KEY MESSAGES

- High pressure will bring warming temperatures and dry conditions through Monday.

- A mostly dry cold front will knock temperatures back to near normal on Tuesday and Wednesday, with gusty westerly winds expected across northern Utah mountains and southwest Wyoming.

- Temperatures will climb 10 to 15 degrees above normal Thursday into Friday.

DISCUSSION

Mid level ridging building into the Great Basin this evening will allow for a considerable warming trend over the next 48 hours. Max temperatures will trend roughly 10 degrees warmer across the forecast area Sunday, then climb another 6-8 degrees Monday, ahead of an approaching cold front. The current forecast high of 66 for KSLC Monday would be the warmest daytime temperature since 67 was recorded on December 22nd (??!!).

A relatively shallow and generally dry cold front will push through the forecast area Tuesday, knocking daytime temperatures back to near climo for Tuesday and Wednesday. This is in response to a shortwave trough and associated upper jet passing just north of the area. The core of the upper jet and 500mb cold pool remain north of the Idaho border, resulting in a fairly stable airmass along/behind the frontal boundary. That said, there is a 20% chance the higher terrain squeezes out a few hundredths of QPF as this boundary passes. Additionally, post-frontal westerly wind gusts will approach 45 mph across Uinta County WY Tuesday afternoon and evening

This cool-down will be short-lived as temperatures quickly rebound into 60s across northern Utah by Thursday, and 70s across southern Utah valleys (80s in lower Washington County). Longer range guidance suggests the potential for another grazing shortwave bringing another cooling trend next weekend.

REST OF UTAH AND SOUTHWEST WYOMING

VFR conditions will prevail through the TAF period. Expect diurnal wind shifts across each terminal through the day tomorrow.
