SYNOPSIS
A strong cold front will cross the region Monday, bringing a much colder airmass to the area for Tuesday.
Temperatures will quickly moderate midweek, with another period of very hot temperatures by Sunday.

.SHORT TERM (Through 12Z/6AM Wednesday)...Primary focus in the short term period of the forecast revolves around an unseasonably strong cold front that will blast across northern Utah and SW Wyoming this afternoon, central Utah this evening and southern Utah late this evening and overnight. Ahead of the front, breezy S-SW winds will increase into the 30-40 mph range, with the strongest winds along and east of Utah's mountain spine. High-res model mean suggests the cold front will enter northwest Utah around the Noon hour today, surge south across Dugway by 3PM and crossing the Wasatch Front between 2PM and 5PM. By 9PM, the front will have reached the Uinta Basin, Castle Country, and will be blasting through the Black Ridge Canyon between Cedar City and St.
George. Model consensus suggests widespread gusts in the 35-45 mph range will accompany the front, and persist behind the cold frontal passage for 1-3 hours most areas, along with an abrupt shift in wind direction to the N-NW. Wind-prone locations in such a regime such as Park Valley, the I-80 corridor between Wendover and Tooele and northern Utah Counties will have the potential to experience locally stronger winds for a longer duration. Given favorable stability profiles, we can't rule out a brief (2-6 hour)
period of gusts in the 45-55 mph range here. Timeframe for this period of locally terrain- enhanced stronger gusts is between 3PM-7PM along the I-80 corridor and Dugway, and between 4PM and 8PM across northern Utah County.

The thermal gradient across this front is truly quite impressive, with forecast 700mb temperatures at 6PM this evening ranging from minus 3C at SLC to plus 17C at Moab! Temperatures will fall rapidly behind the front. With such an extreme temperature gradient, some locations will be primed to exceed model mean gusts. We think one of those areas will be across Castle Country, where confidence is highest in Wind Advisory wind thresholds (45 mph gusts for 3 hours or more) being reached. Here, between 6PM and 3AM Tuesday morning, gusts in the 45-55 mph range are likely.
It's worth mentioning there is a low, or 10% chance for gusts as high as 70 mph near canyons of Castle Country. As a result, have issued a Wind Advisory for Castle Country to address this hazard.
Gusts will also likely top 45 mph through the Black Ridge Canyon between 9PM and the early overnight hours, but confidence is not high enough in widespread geographical extent of winds for 3 hours or more. Nonetheless, folks should be prepared for strong crosswinds on east-west routes behind the front, patchy blowing dust and isolated instances of tree and powerline damage. Expect rough chop on area waterways as well. It is recommended to secure loose, lightweight objects.

Temperatures will be cold enough behind the front to support freezing temperatures in outlying areas of the Wasatch Back Tuesday morning, including such areas as Park City and the Ogden Valley, including Eden and Liberty. For this reason, a Freeze Watch remains in effect for these areas. Across the Wasatch Front, temperatures will plunge into the 40s. Across outlying areas of the Cache Valley, temperatures may approach 32F as well, with just under a 10% chance of reaching 32F Tuesday morning in Logan.
Additionally, should enough moisture be in place, a few lake induced showers may develop downstream of the Great Salt Lake, with lake effect probabilities approaching 20% this evening.
Temperatures will be cold enough to support snow showers up the Cottonwoods, but temperatures will remain warm enough to favor rain in the Salt Lake Valley and adjacent benches.

.LONG TERM (After 12z/6AM Wednesday)...Following the much anticipated early week trough, model guidance maintains good agreement on meant troughing remaining in place to the west of the forecast area through much of the upcoming week. An upstream trough will promote increasingly warm southwesterly flow which will strongly favor temperatures warming from right around climatological normals on Wednesday to well above normal by Sunday. In fact, by Sunday the Salt Lake City area could see another shot at 100 degrees as model statistics support a 50 percent chance of exceeding 99 degrees and a nearly 40 percent chance of exceeding 100 degrees! For the St. George area, temperatures could easily rise back into the mid-100s. For both of these areas during the overnight period lows may only drop into the mid-to-upper 70s, providing very little recovery for those without proper cooling. There is generally medium to high confidence in this warm up through the second half of the week. As such, will need to evaluate heat risk for these areas over the coming days as headlines may need to be considered.

Another aspect of the forecast that will be a welcomed change is the increasing confidence in the introduction of moisture over the eastern half of Utah late in the work week. Leading up to about Friday, dry and breezy southwesterly flow will keep much of Utah with elevated, to near-critical, fire weather conditions. However, models showing increasing potential for moisture to ooze in from the Gulf of Mexico and spread across the eastern half of Utah. Most of the moisture increases are noted in the lower-to-mid levels which will help to destabilize the atmosphere and bring potential for stronger thunderstorms over the eastern half of Utah. GEFS and EPS both show precipitable water levels upwards of 190 to 250 percent of normal by Friday, respectively. This potential moisture flux could very well give us one of our first hydrologically concerning events for slot canyons, slickrock areas, and burn scars. After Friday, moisture wanes and we return to mostly dry conditions across the area... though isolated showers and thunderstorms are likely to linger across the eastern half of Utah through at least Saturday.



AVIATION
KSLC...A cold front moves across the region today, allowing for light southerly winds to switch to a northerly flow around 15Z. Gusty afternoon winds are expected over the airfield, where gusts will peak around 30-35kts. Lower level clouds will increase during late afternoon/ early evening, obscuring local topography but still remaining above VFR thresholds.

REST OF UTAH AND SOUTHWEST WYOMING
A cold front will progress across the region today, progressing from northern Utah early this morning, through the Wasatch Front through the mid-morning, and into southern Utah by the evening. Winds ahead of the front are expected to remain elevated, with gusts around 30-35kts. Behind the front, similar gust speeds are expected but out of a northerly direction.
Shower activity is expected across the northern third of Utah and southwest Wyoming, with isolated snow showers being very possible in southwest Wyoming after sundown and before midnight.

FIRE WEATHER
A strong, mainly dry cold front will cross the state Monday into Monday night. Ahead of this front, expect gusty southerly winds across southern Utah with very low humidities. The front will bring an abrupt change in wind direction to the north to northwest...remaining strong and gusty for several hours behind the front. Wind gusts in the 35-45 mph range will be common along and behind the front with locally stronger gusts. The front will cross northern Utah in the afternoon, central Utah in the evening and southern Utah from late evening trough the overnight hours Monday night. While temperatures will be considerably cooler in many locations Tuesday, humidities will not rebound much across southern Utah. Another round of critical fire weather conditions is possible Thursday into Friday across southern Utah as southwest winds increase ahead of the next system. Mid-level moisture may increase by Friday, spreading west from the Gulf of Mexico, which may bring lightning to areas that have been very dry for a considerable period of time across southern Utah. Something to watch moving forward.
