Outlook

Scattered thunderstorms capable of producing flash flooding will be possible across the south-central and southeastern Utah through tonight. Isolated thunderstorms will be possible Saturday afternoon across eastern Utah if they develop over the mountains and drift off. For the majority of us, we'll have a mix of thin clouds and sun. Winds will be breezy, especially across western Utah. Winds will be strongest on Sunday as a could from slides across the state, northwest to southeast. This will knock temperatures down several degrees across northern Utah from the low 90s Saturday to mid 80s Sunday. The coolest air settles in Monday as lows drop into the mid 50s and highs drop into the mid 70s. - Devan Masciulli, KSL Weather 9.11.26
