A cold spell is expected to arrive in northern Utah on Monday night into Tuesday — bringing a good chance of rain and low temperatures near the freezing point.

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

A cold front is expected to cross the Wasatch Front on 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 night and Tuesday morning.

The low temperature on Monday night and Tuesday morning should reach 36 degrees, the weather service’s forecast said.

Some areas along the Wasatch Front may see a bit of snow early Tuesday morning, changing to rain after 9 a.m. Tuesday’s high temperature is expected to be near 45 — nearly 20 degrees colder than Monday’s high.

Mountain areas, and the Wasatch Back, may see snow Tuesday and Wednesday.

The chill will last a couple of days, according to the forecast, with a 20% chance of rain early Wednesday and a slight chance of rain Thursday night — Halloween — and Friday morning.

The weather service predicts highs of 49 on Wednesday and 53 on Thursday. Low temperatures will drop to 33 on Tuesday and Wednesday nights, 37 on Halloween night.

The forecast says winds will pick up Thursday night, “but nothing worthy of headlines.”

Highs will stay in the low 50s through the weekend, the forecast says, with lows in the mid-30s.

Temperatures for the week will be 10 to 20 degrees cooler than usual for the last week of October, the weather service said.
