017 FXUS64 KSHV 110224 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 924 PM CDT Sat Aug 10 2024 ...New UPDATE... .UPDATE... Issued at 910 PM CDT Sat Aug 10 2024 Seasonably cool surface high pressure centered across the Ohio River Valley into the ArkLaMiss to bring overnight lows into the low to mid 60s tonight across these areas. Elsewhere, overnight low temperatures will average in the upper 60s to lower 70s. Convection from earlier this afternoon across portions of Oklahoma has allowed for lingering high clouds across the I-30 corridor this evening. With these areas along the northern periphery of an upper-level ridge centered across Texas, a few showers may be possible across the Red River Valley into south Arkansas and southeast Oklahoma overnight. Current forecast is on track at this time with no update necessary. /05/ && .SHORT TERM... (This evening through Sunday Night) Issued at 143 PM CDT Sat Aug 10 2024 High pressure over terrafirma is our best friend in August, unfortunately it will be modifying as quickly as it arrived. Current readings are still moreso in the upper 80s than lower 90s, but we will tap on a bit more for the highs. The 1024mb high pressure system is centered over SE MO and sprawling all down the MS River Valley. Fair skies for us with these new and improved dew points (backdoored) will remain for most of the weekend on E/NE winds. In fact, the NE winds extend into great altitudes aside from a little N/NW flow in the mid levels. So we are going a little cooler than NBM for the new day or two on lows. Once this air mass modifies a bit more, and our surface winds veer to E/SE early in the long term, both spell returning heat and humidity. So enjoy this weekend as it an exception to what is going to soon be "normal" again. /24/ && .LONG TERM... (Monday through next Friday) Issued at 143 PM CDT Sat Aug 10 2024 As mentioned the large surface air mass weakens and slides eastward as the upper ridge resumes position over midSouth. These climbing heights aloft will compress down a little extra heat, coupled with the returning humidity off the Gulf will bring back our Heat Advisory headlines early in the new work week. The storm track lingers over the top of the 594dam ridge from NM and TX across LA and the NW GoM. So just a smidge of QPF on the northern fringe for now and then a touch off the Gulf for our southern tier. It looks like the heat index may hold out on Monday for most of our Four- State area, but it will be questionable with some mention now of 105 in a few spots. That will grow to encompass our entire region by Tuesday and right on the through the extended period and beyond. So prepare to stay hydrated my friends. /24/ && .AVIATION... (00Z TAFS) Issued at 449 PM CDT Sat Aug 10 2024 Cu field across NE TX into extreme NW LA should dissipate over the next several hours but the AC and Cirrus near and northwest of the I-30 Corridor may hold on through the night. Regardless, VFR conditions will prevail overnight. Look for another cu field to develop across mainly our western half on Sunday with perhaps a little further southward progression to the high AC and Cirrus. Winds will be mostly light and variable overnight, becoming northeast across our eastern airspace and southeast across our western airspace with speeds generally under 10kts. 13 && .PRELIMINARY POINT TEMPS/POPS...
