.SHORT TERM...(Today through Friday)
Issued at 312 AM EST THU FEB 12 2026

Surface high pressure over the Great Lakes and Ohio Valley today
will slowly shift to the central Appalachians by Friday.
Meanwhile, northwest flow aloft will persist over our area, with
only minor waves embedded. The regime will bring continued dry
weather with only some variations in sky cover due to the
mid/upper level waves. With cold air advection easing, sunshine
will begin to bring warmer temperatures on Friday.

.LONG TERM...(Friday night through Wednesday)
Issued at 344 AM EST THU FEB 12 2026

The forecast period begins with surface high pressure anchored
beneath upper-level ridging. However, through Friday night and early
Saturday, the ridge axis will shift eastward as an upper-level
trough and associated surface low eject out of the Desert Southwest
toward the Commonwealth. Ahead of this system, Saturday will remain
dry and mild, with high temperatures reaching the mid 50s to lower
60s.

This warmth will be short-lived as the surface wave approaches by
Saturday evening. The low is forecast to track into the Ozarks while
its associated warm front lifts into the Tennessee Valley. This
synoptic setup will lead to increasing PoPs Saturday evening, with
chances ramping up overnight as the system moves through the deep
South. This track keeps the region well within the precipitation
shield. Forecast soundings during the system passage indicate high
PW values, deep-layer moisture, and a tall, skinny CAPE profile,
suggesting efficient rainfall processes. Consequently, QPF values
have trended upward by about half an inch compared to previous
forecasts. New totals are expected to range from 0.75 inches along
the Bluegrass and I-64 corridor to nearly 1.25 inches across the
Cumberland Basin and Plateau. Given these totals and recent
snowmelt, rises on local streams and rivers are likely.

Showers will persist through much of Sunday before the system exits
to the east by Monday morning. Surface high pressure will then build
back into the region, remaining the dominant feature through early
next week. By Wednesday, a passing shortwave in central Canada will
drag a cold front through the Great Lakes and into the Ohio Valley,
bringing renewed rain chances through the end of the period. Ahead
of this front, the region will reside in the warm sector with a
strengthening LLJ. LREF probabilities indicate a 50 to 60 percent
chance of wind gusts exceeding 30 mph on Wednesday.

Overall, the period remains active with multiple disturbances
expected. The first system may pose hydrologic concerns due to heavy
rainfall. After a brief cool-down on Sunday, a warming trend will
push highs into the 60s by Wednesday. Overnight lows will follow a
similar trajectory, rising from the mid 20s this weekend to the
lower 50s by Tuesday night.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
ISSUED AT 710 AM EST THU FEB 12 2026

Aside from some very localized fog, mainly in the Cumberland
basin, conditions were VFR to start the period. The fog will
dissipate this morning, and VFR should prevail from then on. Some
mid level ceilings are expected in the afternoon into the
evening.
