Area Forecast Discussion...UPDATED National Weather Service San Angelo TX 641 PM CDT Sun Jul 11 2021 ...New AVIATION... .SHORT TERM... (This evening through Monday) Issued at 200 PM CDT Sun Jul 11 2021 A weak cold front will provide a focus for scattered thunderstorms to develop across the region through tonight. In fact, conditions may allow for hail and damaging winds to occur with any of the stronger cells that develop. In addition, many of these storms will be efficient rain producers allowing for locally heavy rainfall to occur. Otherwise, look for slightly cooler temperatures during the day tomorrow. However, you will likely not notice a huge difference as temperatures will be in the upper 80s to lower 90s. Isolated thunderstorms will remain a possibility through tomorrow afternoon. && .LONG TERM... (Monday night through next Sunday) Issued at 200 PM CDT Sun Jul 11 2021 Typical summer weather pattern for the upcoming week across West Central Texas. Enough of the upper level ridge builds into place that rain chances are minimal through most of the week, with afternoon temperatures inching up into the mid 90s for most locations. Ridge may break down a little for next weekend, enough at least to allow a weak upper trough to slide into the area. A few storms possible, especially across the western half of the area. && .AVIATION... (00Z TAFS) Issued at 640 PM CDT Sun Jul 11 2021 Areas of scattered to numerous SHRA/TSRA, bringing heavy downpours (which could result in brief LIFR/VLIFR conditions), strong downdraft winds and large hail, are possible through around 07Z north of the I-10. Then, additional SHRA/TSRA will be possible again across areas north of I-10. Otherwise, VFR conditions are expected through 00Z Tues, except for the slight chance of MVFR CIGs developing across the I-10 corridor between 08Z and 16Z, potentially impacting KSOA and KJCT. However, confidence too low to put in the TAFs. Winds will be mostly around 5-10 KT through 00Z Tues. && .PRELIMINARY POINT TEMPS/POPS...
