KEY MESSAGES

Issued at 101 AM CDT Fri Sep 18 2026

- High temperatures in the middle to upper 90s will prevail again today and continue through the weekend and into early next week, with mostly dry conditions expected throughout.

- Slight rainfall chances may impact northern and western zones early next week, but confidence is trending downwards with increasingly limited coverage.

- The very slight cooling trend has shifted later again, with highs only in the low to middle 90s late next week, and more overnight lows in the 60s.

DISCUSSION

Issued at 101 AM CDT Fri Sep 18 2026

Dry and hot conditions will persist under the broad upper level high extending from the Rio Grande Valley to the Ozarks and Middle Mississippi Valley. Another afternoon of highs in the middle to upper 90s is expected, with dew points in the low to middle 60s. Widespread triple digits are not expected, but a few sites may reach the century mark. Relative humidity values will be high enough and sustained winds low enough to not merit any fire weather headlines, but given recent dry and hot conditions, caution handling any flame would be advisable.

In a continuation of the "more of the same" pattern which has lately defined our forecast updates, the GFS depicts a weakening of the closed upper level high, opening up into a ridge and losing definition as it gets absorbed into upper level flow, leaving a closed low over the northern Gulf as the primary upper level feature early next week. Weak ridging will rebuild and eventually form a large closed high again by mid to late next week. Tonight the Euro is showing more agreement, with a smaller high, still centered over the Texas-Louisiana coast by next Thursday.

This progression is reflected in the latest PoPs trending lower still and impacting less and less of the ArkLaTex, primarily our northern and western zones Monday afternoon, if at all, with nearly negligible coverage elsewhere Tuesday. Temperature trends are thus favoring prolonged mid to upper 90s, with further delaying of the minor cooling trend, aside from lows in the upper 60s beginning to creep into our Arkansas counties by the middle of the week.

AVIATION

(06Z TAFS) Issued at 101 AM CDT Fri Sep 18 2026

For the 18/06z TAF period, mostly VFR conditions are expected to continue aside from some intermittent vsby restrictions at KLFK this morning due to patchy BR/HZ. Clouds will be limited to the daytime cu field and thin cirrus layer for much of the day. Otherwise, winds will be light to near calm overnight and increase slightly from the SE between 5-10 kts throughout the day. Beyond 19/00Z, look for SKC and near calm winds to return as high pressure continues to dominate our airspace.
