Area forecast discussion, Jul 25, 2:21 PM CDT, 2 hours 14 minutes before
Area Forecast Discussion National Weather Service Lubbock TX 221 PM CDT Sun Jul 25 2021 .SHORT TERM... Westerly surface winds across the South Plains early this afternoon should back to the south by 21z. Weak inhibition should erode allowing widely scattered showers/thunder to develop as advertised by CAMS taking advantage of around 1000 J/KG MLCAPE. Favored area of concentration according to the HRRR and the 12z Tech WRF run is from the Caprock Canyon/nrn Rolling Plains region, developing farther south/southwest along an axis through the central South Plains into areas S/SW of Lubbock as cap erodes around 21z (4 pm). Given weak winds aloft and fairly high PWATs (1.3 - 1.7 inches), isolated cells could produce some brief heavy rain. along with gusty winds and occasional lightning. Activity should decrease rapidly with loss of heating around 01-02z (8-9 pm), although did keep slight chance pops across the SE Panhandle overnight. Similar situation with slightly less coverage on Monday, and much less activity across the northeast where pops fall below mentionable. Temperatures/dewpoints near persistence, which are also very near climatological averages. James .LONG TERM... We'll keep a slight chance of showers and t-storms going Monday evening, as models continue to show some kind of convectively induced mesoscale vortmax sliding southwest from the Panhandles into eastern NM by evening, and this may generate enough lift despite evening stabilization to maintain any ongoing activity. Tuesday appears to be mostly dry however, with the upper high in close proximity and the mid-level moisture plume shunted farther north into the plains. Tuesday's highs should climb a few degrees area-wide with mid to upper 90s on the Caprock and upper 90s to around 103 or 104 in the Rolling Plains. By Wednesday, the center of the upper-high should be in the central plains and this should place our forecast area more squarely under easterly flow aloft. Thus we expect daytime temperatures to back off some from Tuesday's readings. In addition, a weak disturbance undercutting the ridge will bring some mid-level moisture back into the area. The ECMWF is a little weaker and farther south than the GFS with this westward-moving wave, and the forecast remains dry for now, but there is a chance that we might need to raise PoPs across the south. Beyond Wednesday, the upper-ridge looks like it will expand south and east, becoming centered roughly over north-central Okla by Friday. This should bring hot (the heat does not appear exceptional at this time) and mostly dry weather to the forecast area to close out July. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 06/33
