A mix of rain and snow will develop across portions of the DC Region this evening. The latest HRRR (High Resolution Rapid Refresh) model shows some heavy, wet, snow developing from the northern side of the Capital Beltway northeastward into the Baltimore Metropolitan Area after the evening rush hour. Accumulations on grassy surfaces are likely, with the best chance for a higher-impact accumulating snow from northern Baltimore county eastward to Harford and Cecil counties in northeastern Maryland.
Latest future-cast radar simulation through Thursday morning (courtesy pivotal weather):
Latest Potential Snowfall Accumulation:
Washington Region: Potential for 2 to 5 inches from Baltimore city, points north and east (very tight snowfall gradient).
New York City Region:
Boston/Southern New England:
The next chance for another coastal storm comes this weekend, but it is way too soon to talk about details given the high-uncertainty in eventual track. This storm system could pass well off to our south as well as some of the latest ensembles have suggested. Forecast ability of the models this far in advance of a potential storm is highly unreliable. Bottom Line: Potential remains… something to watch.
