Monday December 9 2019

One batch of rain has already moved through and is passing east, while some freezing rain has passed to our west. In between you might have some fog this morning. This is a signal of warmer and more moist air building in. The next push of rain arrives mid day through this evening, and it will be heavy at times.

The big story will be the big swing. Some spots will continue to warm and could be close to 60ºF Tuesday morning. By Tuesday night the colder air will begin to change the last part of this storm over to snow. Temps will drop fast, but will it be fast enough to allow for stickage on the roads?


Monday Morning Weather


  • This Afternoon: Rain may be heavy
  • Tonight: Temperatures warm through the 50s
  • Tuesday: Temperatures could hit near 60ºF
  • Tuesday Night/Wednesday Morning: Snow spreads across most of the region 
  • Will The Snow Stick? Inland areas will drop below freezing, but cities will not. Snow can stick in mild areas if the intensity is hard enough.  That will be the challenge in the forecast. The amounts could range from a coating to a few inches (at least on the grass)

Wednesday Morning Close Up

NAM 3 KM Model– This is actually the warmest solution.

  • In my next report, I will contrast the modeling to show the spread of potential timing and intensity.
  • It will snow for most of the region.

The most likely spots to have stickage on the roads will be in southern PA. In Maryland: western Montgomery, Frederick, Carroll, western Howard, northern Baltimore, and northern Harford Counties. Metro Baltimore and spots near the water still need to be monitored for intensity to overcome the warmer air/ground.
