Absolute Vorticity

12Z GFS has it getting pretty cold after a rain maker on Thanksgiving. Even a nice clipper like system to kick off December. Not bad!

I think a faster start time to the snow is the way to go. The main batch will be into Indianapolis within a few minutes.

I agree Doug, 4-5pm I would say looks good for Cincinnati.

Just perfect, I'll be driving home at that time! Hopefully, the heavier snows waits till I get home?

34 CVG only 30 at IND so things could get interesting with the air this cold. No upper 30s today lol Per INDOT Web cams, leading edge of the snow is starting to get into the Indy NW burbs now.

Based off the radar I would say before 4 pm. We will find out soon enough. Should be very nice watching the snow come down at a good clip for a couple of hours.

It was nice this morning! Can't wait for round 2. Radar looking impressive and it's been overperforming! I saw a 7" report near Milwaukee lol I have also been seeing some 2-4 amounts in Eastern Wisc. too.

While we are waiting on the snows arrival... Here is BG's SnowTalk! video from earlier.





From this morning, This Week in Weather from DT:

CVG is holding at 32. 0.09" total QPF. OH DOT cams show it's snowing I-70 / IN / ON boarder for our northern posters. SE IN posters, it is moving in also to our I-74 Indy posters.

33 with a dewpoint of 25 here. Cloudy skies. Awaiting the arrival which should happen soon.

Should be seeing flakes in Oxford, Ross, Ross Township per Web cams now. Report in folks!

Heavy snow with nice flakes getting ready to move into the West side of the Dayton Metro now per Web cams.

Flakes flying here now! Here we go!!!

Light snow and 33 at CVG officially as of 3pm.

Steadier snow is finally starting to get going here. Should look nice for a couple of hours prior to sunset.

Latest from the boys:

.NEAR TERM /THROUGH TONIGHT/...
A second vort lobe rotating around the parent low will be
pivoting through the region at the start of the near term. This
will provide the forcing needed for widespread snowfall.
Guidance suggests that the more negative values of omega
(ascent) will pivot primarily through central Indiana and past the
Tri-State before midnight. This echoes what was seen on the
mid-night shift with regards to a westward shift in highest PoP
potential. Have continued to trend higher PoPs over the Tri-
State and OH/IN border this evening into overnight.

Pavement temperatures still look to remain above freezing and
recent pavement models suggest that it will be well past
midnight before pavements fall into the 30s. With that being
said, as we saw this afternoon, any area experiencing efficient
snow rates may have some accumulation on overpasses, sidewalks/
parking lots/ elevated surfaces and grassy areas. Thinking
continues to be that an additional 1-2 inches will fall around
the Tri-State with snow tapering off after 2AM. Due to these
factors, the timing falling during a weekday rush hour commute,
and this being the first somewhat impactful snow of the
season... have continued the Winter Weather Advisory for those
southwest counties.

While daytime highs have trended a bit cooler than most guidance
suggested, the coldest 850 temps and strongest CAA have now
departed the region. Even so, have trended nighttime lows
slightly below guidance and dropped the area into the upper 20s.

Pretty also here in Greenville and as the 2nd round has moved in.

Currently 30 here.

Looking like for Thanksgiving Day with my cousin and her family from VA Beach that Bocce ball will be out so we'll make do with a movie at the cinema.

Saw a little white on cars and rooftops this morning. Even salt the city of Columbus out salting. I sure don't know why though.

31 as of 5pm at CVG with 1 mile vis. 0.10" now QPF. I am waiting on the 5pm climate report for a snow fall total at CVG. Of course more will be added this evening.

A shot out the back window before it gets dark. This morning's action all melted so this is new accum.

Steady light snow here - had a break earlier but now it has picked up once again. Temp is 31.

Wow! What a way to start the season! As of 5pm 1.1" of snowfall thus far at CVG which is a new daily snowfall record for the date. We received a months worth of snow today lol DAY 1" which is also a record for the date. CMH a trace so far today. Most areas are off to a good start!

Light snow here, temp is 31 dew of 28.

Since CVG is down to 31 degrees, today is our 3rd latest freeze on record.

It also happens that today Nov 21st is the average first day for measurable snowfall for CVG. Right on the money today.
