TSSN+ Posted December 3, 2013 Share Posted December 3, 2013 Intresting evloution on the 12z GFS in that the GL cutter shortwave folds to the PV coming out of Hudson Bay, leaving a large pos tilted cold set-up with precip running up the old front. Edit: Meanwhile, -30 850T into Chicago :brrr: Ya it gets pretty cold post 174. -10C at surface and 1044mb high in the southern Plains. Link to comment Share on other sites More sharing options...

lsukev Posted December 3, 2013 Share Posted December 3, 2013 Vodka Cold at 192... -22 to -24°C at 850mb. Lows in single digits for DC Dec 11th? Wow. Link to comment Share on other sites More sharing options...
WxUSAF Posted December 3, 2013 Share Posted December 3, 2013 Lows in single digits for DC Dec 11th? Wow. That would come in handy for erasing the +15 or whatever we hang up on Thursday. Of course, IAD would probably be 4F in this scenario while DCA gets down to 18F. Link to comment Share on other sites More sharing options...

Bob Chill Posted December 3, 2013 Author Share Posted December 3, 2013 GFS is faster and obviously deeper with the cold but the euro has plenty of teens in the d8-10 range. Coldest air of the year is getting close to a lock. Single digits? I'll take the over....for now.. Link to comment Share on other sites More sharing options...
wxmeddler Posted December 3, 2013 Share Posted December 3, 2013 Wow, BWI gets .89 of SN/IP per soundings on the Sunday CAD. DCA is rolling out next. Link to comment Share on other sites More sharing options...
clskinsfan Posted December 3, 2013 Share Posted December 3, 2013 Weatherbell loves the Winchester area. They've already had like 300" of model snow this year. We all know how model bullseyes work out. But the GFS is a very nice storm out this way. Lets just lock this one in now. Link to comment Share on other sites More sharing options...

Bob Chill Posted December 3, 2013 Author Share Posted December 3, 2013 The GFS is keying in on a totally different wave now no? I think it's allowing another wave to form because of the crazy gradient building between arctic air and the se ridge. Look at h7. make sense in model land. But its a pioneer here so heh...

Bob Chill Posted December 3, 2013 Author Share Posted December 3, 2013 The GFS is keying in on a totally different wave now no? Look at hr 153 @ h7 and click forward in time. It's just a new slug with some lift. I suppose it's possible. Pattern is way amplified in a way we haven't seen in a long long time. ETA: Note the moisture originates in TX. It's like a vacuum hose pulling off the gulf on the boundary. If the boundary was so anomalously south there would be nothing. An arctic boundary sinking to tx-la in early Dec is not something I have much experience with. Link to comment Share on other sites More sharing options...
WEATHER53 Posted December 3, 2013 Share Posted December 3, 2013 November had it's mild suirges like this week. 6th & 7th 68&65, 10th 66, 15th&17th 61 &65, 18TH 71`, 22&23RD 63 & 59. Cold shots followed, it was a cold month. Sunday event still way to far out to index to 6 hour model runs. Link to comment Share on other sites More sharing options...

NJwinter23 Posted December 3, 2013 Share Posted December 3, 2013 looks like the Low is so far to our west, we don't get the strong push of warm air into our area so surface temps hold on to the cold longer than earlier runs, but eventually it gets real warm The GFS is keying in on a totally different wave now no? Yup there is an entirely different wave shooting ahead/out of main southwest trough that gets you guys Sun morning while high is still in prime position. Would be nice if that is correct.

WEATHER53 Posted December 3, 2013 Share Posted December 3, 2013 There will be an area of -20F surface temps across northern tier by early-mid next week. Although it is "rollover" cold it will create departures of -20, or colder, around DC. Link to comment Share on other sites More sharing options...
