DDweatherman Posted February 11 Share Posted February 11 For comparisons sake, look at 18z 12k Nam hour 9 vs hour 15 from 12z. Safe to say we really shouldn’t use that model whatsoever (for anyone that didn’t already know) 1 Link to comment Share on other sites More sharing options...

Similar bands and snowfall rates will be possible through early evening. DISCUSSION...Regional radar imagery shows an organized precipitation/snow band developing from west-central VA into the Chesapeake Bay area. Recent snowfall reports from central VA and surface observations reporting visibility reductions between 0.25 to 0.5 mile suggest moderate to heavy snowfall rates are ongoing. This band is largely being driven by a combination of strong warm-air advection and frontogenesis within the 925-700 mb layer and may persist for another hour or two given the strength of forcing for ascent. Additional banding is possible heading into the late afternoon hours as a weak mid-level impulse - and the primary precipitation shield - migrates into the region and to the north/northeast into northern MD and DE. Recent guidance suggests heavy snow potential will likely peak across the Chesapeake Bay area during the 21-00 UTC period. Although surface temperatures across this region remain near/above freezing, dewpoints in the 20s suggest that temperatures will likely fall to below freezing due to low-level evaporative cooling associated with the onset of precipitation, which should support heavier snowfall rates later this afternoon. ..Moore.. 02/11/2025 ...Please see www.spc.noaa.gov for graphic product...

HRRR and RAP at this point both do have another light round in the AM before flipping to ice, which LWX hinted at in their last AFD 2 Link to comment Share on other sites More sharing options...

Jebman Posted February 11 Share Posted February 11 South Cen Texas has gotten 3 to 4 inches of rain. One inch was forecast. Sending the moisture over to the Mid Atlantic, in the form of heavy snow, with a lot of love!
