Well, we already know a winter storm is approaching the area tonight. Let’s take one more look at the set-up. One low-pressure system is coming from the west moving east. Another low-pressure system is riding up the East coast. Low-pressure system #1 is going to weaken as it approaches Low-pressure System #2, and transfer #1 energy to #2. This will cause low-pressure #2 to strengthen rapidly cause heavy precipitation and high winds along the coast and inland areas. This big question is how much snow. College Park and Washington D.C are both on the edge between a lot of and a small amount of snow. However, The University of Maryland has already announced it is closed for tomorrow. For more in depth snowstorm coverage go to our earlier post here.

The high will be in the mid-30s with Northwest Wind at 15-20 mph with gusts up to 30 mph. With the University closed tomorrow people should stay home until late afternoon. Tomorrow evening temperatures will drop to low 20s. Watch for slippery spots on the road as anything melted will re-freeze.
