KEY MESSAGES
- Flurries and scattered snow showers, some of which could be intense, will continue through the morning, which may cause sudden drops in visibility, slick spots or instances of black ice on roadways.
- A weak weather system could bring a mix of light snow and rain to much of the area on Wednesday.
- The winter chill wont last long. Highs will soar back into the 70s by the end of the week.
UPDATE
Issued at 801 AM EDT TUE MAR 17 2026
Updated the grids with the latest observations and data. Light flurries and scattered snow showers continue across portions of Eastern Kentucky. These snow showers may lead to minor snow accumulations of a dusting to half an inch, possibly resulting in slick spots or black ice on untreated roadways and overpasses. A stronger snow shower may briefly reduce visibility.
LONG TERM
(After midnight Wednesday night through Monday) Issued at 718 AM EDT TUE MAR 17 2026
A series of shortwave troughs will ride through a larger scale eastern CONUS upper trough as it deamplifies and shifts eastward heading into the weekend. One of these brings us a small potential for rain on Thursday, another one on Friday night, and a stronger wave with a well defined associated cold front on Sunday or Sunday night. There are run to run and model to model differences in timing and precip potential, but all agree that moisture return will be limited under NW or WNW flow aloft, and that any precip should be fairly light. Warm air advection will occur most of the time up until the arrival of the late weekend cold front, resulting in an extended warming trend, with 70s eventually expected. A sharp cool down back to normal or below normal levels is expected by Monday behind the front.
AVIATION
(For the 12Z TAFS through 12Z Wednesday morning) ISSUED AT 727 AM EDT TUE MAR 17 2026
A combination of VFR and MVFR conditions are expected through the TAF period, with isolated snow showers through this morning. These snow showers may temporarily reduce visibility into MVFR or IFR conditions. Winds will gradually increase in intensity through the late morning and early afternoon, with gusts 15-20 kts, before becoming light and variable around 00Z. Another quick moving system may result in -SHSN near 12Z Wednesday at sites KSME and KLOZ.
