welbane Posted March 3, 2014 Share Posted March 3, 2014 Snowfall map in cm's support the idea that a narrow band across the DC is the jackpot with 25-30 cm, that is, 10"+. http://www.instantweathermaps.com/GFS-php/showmap-conussfc.php?run=2014030300&time=PER&var=ASNOW&hour=024 Link to comment Share on other sites More sharing options...

I guess it is colder too which compensates some in the snowfall department. You have to look at the 24hr at 30 on the 18z. They are basically identical.

That is an important consideration..10+ was progged pre 0z for most all of us IIRC Link to comment Share on other sites More sharing options...

So any site that was using the old RAP is now using new RAP since it is being disseminated as such. thank you. The RAP V2 did indeed replace the older version. NCEP certainly can't afford to run multiple versions. Link to comment Share on other sites More sharing options...

HighStakes Posted March 3, 2014 Share Posted March 3, 2014 On 3/3/2014 at 3:52 AM, ravensrule said: I think we are good for 7-8". BWI gets .70 qpf. between 6z and 18z compared to Westminster at .37 qpf. during the same period. You are somewhere in the middle. So 7-8 is very much in play for you.
