January 5 2017 3:15 PM Update – A Winter Weather Advisory has been issued by the National Weather Service for Thursday evening until Friday morning. There is a slight variation in time between Maryland and Pennsylvania counties, but essentially just after sunset until before sunrise Friday. Theses areas can expect between 1 and 2 inches of snow and sketchy roads for late activists and night classes. Local schools may announce postponements out off caution. It is our first event of the season on a weekday after all.  Farther south may have slightly less, but still worth a concern for conditions.  I have the latest radar simulation below. I want to caution two main points here:

  1.  Flash Freeze: Metro areas with snow starting near or just above freezing may have less snow but are at more risk for a flash freeze on the roads. Even with pre-treatement, initial snow may melt, then freeze with steady snow and falling temperatures. Areas north and west that start colder will have just snow to deal with.

Initial Temperatues

2.  The Advisory above does not include Washington, Annapolis, or places in between at this time.  But that does not mean they are in the clear. A little bit of snow, even an inch or less can still cause slick problems, with the flash freeze I mentioned above. So this area along wth Howard and Anne Arundel Counties need to be watched.

If there is a need to update the priory’s snow map, I will post that this evening. Still plan on a general 1 to 2 inches in the Advisory Zone and up to 1 inch in other areas.

Morning Temperatures:

Note the drop in temps staying well below freezing. The morning will be slick, but local roads are subject to your local crews…

Will School Be Delayed?

Well, the snow should be done by 3 or 4 AM, but freezing temps will keep icing conditions around. The condition of the roads will depend on your local road crews. Sometimes less is more of a problem… but no promises. Kids must do all of their homework or risk jinxing any chances to sleep in.
