Area Forecast Discussion National Weather Service Spokane WA 430 AM PDT Mon Jul 13 2020

SYNOPSIS. The weather will gradually warm up for the first half of the work week, with Wednesday likely the warmest day of the week. A Pacific cold front will cool temperatures a bit for the second half of the week and bring some showers to the northern mountains and breezy winds to the Columbia Basin. Next weekend looks mild with mountain showers in the north.

DISCUSSION. Today through Wednesday night: We are looking for a few days of quiet weather as northwest flow becomes established aloft between high pressure off the coast and lower pressure over Central Canada. Weak pressure gradients within this regime will promote light, diurnally driven winds for much of Monday and Tuesday. Wind speeds are expected to be around 10 mph or less. Temperatures will start off well below normal Monday with highs in the mid 70s to low 80s but should rebound Tuesday closer to mid July standards or 80s. The air mass will be dry which will allow for some cool nights. Morning lows in some of cooler mountain valleys or known cold spots in the Basin will dip into the low to mid 40s. A weak wave will ripple through the area on Wednesday bringing some high clouds but no precipitation. Main impacts will be the kick up the winds slightly leading to some afternoon and evening breezes around 15-20 mph. This enhanced mixing will help warm our environment a few more degrees pushing afternoon highs back into the mid 80s to lower 90s. /sb

Thursday through Sunday: As a ridge of high pressure remains firm over the eastern Pacific, a prevailing west to northwest flow aloft will span across the Inland NW. This pattern will be susceptible to energy rounding the ridge and generating troughs downstream across the western Canadian provinces. The deterministic 00z models are showing better agreement on this scenario as suggested in the ensemble members.

One such shortwave is expected to carve a trough over B.C. on Thursday with the axis brushing across the WA/Canadian border around Thursday afternoon and night. Moisture advection will increase pwats over the region to around three quarters of an inch. Instability looks weak by able to generate showers with isolated thunderstorms across the northern mountains. Thursday will still be quite warm with widespread 80s to lower 90s. A cold front will accompany the passage of the upper trough and bring breezy westerly winds Thursday afternoon and evening. Friday will be several degrees cooler with locally gusty winds while the chance of showers with embedded thunderstorms returns Friday afternoon and evening.

The upper trough remains over western Canada through the weekend as more shortwave energy digs south across the Inland Northwest. This will keep the threat of convection across the northern mountains. Locally gusty winds return each afternoon and evening while temperatures remain slightly cooler than normal. Looks like the warmer and dry summer weather will hold off until later next week as depicted in the 8-14 day outlook and the extended ensembles. /rfox

AVIATION. 12Z TAFS: Light west to northwest winds will be in place today. Cannot rule out a sporadic gusts to 15 mph around Pullman and Lewiston but as diurnal winds line up with the weak pressure gradients but overall confidence in timing is low to include in TAF. Skies will generally be clear outside some orographic cirrus skirting across southern WA and around Lewiston. /sb

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.
