KEY MESSAGES

- Showers and storms will decrease in coverage and intensity over the next few days as drier air moves in.

- Hot and predominately dry conditions move in for the weekend and beyond.

DISCUSSION

Issued at 1042 PM MDT Wed Jul 29 2026

After the last several days, dry air finally starts moving in but it'll take a day or two for residual moisture to completely leave the area. That means we'll see some convection but it shouldn't be as widespread or as strong as what we've seen recently. As the drier air moves in, concerns will shift from heavy rain to gusty outflow winds, possibly reaching 50 mph at times.

High pressure then starts to build in over Utah for the weekend bringing hot and mostly dry conditions to the region. Temperatures will remain hot, reaching about 10 degrees above normal, but with less moisture it'll feel less muggy and more of a 'dry heat'.

AVIATION /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 1145 PM MDT Wed Jul 29 2026

Some scattered shower activity will continue this morning over the mountains west of the Divide, mostly north of I-70. Breakpoint conditions are not expected, but a few gusty outflow winds could impact airfields, along with lightning and brief rain showers. VFR conditions will be dominant across eastern UT and western CO on Thursday. Some isolated showers and thunderstorms are still expected in the afternoon on the mountains. Confidence in coverage is pretty low at this point, but valley airfields will likely face some gusty outflow winds and brief downpours at some point Thursday afternoon as these storms decay. Drier conditions set in later Thursday and VFR conditions will close out this TAF period.
