Updated at 222 PM MDT Sun Aug 30 2026 - Storm chances will slowly improve early this week as upper level high pressure loosens its grip on the area. It`ll build back in again mid-week, but precip chances look a little better late in the week as upper level troughing digs in along the west coast again. - Temperatures will nudge downward this week, but remain a few degrees above normal over most of the central lowlands. && .DISCUSSION... Issued at 122 PM MDT Sun Aug 30 2026 The subtropical ridge continues to retreat towards the east, while upper-level troughing digs in along the west coast. A narrow plume of moisture aloft extends from SE Arizona into north-central New Mexico, but very dry air in the mid and upper levels remains entrenched across most of west Texas into south-central New Mexico. Low level moisture is lacking as well, and to see PWAT values much higher than the 1 inch mark, you`ll need to head west of the Arizona state line, where an overnight Gulf Surge advected in plenty of low level moisture. For us, expect widely scattered storms over the Black Range and Gila through early this evening. perhaps sneaking into the higher elevations of the NM Bootheel as well. Cluster of showers and thunderstorms in Sonora and Arizona will lift north and northeast towards the Four Corners overnight into Sunday morning, ahead of the troughing. West winds tonight and early Monday will advect some low level moisture into the lowlands from Arizona. Expect a modest uptick in thunderstorm coverage on Monday afternoon and evening as weak disturbances associated with the troughing lift into the area, and broad upper-level diffluence develops ahead of the trough. For what it`s worth, the 18Z HRRR has a more pronounced uptick in thunderstorms over the south-central lowlands Monday night, seemingly aided by a low level convergence zone that sets up along the Rio Grande. Worth watching, but it`s hard to get hopes up. Overall better moisture lurks on Tuesday, but without as much instability or lift, and then the ridge looks to build a western secondary axis back over us for Wednesday. Things look more optimistic for later in the week as west coast troughing tries to impinge on the western edge of the ridge again. Meanwhile, a weak tropical system in the Gulf looks to stay well to our east, thanks to the westward limb of the ridge. && .AVIATION... (18Z TAFS) Issued at 122 PM MDT Sun Aug 30 2026 VFR conditions expected at all terminals through the period. Could see some brief W to NW outflow winds this evening at TCS, but thunder chances are very low, as storms mostly move S to N this afternoon and evening. && .FIRE WEATHER... Issued at 122 PM MDT Sun Aug 30 2026 Upper level ridging will slowly nudge eastwards as a trough digs in over the west coast. This will send some increasing moisture out way, but with variable precipitation chances that favor southwestern New Mexico. Temperatures will ease up a bit, falling to near normal west of the Divide, and about 5 degrees above normal closer to the Rio Grande. The ridge will attempt to rebuild on Wednesday, but precip chances look better late in the week as troughing nudges in from the west again. Min RH values will around 15 percent in the lowlands, and 20 to 25 percent in the higher elevations this afternoon and again on Monday. Expect slight improvements through the week ahead. && .PRELIMINARY POINT TEMPS/POPS...
