SHORT TERM. /NEW/ /Through Thursday/
While mid-level subsidence is keeping most of North and Central TX precip free today, a few updrafts have been able to overcome the cap and develop isolated showers across North TX. Latest radar imagery shows more of this isolated activity along/near the Red River, but coverage is expected to remain less than 20% through this evening. A few showers/storms could also sneak into our southern counties where less subsidence is present and moisture/instability is the highest. Any activity will diminish around sunset with the loss of daytime heating.
An upper level shortwave will swing by the Southern Plains tomorrow bringing sufficient lift for showers and storms to develop. However, the main limiting ingredient continues to be the amount of moisture available for better coverage of precipitation. For now, we kept 20-30% PoPs across North and Central TX in the afternoon hours. Model guidance is also showing decent instability that could support some strong wind gusts in addition to the lightning threat. Otherwise, expect highs a few degrees below normal with values in the upper 80s to low 90s.
LONG TERM. /NEW/ /Thursday Night Onward/
Despite low rain chances currently forecast through Friday afternoon, the overall pattern through the extended period will be mostly precipitation-free, humid, and seasonally hot. As North and Central Texas will be primarily under the influence of the amplified upper level ridge currently anchored over the Desert Southwest into next week, heat precautions and the potential for heat headlines will be the primary talking points this period.
By Thursday night, the showers and thunderstorms instigated by the strong shortwave traversing the region (see short-term discussion above) will gradually dissipate as the trough axis begins to pull away and daytime heating eases. Additional isolated to scattered showers and thunderstorms will be possible Friday as a slight weakness aloft will linger ahead of upper ridging building into west Texas. The best chances will generally be south of I-20. PoPs will remain capped at 20-30% as rainfall, if it materializes, will be inhibited by unremarkable available moisture and the departing shortwave. Mostly clear skies and southerly surface breezes will work in favor of the ongoing warming trend with peak daytime temperatures in the 90s and triple digit heat indices region-wide.
Late summer heat returns with a vengeance this weekend and through early next week with afternoon temperatures near seasonal normals, in the mid to upper 90s, and sufficient lingering moisture to push peak heat index values to near 105 degrees daily. Heat headlines will likely be necessary by late weekend/early next week if current trends are maintained through subsequent forecasts. While there are currently only minimal rain chances beyond Friday afternoon included in this forecast update, the potential for coastal sea breeze activity to advance into our southern zones will need to be monitored as moderate southerly breezes may allow diurnal activity to advance further inland. The good news? That breeze may keep the heat from feeling quite so oppressive.
AVIATION. /NEW/ /18Z TAFs/
Concerns . none today, convective potential Thursday afternoon.
Scattered daytime cumulus and hazy conditions will prevail the rest of the day. VFR cigs will persist through tomorrow, but we can't rule out some occasional MVFR vsby late tonight or Thursday morning. Surface winds will remain around 5-10 kt from the east/southeast shifting to the south on Thursday. Most of the convection today is expected to stay along the TX Coast, but isolated storms are possible across parts of far south Central TX and the Brazos Valley. Better convective potential is expected to arrive tomorrow afternoon. It is still to early to pin-point the exact timing, but some of the early high-res guidance show some development to the northwest and moving into the area between 22-02Z. For now, we introduced VCTS just for DFW Airport at 22Z, but we will continue to monitor the trends as new data is available.
