WWAs up for the rest of the LWX CWA that didn't have one earlier

This snippet was in the AFD from LWX as well this morning There are indications of CSI banding moving from south to north Friday morning, so areawide there could be brief reductions in visibilities coupled with higher snowfall rates. Given cold roads, travel could be slick/difficult Friday morning.

Georgetown isn't

NAM'D

I guess LWX is going to wait till after the 12z suite to put out WWAs for i66 corridor and north?

Slight south shift/increase in snow totals

12z UKIE 1-2 for most of the region

Close up view

12z RGEM

00z Euro is 2-4 across the region

Banned right before the biggest storm of the season... wow

For Randy - because I remember him posting this gif before a long time ago

For reference

Gimme 2-4/3-5

Better image/close up of 12z UKIE snow map

Gimme gimme

12z UKIE is nice through 72...

He was saying better than 10:1... probably more like 14:1

This is the 00z UKIE run... but it is 10:1 SR

Sure it was posted already earlier, but 00z UKIE was nice as well

Looks like 2-4 i66 corridor... 4 to 8 in MD on 12z CMC
