Coach McGuirk Posted February 20 Share Posted February 20 Same pattern as last year, it will get cold when it is dry but when we get precip it is rain. Back to back winters without measurable snow in my time. Bearing a miracle, I did get 1 inch of snow in early April 2007. Williamsburg, Gloucster and Mathews County got 3-4 inches.

NorthHillsWx Posted February 20 Share Posted February 20 So far at RDU, 14 of the first 19 days have been above average for high temps this month, including two days where the daily low temp stayed above the average high temp for the date. Only saving grace has been it’s been relatively dry meaning we’ve had some phenomenal weather days. But we’ve been so far removed from even thinking about snow besides on a weather forum it’s literally become a pipe dream around here Link to comment Share on other sites More sharing options...

GaWx Posted February 20 Share Posted February 20 The last few runs of the GFS hts at 10 mb have suggested the winds getting well down into the second most negative territory for March back to 1959. Although that means it is very likely overdone, it does show how strong a signal there is for yet another major SSW ~March 5th. The 12Z at 384 has a strat HIGH over the N pole (~3,175 dm), where more typically there’s a low there or nearby (the SPV). The SPV on this is very weak (~3010 dm) and is way south in the Atlantic near 53N! It doesn’t get much weaker/displaced than that. So, take the level of weakness shown with a grain. 2 Link to comment Share on other sites More sharing options...
GaWx Posted February 20 Share Posted February 20 From today’s Euro Weeklies, here’s the 10 mb winds: next major SSW ~March 4-5 followed by a dip of the mean way down to -10 m/s during ~3/8-10, lowest this season for any of the progged SSWs beating yesterday’s -8. Many members dip to sub -15. Then the mean stays weak the rest of March. Will the NAO/AO respond by also dipping? 2 Link to comment Share on other sites More sharing options...

StantonParkHoya Posted February 20 Share Posted February 20 Like clockwork. Blocking that is good for nothing. It can never just be 65 and sunny like it’s supposed to be. Link to comment Share on other sites More sharing options...
Bill in MS Posted February 20 Share Posted February 20 Blocking is good for something in the Spring... lots of overcast days with temps struggling to get into the 40's and a large upper low that won't move for two or three weeks. And then a hard freeze on the last night because the sky finally clears about 6 PM... Just in time for radiational cooling to set in. 2 2 Link to comment Share on other sites More sharing options...
GaWx Posted February 21 Share Posted February 21 3 hours ago, CaryWx said: Why should we believe these weeklies now for March? Color me skeptical at this point As bad as all of the models have been, we shouldn’t trust ANY tropospheric model output for over a few days into the future. The strat progs are less unreliable because the strat is normally a bit easier for the models to forecast than the troposphere. But even so, the actual effect of the strat on the troposphere would still be more uncertain. Even if this next SSW along with followup weak SPV were to verify, who’s to say that that would lead to a new round of -NAO and/or -AO? After the major bust of the -AO and -NAO for the current period, I wouldn’t trust them, regardless. And then even if that were to occur, who’s to say that that would definitely lead to a colder E US? 3 Link to comment Share on other sites More sharing options...

BooneWX Posted February 21 Share Posted February 21 I have zero doubt in my mind that this will finally be the moment cold air moves from the long range to the medium and short range. Expect that pattern to persist through June. It does every single year. 3 Link to comment Share on other sites More sharing options...

NorthHillsWx Posted February 21 Share Posted February 21 The fact hours 210-318 on the 06z GFS are all rain illustrates why some doubt it will ever snow again. 1040 high moving into Maine with a trailing wave, blocking, and coastal development with precip back to mountains. Not even a pixel of digital blue. It requires more stars to align for snow here now than for the panthers to win a Super Bowl Link to comment Share on other sites More sharing options...

olafminesaw Posted February 21 Share Posted February 21 Some signs of a few non-accumulating pity flakes Saturday evening from the ULL. The really shocking thing is we haven't even had more than 30 minutes of frozen precip of any kind during the snow drought. I'm sure the same can't be said of the 90s drought.
