Updated at 1135 AM MDT Fri Jul 17 2026 - Increased storm activity through Sunday, with a threat of heavy rainfall and localized flash flooding. - Storm chances decrease next week with drier and warmer conditions expected. && .DISCUSSION... Issued at 1135 AM MDT Fri Jul 17 2026 It was the wettest of times. It was the driest of times--a little Dickens reference to summarize the forecast. Although it won`t actually be the wettest or driest of times, it does feel a bit like A Tell of Two Forecasts. We start off wet. The CONUS is under the influence of broad ridging with the main storm track across the US-Canada border and the core of the ridge over the Northern/Central Rockies with a second core off the LA Coast. Stuck in the broad ridge, is a cut-off low, centered near the SE corner of NM. This slow-moving feature will be what gives us plenty of rain and storm chances through Monday. PW values will start off around 1.25" but will increase to the 1.3-1.4" range for much of the weekend, decreasing a little on Monday to the 1.1-1.3" range per the NBM mean. Thus daily scattered to occasionally widespread showers and thunderstorms, on and off, are expected through Monday with heavy rainfall and flash flooding the main concern. At the moment, the flash flooding threat does not appear to be widespread enough or high enough to warrant a watch. As mentioned, the UL low will make slow progress westward before making a southward shift into Mexico, with its influence exiting on Tuesday though chances will mainly be confined to areas west of the Rio Grande then. By Wednesday, POPs will all but disappear, holding on to mainly the Gila and perhaps lowlands along the AZ border through the end of the week. This is the dry part of our forecast. The UL high will push south into the Central Plains, bringing dry and hotter air with it. PW will fall closer to or below an inch per the NBM mean while highs climb above 100 for much of the lowlands. && .AVIATION... (18Z TAFS) Issued at 1135 AM MDT Fri Jul 17 2026 Mostly VFR conditions are expected with variable skies with bases as low as 100, except lower in TSRA. SCT to possibly widespread TSRA is expected this afternoon and evening with impacts likely at each terminal (>60% chance). The main uncertainty is exact timing, but TEMPO and PROB30s are included for each TAF site. Activity should wind down after dark though chances do not drop to 0. Heavy rainfall and gusty winds would be the main impact with storms. Outside of storms, winds will be light and variable. && .FIRE WEATHER... Issued at 1135 AM MDT Fri Jul 17 2026 With the exception of burn scar flooding, fire weather concerns will be minimal to none over the next few days. Abundant moisture will be in place while a slow-moving UL low approaches the area. Thus, there will be scattered to widespread showers and thunderstorms for the entire area throughout the rest of today and into the weekend, with the most likely time for rain during the afternoon and evening hours. Some areas may see as much as 2" of rainfall, especially in the mountains. With the increased moisture and below normal highs, min RH values will be in the mid 20s this afternoon and for Saturday afternoon, increasing to the mid 30s for Sunday and Monday. By Tuesday and especially the latter part of next week, we will begin a drying and warming trend. Winds over the weekend will be light, outside of thunderstorms, and venting will be fair to good through Saturday, decreasing to poor to fair on Sunday. && .PRELIMINARY POINT TEMPS/POPS...
