WB 18Z HRRR

WB 6Z GEFS. Don't plant annuals during the upcoming warm spell. Winter could return weekend of the 13th.

WB 12Z AI EPS and to some degree the EPS and GEFS all show trough back in the east by mid March and it continues to deepen. Worth keeping an eye on this period.

Battle of the seasons this weekend. WB 3K NAM 4pm Saturday compared to 4pm Sunday.

WB latest EPS control still likes the period around the 20th.

Heavy frost but bright sunshine.

I apologize for the mislabeling. I'll stop posting maps. You do it.

Correct fixed the label.

WB 0Z EPS has another shortwave behind Monday's storm which is kicking our threat out to sea. Not enough spacing. Too bad but right now threat for anything is greatly diminished in the DMV. No model is showing a storm here.

WB 3K 0Z NAM ticked north with some rain.

WB 0Z HRRR keeps rain to the south tomorrow.

WB 18Z EURO highlights the freezing rain, not interested.

The big storm for me last weekend was a lot of white rain. Like it or not, ground temps and sun angle matter this time of year. If the snow is a light snow during the day on Monday even with temps below freezing it will melt. Soil temps never fall below freezing on Monday. Have to factor that in.

On GFS, with warm ground from the weekend, and snow falling during the day, cut those accumulations some at least on pavement but air temp is well below freezing with 20 plus degree negative anomalies.

WB 18Z GFS: big tick south on precip compared to 12Z. On to early next week threat.

WB 12Z Can. Para snows for 24 hours. Fantastic run!

WB 12Z EURO

WB is slow as Moses....not done yet either.

WB 12Z para Canadian is a great hit! Waiting for final maps....
