I remember a storm last winter or the year before where that was your post repeatedly about a storm threat. Annoyingly, you were mostly right that time! lol Honestly I do not think dry air is that big of an issue on this one. I think it is more about the trajectory of the heavy precipitation. That mostly goes well to our north west into the Ohio Valley And West PA. So basically I think the precipitation coming our way kind of Is getting sheared out and getting weaker as it comes Northeast. At least that’s how the models see it to a degree 2 Link to comment Share on other sites More sharing options...

It can be useful for determining how the most recent run is doing with precip placement. As you can see, the 02z HRRR does not have the light returns as far north as they actually are. More images can be found here https://jmmweather.com/hrrr/ LOL did I pay you to make this? 1 Link to comment Share on other sites More sharing options...
nj2va Posted February 20, 2019 Author Share Posted February 20, 2019 Wow at the 00z GFS. DC loses 700mb just before 18z and 0.5”+ QPF has fallen by 18z. I’d side with the 3k/Euro blend vs the GFS at this point but nice to see GFS in the RGEM camp with a nice thump for DC. 4 Link to comment Share on other sites More sharing options...

At least that’s how the models see it to a degree 0Z models do not show that so far. Don’t look at the snow maps— just look at precip total maps through 18Z tomorrow. The aim of the heaviest precip is not where you described. 1 Link to comment Share on other sites More sharing options...

Sounding at 18z at DCA looks isothermal up at 700mb... so just barely hanging on to snow if its pounding IMO 1 Link to comment Share on other sites More sharing options...
clskinsfan Posted February 20, 2019 Share Posted February 20, 2019 This is going to start on the earlier side of projections IMO. Snow is progressing nicely up the Shenandoah Valley. My projected start time is between 1-3 and I would lean towards closer to 1 than 3. 1 Link to comment Share on other sites More sharing options...

nj2va Posted February 20, 2019 Author Share Posted February 20, 2019 FV3 agrees with the GFS with a flip just before 18z in DC. Probably about 0.4” of snow on FV3 for DC. 3 Link to comment Share on other sites More sharing options...

nj2va Posted February 20, 2019 Author Share Posted February 20, 2019 00Z HRDPS is a beatdown. It has snow reaching DC between 5-6a. Sleet line still SW of the city through 18z. 0.75” has fallen in DC by then. Lol 3 Link to comment Share on other sites More sharing options...

real Posted February 20, 2019 Share Posted February 20, 2019 I actually think last-minute forecast semantics in a storm like this a bit ridiculous. Fact is most nornal people really don’t differentiate between 2 and up to 5. Less than 2 they would consider a bust. More than 5 they would consider surprising but not end of world considering it will be raining by late afternon. More than 8 would start to be viewed as upward bust. 1 Link to comment Share on other sites More sharing options...
