Talk about rubbing salt on sore wounds. Over 100,000 customers in Kentucky are still without power from the last two ice storms and once more they are looking at the potential for more.

Winter Storm Warning

CORRECTED TO REMOVE START TIMING IN THE WHEN SECTION OF THE WINTER STORM SEGMENTS

...MAJOR WINTER STORM EXPECTED TODAY THROUGH EARLY TUESDAY MORNING...

.The first of two waves of wintry precipitation is moving through the region early this morning, bringing snow north of the Parkways in Kentucky, and then a mix of sleet, snow, and freezing rain south of the Bluegrass and Western Kentucky Parkways. The second, and more potent, wave will move into the region early this afternoon bring moderate to at times heavy wintry precipitation. An ice storm is expected near the Lake Cumberland vicinity, with sleet dominating the precipitation from Bowling Green to Lexington and then snow north of that line.

* WHAT...Moderate to heavy snow. Total snow accumulations of 5 to 9 inches with locally higher amounts. Some sleet is possible south of a Hartford to Elizabethtown to Shelbyville line.

* WHERE...South central Indiana and central Kentucky along and north of the Bluegrass and Western Kentucky Parkways.

* WHEN...Until 1 PM EST /noon CST/ Tuesday. The heaviest snowfall is expected this afternoon and evening.

* IMPACTS...Travel could be very difficult to impossible...especially when snowfall rates come faster than treatment methods can handle.

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

Difficult forecast to make today, we will have to wait to see exactly where the rain/sleet/snow line sets up across the state. I know it's a bit disheartening to see the same areas hit by the previous ice storm starting to fall in line for another one. Ice is still in on trees and powerlines at this time, so it won't take much to bring them down once more. The farther Northwest you are the more likely you will see accumulating snow fall of 8-12 inches. 

You can see from the HRRR model where it is thinking this line sets up. Freezing rain/ ice to the East in the pink, sleet mix in purple, and all snow in blue. If you are in Eastern Kentucky, be prepared once more for power outages and dangerous driving conditions.

Ice Storm Warning

MAJOR WINTER STORM TO IMPACT CENTRAL KENTUCKY...

.Significant ice accumulations are expected across much of central Kentucky today and tonight, and then expanding into south central Kentucky tonight and Thursday. To the north of the Parkways, a mixture of freezing rain, sleet and snow is expected.

There still remains a bit of uncertainty on the northward extent of the most significant icing. Changes to the current warning and advisory structure may be required in future forecast updates.

* WHAT...Significant icing expected. Widespread ice accumulations of a quarter to half inch, with localized amounts up to three quarters of an inch. Isolated higher amounts are possible. The heaviest ice accumulation is expected to occur south of the Western Kentucky and Bluegrass Parkways.

* WHERE...Much of central Kentucky.

* WHEN...Today and tonight near the Western Kentucky and Bluegrass Parkways, expanding into south central Kentucky tonight and Thursday.

* IMPACTS...Significant power outages and tree damage are expected due to the ice. Travel could be nearly impossible at times.

Travel is strongly discouraged. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. Prepare for possible power outages. If you must use a generator for emergency power, make sure that you run the generator outside of your home...not inside your home.

   Areas affected...Lower Ohio River Valley

   Concerning...Freezing rain 

   Valid 101718Z - 102115Z

   SUMMARY...Freezing rain is expected to expand in coverage and
   intensity across portions of the Ohio river valley this afternoon.
   Freezing rain rates approaching 0.05 to 0.1 inches per hour will be
   possible.

   DISCUSSION...12z upper-air observations showed broad cyclonic flow
   across the northern 3rd of the CONUS with several small shortwave
   troughs embedded within this flow. Over the last 2 hours, radar data
   shows stratiform precipitation across portions of southern Illinois
   and eastern Missouri increasing in coverage/intensity likely due to
   increased isentropic and large scale ascent from one of the
   approaching shortwave troughs. Surface observations under the
   developing band of precipitation indicate freezing rain/ mist as the
   primary precipitation type across the area.

   Hi-res model guidance and observational data suggest that rain rates
   will gradually increase through the afternoon as isentropic ascent
   continues to strengthen along and north of the surface front. A few
   thunderstorms my also develop across the region with guidance
   indicating MUCAPE around 100-150 J/kg aloft. Rates may approach 0.1
   in/hr in the heaviest cores through this afternoon. Additional
   precipitation will likely expand southwestward as greater forcing
   for ascent develops aloft. Freezing rain and occasional sleet appear
   to be the most likely precipitation types through the next several
   hours given upstream and downstream RAOBS showing fairly uniform
   +1-2 C warm layers atop sub freezing surface layers.
