DISCUSSION

Issued at 207 AM CDT Sun Aug 30 2026

The center of an upper lvl ridge is progged to be cemented directly over the state of Arkansas throughout the next week before the upper lvl feature begins to slowly retrograde westward over the Southern Plains region of the CONUS and coerce northwesterly flow over the state of Arkansas into late next weekend. At the sfc, a regional area of high pressure across the Mid-Atlantic region of the CONUS will promote the presence of southerly winds overall at the surface which will meander from south-southwesterly to southerly to out of the south-southeast during the forecast period allowing dewpoint temperatures across the state in the upper 60s to mid 70s with the advection of gulf moisture by mid-week which will lead to dangerous heat index values.

Expect hot and dry conditions to be the trend over the next several days across the Natural State. Heat products will likely be needed by Monday as forecast heat index values and NWS Heat Risk both suggest environments across Arkansas supportive of Heat Advisory and Extreme Heat Warning criteria.

A glimmer of relief does appear just beyond the end of the forecast period or next Sunday going into next Monday (roughly 7-8 days from now). The upper lvl ridge slowly slides westward and positions northwesterly flow over Arkansas which will support an increase of POP chances across the state; however, confidence in this solution is low because it is a week in advance, but the signal does exist.

AVIATION

(06Z TAFS) Issued at 1201 AM CDT Mon Aug 31 2026

Expect VFR flight category across all TAF sites for the forecast period of early Monday morning through early Tuesday morning. Continued upper level ridging over Arkansas will keep hot and dry conditions in place across the state.
