Area Forecast Discussion National Weather Service Spokane WA 443 PM PDT Wed Jul 1 2020 .SYNOPSIS... After a very cool start to July, warmer weather is on the way. Thursday should see most of the showers confined to the northern mountains. The holiday weekend should see temperatures in the upper 70s and 80s with mostly sunny skies. Sunday could have a few mountain showers. Rain returns to the forecast by Tuesday with a cooling trend. && .DISCUSSION... Tonight through Friday: After a chilly 1st of July where temperatures were about 20 degrees below normal, the forecast weather should be warming and drying. Showers will continue tonight across the northern WA mountains and in the Panhandle. For Thursday, yet another low pivots onshore from off Vancouver Island. But this low should track far enough north of our area to keep the Inland NW dry, except for some shower chances along the BC border. Temperatures will be a bit warmer tomorrow, but not by a lot over today. Still, skies will have more sunshine than today. Friday should add 5-10 degrees over Thursday's readings, with just about everyone at least in the upper 70s and lower 80s. RJ Friday night through Wednesday: Little change is expected in the upper level pattern through the weekend into next week. Low pressure will remain over off the coast of BC with a ridge of high pressure over the middle of the country. This will keep a southwest flow aloft over the Inland NW. Minor waves rotating around the low will enhance lift in addition to orographics, giving way to a chance of afternoon mountain convection. This looks to develop over the Blue mountains into north central Idaho as early as Saturday with chances spreading to the northern mountains by Sunday afternoon. In addition, westerly gap winds are expected to increase in the evenings from the lee of the Cascades into the Columbia Basin. The upper low weakens to an upper trough by Monday and pivots inland, meanwhile more energy fills in and renews the trough off the BC coast. There’s some solutions showing another upper trough passage through the region by mid week. Overall, the threat of afternoon mountain convection will return each day with locally breezy evening gap winds. Little deviation expected in temperatures as they remain at to near seasonal levels for early July. /rfox. && .AVIATION... 00Z TAFS: Scattered showers expected into this evening across northeast Washington and into the Idaho Panhandle.
