psuhoffman Posted February 21, 2015 Share Posted February 21, 2015 That ice storm frontal wave in mid January 1994 I thought this looked similar to showed up as the #5 analog on CIPS. Surface cold definitely held longer then expected in that event. There was also some crazy snow totals just north of our area, maybe we can shift that south 50 miles this time.

87storms Posted February 21, 2015 Share Posted February 21, 2015 Winds in the boundary layer will be very light, actually, given the inversion. I'm more concerned that we flip to ZR and struggle to warm 2m temps overnight (esp given the lack of any solar help). The surface itself is an icebox right now. agreed. i have a difficult time believing we'll be warming up quickly tomorrow. it's expectionally cold (like frostbite cold) outside right now.

psuhoffman Posted February 21, 2015 Share Posted February 21, 2015 Did I get un-NAMd? NAM goes from about 6" at Hunt Valley to 12" in Shrewsbury. Gradient is too tight to give exact numbers in between but judge your distance from both and you get a good estimate. Link to comment Share on other sites More sharing options...
mitchnick Posted February 21, 2015 Share Posted February 21, 2015 00z RGEM at 24 -- http://weather.gc.ca/data/model_forecast/512_100.gif Looks... good... just need to wait for better color maps little drier than 12Z, but temps about the same sorta meh, but not bad meh Link to comment Share on other sites More sharing options...

psuhoffman Posted February 21, 2015 Share Posted February 21, 2015 RGEM looks like a very nice hit for DC and Baltimore, as well as places NW from the precip maps. Its an everyone hug it run. Link to comment Share on other sites More sharing options...

Sparky Posted February 21, 2015 Share Posted February 21, 2015 Psu might be thinking of the great sleet storm of 8" we had in Jan 94 but 20 miles north got 15-18".can't remember the exact date ..sorry After looking I think it is 1/17/94... I got 6 inches in 4 hours then it changed to some sleet/zr the remainder of the storm, oops, no, it changed back to light snow at the end.......high 33 low 10.

mitchnick Posted February 21, 2015 Share Posted February 21, 2015 RGEM starts between 10-11AM at both DCA/BWI, is all snow through 7PM at DCA and 8PM at BWI ZR starts at 7PM at DCA and lasts until around 9:30PM when it changes to all rain BWI is ZR by 8PM and changes to all rain between 10-11PM Link to comment Share on other sites More sharing options...

Bob Chill Posted February 21, 2015 Share Posted February 21, 2015 Yes until last storm. Yes but we didn't like it because it was too dry. It's wasn't that far off IIRC Link to comment Share on other sites More sharing options...
Ji Posted February 21, 2015 Author Share Posted February 21, 2015 January 17, 1994 I think topper shutt lied that storm. he said they sent weather balloons up and confirmed that everything in the upper levels were good enough for all snow...then we got 5 inches of miserable sleet Link to comment Share on other sites More sharing options...
