mitchnick Posted February 1, 2014 Share Posted February 1, 2014 fwiw, Euro skewts are finally out on Accuwx, and the good news is......there's no warm level at 800mb at IAD or BWI at 48 hrs (Monday 12Z) and both locations are isothermal freezing from 48 hrs thru 54 hrs (54 looks 31 degrees isothermal)!!! DCA is sooooo close to isothermal freezing at 48 hrs, it too should be all snow; by 54 hrs it is isothermal freezing too so, Euro is not as bad as I thought and definitely colder than last night's run Link to comment Share on other sites More sharing options...
blueapple Posted February 1, 2014 Share Posted February 1, 2014 Shortly after that it might transition to sleet. Somewhere around 15Z it probably goes to snow. And according to the latest NAM, there is only about .1 -.15 falling after 15z. Link to comment Share on other sites More sharing options...

Heisy Posted February 1, 2014 Share Posted February 1, 2014 Without precip type maps yet it is hard to say how much of the precip fell as snow on the RGEM since it comes out in 12 hour intervals Link to comment Share on other sites More sharing options...

BTRWx Posted February 1, 2014 Share Posted February 1, 2014 And according to the latest NAM, there is only about .1 -.15 falling after 15z. After seeing Bufkit, it's even less than that for snow and more sleet within that .1 - .15. Link to comment Share on other sites More sharing options...

Heisy Posted February 1, 2014 Share Posted February 1, 2014 Is this our wettest winter storm in 3 years? Whats funny is that here in Philly we might get more QPF than the recent storm that dropped a foot of snow here, but we might only get 4-5" because of ratios. I hope you guys get a superband that keeps the column cold and someone gets a surprise. Link to comment Share on other sites More sharing options...
84 Hour NAM Posted February 1, 2014 Share Posted February 1, 2014 Well, RGEM has been fantastic this year, hopefully that continues here. Link to comment Share on other sites More sharing options...

Bob Chill Posted February 1, 2014 Share Posted February 1, 2014 18z RGEM is ~13mm snow at DCA I don't have highres stuff yet but should be up in less than 30 mins. I can't deal with those maps from the source. They scare me. Link to comment Share on other sites More sharing options...

mitchnick Posted February 1, 2014 Share Posted February 1, 2014 The top link above my 48hr img is that... its snow yep, and you know it changes over before the 48th hour, so some of that that has fallen is snow and based on 700mb RH map, DCA and east is still under the high RH at 48 hrs Link to comment Share on other sites More sharing options...

mitchnick Posted February 1, 2014 Share Posted February 1, 2014 What is 13mm snow = in inches roughly, multiply mm times .4 so 13 x .4 = .52" Link to comment Share on other sites More sharing options...

NorthArlington101 Posted February 1, 2014 Share Posted February 1, 2014 Just messing around, Im no map maker as you can see, but Ill go with something like this Capturemdatlmap.JPG Shouldn't DC be 1-3?

Bob Chill Posted February 1, 2014 Share Posted February 1, 2014 Rgem is good with ns stuff. I don't have much of an opinion for moist southern storms. It was pretty darn good with 1/21 so there's that. It seems to wanna go bonkers with this storm so it gives me some pause. Link to comment Share on other sites More sharing options...

dallen7908 Posted February 1, 2014 Share Posted February 1, 2014 When I moved to the area, I headed to Oakland, MD to go skiing. The forecast was 3-6 " for Allegheny County and 12-18" for Garette. I assumed the discontinuity was an error. It wasn't and it verified. Snow started accumulating just west of Frederick. Why are the 850 temperatures so high? Is the 850 low going north of us? I guess it shows you have to worry about 850 first. Still hoping even east of the fall line. Link to comment Share on other sites More sharing options...
