SALT LAKE CITY, Utah – A soft drizzle dampens the Wasatch Front this morning, glistening on roads and rooftops under dim, early light. It’s the final gasp of a weak Pacific system that will exit Utah by midday Sunday, opening the door for a bright but noticeably cooler stretch ahead.

According to the National Weather Service in Salt Lake City, scattered rain showers will linger into late morning before fading west to east. Highs reach the low 60s today, then fall sharply behind the departing system. By Monday, skies turn mostly sunny but highs struggle to hit 50°F, a solid 10 degrees below seasonal averages. Breezes out of the northwest will make the afternoon feel brisk across the Salt Lake Valley and foothills.

Drivers along I-80 and I-15 should expect wet pavement and reduced visibility through early afternoon. Standing water may briefly collect in low-lying urban spots, but widespread flooding isn’t expected. Cooler, drier air arrives Monday night as lows dip near freezing—especially across Davis and Utah counties—marking the first frost risk of the season for some valley neighborhoods.

Tuesday and Wednesday bring calm, classic fall weather: crisp mornings, sunny skies, and highs in the mid-50s to low 60s. Trick-or-treat planning for Friday looks favorable so far, with dry air and light winds expected during the evening hours. Still, parents may want to layer up—Halloween night could start near 50°F and slip into the 40s before candy bags are full.

And as the weekend approaches, early model hints suggest a colder push for the start of November—perhaps the first real taste of winter for the Wasatch Front.
