Sounds like they are going to up the accumulations with the 3:00pm package.

Don't get too excited, it sounded like 0.5-1.0" is how much they are going up.

One thing I noticed and maybe the reason for the higher totals that models are starting to throw out is in southeast Missouri and northeast Arkansas looks like a low is trying to get itself together. I know Brian talked about how hard that is with the fast and strong jet. The precip in southern Missouri has been stubborn and not moving to much to the east over the last few hours and this would make sense if a low is trying to get itself established. Will continue to monitor that area

The one thing you notice is with the recent sref totals are going up from Paducah through Louisville into the Cincy/Day area. They have not gone up much in Indy or towards Lexington. To me this would indicate a low moving out of northeast Arkansas and heading towards eastern Kentucky. Again this is just trying to put the two together and may be happening.

...WINTER STORM WARNING IN EFFECT FROM 7 PM THIS EVENING TO 5 PM
EST FRIDAY...
...WIND CHILL WARNING REMAINS IN EFFECT FROM 1 AM TO 5 PM EST
FRIDAY...

* WHAT...For the Winter Storm Warning, combination of snow,
blowing snow, and wind expected. Total snow accumulations of 1
to 3 inches. Winds gusting as high as 50 mph. For the Wind Chill
Warning, dangerously cold wind chills expected. Wind chills as
low as 35 below zero.

* WHERE...Portions of Northern Kentucky and South Central and
Southwest Ohio.

* WHEN...For the Winter Storm Warning, from 7 PM this evening to
5 PM EST Friday. For the Wind Chill Warning, from 1 AM to 5 PM
EST Friday.

* IMPACTS...Plan on slippery road conditions. Patchy blowing
snow could significantly reduce visibility. The hazardous
conditions could impact the morning or evening commute. The
cold wind chills could cause frostbite on exposed skin in as
little as 30 minutes.

* ADDITIONAL DETAILS...Temperatures will drop sharply in the
matter of a few hours during Thursday night, rapidly falling
well below freezing, leading to the potential for a flash
freeze. This will cause travel conditions to rapidly
deteriorate.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you must travel, keep an extra flashlight, food, and water in
your vehicle in case of an emergency.

Avoid outside activities if possible. When outside, make sure you
wear appropriate clothing, a hat, and gloves.

Would not surprise if spreads even further south and east as the evening goes to replace the winter weather advisory. Update and again things are changing fast but the western half of Kentucky is under the winter storm warning
