A Pacific storm system will move into the Fresno area on Tuesday, bringing with it cooler temperatures, chance of rain and snow to the mountains, according to the National Weather Service.
Senior meteorologist Jeffrey Barlow said the weather for trick-or-treaters will be seasonally mild, with temperatures in the low 70s around 6 p.m. and 70s around 8 p.m.
By Tuesday, rain is expected to arrive amid much cooler weather.
Barlow said there was a 50% chance of rain Tuesday evening, decreasing to around a 20% chance Wednesday morning.
Preliminary weather models show the storm could drop up to two-tenths of an inch of rain. Up to a foot of snow can fall in the high elevations of the Sierra Nevada.
“It’s the first storm of the season,” Barlow said. “And hopefully there will be more to follow.”
Once the rain has passed, temperatures will drop to a high of around 60 degrees on Wednesday and an even colder 58 degrees on Thursday. On Friday, temperatures will start to climb back into the low 60s.
“It’s going to feel like a shock to our system, but the time for sweaters has come,” Barlow said.
Although many will welcome the rain, Barlow reminds drivers to be very careful on the roads on Tuesday.
“We had a summer and half a fall of roads with no water on it,” Barlow said. “There is a lot of oil and dirt accumulated on the roads and as soon as the roads are wet it can make driving dangerous.”
