF.
Afternoon Temperatures
Close to where the last few days have been.

Winter Weather Alerts
- Winter Weather Advisory: Hagerstown and Winchester
- Winter Storm Warning: Garrett, Allegheny County and higher mountains: 3 to 6 inches of snow plus ice
Morning Temperatures
The freezing line is highlighted north and west of Baltimore.
Weather Event
With a faster arrival, there will be slightly colder air to allow the start as snow. This may reach parts of Frederick, Carroll, and York counties. But those temps will be marginal. It will be around I-81 and west where stickage could be a problem.
7 AM
Some morning issues west of the I-68 split and south of Hagerstown on I-81.
10 AM
Some minor issues west and north of Frederick. More concern along and west of I-81.
Afternoon
Gradual thaw, except in the Winter Storm Warning area that may remain icy longer.
Temperatures Warming All Night
Friday Morning
Temperatures: Flash Freeze
7 AM to Noon (in slower motion)
The warmest part of the day will be early morning. Then the arctic front arrives, which has been trending earlier.
It looks like local areas can plan for 8 AM to 11 AM (to the Bay) for the Freeze, and expanding to the Beaches by mid afternoon.
Temps will quickly drop to the 20s while the pavement is likely to remain wet. This is the concern for icy roads.
GFS Model
Thursday morning to Friday afternoon.
This is the most aggressive with snow, because it develops a Low Pressure wave along the front. If this verifies, the snowfall would be up to 1 inch.
That is debatable. The main issue is keeping moisture falling and roads wet to allow for freezing.
Wind Forecast
We could see gusts to 40 mph. Yes, that can dry out the ground, when the precipitation stops. But with the cold it will hurt!
Temperatures
Deep freeze to the beaches by afternoon.
Wind Chill
This is the painful part of the forecast. We will all feel this in the afternoon!
Christmas Weekend Deep Freeze
Saturday Morning – Christmas Eve Day will be FRIGID!
7 Day Forecast
The coldest air will settle in over the weekend. There is a small chance for flurries in the cold air, but do not expect local accumulation.
