. New Short Term, Aviation .

SHORT TERM. /NEW/ /Overnight through Wednesday Night/

Broad anticyclonic flow remains in place across much of the Central U.S. in the upper levels, but a weak trough between 600-400 mb is tracking westward across the western Gulf and along the northern Gulf Coast. This feature has been responsible for widespread convection well east of our area. Cloud cover from these storms has now spread into North Texas thanks to the easterly flow and we'll likely remain mostly cloudy through the overnight hours. This may help keep lows in the lower 80s in urban areas.

On Tuesday, as the weak upper trough continues westward, a slug of 2"+ PWs will also spread west into the I-35 corridor. The atmosphere should be largely uncapped by midday with mixed layer parcels able to freely convect around 5000 ft. Weak large scale ascent and perhaps a remnant outflow boundary approaching from the east should be sufficient for widely scattered thunderstorms to develop during peak heating. High resolution guidance varies on coverage but weak wind fields and a modestly deep inverted-v profile suggests that new development will be driven by storm initiated outflow (i.e. typical hit or miss summertime thunderstorms). We'll leave PoPs areawide at 20-30% even though the radar may have a good scattering of convection during the afternoon. Storms should generally be small and slow moving. Gusty winds and locally heavy rainfall will be the main threats. Outside of any convection, temperatures will climb again into the upper 90s to near 100 with heat indices near 105. Convection will be diurnally driven and diminish during the late evening hours.

Additional scattered showers and storms will be possible on Wednesday as the trough continues westward. Best coverage of storms should shift south of I-20 as better moisture gets pushed south thanks to the expanding ridge across the Central Plains. Near or slightly above normal temperatures will continue on Wednesday with highs in the upper 90s.

LONG TERM. /Issued 323 PM CDT Mon Jul 26 2021/ /Wednesday and Beyond/

Any lingering showers or storms from late Tuesday should have all but dissipated by daybreak Wednesday. The disturbance responsible for this convection will dampen while pushing off to the west, leaving us with another warm and muggy morning. Wednesday morning low temperatures generally in the 75 to 80 degree range can be expected, the warmest of which will be in the urban "heat island" locations.

A larger scale disturbance will then move across the region in the form of an easterly wave during the mid week period. This feature will extend from Central Mexico to Central Texas, kicking off scattered showers and a few storms on Wednesday. The best rain chances will be south of Interstate 20 where chance to slight chance POPs will remain in place. The northern extent of this precip may depend on how far inland any seabreeze/outflow boundaries get Wednesday afternoon and evening. Clouds and precipitation may knock a few degrees off Wednesday high temperatures, but heat indices should still reach triple digits due to the moist airmass in place. These "apparent temperatures" may still flirt with heat advisory criteria, and we will make an assessment based on these such specifics tomorrow and tomorrow night before issuing another advisory.

Either way, high pressure aloft will return with a vengeance for the latter half of the week as 595 decameter heights at 500mb redevelop overhead. High temperatures in excess of 100 degrees will be the result, along with widespread heat indices of 105+ degrees Friday through the weekend. This summer's below normal temperatures have already come to an end, and it looks like we will round out July and enter August on a hot streak.

AVIATION. /NEW/ /6Z TAFs/

VFR will prevail through the period with SCT/BKN100 cigs overnight and light southerly flow. Better moisture and a weak disturbance will lead to scattered afternoon thunderstorms across the region. We'll include a VCTS from 21-01Z for the time being. Outside of convective areas, VFR will prevail with southeast winds around 5 kt.
