"Minor" ice and sleet back in forecast

Forecasters out at Sterling have see-sawed back and forth all week on this, so take it with a grain of road salt: They've issued a Winter Weather Advisory (blue at left) for the entire state west of I-NOAA95, calling for ice and sleet by early morning as this next storm slides along the stalled cold front to our south.

The good news is they're not very impressed with the amount of precipitation that's due, or its ability to produce a serious icing problem before temperatures warm late in the morning and it all begins to switch back to plain rain. Here's a snippet:

"I WANT TO EMPHASIZE THAT THIS IS GOING TO BE A MINOR WINTER PRECIP EVENT
WITH WINTER PRECIP POTENTIAL NOT LASTING MORE THAN 6 HRS.,"

Here's the forecast for BWI, which is east of I-95.

So sleep in 'til noon and you won't have a thing to worry about. Here's the current discussion from Sterling. And here's the advisory.

Of more interest, perhaps, is what comes in behind the rain and sleet. Cold air, and lots of it, for Monday and Tuesday. Get this:

"TO GIVE YOU AN IDEA OF THE STRENGTH OF THE COLD AIR THAT`LL BE
MOVING INTO THE AREA SUN NIGHT - AT 12Z (9 a.m.) FARGO ND WAS +23 F. AT 18Z
(3 p.m.) IT IS -1 F. THIS WILL BE PUSHING INTO THE REGION SUN NIGHT CREATING
PLUMMETING TEMPS AND A COLD NW WIND. BY MON MRNG EXPECT EVERYWHERE WEST
OF I-95 WL BE SUB 20 W/ WIND CHILLS 10 OR BELOW. 

"MON LOOKS BLUSTERY W/ HIGHS RANGING FROM THE UPPER TEENS FAR WEST TO MID 30S
E OF -I95."

Bundle up, campers.
