KEY MESSAGES

* Brutally cold temperatures continue for at least the next 5-7 days. A Cold Weather Advisory will continue through today, and an Extreme Cold Warning will take effect Monday night into Tuesday with minimum wind chill values expected to reach as cold as 20 degrees below zero.

SHORT TERM /THROUGH TUESDAY/

Issued at 155 PM EST Mon Jan 26 2026

Skies have cleared out for most of the area, revealing the snow covering from the weekend winter storm. Even as the skies were clearing this morning, our temperatures were dropping a little. Wind chills look good in the Cold Weather Advisory range. With sunset though expect low temperatures to drop into the XXXX, which likely will bring those wind chills down to Extreme Cold Warning criteria for most.

An approaching mostly dry cold front will bring an increase in the winds aloft late tonight and we should see some of that mix down during the early to mid morning hours. Southerly winds will bring a brief warm up through the day...though by warm we are talking highs in the mid 20s in the northern forecast areas and around 30 for the KY/TN border region. Cannot rule out an isolated snow shower out of the associated deck of clouds coming through, but the chance for measurable snow is pretty low.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/

Issued at 155 PM EST Mon Jan 26 2026

Northwest flow will bring a second clipper system down into the region Wednesday evening. About 25 percent of ensemble members from the Euro/GFS/CMC bring at least a hundredth of an inch of QPF into the region, especially over the Bluegrass. NBM guidance was a lot less bullish with pops, so after discussing with neighbors will bump up pops a little account for some light additional snow chances.

The main story for the week will be the continued cold air in place. Highs Wed/Thu ahead of the clipper should be in the 20s for all but perhaps some of the southern IN counties. Fri/Sat we return to the teens for most, and we don't look to get back above freezing until perhaps Monday. Snowpack in place will help to keep those temperatures cold.

For the weekend, we will have to watch a mostly dry upper low dropping down from the Great Lakes. This feature may develop an Atlantic storm that we could get some fetch of moisture from Saturday night. For now will keep in the silent pops NBM gives us and watch for any westward trends on that low and the pull of moisture it could bring us.

AVIATION /00Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 657 PM EST Mon Jan 26 2026

IMPACTS:

- Period of LLWS between 07-15z - Increased gusty SW winds between 20-2kts - MVFR CIGS Tuesday afternoon

Skies will be clear with VFR flight categories for most of the forecast period. A system passing to the north over the Great Lakes will increase LLWS overnight into tomorrow morning. As this system moves in we will also see an increase in SW winds with gusts between 20-25kt.

Sfc cold front then approaches from the NW with increased clouds and lowering CIG to around MVFR levels. There is a chance with this system we could see some light snow but confidence is still low at this time so they have been left out.
