Sunday Snow

The first significant snow of the season wasn’t a blockbuster but it did manage to snarl traffic for a while late Sunday.

Snow reports include: Essex, 1.0″; WBAL/TV Hill, .75″; Ellicott City & Hunt Valley, .50″; BWI, .90″; Crofton, 1.5″; Owings Mills, 1.2″; Jessup, 1.4″; Laurel, 1.9″; Bowie, .60″; Frostburg, 3.0″.

The sounding balloon launched at Sterling, VA at 7pm Sunday showed that southwest winds in the lower atmosphere pushed the temperature to near the freezing point in the first few thousand feet while staying below freezing at the surface (surface winds were generally east-southeast). This is why “mixed precipitation” was included in the overnight forecast with an icing situation possible during the overnight hours.

Persistent clouds in the wake of the storm should hold temperatures below the seasonal average on Monday and precipitation chances appear minimal during the daylight hours.

The next disturbance in the pipeline should be midweek but will be riding pretty far to the north. Rain/snow chances are not all that great but a chance for a precipitation “wintry mix” was included in the extended outlook for Wednesday night. Not confident with the timing of this if it does develop. We’ll see.
