340 FXUS64 KSJT 240959 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 459 AM CDT Fri May 24 2024 ...New LONG TERM... .SHORT TERM... (Today and tonight) Issued at 354 AM CDT Fri May 24 2024 A weak cold front will drop south across the Big Country by this afternoon, with the dryline advancing into far eastern portions of the forecast area by late afternoon. CAMs continue to be anemic regarding convective development this afternoon. Despite the lack of any appreciable upper level support, isolated strong/severe storms are possible south of the front and east of the dryline during peak heating (San Saba and Mason counties). Any storms that develop will have the potential to produce large hail. Otherwise, the front should reach portions of the Concho Valley and Heartland by early evening before lifting back north tonight. Highs today will range from the upper 80s and lower 90s across the Big Country, to the upper 90s/low 100s over southern counties. Lows tonight will be mainly in the 60s. && .LONG TERM...

(Saturday through Thursday) Issued at 455 AM CDT Fri May 24 2024 Hot temperatures will prevail this Memorial Day holiday weekend. The dryline will mix east across approximately the western half of our area Saturday, and through our entire area on Sunday. Given the strength of the 850mb thermal ridging pattern and with ample sunshine, highs are expected to be mostly in the upper 90s to 105 degrees across our area. Ahead of the dryline Saturday afternoon, higher heat index values can be expected across the Heartland, Northwest Hill Country and eastern Big Country. While the possibility of a thunderstorm or two cannot be completely ruled out Saturday afternoon ahead of the dryline in our eastern counties, low confidence precludes a mentionable PoP except for the far eastern Big Country. If a storm can develop, large to very large hail and damaging winds would be possible given the forecast strong instability with 35-45 knots effective bulk shear. On Memorial day, a cold front is progged to move south across the Big Country and possibly into our central counties by late afternoon, and then across the southern half of our area Monday night. Temperatures Monday will be a little cooler across the northern third of our area with highs in the lower to mid 90s. Highs ahead of the front south will reach the upper 90s to near 105 once again. If an embedded disturbance aloft moves over the area, could have a possibility of showers and thunderstorms. At this time, think any rain chances will be to our east/southeast Monday. Temperatures should be at least a little cooler Tuesday into Thursday of next week, with increased cloud cover and chances for showers and thunderstorms. With increased moisture during that time, could have a couple of shortwave troughs move across our area. Preliminary indication is for highs to range from the mid 80s to mid 90s in our area.

&& .AVIATION... (06Z TAFS) Issued at 1247 AM CDT Fri May 24 2024 Stratus is expected to develop across the southern terminals towards daybreak and linger through the mid/late morning hours before scattering out to VFR. Haze will also be possible across the area through the morning hours, reducing visibilities to around 5SM at times. A weak cold front will move south across the KABI terminal by 18Z, shifting winds to a northerly direction for the afternoon hours. The front may make it as far south as KSJT by mid afternoon before lifting farther north tonight. Any thunderstorm development this afternoon and evening should remain east of the terminals. && .PRELIMINARY POINT TEMPS/POPS...
