Winter Storm Threat: Feb 3 (Final Call)

Brought things northward with this update due to that pesky “warm” layer aloft. This is a considerably tough forecast across the southern areas near the 1″ line as the models generally have isothermal temperatures along the freezing line between about 850mb-750mb. Temperatures at the surface are also around freezing, with sub-freezing temperatures in most of […]

Winter Storm Threat: Dec 8-9 (Final Call)

Not much difference from yesterday’s forecast, with the 1-2″ contour extending further south around DC/MD and a bit further north in central PA. Cut back totals in the westernmost areas in WV and OH. Areas west of I-95 remain at risk for a likely amount of 0.1″+ of freezing rain after the snow falls, with […]

Winter Storm Threat: Dec 8-9 (Initial Call)

So I’m going to just ignore tonight’s snow in the northern areas in order to focus on the Sunday event, which is quite challenging with a strong CAD signal from a 1036+ mb High over PA as the precipitation starts to move in from the south and west. I expect most areas to start off […]

Winter Storm Threat: Nov 26-27 (Only/Final Call)

We have quite the complicated winter storm on our hands for tonight through tomorrow, with some snow/mixed precipitation expected on the leading edge of the system that will change over to rain in many areas before the back edge transitions over to snow. Accumulations of 1″+ are mostly reserved for the mountains where the back-end […]

Winter Storm Threat: Mar 24-25 (Final Call)

Same general theme, with a slight shift south along the southern edges and a more pronounced southern shift towards the upper part of the map. Risks are generally to the higher side on the southern fringe areas if the models are to be believed (especially if the overnight front-end thump is fairly wet).

Winter Storm Threat: Mar 24-25 (Initial Call)

The DC-Baltimore-Philly areas are expected to miss out on the more significant accumulations yet again as bothersome low-level temperatures above freezing and March climo. rear their ugly heads. One of the saving graces with this event is the onset of snow will be overnight, though this did not really help the I-95 corridor and points […]

Winter Storm Threat: Mar 5-7 (Final Call)

There were some detail changes due to adjustments in the storm track, which mostly affected central/northern PA, southern VA and the Delmarva Peninsula. Higher confidence in the higher snow totals brought some upscale changes to northern VA. It’s still a low confidence forecast overall, with both upside and downside risks across most of the impacted […]
