KEY MESSAGES
- Mostly dry with above normal temperatures Monday before a cool down to near normal Tuesday and Wednesday, and then returning to above normal temperatures the remainder of the week and weekend.
- Strong and gusty westerly winds will develop on Monday and persist through the weekend across southwest Wyoming and along the ridgetops and leeward side of terrain of central and northern Utah.
DISCUSSION
High pressure will start to flatten on Monday as the jet to our north sags further south and approaches northern Utah. Temperatures on Monday will remain unseasonably warm with highs ~10 degrees above normal for this time of year. Southwesterly winds will increase, particularly across southwestern Utah, ahead of a weak cold front that will push through Monday night. Winds will remain below advisory levels, though.
The front that will move through will likely be dry as only ~40% of EC ensembles (no GEFS or CAN members) have very light precipitation across northern Utah. With the jet stream remaining just to our north and east, a tightening pressure gradient will induce strong westerly/northwesterly winds across southwest Wyoming and along/east of the terrain of northern and portions of central Utah for much of the week and into the weekend. EFI is highlighting southwest Wyoming Thursday-Saturday as the time for strongest winds. However, the magnitudes of these wind gusts is likely (95% chance) to remain below 58 mph.
Temperatures will increase again by midweek with highs ~10 degrees above normal across the north and 15-20 degrees above normal across southern Utah. As the jet stream stays in this zonal flow pattern to our north there will be opportunities for it to bring some moisture into the northern portion of the CWA by later into the weekend. 61% of ensemble members bring light precipitation into northern Utah/SW Wyoming by Sunday.
REST OF UTAH AND SOUTHWEST WYOMING
VFR conditions will prevail through the TAF period across all terminals of Utah and southwest Wyoming. Diurnally driven flows are expected across a majority of the area; however, gusty west to southwest winds with peak gusts around 25-30kts will prevail in southwest Wyoming for Monday afternoon.
