625 FXUS64 KAMA 301812 AFDAMA Area Forecast Discussion National Weather Service Amarillo TX 112 PM CDT Mon Jun 30 2025 ...New KEY MESSAGES, SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... Issued at 102 AM CDT Mon Jun 30 2025 -Chances of showers and thunderstorms remain present through the holiday week with each day seeing roughly 20% to 40% chance. Any storm could produce very heavy rain leading to localized flooding. -Increasing heat toward the holiday weekend with temperatures returning to the lower 90s. && .SHORT TERM... (This evening through Tuesday night) Issued at 1254 PM CDT Mon Jun 30 2025 High pressure over the southern plains has weakened due to a progressive upper level trough now approaching the Great Lakes. Two areas of high pressure now exist, one over the Four Corners region and one (more suppressed) over east Texas, with a weakness inbetween over West Texas. This is where monsoon moisture has been on the increase, and additional moisture is expected from the remnants of Barry and the gulf region through the next few days. A stalled front is still in KS as of this writing, but many different outflow boundaries have traversed the area since yesterday evening, with the latest pushing from east to west, now crossing into NM. The airmass behind the outflow does include some modest low level moisture with dew points in the low to mid 60s in all but the southwest Texas Panhandle. Temperatures have been slow to increase through the morning with most locations still in the low 70s as of noon thanks to cloud cover. Even with the cloud cover and modest elevated instability, a few thunderstorms have managed to develop in the southeast TX Panhandle with some isentropic lift and weak upslope flow as winds continue to veer from northerly to easterly behind the outflow. There are also embedded vort maxima within the area of H5 weakness aloft, and these perturbations will continue to play a factor in storm development over the next few days as high pressure tries to build in again. The big question for today is where will the greatest coverage of storms reside, as there is great disparity in even the short term ensemble members, with some keeping the Panhandles almost entirely dry through tonight (HRRR runs), and others suggesting scattered storms will develop along and south of I-40 (RRFS runs). Based on the setup with increasing MUCAPE as H7 moisture feeds in, have retained the high PoPs for the southern Texas Panhandle, but did continue to decrease PoPs in the northern half of the area where activity should be more isolated. With PWATs on the increase (currently near 90th percentile, but increasing towards daily max values by tomorrow), and the lack of steering flow, any stronger storm could lead to localized flooding or flash flooding with rainfall rates over 2"/hr. This threat may increase in the far south this evening if some of the higher coverage model solutions pan out with some areas seeing multiple rounds of storms. The severe threat appears very low given modest instability, warm temperatures aloft, and lack of shear. Straight line winds don`t even look likely with soundings becoming more tropical-like resulting in less DCAPE (500-800 J/kg). Ward && .LONG TERM... (Wednesday through next Sunday) Issued at 1254 PM CDT Mon Jun 30 2025 Basically the short term forecast is on repeat for the next several days and what areas see the best coverage will be determined by outflow boundary positions and where the subtle waves end up each afternoon and evening. Not everyone will see storms with coverage being mostly isolated to scattered, but those that do could get an inch of rain pretty quickly, especially as PWATs peak Tuesday through Thursday. Right now, Independence Day is looking uncertain for storms with ensembles being wishy washy on the timing of a upper level disturbance and another break down of the high pressure (which may lead to increasing winds during the afternoon). Temperatures looks to stay below normal for most of the week, rising to near normal by the end of the week into the weekend. Ward && .AVIATION... (18Z TAFS) Issued at 1254 PM CDT Mon Jun 30 2025 Main concern over the next 24 hours is timing and coverage of thunderstorms. KAMA has the greatest chance of being impacted mainly between 7 PM and 2 AM, but a rogue storm can`t be ruled out for any site through the period. Otherwise, there is a 10-20% chance for MVFR/IFR cigs tomorrow morning as low level moisture increases. Some brief fog also can`t be ruled out, but chances are currently very low (<5%).
