Folks,

We have FIXED our snowfall maps. You should see a STORM TOTAL amount via our website (...previously it had been just "additional" for today through Monday...). Meanwhile, when we run the ZFP, you should get an additional snow amount today/tonight, as well as the storm total.

Again, sorry about the confusion. DT and others: thanks for bringing this to our attention!

thanks!

MUCH less confusing. Thanks guys for doing that. :thumbsup: You all are rocking today

Noticed the SPC EPV charts were showing some weak negative EPV coinciding with some of that intense frontogenesis over SE Va and the Peninsula. BUFKIT picked up on this as some slight drop of theta-e with height on the ORF time-height section between about 15 and 20kft. I don't have cross sectionals, but I wouldn't be surprised if we see a lightning strike or two in the next few hours, or at the very least, some convectively enhanced snow, as it looks like that's already happened in the past few hours.

Thank you guys for fixing, and staying on top of things.

how much more do you expect for se va?

Just waiting for some rumbles. Checking lightning explorer frequently.

That's a good point. When we looked at it yesterday, the cross sections SE to NW showed a fairly weak "statically stable" environment, i.e. the momentum surfaces were ~ parallel to the saturated theta-e surfaces. Of course, as theses systems wind up off the ATLC coast, inevitably there always seems to be a pocket of theta-e folding with height (leading to slantwise or flat-out upright convection).

Roughly another 4 or 5 looks good to me at this point, given that it looks like you've got another 4 or so hours left of high snow rates. Might be some lighter accums after that, but regardless, it looks like you'll pile up a foot fairly easily, given the 8" you posted earlier.
