Salt Lake City, UT – Rain soaked roads and the possibility of thunderstorms could complicate the start of Halloween weekend as a wetter weather pattern develops across the Salt Lake City area Friday, Oct. 30. After several days of partly sunny skies and temperatures reaching the lower to middle 60s, the National Weather Service expects rain to become likely Friday, with thunderstorms also possible. Unsettled conditions could continue into Saturday, Oct. 31, bringing another round of rainfall during a weekend filled with outdoor activities and Halloween celebrations.
According to the National Weather Service in Salt Lake City, Friday is expected to be cloudy, with rain likely and possibly a thunderstorm as afternoon temperatures reach approximately 60 degrees. Rain and thunderstorms remain possible Friday night, when temperatures fall to around 44 degrees. The forecast does not provide specific rainfall totals or thunderstorm severity probabilities, leaving uncertainty about the intensity and timing of precipitation.
Rain and Thunderstorms Could Affect Halloween Weekend The approaching wet weather represents a notable change from the relatively quiet conditions expected across the Salt Lake Valley during the middle of the week. Wednesday, Oct. 28, is forecast to bring partly sunny skies and a high near 62 degrees, followed by mostly cloudy conditions and a low around 46 degrees Wednesday night.
Thursday continues the mild pattern with partly sunny skies and temperatures reaching approximately 64 degrees. However, rain chances begin increasing after midnight Thursday night, setting the stage for Friday's more widespread precipitation potential. Overnight temperatures are expected to remain near 47 degrees, keeping conditions above freezing in the city.
By Friday, residents traveling Interstate 15, Interstate 80 and Interstate 215 could encounter wet pavement and reduced visibility if periods of heavier rainfall develop. Thunderstorms could introduce additional visibility concerns, although the supplied forecast does not indicate severe thunderstorms, damaging winds or confirmed flooding threats for Salt Lake City.
Saturday brings another unsettled period, with rain likely and mostly cloudy skies expected. Afternoon temperatures are forecast to reach approximately 56 degrees, making Halloween noticeably cooler than Thursday's projected 64 degree high. The forecast does not specify when Saturday's rain will be heaviest or whether showers will continue during evening trick or treating hours.
Earlier Rain Chance Arrives Monday Night Before the late week weather change, another opportunity for precipitation arrives Monday night, Oct. 26. The National Weather Service forecasts a 50% chance of rain, mainly after midnight, with temperatures falling to approximately 43 degrees.
Monday afternoon should remain mostly sunny, with temperatures reaching 64 degrees and east southeast winds of 5 to 13 mph. The combination of mild daytime temperatures and increasing nighttime rain chances could create changing travel conditions heading into Tuesday morning.
Tuesday is expected to return to mostly sunny skies, although temperatures fall to a high near 57 degrees. Tuesday night becomes partly cloudy, with a low around 42 degrees, providing a relatively quiet transition into Wednesday's milder conditions.
What Residents Should Watch Heading Into Friday The most important forecast development is the return of rain and possible thunderstorms Friday, followed by another likely period of rainfall Saturday. Because the event remains several days away, the exact timing, coverage and intensity of precipitation could change as updated forecasts become available.
Residents planning Halloween celebrations, sporting events or weekend travel should consider indoor alternatives and monitor updated forecasts before Friday. Rainfall amounts and any localized travel impacts will become clearer as the weekend approaches.
For now, the forecast supports a wet and cooler Halloween weekend rather than a confirmed severe weather event.
