NEW SHORT TERM, LONG TERM, MARINE
SHORT TERM
(This evening through Saturday night)
Issued at 218 PM CDT Fri Jul 26 2024
The area remains between an upper level high centered just east of the forecast area and an upper level height low or weakness over the Midsouth with the H5 trough extending from Mexico to the northeastern U.S. This continues to place our region well within the active southwesterly flow aloft and today it has been ACTIVE.
Numerous showers and thunderstorms have developed and several locations have gotten a few rounds of convection. PWATs are around 2.20" verified by the 12z LIX sounding. Steering is mostly light with forward propagation mostly driving the movement and in some cases across the far western areas of the CWFA, pivoting storms and backbuilding has occurred leading to a hydro threat.
Thankfully, at this juncture it would appear most of the heaviest rainfall has been over more rural areas that can take a bit more heavier rainfall than the urbanized city.
Convection will begin to decrease over the next few hours as a weak H5 impulse moves northeast away from the region along with loss of diurnal influences. That said, be mindful that given the rather weak low level flow and plenty of surface boundaries floating around from convection today, the nearshore waters and tidal lakes if any Saturday morning convection develops it may have a waterspout potential.
Speaking of Saturday, very similar to today. Temperatures held down due to the cloudiness and rainfall. Convection possible, especially the western third of the CWA closer to another weak H5 impulse over the LCH forecast area (but still close enough and times well with the diurnal cycle to spark off numerous showers and storms). And of course, hydro concerns will continue to reside across the region, especially urbanized/poor drainage areas. Also, with the widest and more robust updrafts, a strong wind gust or two will be possible, but this should mostly remain below severe limits. (Frye)
LONG TERM
(Sunday through Thursday night)
Issued at 218 PM CDT Fri Jul 26 2024
As been advertised, after over a week of the same pattern aloft, Sunday will be the transition day. The upper high just east of our region will begin to spread west across our CWFA and try to merge with the upper high over the four corners region. This will fill the weakness aloft and finally allow the large scale trough to move north and east cutting off the active southwesterly flow.
Diurnally driven showers and storms will remain possible with the higher rain chances and coverage on Sunday, however, going into the start of the new workweek, the upper level subsidence will begin to limit the coverage. This pattern takes shape and should remain through Thursday night and Friday. With the lower rain chances, temperatures will fire back up especially with the higher heights/thicknesses. Also, with the surface high mostly east, low level flow will remain southerly, which should limit mixing of low level dewpoints...meaning the heat and humidity together may require more heat headlines next week, unfortunately. (Frye)
AVIATION
(18Z TAFS)
Issued at 1233 PM CDT Fri Jul 26 2024
Convection is ongoing across local terminals this afternoon and will remain possible through sunset or so with a downward trend in coverage expected over time. Covered the scattered coverage with TEMPOs. Expect reduced VIS and ceilings in and around convection.
Otherwise, guidance do show MVFR (or lower) VIS/CIGs overnight and early Saturday for most terminals. Didn't go as low as IFR for now, but subsequent updates may require further reduced VIS/CIGs if confidence grows. Otherwise, light and variable winds expected outside of convection. (Frye)
MARINE
Issued at 218 PM CDT Fri Jul 26 2024
Favorable marine conditions will largely persist through the upcoming forecast period. Diurnally driven (mostly) convection will still be possible overnight and during the morning hours.
Slightly higher winds and seas are likely in and around convection. Otherwise, generally southerly flow expected for the offshore waters and nearshore will be rather variable depending on the diurnal surface boundaries (e.g. sea breeze or outflow boundary). Coverage of showers and storms will begin to decrease as we go later into the new workweek next week. (Frye)
