A very complex storm system will impact the Mid-Atlantic and New England beginning this afternoon and lasting through Monday. If this had been late March we would have been digging out from….
The current set up for this weekend’s storm reminds me of the March 13, 1993 “Storm of the Century” when an area of low pressure was developing over the Gulf of Mexico and the piece of energy over the upper Mid-West was “the match” that sparked the rapid cyclogenesis off of the east coast… if only it were mid March!
The devil will be in the details, especially regarding how ‘stacked’ the upper level low pressure becomes and exactly where it tracks and stalls. Monday morning will be incredibly interesting across the northwestern suburbs of Washington as temperatures in the lower levels of the atmosphere plummet rapidly. The mountains of PA will likely be buried with at least a half a foot or more of heavy, wet snow on Monday!
Today: Strong Thunderstorms will move through the Washington Area between 4 and 7 PM, some may contain gusty winds in excess of 60 mph and hail.
As the coastal storm develops off of the Carolina coast Sunday afternoon, a shield of moderate to heavy rain will push up the eastern seaboard. Rainfall may begin in earnest around noon in the southern suburbs and the steady rain should begin falling by 2PM in downtown Washington (*timing could change slightly).
Steady, soaking Rain continues through the evening across the entire Mid-Atlantic:
Monday’s highs will struggle to get out of the upper 30s and some folks in the far northern and western suburbs could even see wet snowflakes mixing in:
Precipitation Type Monday Morning: Cold rain across the Piedmont of Maryland and Virginia with heavy snow from western New York southward to the mountains of North Carolina!
European forecast model shows heavy snow accumulating from the mountains of North Carolina to extreme northern New England. ** Biggest concern will be power outages as wet snow accumulates on trees that have already bloomed…
Highs on Monday will range between 38 and 45 degrees in DC!
Wind chills will be in the upper 20s and lower 30s across the Washington Region with a gusty north wind!
Interestingly this winter featured well below normal snowfall with the biggest storms occurring in late October (heavy wet snow crippled the higher elevations of the Mid-Atlantic and much of New England) and the second mega-storm in late April. Go figure!
