DaculaWeather Posted January 17, 2013 Share Posted January 17, 2013 OK... I'm now falling at 3º/hr with NNW winds. Preconditioning if you will... :-) I like using this map http://www.daculaweather.com/current/misc/google-maps-radar/4_google_radar.php Click on "Radar" and "Animate" and a little further down the page, click on station markers and make sure it's set to temp. Then zoom in! Link to comment Share on other sites More sharing options...

Blue Ridge Posted January 17, 2013 Share Posted January 17, 2013 My weenie alter ego wants terribly to clog this thread with by-the-minute reports...I won't let it, but it's a struggle. Sleet/snow mixture is absolutely pouring now, fast enough to accumulate on grassy surfaces. Link to comment Share on other sites More sharing options...

ALTHOUGH THE INCOMING DRY SLOT ON THE SE SIDE OF THE LOWWILL BE WORTH MONITORING AND MAY LIMIT WINTRY TOTALS IN THESOUTHEAST CWA (SEE BELOW). HOW FAST THE COLD AIR ARRIVES ESPECIALLYALOFT REMAINS A CONCERN... ALTHOUGH THE MODELS INITIALIZED WELL ANDARE IN VERY GOOD AGREEMENT...
