Drier air and slightly cooler temperatures are expected across the Inland Northwest today with lots of sun and highs in the middle 80s in Spokane and Coeur d’Alene.
The subtle weather change will be accompanied by breezy winds this afternoon with gusts near 20 mph.
A slow cooling trend through the weekend is being carried on upper-elevation winds blowing directly from the west off the Pacific Ocean.
The changing air flow will keep conditions dry and pleasantly warm through Saturday.
A weak low pressure system is forecast to drop into the westerly flow on Saturday and move inland by evening, bringing clouds, cooler temperatures and a 20 percent chance of showers by Saturday night through Sunday night in most locations.
Humidity levels are likely to drop into the teens during the warmest hours of the day, and lows at night could plunge to the 40s by Sunday night with some valleys near the Canadian border possibly seeing lows in the 30s, forecasters said.
On Wednesday, Spokane International Airport had a high of 87. The normal temperatures for this part of August are 83 for a high and 55 for a low.
Evidence of the cooling trend was seen this morning in Pullman where a temperature of 51 was reported at 7 a.m.
Elsewhere at 7 a.m., it was 59 at Spokane airport, 62 at Felts Field, 61 in Coeur d’Alene and 56 in Deer Park.
