Snow will develop from south to north between 6 PM and 8 PM.

Heavy snow with continue through Thursday morning with snowfall rates of one to two inches per hour.

**Before any mixing begins along the interstate 95 corridor, there will be a 7 hour window of at least one inch per hour snowfall rates and it is because of this that 8″ of snow at DCA is likely with much higher amounts in our close in suburbs**

Short Term Model
Short Term Model predicts at least 4 to 6″ on the ground by 7AM Thursday inside the Capital Beltway

Sleet will likely mix in with the snow from the interstate 95 corridor points east during the late morning and afternoon hours on Thursday.  As the Nor’easter deepens and wobbles slowly along the coast, colder air will begin rushing back in from the west changing any mixed precipitation back to snow.

Snow will end from southwest to northeast on Thursday during the late evening hours. Flurries may continue falling through midnight on Friday!

As this storm really begins to deepen overnight and Thursday morning and the exact track becomes clearer (50 mile shift east or west in exact storm track makes a huge difference in snowfall totals)… there may be some surprises across the DC Region. This system will likely be the largest snowfall DC has seen in four years.

One thought on “Historic Storm for Some

  1. Very interesting. Will bad position of NE high win out and bring in enough warm air to change us to sleet or freezing rain? At least Norfolk started out with a few hours of snow, so it will be a big fight to do so. Hard to imagine less than 8-10 inches. May also get dry slotted for a time tomorrow as well, but should still get nice period of accumulating snow when the upper low come thru in late afternoon.
