570 FXUS64 KEWX 021922 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 222 PM CDT Tue Jul 2 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Wednesday night) Issued at 145 PM CDT Tue Jul 2 2024 The benign weather regime featuring hot and rain free conditions under mostly clear to partly cloudy skies will continue as a mid- level ridge continues to influence the region, despite the ridge becoming gradually more centered across the Southeastern US. The afternoon high temperatures will range from the mid to upper 90s into the triple digits while overnight lows range from the mid to upper 70s to near 80 degrees near Del Rio. Highest heat indices continue each afternoon for locations along and east of the I-35 corridor with values generally between 102 and 108 degrees. A few locations in the coastal plains could briefly reach Heat Advisory levels, especially tomorrow afternoon, but areal extent should remain localized enough to where an Advisory will not be needed. Winds remain south to southeasterly across the area through the period with breezes during tomorrow afternoon picking up slightly stronger in comparison to this afternoon. && .LONG TERM... (Thursday through Tuesday) Issued at 145 PM CDT Tue Jul 2 2024 The first couple days of the long term forecast are uneventful with a flat upper ridge over the Deep South states and the western periphery of the ridge covering Texas. Over the past few days the soil and vegetation moisture was holding up the daytime dew points after the late June rains, but the current trend is for good mixing of lower dew points and near typical heat index values remaining mainly below 105. Dew points and heat indices may pick up Friday as the pattern aloft weakens and a weakening cold front comes to a grinding halt over North Central TX to draw moisture convergence with some isolated to scattered convection. Areas not seeing the convective outflows may see elevated heat index values around 105, but hopefully cloud cover will hold down the ambient temperature. The disorganized isolated to scattered convection breaks up by Saturday. By late Saturday, we may see the beginnings of impacts from powerful hurricane Beryl which is expected to cross the Yucatan Peninsula Friday. What effects we`ll see will be wide ranging until model solutions close in on a better consensus. As far as what we can expect, it will probably be at a minimum some shifty winds and perhaps some gusts. Some increasing rain chances are ramping up but slowly, as there is still a possibility for a track toward either Tampico, Mex, or Lake Charles. Thus run-to-run changes in the forecast beyond Saturday morning are encouraged to be slow until we can see what kind of interaction Beryl has with the Yucatan. Messaging in the next Situation Report will suggest some increased rain chances, but will remain mum on how much rain is possible. && .AVIATION... (18Z TAFS) Issued at 1224 PM CDT Tue Jul 2 2024 VFR flight conditions continue. The sky will consist of few to sct low to mid-level clouds and few occasional pockets of thin high level cirrus. Winds remain of light to moderate speeds out of the south to southeast. KDRT will consist of the highest gusts this afternoon up into the 20 to 25 knot range. && .PRELIMINARY POINT TEMPS/POPS...
