NJHurricane Posted January 21, 2012 Share Posted January 21, 2012 Hopefully everyone has seen my offices facebook page and has 'liked' it. There are good posts (with soundings) on there today. Have liked it...have pointed friends and family to it...was expecting it to be a conduit for warnings, reports, and weather trivia, but the detailed posts with model data and explanations have far exceeded my expectations. Between Hurricane Schwartz showing 500 mb maps and explaining the NAO on air and your office on facebook dropping knowledge, the Philly area could become the most informed consumers of weather info in the east. Nice job. Link to comment Share on other sites More sharing options...
fsu_wxgirl Posted January 21, 2012 Share Posted January 21, 2012 I know this isn't a PA observation, but I was surprised to hear my family in Centeal Va is getting fairly heavy sleet right now. They are located about 30 minutes south and west of Richmond, Va. Link to comment Share on other sites More sharing options...

fsu_wxgirl Posted January 21, 2012 Share Posted January 21, 2012 per obs in the mid atl thread cho is getting snow, didnt think it would be that far south. Yeah me neither. I haven't looked at any upper air charts but the radar looks like they are receiving fairly moderate precipitation. I'm wondering if it's falling hard enough to drag down some colder temperatures allowing the precip to change to sleet and snow. Link to comment Share on other sites More sharing options...

fsu_wxgirl Posted January 21, 2012 Share Posted January 21, 2012 interesting to note...how many miles further south is this than progged? I originally forecasted Northern Virginia. I thought Richmond would be too far south. They're receiving good southerly flow so I don't expect them to stay in sleet though the night. They should change over to rain.

famartin Posted January 21, 2012 Author Share Posted January 21, 2012 per obs in the mid atl thread cho is getting snow, didnt think it would be that far south. LWX's sounding was solidly snow (despite the warm layers) back at 0Z. Link to comment Share on other sites More sharing options...
famartin Posted January 21, 2012 Author Share Posted January 21, 2012 Regarding the snow and sleet reported further south... I'd have to guess that this is a feature of a stronger/faster warm advection-related precipitation band than anticipated by the models (shocker). In the attached image, you can see the 12Z GFS QPF from 0Z-6Z on the upper right, and the latest radar image elsewhere. Note how much further ahead the southern band (circled in pink) is compared to the northern band, whlie the GFS progged them to be on a similar pace.

Thunder Road Posted January 21, 2012 Share Posted January 21, 2012 6.4" storm total. Nice event. Precip overperformed here and shifted south somewhat last minute, so that should bode well for you guys Photo album back when we only had 2.5". I'll post more pics tomorrow. http://www.facebook....=1&l=78d5883e11 Good luck to you all! Link to comment Share on other sites More sharing options...

Very cool, so does this help enhance or degrade the situation for this storm, i mean does it pull up more warm air aloft, or increase qpf? Link to comment Share on other sites More sharing options...

It may well do the latter, though I'm hessitant to say it will do anything for sure. Link to comment Share on other sites More sharing options...

SmokeEater Posted January 21, 2012 Share Posted January 21, 2012 MESOSCALE DISCUSSION 0036 NWS STORM PREDICTION CENTER NORMAN OK 1159 PM CST FRI JAN 20 2012 AREAS AFFECTED...SRN AND CNTRL PA CONCERNING...HEAVY SNOW VALID 210559Z - 211000Z HEAVY SNOWFALL IS EXPECTED TO DEVELOP ACROSS SRN AND CNTRL PA LATER TONIGHT. SNOWFALL RATES COULD REACH 1 INCH PER HOUR ACROSS PARTS OF THE MCD AREA. WATER VAPOR IMAGERY CURRENTLY SHOWS A SHORT-WAVE TROUGH EXTENDING FROM THE ERN GREAT LAKES SWWD ACROSS THE OH VALLEY. A LARGE AREA OF PRECIPITATION IS LOCATED JUST AHEAD OF THE AXIS OF THE SHORTWAVE TROUGH FROM SRN OH EXTENDING EWD INTO THE CNTRL APPALACHIAN MTNS. A THREAT FOR FREEZING RAIN OR SLEET MAY EXIST ACROSS SW PA FOR A FEW MORE HOURS DUE TO WARMER AIR IN PLACE SOUTH OF THE PITTSBURG AREA. HOWEVER...FROM PITTSBURG EWD TO NEAR HARRISBURG...THE PRECIPITATION SHOULD BE ALL SNOW WHERE FORECAST SOUNDINGS SHOW TEMPS BELOW -10C IN THE 850 TO 700 MB LAYER. IN ADDITION...MODEL FORECASTS MARKEDLY STRENGTHEN ISENTROPIC LIFT ACROSS SRN AND CNTRL PA LATER TONIGHT AS THE SHORTWAVE APPROACHES FROM THE WEST. THIS SHOULD RESULT IN ENOUGH LIFT FOR HEAVY SNOWFALL WITH SNOWFALL RATES REACHING 1 INCH PER HOUR MAINLY DURING THE OVERNIGHT PERIOD. ..BROYLES.. 01/21/2012 Link to comment Share on other sites More sharing options...
