Updated at 517 PM MDT Sat Aug 29 2026 - Storm chances will be limited mostly along and west of the Continental Divide Sunday and Monday, then low chances in area mountains. - Above normal temperatures through next week, with lowland highs in the upper 90s to 100 degrees. && .DISCUSSION... Issued at 1100 AM MDT Sat Aug 29 2026 Upper high fixed over New Mexico today will continue the week- long trend of above normal temperatures. Lowland highs will again flirt with the triple-digit mark, generally in the 96-102 range. This is 5-8 degrees warmer than usual for the end of August. Not quite record setting, but still solidly above normal. Drier trend today compared to the past couple days. Upper high has flattened and become more elongated across the south-central US, cutting off moisture feed from the southeast. In response, precipitable water values have fallen to 0.9-1.0" with surface dewpoints in the mid-to-upper 40s. This slightly drier setup will greatly reduce storm chances later this afternoon. Isolated (10-30% coverage) showers will be limited mostly to higher elevations and western New Mexico this afternoon. A few gusty outflow winds may be seen, but the vast majority of the forecast area will be dry today. Upper high flattens and begins a progression eastward over the weekend. This will focus better moisture further west across eastern Arizona and western New Mexico, which will be the best chances for storms Sunday/Monday. Isolated storms along and west the Continental Divide (Grant and Hidalgo Counties for our forecast area) will be capable of gusty winds and blowing dust. Added a 4-8 PM Sunday mention of dust for Lordsburg and the I-10 corridor near the State Line due to sensitivity. Most of the Rio Grande/Tularosa basins look to be dry and warm. Weather pattern looks favorable that at least *marginal* precipitation chances will continue into early September. Upper high over the Southeastern U.S. and weak southerly flow aloft over our region would allow for moisture flow. ECMWF runs have been less bullish on moisture, keeping an elongated upper high fixed over most of the Southern US. NBM leans hard on ECMWF long term, so the extended forecast will have very low PoPs (5-10%). I do think those chances will increase as we head into next week. Expecting more isolated (hit-and-miss, mostly miss) showers and thunderstorms chances next week, instead of the dry forecast currently in place. && .AVIATION... (00Z TAFS) Issued at 517 PM MDT Sat Aug 29 2026 VFR conditions prevail through tomorrow AM. Slight chance of TS late in the period near KTCS and KDMN with confidence too low for mention in TAFs. Scattered TS develop over high terrain during afternoon and W of KDMN. KELP and KLRU should remain dry.

Rain chances expected to end quickly this evening, likely before sunset with dry conditions overnight into Sunday. Wind will be out of the south 5 to 10 mph on Saturday, leading to Fair vent rates. Winds shifting to the southwest on Sunday, with Good vent rates.ons overnight into Sunday. Storm chances will be more limited to Gila NF Sunday/Monday, as moisture focuses west of the Continental Divide. Min RH 20-30% with good overnight recoveries (60-80%) this weekend. Light south winds 5 to 10 mph today, shifting to the southwest on Sunday. Fair to Good midday vent rates. Next week looks warm with continued isolated (20-40% coverage) storm chances.
