KEY MESSAGES

Issued at 1209 PM CDT Thu Jul 9 2026

- High humidity values combined with highs in the low to middle 90s will result in heat indices above 105 degrees for portions of northeast Texas, southeast Oklahoma, and southwest Arkansas this afternoon. A Heat Advisory will be in effect from noon through 8 PM. - Quiet and dry weather will continue through the end of the week, with areawide highs in the low to middle 90s.

- Showers and storms are expected to return this weekend, continuing through midweek.

DISCUSSION

Issued at 1209 PM CDT Thu Jul 9 2026

The ArkLaTex is sandwiched between an upper-ridge extending from southern California eastward into Texas and a weak trough across the Texas coast into north Louisiana and Mississippi. The ridge will allow for sufficient subsidence to drive temperatures into the mid 90s this afternoon across the ArkLaTex. Dewpoint values may be slow to mix across the I-30 corridor allowing for afternoon heat index values to exceed 105 degrees this afternoon. Thus a Heat Advisory is in effect from noon through 8 PM. Otherwise, the upper-trough may allow for enough instability to spark a few showers and thunderstorms across portions of north Louisiana this afternoon.

Upper-trough across the northern gulf to gradually lift north on Friday allowing for convection to develop along the seabreeze boundary with a few showers and thunderstorms possible across portions of Deep East Texas and north Louisiana.

On Saturday, the lingering upper-trough across the mid-Mississippi River valley becomes more dominant across the ArkLaTex. Instability associated with the trough combined with a northward surge of moisture from a weakness in the Gulf of America will lead to increasing rain chances areawide.

Upper-level high pressure to become firmly established across the northern plains late in the weekend into early next week bringing an easterly upper-flow pattern to the ArkLaTex. An area of low pressure is forecast to retrograde along the southern periphery of the ridge across the Ohio River Valley into Arkansas and eventually into Texas and Oklahoma by midweek allowing for an unsettled weather pattern characterized by periods of widespread rain each day. The added instability will also provide sufficient mixing to limit afternoon temperatures to the upper 80s to lower 90s. /05/

AVIATION

(18Z TAFS) Issued at 1243 PM CDT Thu Jul 9 2026

VFR conditions will continue through the 09/18Z TAF period. A scattered cu field has recently developed early this afternoon across Deep E TX and NCntrl LA, with this weak cu field spreading NE through the remainder of the afternoon. The cu should diminish by/shortly after 00Z, and aside from some thin cirrus possibly spilling into SE OK/SW AR this evening, SKC will prevail this evening through the overnight hours. Some patchy low stratus may develop by/shortly after 12Z across portions of SE and Deep E TX again Friday morning, but should quickly lift by mid-morning, with a weak cu field again developing by mid and late morning across much of the region. Isolated to widely scattered convection associated with a weak seabreeze will spread N into Deep E TX/NCntrl LA shortly after 18Z, and could affect the LFK terminal by early to mid-afternoon. SSW winds 6-9kts this afternoon will become S 4-8kts after 00Z. /15/
