KEY MESSAGES

- Temperatures will warm through the weekend into early next week and will be accompanied by mostly dry conditions.

- A mostly dry cold front will cool temperatures on Tuesday and Wednesday with gusty westerly winds expected across northern Utah mountains and southwest Wyoming.

DISCUSSION

Mostly dry and stable conditions will persist throughout the weekend and much of next week for Utah and southwest Wyoming as a ridge near the west coast prevents any significant dips in the jet stream. The splitting trough that brought unsettled weather the past several days continues to split across the four corners bringing some gusty northerly gaps winds across lower Washington county. These winds will continue to decrease throughout the day as the splitting trough develops into a closed low off the southern California coast.

A ridge off of the west coast will nudge its way into Utah as the aforementioned trough moves out of the area. This will keep the jet stream positioned to our north and allow temperatures to warm significantly. Temperatures will warm about 10 degrees each day through Monday where they will max out in the 60s across most valley locations and low to mid 70s across far southern Utah. A weak and dry cold front will push through the region late Monday into Tuesday. Only about 24% of ensemble members have precipitation accompanying the front across the mountains of northern Utah, but totals would be <0.2" of QPF. The remaining members keep conditions dry with temperatures cooling most across northern Utah/SW Wyoming (~10 degrees) and less of a cool off the further south you go.

The cool off will be short-lived as temperatures quickly return to the 60s (across the north) and 70s (further south) by the end of the week and into the weekend with 80s in lower Washington county by the weekend. With the jet positioned to our north westerly winds will increase behind this front, particularly across the mountains of northern Utah and SW Wyoming. EFI is highlighting the potential for strong winds across southwest Wyoming Tuesday through Saturday. Current guidance keeps these winds just under advisory criteria, but this will need to be monitored in the coming days to see if wind products will be necessary.

REST OF UTAH AND SOUTHWEST WYOMING

VFR conditions are expected across all terminals through the valid TAF period. Light diurnally driven flows are expected across a majority of the area except far southwest Utah (KCDC/ KSGU) where locally stronger northerly winds will prevail through around 05-06Z. Otherwise, expect mid to high level cloud cover across the northern half of the area through around 05Z, becoming mostly clear thereafter.
