Issued at 1056 AM MDT Thu Jul 9 2026 High pressure over the Desert Southwest is maintaining a standard summertime pattern of very warm temperatures and isolated mainly mountain based thunderstorms in the afternoon and evenings. This pattern will persist into the weekend as the center of the high pressure area moves to the Four Corners region by Saturday. Moisture needed to fuel thunderstorm development in the region remains limited with precipitable water values hovering around an inch over the lowlands, which is the minimal amount needed to generate isolated thunderstorms with orographic lift and day time heating this afternoon and early evening. Very warm temperatures near and above 100 degrees will occur across the lowlands this afternoon and again on Friday and Saturday. Afternoon high temperatures are expected to remain just below heat advisory criteria, but it will still be very hot outside. With available moisture sitting mostly at the mid and upper levels of the atmosphere, these storms will be high based at around 8000 feet AGL, producing light spotty rainfall of a few hundredths to a few tenths of an inch. Dry and hot conditions at the surface will set up a potential for strong wind gusts and blowing dust from storms. Portions of the SW New Mexico bootheel will be especially impacted by strong outflow winds moving south from thunderstorms developing over mountains of the southern Gila Region this afternoon. There is a potential for reduced visibility from wind gusts over the Lordsburg Plays this afternoon and early evening. The weather pattern will likely repeat Friday afternoon and Saturday afternoon with isolated mainly mountain based thunderstorms producing spotty rain and strong wind gusts and possible blowing dust haboob. By Sunday the center of the dome of high pressure will have drifted north over the Northern Plains, setting up a deep easterly flow pattern over the forecast area that will allow greater amounts of moisture into the region. Projected precipitable water amounts will rise to roughly 1.3 inches Sunday night into early Tuesday. The increased moisture will support a greater number of longer lived thunderstorms that will be capable of periods of moderate to heavy rainfall near storm cores. Cooler temperatures and increased cloudiness will also result from this pattern shift. The area of high pressure will expand later next week and transport a drier air mass into the region that will limit shower and thunderstorm development later next week. && .AVIATION... (00Z TAFS) Issued at 543 PM MDT Thu Jul 9 2026 Showers and thunderstorms ongoing with several outflows out there. Sudden wind shifts and gusty winds from outflows should be expected over the next couple hours at least. This activity will start to ramp down over the next few hours with very little activity by midnight tonight. A stray shower or two is possible later tonight. Quiet and calm conditions overnight but another round of thunderstorms expected tomorrow afternoon. && .FIRE WEATHER... Issued at 1056 AM MDT Thu Jul 9 2026 We remain in a hot and somewhat dry pattern as minimum RH values in the lowland deserts drop into the teens this afternoon through Saturday. Prevailing winds will be light, generally less than 10 MPH. Enough moisture be around for scattered mountain and isolated lowland storms with gusty winds to 40 mph and isolated dry lightning the main concerns. Rain amounts will be light and spotty. Vent rates will range good to very good. This pattern changes little through Saturday, but by Sunday, moisture and Rh values will begin to increase while daytime temperatures decrease. There will be increased coverage of wetting rains and thunderstorms Sunday through early Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
