Salt Lake City, UT – A developing Pacific storm system is expected to bring widespread rain, possible thunderstorms and a sharp temperature drop to Salt Lake City beginning Thursday, October 22. Rain chances reach 100% Thursday night, with wet conditions continuing Friday before temperatures fall into the 50s for the weekend.
According to the National Weather Service forecast for Salt Lake City, showers and possibly a thunderstorm are expected Thursday night, with rainfall totals between one half and three quarters of an inch possible. The approaching storm will interrupt the city's recent warm weather and could create wet conditions for evening commuters and residents traveling across the Salt Lake Valley.

Thursday afternoon carries a 50% chance of precipitation in Salt Lake City, with thunderstorms possible mainly after noon.
Conditions become considerably wetter Thursday night as precipitation chances climb to 100%.
The National Weather Service forecasts continued showers and possibly a thunderstorm Friday, with an 80% precipitation chance. Additional rainfall amounts between one tenth and one quarter of an inch are possible Friday, with locally higher amounts during thunderstorms.
Friday night's rain chance remains elevated at 70%, particularly before midnight.
Residents in Salt Lake City and surrounding Salt Lake County communities, including West Valley City, Taylorsville and West Jordan, should monitor updated local forecasts as the storm approaches.

Extended Outlook Signals Wetter Conditions NOAA's Climate Prediction Center outlook for October 28 through November 3 favors above normal precipitation across Utah, including the Salt Lake City region.
The temperature outlook indicates near normal temperatures across much of northern Utah during that period, suggesting the extended pattern may differ from the immediate weekend cooldown.
These outlooks represent probabilities across several days and do not guarantee additional storms or specific rainfall totals.
What Residents Should Know The combination of widespread rainfall, possible thunderstorms and falling temperatures could affect outdoor plans and travel Thursday night through Friday.
Drivers should allow additional travel time during heavier showers and avoid flooded roadways if localized flooding develops.
No specific Salt Lake City flood warning is established by the supplied forecast, and the broader Four Corners excessive rainfall outlook should not be interpreted as a city specific flood warning.
