DISCUSSION

Issued at 906 PM MDT Fri May 29 2026

A low pressure is currently tracking over the area, which has resulted in scattered showers and storms. These showers are mixing strong winds aloft down to the surface so gusts around 40-50 mph are possible through the evening. Tomorrow the low tracks over northern portions of the area therefore showers and storms will be expected along and north of I-70, as well as the central mountains, especially in the afternoon. These showers will be capable of producing gusty winds. The low also brings cooler temperatures so we end up 5-15 degrees below normal for highs tomorrow. Winds decrease overall, but afternoon gusts in the 20-30 mph will be common across the area. Localized elevated fire weather is possible mainly around the Four Corners region.

On Sunday there may be enough lingering moisture for afternoon showers in the northern mountains. Otherwise conditions dry out and warm up by a good 10 degrees or so. Localized elevated fire weather is possible mainly around the Four Corners region once again. Early to mid next week our area stays under southwest flow aloft and the weather remains relatively quiet. Although a weak wave approaches from the west, which may be able to draw moisture in from the south. That may be enough to support isolated to scattered showers during this period. At first glance there are no major pattern changes later in the week.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 555 PM MDT Fri May 29 2026

A line of scattered showers with embedded isolated thunderstorms extending from KSLC to KDRO are moving through the region south to north. Look for these storms to settle in along and north of I-70 after about 03Z where they will linger through the overnight hours. Showers and thunderstorms will pick up again after 18Z north of I-70 pushing west to east across the region. Main threats from these storms will be lightning and strong outflow winds gusting 40 kts or more. Otherwise, look for VFR conditions through the TAF period with areas of gusty southerly winds through the evening, becoming more light drainage winds after 06Z. Expect possible areas of Low-Level Windshear across the mountains with a strong southerly flow overnight becoming more westerly after 12Z.
