Rain and cold are forecast for northern Utah during Halloween week

A cold spell is expected to arrive in northern Utah overnight Monday into Tuesday, with a high chance of rain and low temperatures near freezing.

The National Weather Service forecast also calls for cold temperatures and a slight chance of rain Thursday night, which could deter Halloween trick-or-treaters.

A cold front is expected to cross the Wasatch Front Monday afternoon and Tuesday morning, bringing colder temperatures to the area, with a 20% chance of rain after noon Monday and an 80% chance of rain Monday evening and Tuesday morning.

The lowest temperatures on Monday night and Tuesday morning are expected to reach 36 degrees, the weather service forecast said.

Some areas along the Wasatch Front may see some snow early Tuesday morning, changing to rain after 9 a.m. Tuesday's high temperature is expected to be around 45 – nearly 20 degrees colder than Monday's high temperature.

Snowfall is possible in mountain areas and the Wasatch Back on Tuesday and Wednesday.

The forecast says the cold will continue for a few days, with a 20% chance of rain early Wednesday and a slight chance of rain Thursday evening (Halloween) and Friday morning.

The weather service forecasts highs of 49 for Wednesday and 53 for Thursday. Low temperatures will drop to 33°C on Tuesday and Wednesday evenings, dropping to 37°C on Halloween night.

The forecast says winds will increase Thursday evening, “but nothing headline-worthy.”

Highs are forecast to remain in the low 50s through the weekend, with lows in the mid 30s.

Weekly temperatures will be 10 to 20 degrees cooler than usual in the last week of October, the weather service said.
