742 FXUS64 KMAF 080522 AFDMAF Area Forecast Discussion National Weather Service Midland/Odessa TX 1222 AM CDT Wed May 8 2024 ...New AVIATION... .UPDATE... Issued at 936 PM CDT Tue May 7 2024 Updated to expire the current Red Flag Warning and to upgrade Wednesday`s Fire Weather Watch to a Red Flag Warning. && .SHORT TERM... (This afternoon through Wednesday night) Issued at 240 PM CDT Tue May 7 2024 Quiet weather in the short term as a broad upper level low situated over northern CONUS transitions to an positively tilted trough by Thursday, maintaining dry southwesterly flow aloft over the region. A tightening gradient and downsloping westerly winds today and tomorrow indicate above-normal temperatures with breezy winds both afternoons, and highs should reach the upper 80s/low 90s with 100s along the Rio Grande. Given the gusty winds and low humidity, fire weather concerns return today and tomorrow with a Red Flag Warning in effect for today...more information can be found in the fire weather discussion below. Precipitation chances are nil for the short term with the dry northwesterly flow aloft, and overnight lows will be warm in the upper 50s to low 60s. Things start to change just beyond the short term period as a cold front associated with the aforementioned trough pushes down into the region, likely sometime on Thursday. -Zuber && .LONG TERM... (Thursday through Monday) Issued at 240 PM CDT Tue May 7 2024 Wednesday night, a secondary upper trough is forecast to develop over Nevada/Utah, leaving West Texas and Southeast New Mexico under southwest flow aloft. At the surface, a cold front will backdoor the northeast after midnight. Thursday, the front will continue pushing southwest, but today`s runs retard it a little, apparently due to diurnal heating, keeping it north of the Pecos by 00Z Friday. This will result in highs AOB normal north of the Pecos, and only a little cooler than Wednesday to the south. Thursday night, the front resumes its southwest progress after sundown w/loss of daytime heating. MOS wants to create high gap winds through KGDP, but this is a little late in the year for that. As a result of the front, highs Friday will be a paltry ~ 8-10F below normal. A few showers are possible invof the front in the lower Trans Pecos. Saturday, temperatures should be very similar to Friday`s, if not a bit cooler, despite dirty ridging over the region. The dryline is forecast to be west of the area, and shortwaves moving through the ridge are forecast to develop widespread convection across the area, making Saturday our best shot at rain this forecast. Attm, models depicts 50-60kts of deep layer shear, but steeper lapse rates look to stay west of the area on the other side of the dryline. Sunday through Tuesday, a warming trend ensues. Convection is possible Sunday afternoon, but the dryline will be farther east. Monday/Tuesday, rain chances, if any, will be confined to the northeast. By Tuesday afternoon, highs should be back to 2-4F above normal, and this could be the warmest day this forecast. && .AVIATION... (06Z TAFS) Issued at 1220 AM CDT Wed May 8 2024 VFR VIS and CIGS and west to southwest winds prevail at all terminals throughout entire TAF period. Winds increase Wednesday morning beginning 14Z-15Z and decrease in the evening starting 00Z-02Z Thursday. Winds remain above 10kts at CNM and HOB for entire period, with strongest winds at all terminals occurring from 20Z-00Z, and gusts near or above 30kts at CNM, HOB, and INK and up to 25kts elsewhere. && .FIRE WEATHER... Issued at 936 PM CDT Tue May 7 2024 Once again, an extremely dry airmass will remain across all of west Texas and southeast New Mexico Wednesday afternoon. Minimum relative humidity falls to below 10% for the entire region with elevated west winds continuing across the western half of the area. Fuels remain very dry across southeast New Mexico and west Texas south to the Presidio Valley where they have not received any rainfall recently. ERCs across these locales remain at or above the 75th percentile. RFTIs are expected to climb to critical to extreme levels across much of these same areas Wednesday afternoon through the evening and the Fire Weather Watch has been upgraded to a Red Flag Warning as a result. Near critical fire weather may return again on Thursday where it remains dry and somewhat breezy ahead of an incoming cold front but this may remain localized enough to preclude the need for fire weather products. This cold front clears the region Friday bringing better moisture. Rain chances and increased moisture continue into this weekend, ending fire weather concerns for the time being. && .PRELIMINARY POINT TEMPS/POPS...
