KEY MESSAGES

- Dry and mild conditions will persist areawide through a majority of the week, with the next chance for precipitation arriving this weekend.

DISCUSSION

A broad ridge over the area today will give way to a weak shortwave trough that is currently rippling through the PacNW and western Nevada. Some high clouds will continue to cross Utah ahead of it, otherwise little moisture will be available as this trough crosses Utah Tuesday morning. Main impact will be some cold advection on Tuesday under a northwesterly flow. While temperatures in the valleys will cool slightly, stronger cooling aloft should weaken the inversions in place, clearing out some of the valley haze. After the trough exits the area, a strong ridge will return to the area Tuesday night through late week.

Global deterministic models are in fairly good agreement bringing the next trough into the area for Saturday. This progressive system would bring a quick shot of widespread valley rain and mountain snow to the area. However, cluster analysis of global ensembles show a 50/50 split between this wet solution and a drier solution where the trough remains well offshore.

AVIATION

KSLC...VFR conditions will prevail at the KSLC terminal through the TAF period. Light southeasterlies will remain in place before switching to diurnally-driven northwesterlies around 18Z. Southeasterly winds will return Tuesday evening.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will prevail across all terminals throughout the TAF period with mostly clear skies and generally light and terrain driven winds.

SLC WATCHES/WARNINGS/ADVISORIES
