A quick warm up that began Tuesday afternoon will continue today, bringing the chance of temperatures in the 70s for the first time this year.
The National Weather Service is calling for a high of 74 in downtown Spokane, 73 in Post Falls and 72 in Coeur d’Alene and Spokane Valley.
The average high for today in Spokane is 65. The city saw a high of 66 on Tuesday.
Today’s warm weather will be punctuated tonight with a cold front passing over the region, bringing rain showers and cooler temperatures on Thursday when a high of 59 is likely in Spokane.
The low Thursday night could be a chilly 39.
Then, the warmer air returns under a moist southerly flow created by a low pressure system just off the West Coast.
Temperatures should rebound to the 70s for highs with lows in the middle 40s. The dew point will rise as the circulation brings moist air into the region. Showers are possible on Friday through Sunday.
Sunday could be a wet day with a 70 percent chance of showers and a high of 63.
Some of the wettest weather may be seen along the east slopes of the Cascades where forecasters are watching for fast stream rises from melting snow and runoff.
The milder air could send North Idaho rivers over their banks by Sunday, including the Coeur d’Alene River at Cataldo and the St. Joe River at St Maries.
The Kootenai and Moyie rivers will also be on the rise.
At 7 a.m., it was 49 at Spokane International Airport, 47 at Felts Field, 46 in Coeur d’Alene and 49 in Deer Park and Pullman.
