I think DC metro + all suburbs will like it. Your daughter needs to understand that sacrifices must be made. 12 2 Link to comment Share on other sites More sharing options...

CoastalWx Posted Sunday at 02:14 PM Share Posted Sunday at 02:14 PM NAM is definitely a sharp cutoff near PA border. However, mid level fronto/deformation sort of lingers there in the nrn burbs. I think that will help accumulations there while DC flirts with crappy flakes or IP/FZDZ for a time before the mid level low moves in. 3 Link to comment Share on other sites More sharing options...

Seems maybe due to weaker shortwave. Confluence is actually backed off notably even vs 6z run. But shortwave can’t pull in as much moisture perhaps. 3 Link to comment Share on other sites More sharing options...

Confluence is actually backed off notably even vs 6z run. But shortwave can’t pull in as much moisture perhaps. Haven't dug into it a ton, but at first glance, this observation plus a weaker/flatter 850mb jet is resulting in less WAA at low levels (more WSW orientation aimed at the Eastern Shore, not more SW aimed at the Mason-Dixon) is one of the culprits. I still see some 700mb FGEN up near the M-D so that's why some of these totals aren't too sharp on gradient to the north and still reach warning criteria for parts of northern MD, but should that trend weaker, then that northern area (while having high SLRs) will be squeezing out every bit of moisture to meet warning criteria. 9 Link to comment Share on other sites More sharing options...

TSSN+ Posted Sunday at 02:37 PM Share Posted Sunday at 02:37 PM Here is something to watch very early to see how accurate nam is. It has no snow reaching the southern counties of Iowa and they are under warnings for 4-8”. Let’s see how that pays out over the next few hours. 7 Link to comment Share on other sites More sharing options...
