Area Forecast Discussion National Weather Service Spokane WA 329 PM PDT Sat Jul 11 2020

SYNOPSIS. A cold front will bring cooler temperatures for Sunday with winds remaining breezy. Dry weather is expected Monday through Wednesday with temperatures gradually rising back up towards seasonal values. There is greater uncertainty in the forecast starting Thursday with a chance of showers possibly returning mainly to the northern mountains.

DISCUSSION.

. Dry and gusty winds into tonight .

Tonight through Sunday night: Increased southerly/southwest winds ahead of a trof expected to pass through tonight couples with dry conditions to allow for elevated fire danger in lighter grassy fuels in locations including some Cascade gaps and passes in addition to low elevations within proximity to including parts of the Columbia Basin. As a result red flag warnings and associated increased fire danger messaging remain in effect for this afternoon and part of tonight. Post frontal conditions Sunday will allow for cooler (about 15 degrees cooler) but still somewhat breezy and dry day. Minor pops for convection, mostly in the form of spotty showers, is in place tomorrow afternoon for weak surface based type very close but mostly north of the British Columbia Border. In addition minor spotty convection mention for late tonight near parts of the Idaho Panhandle, roughly near and south of a line from Pullman to Mullan Pass, is mentioned to address potential for forced convection ahead of the incoming cold front tonight. Sunday night is uneventful in comparison other than the trof positioning favors a cooler northwest flow, that with clearer skies and a somewhat conditionally unstable airmass influencing parts of the area which allows for more efficient radiational cooling to support cool Sunday night low temperatures that stand out as the coolest of the seven day forecast and well on the cool side of what would be considered normal for this time of year. /Pelatti

Monday through Saturday: Models are in good agreement of flat high pressure off the coast gradually nosing in Monday through Wednesday. This will result in a dry pattern and a gradual warming trend back up to normal temperatures. The models then diverge with a potential upper trough passage on Thursday. The deterministic run of the ECMWF is the most aggressive carving out a significant trough and a chance of showers over most of the region, while its ensemble mean show a trough as well but not quite as strong. The GFS Ensemble is the least aggressive and maintains a flat ridge while the Canadian is in between. The forecast currently leans towards the National Blend of Models which indicates a chance of showers mainly across the northern mountains both Thursday and Friday along with a few degrees of cooling. JW

AVIATION. 00Z TAFS: Cold front moving over TAF sites this evening and overnight will bring gusty westerly winds and it will remain gusty through the night. Clouds will accompany the front but overall, little to no precipitation is expected. Very minor potential for thunderstorms within very close proximity to the British Columbia border tomorrow after 18Z Saturday and an even smaller and more remote chance of what may be sprinkles or light showers near and south of a line from KLWS to KMLP after 6Z tonight just ahead of the cold front. /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.
