DISCUSSION

Issued at 933 PM MDT Sat Aug 8 2026

The high pressure that has been centered overhead the past few days is starting to flatten out and nudge to our south. This puts us in westerly flow, which happens to be where the moisture is residing. This uptick in moisture will result in more showers and storms across the area tomorrow and following days. This initial moisture will be mainly in the midlevels leaving the lower levels rather dry still. This will make it difficult for measurable rainfall and increase the potential for gusty outflow winds upwards of 45 mph or higher. With the lack of forcing showers will develop over the high terrain before moving over the valleys. Coverage looks to gradually increase each day early next week, but the better chances appear to be mid to late week. Models are hinting at a few troughs in the region and slightly deeper mositure. With the high nudging south along with the increase in showers and clouds temperatures are expected to start cooling each day through the forecast period.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1117 PM MDT Sat Aug 8 2026

Mid and high level cloudiness will drift through over the next 24 hours leaving VFR conditions in place. There will be hazy skies due to upstream smoke and there is a small probability that MVFR conditions could occur but confidence not high attm. Afternoon shower and thunderstorm activity over the higher terrain is possible on Sunday but again chances are small enough that no introduction to TAFs will occur with this forecast.
