Area Forecast Discussion National Weather Service Spokane WA 1037 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. 06Z TAFS: Showers at the terminals have since ended with no additional precip expected through the forecast period. Low stratus and MVFR ceilings are again expected at GEG-SFF-COE Thursday morning although there remains uncertainty with the onset and breakup times. Otherwise, VFR conditions will prevail. Wilson

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
