Weather Will

Well another week of tracking is upon us. Wonder when NWS will change the mostly sunny forecast for the weekend....

WB 6Z EURO AI is a nice hit.

Lot of potential in the mid February to mid March period based on the latest WB EPS extended.

Mostly sleet in Brunswick, so NAM actuallly was pretty spot on about transition time but underdid QPF through 9am

Shoveled for 2 hours and can't keep up. Say 5-6 inches so far. Instant stickage. 16 degrees.

Weather Channel has me back to 14!

Looking at radar loop clearly see a SW to NE orientation with the movement of the precipitation shield. It is not lifting north like a warm front.

Great news is that at least at the surface NAM forecast is running too warm. Example: 5 am actual temp DCA was 16 degrees. NAM forecast with WB 6Z 3K NAM was 20 degrees for 5 am.

Beautiful mantel of white. Winter of 25-26 is a winner!

6Z RAP snowfall

Dusting on everything, 15 degrees.

I should clarify. WB 0Z 3K NAM has minimal snow. It is a sleet monster storm.

If the NAM busts this badly they should shut it down tomorrow.

NAM is horrible. Either NAM or NWS busts big time tomorrow.

Either NAM or NWS will bust big time tomorrow.

NAM still stinks.
