NCSNOW Posted January 22, 2016 Share Posted January 22, 2016 If I could find one, we ought to keep track of current 850 temp map by the hour and see how it's matching up with nam forecast. Surface is the least of my worries and probably everyone to my east and north. Wetbulb is in low 20s and seeing nothing but moon and stars. Have noticed the chimes starting to make a little noise. HP is just now sliding into position to start nosing the ne wind down this way. ALSO read that the nam initialized wrong and tried to shoot the current lp in Louisiana up a convection line / feedback issue. Link to comment Share on other sites More sharing options...
Jet Stream Rider Posted January 22, 2016 Share Posted January 22, 2016 The low in Mississippi on mesoanalysis is 3 mb weaker than what NAM is showing at this point, FWIW. And the NAM initialized too far north with that slp it appears. Also the NAM does a funky retrograde loop of the slp later when its up in Delaware bay. Absolutely blasts Long Island and Cape Cod!

Cheeznado Posted January 22, 2016 Share Posted January 22, 2016 Just pulled into AVL, rain mixed with a tiny bit of snow. I noticed the NAM is persistent with the warm nose at 800mb- going to be close to mixing with sleet which may cut down the accums a tad. Link to comment Share on other sites More sharing options...

NCSNOW Posted January 22, 2016 Share Posted January 22, 2016 what site do you use for converting wet bulb temps? Old school math. You got hooked on that common core math and now look at you having to rely on computers and calculators. Seriously I can give you formula, but the best is the mesowest site. Just punch in NC and play with radius. It has all kinds of features and updates hourly from all the reporting stations. You can see the lower dps in va coming down, wind trajectory etc. Link to comment Share on other sites More sharing options...
KeepPounding Posted January 22, 2016 Share Posted January 22, 2016 hrrr doesnt look bad at all for upstate into nc, snow in rdu thru 11am. calm down. I thought precip amount looked great but I didn't believe the precip type showing and totals after comparing current temps and what it thinks they will be only a few hours down the road. Nowhere close to the end of the run. I know others want to compare past NAM etc...to see how good they did. It seems just as prudent to look at temp profiles on HRRR and RAP if people are using any accumulation amounts from them. Link to comment Share on other sites More sharing options...
NEGa Posted January 22, 2016 Share Posted January 22, 2016 hrrr doesnt look bad at all for upstate into nc, snow in rdu thru 11am. calm down. its easy to get the prestorm jitters because as those of us in the se know, whatever can go wrong with our winter storms usually does lol. however that looks pretty decent to me at this point, and shows close to what has been on the models lately (although i am speaking mainly for mby of course, ne ga and the upstate) Link to comment Share on other sites More sharing options...

NCSNOW Posted January 22, 2016 Share Posted January 22, 2016 Unisys has current 850 temps at -7 on nc/va border and -2 on nc/sc border right at Carowinds goes above freezing down i85 from there before you get to anderson sc. My laptop is wuth I.T. guy at work,ugh so don't have all my links. Link to comment Share on other sites More sharing options...
beanskip Posted January 22, 2016 Share Posted January 22, 2016 21 mm of Shelby's 36 mm of precip just turned into rain on the 0z NAM -- surely some sort of blip given that the 18z GFS had such cold 2m temps for the duration of the event (down to 24.6F) while NAM is only at 31 during bulk of precip.

beanskip Posted January 22, 2016 Share Posted January 22, 2016 Also a very slight warming trend on 0z RGEM, but relieved to see it keeps I-85 corridor 2ms (and for most of the run 850s) below freezing throughout. Link to comment Share on other sites More sharing options...

NCSNOW Posted January 22, 2016 Share Posted January 22, 2016 Everyone in NC has a NE wind currently at surface except Asheville, looks S or SE. But think that's common at their airport alot. Maybe the topography, valley Configuration. Anyway this will help calm nerves in upstate Link to comment Share on other sites More sharing options...
strongwxnc Posted January 22, 2016 Share Posted January 22, 2016 Yep. 2M temps looks good through out on the 00 run Also a very slight warming trend on 0z RGEM, but relieved to see it keeps I-85 corridor 2ms (and for most of the run 850s) below freezing throughout.

So not gonna be long till CAD starts moving on in. I'm thinking maybe around 4am or so. Link to comment Share on other sites More sharing options...

Jet Stream Rider Posted January 22, 2016 Share Posted January 22, 2016 Not in love where the new RGEM has the 500mb low tomorrow PM, way up in TN.... Yeah, thats too far north. But currently that 1008 slp wants to go to the GoM. Its trying to go southeast, not north like the NAM showed.. Link to comment Share on other sites More sharing options...
Chrisr4419 Posted January 22, 2016 Share Posted January 22, 2016 What happens if the slp stays south along the panhandle? More cold air moves down? Just trying to learn. Link to comment Share on other sites More sharing options...
strongwxnc Posted January 22, 2016 Share Posted January 22, 2016 Also it has moved SE over the last four hours as shown trends/forecast found on the page. Yeah, thats too far north.
