High pressure will generate a warming trend across most of the state as the work week begins, but a midweek snowstorm will cool things down and affect early holiday travel.
According to the National Weather Service, skies Monday and Tuesday will be partly cloudy in the northern half of the state, and mostly sunny in the south. Urban haze is expected to increase, but not to the degree it accumulated last week.
On Wednesday afternoon through Thursday, a strong cold front will follow the windy, warm conditions, the NWS says. Snow is expected to accumulate, which will have “significant travel impacts for early holiday travel in the mountains and across western [and] northern Utah.”
Air quality is expected to be in the moderate, yellow category for almost the entire state Monday, with Washington County as the sole exception. Air there will be good, in the green category, according to the Utah Division of Air Quality. Those air quality levels are expected to remain steady Tuesday and Wednesday.
Highs in the Salt Lake and Tooele valleys will reach about 40 degrees Monday with partly sunny skies turning partly cloudy as the day wears on. Overnight temperatures will drop into the upper 20s before climbing into the mid-40s Tuesday. Temperatures will be similar Wednesday before the cold front moves in.
Residents in the St. George area can expect sunny skies with highs in the mid-50s Monday with lows dropping to about 30 degrees overnight. On Tuesday, highs will reach about 60 degrees with lows dropping into the lower 30s overnight. Wednesday will be partly cloudy with highs about 60 before southwest winds move in, bringing a slight chance of rain showers in the evening and rain and snow showers after midnight.
The risk for avalanches is low in areas near Logan, Ogden, Salt Lake, Provo and the Uintas, the Utah Avalanche Center says.
