NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 15, 4:47 AM CST, 6 hours 13 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Fort Worth TX 547 AM CDT Fri Aug 15 2025 ...New Aviation... .KEY MESSAGES... - A Heat Advisory remains in effect for most of North Texas and East Texas through this evening. - Hot and humid conditions along with daily low storm chances can be expected through early next week. && .SHORT TERM... /Issued 210 AM CDT Fri Aug 15 2025/ /Today and Tonight/ A warm and humid night is unfolding across North and Central Texas as southerly flow persists beneath the building ridge aloft. Overnight lows will remain elevated, generally in the mid to upper 70s with parts of the Metroplex likely hovering closer to 80 degrees through sunrise. The upper level ridge will become more influential over the region today, resulting in another hot and somewhat humid day with highs in the upper 90s to near 100 degrees. Though dewpoints across our northwest counties should mix into the upper 60s this afternoon, ambient temperatures nearing 100 degrees will still push peak heat index values as high as 106 degrees. As a result, the Heat Advisory has been expanded to include Montague, Wise, Young, Jack, and Parker counties. The rest of the advisory area remains unchanged, with the great coverage of 105+ degree heat index values expected east of I-35. The more subsident environment will keep precipitation chances low, with only a slight (10-20%) chance for isolated showers and storms in our far southeastern counties, where weak sea breeze activity may reach before dissipating. Friday night will be warm and muggy again with lows in the mid 70s. By Saturday, the ridge axis is expected to shift east toward the Mississippi Valley, opening the door for a modest uptick in rain chances across Central and East Texas, especially during peak heating. Coverage will remain scattered at best, with most areas likely remaining dry. There is also the potential for parts of the current advisory area, particularly east of the I-35 corridor, to meet Heat Advisory criteria again on Saturday. Despite expected afternoon mixing, dewpoints are forecast to remain in the mid 70s with highs in the mid 90s, which would yield peak heat index values near or above 105 degrees. A final decision on any extension of the current advisory will be made later today. 12 && .LONG TERM... /Issued 210 AM CDT Fri Aug 15 2025/ /This Weekend through Next Week/ The axis of the upper ridge will remain displaced to our east through Sunday while a weak shortwave embedded within the broader ridge rotates into North Texas. This pattern will spread low (10-20%) rain chances across the region late weekend into early next week, though coverage should remain modest. As the ridge retrogrades toward the Desert Southwest by midweek, weak northerly flow aloft will return over the Southern Plains. This may allow one or more convective complexes from the Central Plains to drift into North Texas during the midweek period, but confidence in timing and placement remains low at this range. 12 && .AVIATION... /NEW/ /12Z TAFs/ VFR conditions are expected to persist through the period with a prevailing south wind around 6-10 kts this morning increasing to 10-14 kt by this afternoon with occasional gusts to near 20 kt possible. MVFR cigs have been slow to develop across Central Texas this morning, currently stretching from near SAT up towards AUS. The probability of this isolated stratus reaching KACT over the next several hours has fallen to around 20%. This afternoon, a few diurnally driven showers or storms may develop across Southeast Texas, but should not impact the TAF sites. 12 && .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time. && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
