Later Today into Tuesday Morning

Monday, Jan 15, 11 AM

First, kudos to the NWS for putting out a special weather statement yesterday for the potential of the coating of snow that verified this morning. I was pleasantly surprised to see that the over-running moisture ahead of the system last night was able to overcome the very dry atmosphere to give us a wintry scene today. It’s been a long time that we’ve had a day where you look outside and it feels like winter. Fortunately, this is just the beginning.

For the remainder of the day, cloudy skies, cold temperatures, and the occasional light snow or snizzle will continue through the late morning and early afternoon. By 3 or 4PM, steady, light snow will develop in the metro corridor and probably cause icy conditions on some roads for any holiday commuters this evening. There may be another lull this evening, but during the overnight hours snow will redevelop and may become moderate for a few hours with accumulations expected in the 2 – 4″ range across the area. Winter Weather Advisories are posted throughout the region through tonight into early tomorrow morning.

Interestingly, as I type this, some of the midday model runs are being released and are actually an improvement for much of the area. Both the nam and gfs show an area of 4-5″ across the 95 corridor, so I’ll be curious to see if the NWS changes some of the advisories to warnings and up the totals a smidge. Regardless, the last snowfall at BWI that was at least an inch was nearly two years ago on January 28, 2022 (nearly 720 days ago!) so whatever falls over the next 18 hours we should definitely savor.

If there are any surprises or changes, I’ll update later.
