2010 extreme

It was windy for a little while here. LoL at that meso a few minutes ago between Herndon and Reston.

FFC should have issued flood watches for at least the southern portions of the Atlanta metro area this morning as it was becoming clear that these heavy bands on the western side storm would interact with the front was being shown by a lot of the guidance.  Most of the area currently under the flood waning was never under a watch.

DCA: 11/15

BWI: 10/25

IAD: 10/21

RIC: 11/9

Tiebreaker: 3.42

This is the third time in about the last month that a small and relatively isolated storm has popped up over Burke in a weak flow environment with boundaries as the main forcing mechanism.  Reminds me of 2012 when that also happened several times.

I was driving and never felt it.

It was at this time mid night sunday morning walking north on my street in nearly knee deep snow I could see clear sky to my west and and a definitave back edge of the clouds looking east as the last flurries were flying. It was a spectacular end to the storm.

It was at this time friday evening snow had started to overspread much of the area.

That storm was a nearly perfect miller a for ma, very similar to Feb 1983. The storm already had an eye and tons of moisture ahead of it before before it made land fall in western Florida! I was supposed to work from 10am to 6pm that day which was the time the worst would be. Im glad I called out even they were pressuring me to come in that morning because by the evening there was a solid 18-22 inch wall of snow between the main road and my street. Since I drive a corolla that would have been a disaster.
