If you are 300'+ and NW of 95 you will do ok. This storm screams 12/5/2009 and for those who remember that one it was a brutal, just brutal gradient from east to west.
For my location just S of DC barely sniffing 200', for the last 5-10 years any storm that has temp issues like this one has erred too cold and its stayed warmer than modeled. UHI, microclimate, whatever. Just won't bode well for storms like this.
Will be lucky to get 1" unless there is a shift in storm track to the SE.
