Area Forecast Discussion National Weather Service Spokane WA 239 PM PDT Tue Jul 14 2020

SYNOPSIS. After a couple warm days on Wednesday and Thursday, temperatures will cool a bit as a weak Pacific cold front will bring breezy winds to the area along with a few mountain showers. The cool-down will be short-lived as temperatures warm into the upper 80s and 90s by next week.

DISCUSSION. Tonight through Thursday: High pressure will amplify into early Wednesday. By Wednesday afternoon a shortwave trof will be in better position just off the coast to help enforce an increased pressure gradient across the Cascades. Wednesday will be the warmest day of the workweek forecast for the Cascades coupled with some Wednesday afternoon and evening breezy gap winds as a result. Otherwise, the trof passes through Thursday will be marked with pops for weak shower activity and minor mention of possible weak pulse type short lived thunderstorms near the British Columbia Border. In addition the highest temps of the workweek forecast for locations other than the Cascades and close vicinity is set for Thursday. Post frontal northwest flow leave the coolest temperatures of the new seven day forecast anchored into Friday along with just enough instability and moisture to keep continued minor pops relegated to the mountainous periphery of the forecast area along with same small risk for weak pulse type thunderstorm activity within close proximity to the British Columbia Border. /Pelatti

Thursday Night through Tuesday: The period starts off with the cooling from the Thursday Pacific front. Friday will see a few instability showers over the mountains near BC, but for the most part the weather will be quiet.

Following that, a slight pattern change takes place. The ridge of high pressure in the eastern Pacific amplifies into the Gulf of Alaska, as well as into the northwest US. This allows us to warm up next week. At this point, temperatures in the Inland NW look to be solidly in the upper 80s and 90s throughout next week. This should really start to cure our fuels for rising fire concerns.

The fly-in-the-ointment is that this isn't the usual "hot summer" weather pattern that we typically see, which is normally associated with a 4-corners high amplifying over the western US. The current situation with an amplified eastern Pacific ridge leaves us open to Alaskan short waves moving over the ridge and dropping into our area from the north or northeast (also known as "back door" cold fronts). Such an event would bring cooler weather than in currently in the forecast. RJ

AVIATION. 00Z TAFS: Generally clear skies and VFR conditions will continue through the period with a few mountain cumulus this afternoon and scattered cirrus overnight. Winds will be light and diurnally driven. /Pelatti

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.
