KEY MESSAGES

Updated at 1007 PM CDT Fri Oct 23 2026

- Afternoon RH values will drop into the 25-35% range each of the next several afternoons, creating the need for extra caution regarding open outdoor flames.

NEAR TERM

(This Evening through Saturday) Issued at 1007 PM CDT Fri Oct 23 2026

In the mid/upper-levels, the center of a subtropical high will gradually shift across the Lower Rio Grande Valley and northwest Gulf Coast through tomorrow, with an amplified ridge extending northward from the high into southern Canada. Due to this configuration, northerly flow aloft of 20-30 knots will continue across our CWFA, supporting dry conditions and clear skies overnight (with a minor increase in the coverage of cirroform clouds tomorrow). At the surface, a strengthening anticyclone (initially across southwestern QC) will build southward into the northern Mid-Atlantic states, resulting in surface pressure rises to the east of the central/southern Appalachians. As this occurs, light ESE flow overnight will veer to SSE tomorrow morning, before becoming light/variable during the afternoon hours as the local pressure gradient expands. Overnight lows will range from the l-m 40s (outlying areas) to u40s-l50s (urban locations and near large bodies of water), with brief development of patchy ground fog possible prior to sunrise in a few locations. Afternoon highs will once again reach the l-m 70s, and with dewpoints mixing down into the u30s-l40s, RH should fall into the 25-35% range.

SHORT TERM

(Saturday night through Monday night) Issued at 1007 PM CDT Fri Oct 23 2026

Over the course of the short term period, an intensifying northern stream trough will eject east-northeastward from MB into the Labrador Sea, resulting in gradual deamplification of a mid- level shortwave ridge to our west. As this occurs, northerly flow aloft will begin to subside Sunday night, before backing to WNW on Monday/Monday night (allowing for a more notable increase in the coverage of high-level clouds during this period). At the surface, we will remain under the influence of a high (initially across the northern Mid-Atlantic states) as it weakens and eventually becomes absorbed within a colder Canadian airmass that will spread eastward along the U.S.-Canadian border in the wake of the northern stream trough. A relaxed pressure gradient will support light/variable winds for much of the period, with afternoon highs remaining in the l-m 70s followed by overnight lows in the l-m 40s.

LONG TERM

(Tuesday through Friday) Issued at 1007 PM CDT Fri Oct 23 2026

The persistent ridge of high pressure across the region will still be intact early in the week. By mid week a series of mid to upper level disturbances move through the Northern Plains and Midwest, disturbing the ridge. The ridge will flatten and weaken Wednesday into Thursday, but seems to hold up enough to keep the sfc low and associated cold front north of the region. This would keep any rainfall chances out of the long term forecast. Will continue with the dry forecast through the week with a bump in cloud cover Tuesday night into Wednesday as a shortwave slides through. Otherwise, look for high temps to remain in the 70s through the week with the warmest days occurring on Thursday and Friday in the upper 70s. Overnight lows will generally be in the upper 40s with some locations reaching the lower 50s.

AVIATION

(06Z TAFS) Issued at 1202 AM CDT Sat Oct 24 2026

VFR conditions will prevail through the period, along with mostly clear skies. Calm to light winds overnight will become southeasterly and range between 5-10 knots by mid-morning on Saturday. Winds will then slacken, becoming light and variable once again by Saturday evening.
