SYNOPSIS. A low pressure system will bring cool and unsettled conditions through the remainder of the week. Drier and warmer conditions are anticipated over the weekend into early next week.
SHORT TERM (Through 12Z Saturday). A complicated pattern across the Great Basin will bring a variety of weather hazards to the forecast area over the next 12-18 hours. The key features of note are an upper low spinning over northern Nevada, with a warm frontal structure extending across far northern Utah/southwest Wyoming. A wave rotating around the base of the upper low will lift across northern Utah later this morning.
First up, easterly flow on the north side of the aforementioned warm frontal boundary has resulted in strong winds mainly north of I-80 overnight, and these winds continue to pulse at times from roughly Parleys Canyon northward to Brigham City, as well as occasionally along the east benches of the Cache Valley. However, the flow at 700mb has backed over the past couple of hours to more of a south to southeast direction, and this has resulted in a notable decrease in areal coverage of high winds, which have become more restricted to areas near Weber/Farmington and Parleys canyons over the past coupe of hours, and are likely increasingly driven by surface gradient than anything else. Have dropped headlines across southwest Wyoming as well as the Wasatch Back and Bear River/Bear Lake areas, and if winds continue to trend downward additional headlines may be dropped early as well.
Meanwhile upper diffluence downstream from the upper low continues to result in precipitation across northern Utah, and this will increase this morning as the aforementioned wave crossing central Nevada rotates across northern Utah/soutwest Wyoming. Valley rain/mountain snow with some snow down to the benches will result, and have expanded the going Winter Weather Advisory into the Wasatch south of I-80.
To the south, warm dry and windy conditions are expected in the warm sector across central and southern Utah through much of the day. Expanded the going Red Flag Warning into areas along/north of I-70 across the San Rafael Swell as hi-res guidance suggests gusty southwesterly winds spread further north into this area. Maintained the going Wind Advisory across south central and southeast zones as well.
As the upper low slowly rotates through the region tonight through Thursday, followed by a secondary wave digging in from the north Friday, unsettled conditions will persist through the remainder of the short term period. Max temperatures will run roughly 10 degrees below climo today across the north, and area-wide Thursday, before recovering a bit Friday.
LONG TERM (After 12Z Saturday). Northerly flow will remain in place into next week, as the synoptic pattern will remain largely unchanged through Utah and southwest Wyoming. A positively tilted trough to the east will slide southeast going into next week. At the same time, ridging from the west will build in.
As the trough axis slides southeast through southern Utah then into Arizona, scattered snow showers are expected through the central to southern mountains. Little or no accumulation is expected. The pattern will become more stable next week, as the trough gains momentum to the east and winds locally veer to the northwest. That will be enough to bring temperatures back to around average Sunday with dry conditions.
A shortwave ahead of the ridge is expected to move through the region Monday. EPS and GEFS members are largely dry, with a mix of those ensemble members bringing scattered valley rain and mountain snow showers. With uncertainty in a track this far out, used NBM guidance, which has a chance for rain and snow for northeast Utah. This includes the Wasatch Mountains, Bear River Range, and Uinta Mountains in Utah and Uinta County in Wyoming. Also, increased deep layer northwest flow mixing to the surface is expected. Stronger downslope winds are likely in the Castle Country region if this pattern holds. Models have bigger differences going into the middle of the week, but a better chance for precipitation is expected.
AVIATION. Downslope easterly/variable winds will taper off this morning. Northwest flow is expected to prevail by around 15Z. Rain showers are likely late in the morning into the afternoon. This could result in brief MVFR CIGs/Vsby, but VFR conditions are expected through the valid TAF period. Scattered rain showers will remain possible Thursday.
