Area Forecast Discussion National Weather Service Spokane WA 1012 PM PDT Sun Jul 5 2020

SYNOPSIS. Warm and dry weather conditions are expected for Monday with temperatures warming into the 80s. A pair of weather systems pass through the region. The first system arrives Monday night into Tuesday with a second, Thursday. Each will bring breezy winds, cooler temperatures, a chance of showers and a few thunderstorms.

DISCUSSION. Tonight and Monday: A shortwave drops into the longwave trof currently sprawled across the Pac NW and coastal waters. This will bring a slight bump in heights across the Inland NW promoting dry conditions and few degrees of warming. Monday looks to be the warmest day of the week with widespread 80s common. A few spots around the southwestern Columbia Basin will be close to 90F or maybe a degree or two above. The shortwave will begin to pivot toward the coast Monday evening with increasing moisture spreading toward the Cascade Crest. The combination of afternoon heating and deepening moisture will bring a small threat for showers and thunderstorms with the greatest risk around Stehekin, Mazama, and into the Pasayten Wilderness. A second area of moisture and instability will begin to spread into NE OR and could reach the Blue Mtns by the late afternoon but thinking this will hold off until the evening hours or later. The remainder of Eastern WA and N ID will be warm and dry with light winds.

Monday evening and Tuesday: The shortwave will swing into the region Monday night, linger through Tuesday, and depart to the east Tuesday night. Monday night and Tuesday will be the most active weather periods. Showers will continue along the Cascade Crest Monday night into Tuesday morning however the main focus for thunderstorms will shift into SE WA and N ID with a good potential for nocturnal storms. Instability parameters have really ramped up in the last 24 hours with 700-300mb CAPE now expected to be on the order of 200-500 J/kg. Coupled with strong forcing along a potent shortwave pivoting inland, I see no reason to doubt this instability being utilized. There is some uncertainty exactly how far north or south these bands set up and this has caused the NBM to average out PoPs closer to 30%. Given a decent clustering of all deterministic models placing bands of precipitation across SE WA and N ID, we have increased PoPs over the NBM. Locations that carry the greatest threat for showers and storms include Blue Mtns, L-C Valley, Camas Prairie, Pullman, St Maries, Kellogg. Impacts from these bands of precipitation and embedded thunderstorms will initially be dry lightning and gusty winds as the boundary layer starts off quite dry but this should quickly moisten and we should see wetting rains possible within this corridor. Some areas will stand a shot for quarter inch of rain or slightly higher.

As the upper level trof shifts into WA on Tuesday afternoon, a renewed threat for showers showers and thunderstorms will come to the northern mountains of WA and slowly spread toward N ID in the evening. We do not anticipate strong storms but these slow moving cells could bring upwards of a quarter inch of rainfall. The greatest threat will for communities along the Canadian Border like Oroville, Chesaw, Laurier, and Northport. Some of this activity could expand as far south as Highway 2 around Wilbur, Davenport, Spokane, and Cd'A. The southern extend of these showers carry lower confidence as it battles midlevel drying wrapping into the trof from the west.

Winds for Monday evening and Tuesday will be breezy to gusty. Breezy winds will start Monday evening along the East Slopes of the Cascades around Wenatchee, Entiat, and Winthrop. This could lead to a few hours for elevated fire concerns with humidity levels near 25% as the winds start to blow. Winds will remain breezy overnight as the system moves in but humidity levels will be on the rise as the maritime air mass comes onshore. Gusty winds will expand across the Basin and Palouse on Tuesday raising some concern for spreading grass fires but once again, we do not expect critically low humidity levels. Wind gusts of 25-35 mph will be possible. Temperatures will be cooling back into the 70s for Tuesday. /sb

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 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.

Thursday through Sunday: 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 and the best chance of showers and isolated thunderstorms to be across the mountains. There will be cold fronts moving through Friday and again Sunday or Monday. It does not look like the four corners high strengthens and builds into the Pac NW anytime soon. /Nisbet

AVIATION. 06z TAFS: Clear skies and light winds will be the prevailing condition through the night and into mid morning. An approaching frontal system will produce a subtle increase in south winds late in the morning into the afternoon along with a some increasing high clouds. A PROB30 for thunderstorms has been added to the PUW and LWS TAFs after 03z for the potential of high based thunderstorms with the arrival of the cold front. /GKoch
