Updated at 532 AM MDT Mon Aug 11 2025 - Continued monsoonal thunderstorms Monday through Wednesday with localized flooding, gusty winds, and blowing dust. - Much better moisture tap sets up late in the work week with flash flooding being the primary hazard. - High temperatures in the lowlands stay in the mid to upper 90s through the work week. && .DISCUSSION... Issued at 1022 PM MDT Sun Aug 10 2025 Upper high will develop over central California Monday as lingering trough energy will still be influencing us from the north and east. Perhaps a bit of diffluent flow overhead as well as a lobe energy off the high will help add extra forcing for storms tomorrow in addition to the normal forcing mechanisms (terrain influences and daytime heating). We continue to play with recycled moisture each day through midweek. Expecting PWs near to above average (generally 1"- 1.2") each of those days. Tomorrow is a little different as drier air looks to sneak in from the north which will limit storm coverage for the northern half but the southern half of the CWA will have enough moisture for decent coverage of storms as PWs may reach upwards of 1.1". CAMs are suggesting a bit of a downtick in activity compared to what we saw today which would make sense if that dry air can seep far enough south. Also, the effect of northerly flow will help bring some added shear to storms which would help with better storm organization. In addition, this dry air may actually help with hail growth tomorrow. Gusty outflow winds and blowing dust will continue to be a concern with storms as well tomorrow. By Tuesday, the trough has passed east of us and we will still be on the east side of high pressure. Moisture is near to just above average with CAPE values of around 500-1000J/kg. Storm motions look to be very slow (~5mph). Storms will be more primed to cause flooding compared to Monday. We keep near to above average moisture into Wednesday with fairly slow storm motions again (5-8mph). An incoming trough from the Pacific will arrive to western California late Wednesday. Meanwhile, high pressure over Florida will inch westward, redeveloping the monsoonal plume late in the week which will definitely return flooding issues from storms as PWs well be above average (1.2"-1.4") during this time frame. && .AVIATION... (12Z TAFS) Issued at 532 AM MDT Mon Aug 11 2025 Unsettled weather to prevail throughout the TAF period. Isold shwrs are progressing sly across the Rio Grande Valley, likely to persist over the next hour or two. Another round of aftn shwrs/tstms will take hold aft 11/20Z, with the highest coverage of tstms favoring the high terrain before pushing into the lowlands. Typical aviation hazards can be expected, including strong downburst winds, frequent lightning, and brief heavy rainfall. Lcl MVFR/IFR cigs/vsbys will be possible with any direct hits to terminals. Convectively-aided sely gusts may reach 20 to 25 kts at KELP early in the overnight period. && .FIRE WEATHER... Issued at 532 AM MDT Mon Aug 11 2025 No critical fire weather conditions are expected throughout the forecast period. Unsettled weather will persist through the week, with the highest coverage favoring the high terrain and isolated to scattered coverage in the lowlands. This will bring the typical hazards including gusty and erratic winds, lightning, and an enhanced risk of burn scar flash flooding. The ample moisture will keep minimum RH well above critical thresholds. Winds will remain relatively light outside of thunderstorm outflows. && .PRELIMINARY POINT TEMPS/POPS...
