Highs into 90s today, possible records Friday

Low pressure could bring lightning by weekend

Highs today are expected to climb into the lower 90s across the Spokane region, and then soar to near record temperatures on Friday before a low pressure system moves into the hot air and drops temperatures by more than 20 degrees on Saturday, forecasters said.

Downtown Spokane could see highs in the triple digits on Friday.

The weekend could see a new round of thunderstorms with the chance of rain pegged at 40 to 50 percent on Saturday and Sunday. Highs could drop more than 20 degrees on Saturday to the middle and upper 70s.

For today, highs under sunny skies are expected to be 91 at Spokane International Airport, 93 downtown and in Spokane Valley, 94 in Post Falls and 92 in Coeur d’Alene with light east to northeast winds.

Record highs are possible on Friday as a strong ridge of high pressure amplifies over the Inland Northwest along the Idaho Panhandle.

The airport should reach 98 on Friday, but downtown Spokane and Coeur d’Alene could go to 101 under intense sun.

Daily record highs for Friday are 98 in Spokane, 97 in Coeur d’Alene, 99 in Pullman, 97 in Moses Lake and 103 in Lewiston.

The high pressure system expected strengthen on Friday will be so strong that it is forecast to develop a kink in the mid-elevation air flow to the west, which will cause a low pressure area to form and move eastward with a cold front ahead of it. That, in turn, will cause a band of moisture to develop along the leading edge of the low as it migrates eastward to the Inland Northwest.

That band should have the greatest effect across southeast Washington and the central Idaho Panhandle, forecasters said.

Highs drop to the 70s on Saturday and rebound to the 80s on Sunday as the threat of thunderstorms diminishes. More warm weather is likely next week with highs in the upper 80s by Tuesday, forecasters said.

At 3 p.m., temperatures had hit 90 at the airport, 93 at Felts Field, 88 in Coeur d’Alene, 84 in Sandpoint, 95 in Pullman and 90 in Deer Park.
