Monday January 15 2018

Light snow is on the way and the arctic air in place will help chill the ground and support maximum stickage…. Today will just be cold as some flurries may develop. It will be a developing band of snow that slowly moves in Tuesday that will bring us a general 1 to 3 inch accumulation. The issues may being Tuesday morning in western Maryland and north into southern Pennsylvania. This will spread into the Baltimore suburbs Tuesday evening and be an issue for travel on Wednesday morning. Delmarva and the beaches will deal with this most of the day and afternoon on Wednesday. Here’s the quick breakdown.

This Morning

We are in the deep freeze…

 

Today: Flurries

There will be flurries and light snow, but mostly for ambience today.

 

This Afternoon

Deep Freeze Holds: Highs stay in the mid 20s to low 30s. So the ground will be chilled enough for any flakes to stick when they arrive….

Tuesday Morning Snow

The slow moving system on the way could bring morning snow tomorrow to mountains of western Maryland and southern PA. There is potential for snow from Hagerstown to Harrisburg…. maybe into York and Lancaster. This is making a harp cut so this will be something to watch closely for any adjustment.

Snow Tuesday Evening-Wednesday

There will be an evolving and slow moving band of snow. It should reach the northern suburbs of Baltimore by Tuesday evening. The speed of the progress will determine how much will accumulate. I would plan on paying attention to school activities, etc Tuesday evening north of Baltimore. But it will be a Wednesday morning issue for metro areas and Delmarva.
