A partly sunny spring day is on tap with temperatures a few degrees below normal, but forecasters said the nicer weather is departing tonight.
The National Weather Service is calling for highs today in the upper 60s in Spokane and Coeur d’Alene before a new spring storm arrives, repeating a pattern that dates back nearly a month.
There is a 70 percent chance of rain showers on Wednesday and 60 percent Wednesday night, forecasters said.
Forecast models are showing a potential for a half inch of rain in 12 hours on Wednesday, they said this morning.
An upper-level low pressure area now along Vancouver Island in British Columbia has shoved last weekend’s summer-like conditions well to the east.
Forecasters said the low will migrate south into Oregon and then into Idaho. As it does, a batch of storm energy will circulate around the southern side of the low and then swing northward into Eastern Washington and North Idaho on Wednesday.
The rain will be contained in a band of moisture that will move from southeast Washington into the Inland Northwest and then exit to the northeast.
There is a 20 percent chance of showers tonight as the atmosphere destabilizes.
The chance of showers will continue at 60 percent on Wednesday night and 50 percent on Thursday before falling to a 20 percent chance of showers through the weekend.
Highs Wednesday are likely to be seasonably cool in the upper 50s before rebounding to the middle 60s on Thursday, the lower 70s on Friday through Saturday and middle 70s on Sunday.
Over the weekend, the greatest risk of showers will be over the mountains of Northeast Washington and North Idaho.
The normal high for today is 73 with a normal low of 49.
At 7 a.m. today, it was about seven degrees cooler than on Monday at the same time. It was 47 at Spokane International Airport, 50 in downtown Spokane and Coeur d’Alene, 48 in Deer Park and 47 in Pullman.
