Monday

Depending on location, light freezing rain, sleet, and or snow continues across the region at 6AM with all snow continuing to fall along the northern tier a few miles north of I 70, and a wintry mix south of there to around DC.  More of the same can be expected through the morning hours with areas along the bay and to the south the most likely to rise above freezing.  The interior areas of central MD will take a bit longer, and northern MD will probably not get to freezing today.

The second and more potent wave of precipitation will arrive early this afternoon, and there may be some surprises with its arrival.  Models show a period of moderate precipitation rates, and it wouldn’t be surprising that within those heavier rates, there is a burst of moderate snowfall across the region as the column above is cooled sufficiently at all levels. Either way, the PM rush hour today will likely be impacted in central and northern MD by either a wintry mix, and possibly moderate snow.  In areas south near DC and east along the bay, temperatures should be above freezing, but I still wouldn’t be surprised to see a period of snow in these areas later today as well.

The precipitation will continue tonight and Tuesday, and conditions will obviously be determined by what temperatures do.  For now, I think anything south of I 70 will eventually rise above freezing before Tuesday morning, while areas north of there stay below freezing.

I’ll update today, time permitting, with any specific changes.
