Spring snow is possible Tuesday, but impacts should be minimal. 


Enough already! That seems to be the shared sentiment of many after quite a cold and snowy winter in the Nation's Capital. 

Tuesday's snow should be light. The good news is, this late in March, the high sun angle will warm surface temperatures, so not much snow will stick. The roadways will likely be mainly wet, but between one and two inches may accumulate on the grass. Here are a few bullet points of what you can expect tomorrow.

The snow comes as the southern and northern jet stream phase together.  An area of low pressure will develop off the coast of Florida tonight.  The deepening low will track far enough off the East coast that impacts to our area will be minimal. The low will intensify rapidly, 'bombing' out by tomorrow afternoon. The pressure will drop almost 50mb in less than a 36-hour time period. Bombogenesis is a term used when the barometric pressure drops 24 (or more) millibars in a 24 hour period. This is what the strengthening storm looks like.

Since the storm will pass far enough offshore, we'll be spared from heavy snowfall.  Snowfall totals will be less than two inches.  The Weather Prediction Center's probability of snowfall greater than two inches in D.C. is 60%, but I think that would be the highest snow would accumulate. Again, the ground and surface temperatures will be above freezing.

The bigger story this week will be the whipping winds on Wednesday, as the intensifying low pulls off the New England coast. Winds will gust to around 40 miles per hour at times on Wednesday. With temperatures only in the low 40s, it will feel like the 20s and 30s. Highs will rebound into the 60s by Friday. 

So is this our last hurrah of winter weather? My gut says yes! I hope I'm right!
