Salt Lake City is waking to clear skies and temperatures around 63 degrees Tuesday, but the valley is headed for another warm afternoon. The high should reach near 83, with mostly sunny skies and southeasterly winds during the morning — more late-summer behavior than early October.

The National Weather Service forecast calls for a few possible showers Tuesday, with temperatures peaking during the afternoon before sliding toward a low near 57 overnight. Wednesday looks similarly mostly sunny and warm, with another high near 83.

Warmth Holds Through Friday

Thursday should bring clear skies and a high near 83, followed by Friday’s high near 83. Overnight lows will stay mostly in the upper 50s to around 60, while winds remain light enough for comfortable mornings and easy afternoon plans.

There are no watches, warnings or advisories listed for the Salt Lake City area Tuesday. A weak system could still produce isolated showers or a few thunderstorms over higher terrain Wednesday, but the valley forecast remains overwhelmingly dry.

Weekend Brings A Sharper Turn

Saturday starts sunny, with a high near 81, while southerly winds increase and light rain is possible. Unsettled weather is possible over the weekend.

Light rain is possible Sunday, with a high near 71, then temperatures fall to around 48 Sunday night; Monday stays cooler near 64 with another chance of rain.

The updated timing is a sharper turn than Monday’s forecast, which emphasized dry warmth through most of the week. For Salt Lake City residents, Tuesday through Friday offer the best window for patios, parks and other outdoor plans before the weekend brings wind, rain and a distinctly more autumnal feel.
