Area Forecast Discussion National Weather Service Spokane WA 205 PM PDT Mon Jul 6 2020
SYNOPSIS. Expect a pair of weather systems to pass through the region this week. The first system arrives Monday night into Tuesday with a second, Thursday night into Friday. Each will bring breezy winds, cooler temperatures, a chance of showers and a few thunderstorms. Generally cooler than normal and potentially breezy weather continues into the weekend.
DISCUSSION. Tonight through Tuesday night: An upper level trough centered off the WA/OR coast this afternoon will move east over the area into Tuesday. Tonight models are in good agreement of elevated convection firing along and ahead of a cold front over SE Washington into the ID Panhandle. Initially this activity looks to develop over Oregon this evening before tracking NE into our region overnight. With elevated CAPE of 100-400 J/KG and moderate forcing with the incoming trough some lightning activity is expected but given low values of elevated CAPE current thinking it will be mainly isolated in coverage. Models show the most favored areas to be from the palouse extending northeast into the Central Panhandle Mountains. Although some of the higher res guidance develops convection as far west as the Tri-Cities area up through Spokane and Sandpoint so have mentioned a slight chance of thunderstorms for these areas as well.
This axis of elevated convection slides east into Montana by late Tuesday morning before a second round of showers and thunderstorms develops over the northern mountains Tuesday afternoon/evening under the cold pool aloft. These storms will likely feature brief downpours, gusty winds, and potentially small hail. This activity is expected to remain north of the Spokane/Coeur d'Alene areas. Further south breezy winds will be the main story across the Wenatchee area, Columbia Basin, West Plains, and Palouse with gusts in the 25-35 MPH range, except locally 40 MPH in the windy spots such as Wenatchee, Waterville, and Vantage. This will raise the concern for fire spread in dry grass but relative humidity should remain above critical thresholds. JW
Wednesday: A shortwave ridge will move through the region for mostly dry conditions. There will be a slight chance of afternoon showers right along the crest of the Cascades and near the WA/ID/Canadian border. Even though skies will be mostly clear to partly cloudy, temperatures will remain about 4 to 7 degrees below average. The GFS, EC and Canadian ensembles all have low 70s for Spokane, which is still several degrees cooler than what the blend is showing. Have trended towards the ensembles and have valley temps in the low to mid 70s for NE WA and N ID with near 80 across central WA. The EC ensemble member is showing afternoon wind gusts across portions of the eastern Columbia Basin into the Palouse and Spokane area. Gusts will not be as strong as Tuesday, but gusts 15-25 mph is possible during the afternoon.
Thursday through Monday: The persistent trough pattern we have been in for the last few weeks will continue through this period. This will keep our temperatures at or a few degrees below average. The ensemble models all suggest temperatures several degrees cooler than what the NBM is showing. Have trended the temperatures down a few degrees. It looks like Saturday will be our warmest day during this period, with temps right at average . 80s. The best chance of showers and isolated thunderstorms will be across the mountains during the afternoon hours. There looks to be a front that moves through Thur night/Friday morning. GFS is showing some elevated instability moving into the Camas Prairie and southern parts of Shoshone county. Confidence is not high this far out, but do have mention of a slight chance of thunder through the night. Friday afternoon could be another locally breezy day . mainly for the Ritzville/Spokane/Pullman/Walla Walla areas. /Nisbet
AVIATION. 18Z TAFS: Mostly clear skies and terrain driven winds less than 10 kts will continue through the afternoon. A cold front will pass through tonight into Tuesday AM. From 06Z- 12Z, there will be an increase chance of showers and thunderstorms at KPUW/KLWS with KCOE expected to be on the fringes. There is a small threat of this activity also impacting KGEG/KSFF but confidence too low to include in TAF. Winds will be picking up at KEAT around 01Z with gusts to 20-25KT. Conditions will remain VFR across Central and Eastern WA, with some MVFR conditions possible in the ID Panhandle 12-18z TUE. JW

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.
