Tuesday Evening: January 29 2019

The snow is moving east and already ending on the western side of the Bay. Most Winter Weather Advisories have been cancelled. The northern counties got an average of 1 to 3 inches and justified the early school closings. Central Maryland has been in the transition zone, but I hope my reports helped prepare you for the change over that many had between 3 and 5 PM. I will have a final snow report tomorrow. But we are not done yet. The second front is the arctic boundary that brings us the air from the infamous and over blamed Polar Vortex. There is more work to do on this larger weather event.

Getting Colder!

The post tracks the snow across the Eastern Shore tonight, and the cold air to follow. The flash freeze I mentioned still applies as many areas will be down into the 20s or teens overnight. Whatever is wet and not treated will turn to ice. Many schools are calling delays for tomorrow morning, just to allow more work on the roads.

On Wednesday we also have the arctic front, that will arrive mid day. It could bring a quick burst of snow around lunchtime, then temps really tank! The cold air and dangerous wind chills may be another school factor Wednesday night and Thursday morning.

This Evening Snow

Did you read my post earlier stating the models were having trouble with this storm? Here we can see the snow is advancing about 1 hour faster than the HRRR Model forecast. I am showing that slider to compare but all images will verify an hour earlier.

Doppler Radar at 7 PM

The back edge of the snow was moving across I-95. There has been a moderate burst and some stickage on roads that were wet all day. There is a transition to snow along the front that will catch up on the Eastern Shore.

The first image here is the 8 PM forecast, but it matches the radar (above) at 7 PM

The Big Freeze

Temperatures: The quick drop overnight will allow anything that is wet and untreated to freeze. This applies across the state

Midnight

Wednesday Morning

Metro Baltimore will be in the lower 20s. All places that got snow to stick during this afternoon will likely drop into the teens.

Wednesday: Arctic Front

This will cross the area around lunchtime. A brief burst of snow is possible, but the real story will be the drop in temperatures and wind chill.

Wednesday Morning

This is be dangerously cold! Especially for those not accustomed to it.

Close to the record

January 31 (Thur):

42ºF = Normal High; 25ºF = Normal Low
22ºF in 1948 = Record Cold Max Temperature *(Chance to break this)
+4ºF in 1966 = Record Min Temperature *(Chance to break this)

Temperature Outlook

This arctic blast will be short lived AND replaced by a very warm surge next week. While this model shows mid 50s, we could actually reach the 60s. By the end of next week, we should be back colder than average again.
