KEY MESSAGES

- Fast-moving clipper systems will move through late Tuesday and late Wednesday, with flurries and patches of light snow possible. Some localized minor accumulations could occur. - Bitter cold weather lasts through the upcoming weekend, with at least a brief warming trend then possible early next week.

- There is a low potential for a more widespread light snow event this weekend for parts of eastern Kentucky depending on the evolution of a possible large system moving up the Eastern Seaboard.

LONG TERM

(Wednesday night through Monday) Issued at 322 AM EST TUE JAN 27 2026

The forecast period begins with another clipper system tracking through the Great Lakes. The start of the period coincides with the arrival of a cold front. Snow showers are possible Wednesday afternoon, continuing through the frontal passage Wednesday night before tapering off early Thursday morning. Although the initial vertical profile is relatively dry, wet-bulbing is expected to saturate the column, resulting in flurries and isolated snow showers (0-20%). Little to no accumulation is expected with this moisture-starved system. In the wake of the departing clipper, surface high pressure will build into the region; however, northwesterly flow aloft will maintain persistent cold air advection.

While clipper activity remains confined to the northern CONUS, a surface wave is forecast to develop over western Texas as a shortwave perturbation traverses the mean flow. This feature mirrors the synoptic setup of the previous weekend, with the primary moisture source originating from the Gulf Coast. Through Thursday, this low will track across Texas, reaching the Atlantic coast by Saturday morning. Strong surface high pressure over the northern CONUS will keep the system suppressed to the south. However, as the low pivots northeast along the Atlantic Seaboard as a Noreaster, the western edge of the precipitation shield is forecast to graze the eastern half of the CWA. This will introduce another round of isolated (10-30%) snow showers from Friday night into Saturday. Subsidence and downsloping on the lee side of the higher terrain are expected to limit QPF. Nonetheless, light snow showers associated with the Noreaster remain possible through the weekend.

Behind the exiting coastal system, arctic high pressure will settle over the region, while northwesterly flow aloft sustains CAA and well below-average temperatures through the remainder of the period. The timeframe will be characterized by the passage of two distinct surface waves bringing isolated snow chances and minimal accumulations, bookended by a persistent cold pattern.

AVIATION

(For the 06Z TAFS through 06Z Tuesday night) ISSUED AT 1218 AM EST TUE JAN 27 2026

Mainly VFR conditions prevailed at TAF issuance, with only very localized MVFR ceilings still present in southeast KY. The MVFR ceilings should clear out overnight, with VFR area wide then lasting into Tuesday. Low end VFR ceilings along with flurries are expected to develop on Tuesday. Wouldn't rule out some MVFR conditions on Tuesday afternoon into Tuesday night, but the probability at any given time/location is not high enough to address in TAFs.
