Winter Storm Threat: Jan 31 – Feb 2 UPDATE

I made some changes in the Wednesday forecast to account for warmer surface temperatures… not too much of a shift, but it could change the plans for a significant amount of Maryland workers.   We’re still looking at 0.1-0.2″ of freezing rain along the northern parts of the rain area before it switches over around […]

Winter Storm Threat: Jan 31 – Feb 2

The strength of the cold air damming will be a big player in determining where the different areas set up. Based on recent guidance and trends, I’ve come up with the following maps depicting the first event (with light precip. totals over most of the region) and for the second event (which will have QPF […]

Clipper system a bit better than expected

Areas in northern VA, MD, DC and Delmarva could see 1-2″ of light snow today as a clipper system moves over the region. I was thinking 0.5-1″ earlier, but with the radar filling in and areas of moderate snow forming, higher amounts are expected, with some areas possibly even going over 2″. The band setting […]

Heavy snow, sleet and thunderstorms innundate the region

As heavy snow (+SN) is falling outside my window, I can only imagine how crazy it is for anyone to be out at this time. I-95 city rush hours from DC to NYC are getting rocked by this storm, as seen on the map below (from 4:45pm EST): (click for full res.) It’s starting to […]

Snow Threat: Jan 26-27 (final call)

My idea of a higher snowfall band has come to fruition on the models, though not at quite the angle (or with the somewhat lower snow amounts) that I expected. After some considerable brain-wracking, this is what I’ve come up with:   The map calls for a somewhat more northerly solution than what is currently […]

Snow Threat: Jan 26-27 (first call)

Before I begin, I’d like to state that this forecast has fairly low confidence as we sit in the 3-4 day window with the coming coastal storm. There is still a lot of room for changes to the storm track and snow totals, so this forecast is to be taken with a grain of salt. […]

Snow Threat: Jan 20-21 (final call)

Final map… probably 90% the same, with some tweaks to the snowfall gradient in West Virginia, extent of 4-8″ in the west, small adjustment north in northern Virginia and small adjustment south along the coast. Added a HHMM timestamp (GMT/UTC time) on the issuance time because it seemed warranted. Hopefully this is the final version […]
