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 [...]

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

So here we are with another complicated setup and poor model agreement leading to a low confidence forecast. The good news is it looks like DC is finally going to get a decent storm! It only took until March… Anyway, right now it looks like the biggest risks are along the coast and in PA [...]

Winter Storm Threat: Nov 27 (only/final call)

This storm will drop a rain/snow mix south of the 1 inch line, with a slushy coating possible across northern MD into Philadelphia. Higher elevations will do better with this event, especially from southern PA southward. A rather weak disturbance will slide across the region tonight into tomorrow, bringing wintry precipitation to the region from [...]

Winter Storm Threat: Nov 7-8 (final call)

Made some changes to bring things a bit further east in general. I took out the 4-8 inch contour due to uncertainties in the forecast, but I do think there will be localized 4-8″ totals in eastern PA and western NJ. Confidence in the forecast is normal to slightly below normal.

Winter Storm Threat: Nov 7-8 (initial call)

Here we go with another early start to winter… but early start for who, exactly? Well, the mountains already got a shock to the system last week as Sandy dumped as much as three feet or more of snow across West Virginia. This time around, it looks like the coastal areas will cash in more [...]
