Near-record highs are going to heat up the region today before cooler weather arrives for Thursday.

But summer is expected to hang on once a pair of low pressure systems moves through the area between tonight and Saturday.

The higher air pressure that has brought sunny, warm weather this week is reaching its crescendo today as a new low-pressure system pumps warm air and higher clouds ahead of it from the south.

Downtown Spokane and Coeur d’Alene are forecasted to reach 90 this afternoon under mostly sunny skies. An east wind up to 10 mph is likely in Spokane. Elsewhere, highs are expected to be 89 in Spokane Valley, Post Falls and Pullman.

The records for today for Spokane are 93 and for Coeur d’Alene, 92.

A cold front is expected to cross the Cascades moving from west to northeast about 11 p.m., bringing a 50 to 60 percent chance of showers and thunderstorms by Thursday. Most of the shower activity should occur by 11 a.m. Thursday.

Highs should reach the middle 70s on Thursday and then rebound to about 80 with sunny skies on Friday. Another low pressure area on Friday night will bring more clouds and a 20 percent chance of showers on Saturday. Sunday is going to feel cooler with a high of 71 under a return of sunshine. Improving weather is seen next week.

Autumn starts Tuesday afternoon.

At 7 a.m. today, temperatures were balmy with 60 at Spokane International Airport and 66 at Pullman. Elsewhere it was cooler with 56 at Coeur d’Alene, 54 at Sandpoint and 49 at Deer Park.
