SYNOPSIS
An active pattern will continue through at least Tuesday. A strong cold front will cross northern Utah this evening, weakening and stalling across central Utah tonight. This front will lift north as a warm front through Saturday morning.
Another storm with valley rain and mountain snow will impact the area Saturday night into Monday morning.
.SHORT TERM (Through 12Z Saturday)...Winter is making a bit of a return through the short term forecast with a strong cold front crossing northern Utah this afternoon. Afternoon upper air and satellite analysis indicates a complex upper level pattern across the West. An upper level low is currently off the Washington Coast. A shortwave trough ejecting ahead of this upper level low is embedded in a modest speed max shifting across the Southwest.
An initial surface boundary shifted across the Wasatch Front. The main area of precipitation associated with the front is colocated with the approximate location of the 700mb baroclinic zone and is approaching the Wasatch Front as of 3 PM. Expect a period of moderate to heavy precipitation near and along this mid-level front
A few thunderstorms are also possible
and may be associated with a burst of graupel. One question that has come up a few times is what is the difference between graupel and hail? Aside from the driving atmospheric processes being different, the way to tell is graupel is relatively "squishy", while hail is hard.
Expect a quick end to the precipitation in the wake of the front this evening across northern Utah. The cold front will continue to progress into central Utah and eventually stall as the upper level support shifts to the east. This front will continue to weaken overnight.
As the upper level trough deepens offshore Friday morning, the cold front will return northward as a warm front. While precipitation will generally be light initially, a period of modest upper level diffluence may shift over the area Friday evening into Friday night and may increase the intensity/coverage of the precipitation near the warm front over northern Utah. By the end of the short term forecast period, the warm front will be near the Utah/Idaho border.
Current wind advisories are on track to expire at 6 PM. Winter weather advisories are also on track. No additional headlines are expected at this time, with the next potential to monitor will be Friday evening into Saturday morning depending on how the increased forcing combines with the warm front.
.LONG TERM (After 12Z Saturday)...A dynamic trough will keep widespread precipitation in the forecast through late Sunday/early Monday bringing mountain snow and valley rain. Once this trough exits the Great Basin late Monday/Tuesday there is unanimous agreement amongst ensemble members that a ridge builds into the area keeping us dry with increasing temperatures through the middle of the week. Our next storm is slated to move into the region some time late next week, but the timing remains uncertain amongst ensemble members.
By Saturday morning a deepening trough along the coast of California will move a warm front through the region denoted by southerly flow advecting warm and moist air through the region.
Snow levels will climb from ~6000 feet to ~7000 feet by Saturday evening with low SLR at elevation. Moisture from a landfalling atmospheric river will be advected into portions of southern and central Utah on Saturday as the California trough starts to progress east.
The heaviest precipitation looks to accompany a cold frontal passage Sunday morning. Widespread synoptic scale ascent will be in place as most of the CWA will be in the favorable left exit region of a 140+kt jet and PVA on the eastern side of the cyclonic circulation moving into the Great Basin. Snow levels look to fall to ~5000-5500 feet by Sunday afternoon behind the cold front.
Behind the front, moisture will continue to stream into the area as flow maintains a southerly component. It's not until overnight Sunday that flow starts to transition to northwesterly, in which time drier air will start to push into the area along with high SLRs. All in all, the 25th-75th percentile QPF totals across most valleys range from ~0.3- 0.8" with ~0.75-1.75" across the mountains that would translate to ~8-18" of snow.
A ridge builds into the area by Tuesday, only persisting for a couple of days before another trough moves into the area. ~52% of ensemble members bring this trough through by Thursday evening whereas the remaining 48% of members hold off until Friday evening before moving the trough through.
AVIATION
KSLC...MVFR conditions will transition to VFR as light rain tapers off around 01Z, with northwest winds transitioning to southeast. VFR conditions will continue through at least 18Z, with isolated rain showers after that.
REST OF UTAH AND SOUTHWEST WYOMING
Rain and snow will taper off from north to south for southwest Wyoming and northern Utah through the evening. MVFR conditions with rain and IFR or lower conditions with snow will continue with precipitation. Isolated to scattered rain and snow showers are likely after 18Z. Gusty southwest winds throughout southern Utah will diminish late, but enhanced southwest winds are likely from 18-00Z.
