A perturbation in the upper level flow will be dropping down on the backside of this upper level trough as it departs early next week which will cause some light snow, maybe an inch or 2 on Monday, the 26th.

Here's the Evansville Merry Christmas and day after Christmas forecast from the NWS numerical computer generated guidance.
Starts 10am on 12-25-22 and goes out 48 hours. 1.3" inches of snow on Monday.
That WON'T be something that continues next week. Just the opposite. Temps will go well above average by late in the week as we hit the 50's!

WUNDERGROUND WAS CORRECT ON OUR SNOW AMOUNT < 3"
NEXT THURS. - SUNDAY ... WUNDERGROUND HAS US IN THE 50'S & 1" RAIN OVER THAT PERIOD

Latest 0z GFS and GEFS (ensemble) snow total forecast for the Monday event. Light accumulation, maybe an inch, 2 at the most:
We've been knocked off the internet for most of the past 24 hours, possibly by an attack from an entity that doesn't like my posts on the fake climate crisis or Ukraine.
Not much change in the very minor snow event of the huge warm up that follows.
The snow on the ground early in the week will be melted away at the end of the week.
Total snow accumulation from the just updated 0z GFS:
Computer generated amount from the NWS. Quite a bit more generous than most sources with 2 inches total snow.
Last 18z GFS model run:
Latest NWS info for Evansville. Maybe an inch of snow. Very light!

We got a bit MORE than 2 inches here!
Hey Mike,
It is now snowing lightly to moderately in Atlanta and nearby areas from this clipper.
Thanks Larry(who lives in the Atlanta area),
We just got to Detroit.
The drive here went from over 2 inches in Evansville to quickly tapering to near nothing an hour later. Then an area with light snow then, then no snow. Then snow covered roads, then no snow.
It was like that the entire way.
Even a surprising hour of freezing drizzle.
How the heck did freezing rain happen with a well below freezing vertical temp profile for hundreds of miles south of there and a surface temp of 23 degrees???
I've never seen this. There had to be a small pocket of warmer air aloft for some reason that was unseen by the observations/models.
Here's a new site that I found which shows snow totals for the nation going back as long as 72 hours. You can see the tiny area of 2+ inches in SW Indiana. Hover over the area with your mouse to get it.
https://www.weather.gov/crh/snowfall
The NWS 3 miles south of us reported just .9 inches of snow for the event. That seems too light. Snow depth at the time was 1 inch, including the snow from the earlier event. No way. They must be using automated instruments(its an automated station) that don't properly capture/measure snow metrics.
