January 12 Weather Mild Few Days Then A Little Snow This Weekend

Tuesday January 12 2021

After a seasonably cold day, we warm up in the middle of the week.   Some areas could get up close to 50ºF, then we get the cold front on Friday.  As we get better information ‘in the grid’, there is more support showing the timing of the moisture and cold air.   As of now, it looks like rain will mix with snow Saturday morning, then more of us get into the snow showers later that day.

This is just the first push of cold air, there will be more over the next few weeks.

Morning Surface Weather

You may have thick frost on your car, but this southern storm will be staying south and moving off of the coast.

This quick look shows the time of interest: Late Friday into Saturday

 

 

Friday Afternoon 

The cold front will arrive, but the cold air (cold enough for snow) will be delayed by up to 10 hours.

 

Saturday Morning Snow

This is Cold Front snow. That means it is brief, and often either falling on warmer ground or just enough for a coating. If there is more, it would be west and north of Baltimore based on this outlook.

 

 

Saturday Evening Snow

This is from an upper level disturbance, like a Clipper.  That can produce more widespread snow showers, and a quick coating.

Note: There will be Lake Effect Snow around Buffalo. The Ravens may very well be playing in the snow this weekend.

 

 

 

Temperature Outlook

Note: This is for Baltimore at BWI.

The high temperature on Saturday is likely at midnight, before the cold air fully arrives.

This looks less extreme that earlier plots.  I will expand on this in a report later today.
