Outlook

Showers will graze northern Utah tonight into tomorrow morning. Any rain will clear by mid morning, so the rest of Friday will be sunny but a few degrees cooler near 60. We have an up and down weekend ahead as strong southerly winds will drive in warmer air allowing highs to the soar into the mid to upper 70s. A storm system will drive a cold front into Utah Sunday morning that'll bring much different conditions: widespread rain, some thunder, accumulating snowfall in the mountains, and falling temperatures. Temperatures at midnight will be in the mid 60s, but by lunch time Sunday they'll be in the mid 50s. Timing on the arrival of precipitation is still uncertain, but best bet is mid morning to early afternoon Sunday. As colder air pools in Sunday night into Monday morning, rain and snow mix will be possible in the valleys as snow levels drop to 5000-5500 ft. Rainfall amounts in the northern valleys will be up to an inch and locally higher where lake induced showers develop Monday morning. Snowfall for the northern mountains looks generally 10-20 inches! - Devan Masciulli, KSL Weather 5.2.24
