Area forecast discussion National Weather Service Spokane Washington 436 am PDT Friday Sep 4 2015 Synopsis... a cool and showery weather pattern is expected for the remainder of the work week as a cold storm system moves by the area. Widespread rain is expected in the Panhandle and portions of eastern Washington on Saturday. Drier and warmer weather is expected by early next week. && Discussion... today through saturday: shower chances linger around the mountains before a broader rain threat expands in tonight into Saturday. Today low pressure migrates south from western Washington to western or. The associated deformation axis along the Cascades and shortwave rounding its east side will work afternoon instability to bring a threat of showers over the Cascades, as well as the Blue Mountains to central Panhandle mountains. A few shower may also form over the northern Panhandle mountains but the risk here will be low. This evening into the overnight the low pivots east-northeast toward the or/WA/ID border. Moisture wrapping into a developing trowal in tandem with the low and shortwave rounding it will bring expanding rain into southeast Washington and lower elevations of the central and southern Idaho Panhandle this evening. Overnight the rain threat will expand west into the Columbia Basin and Waterville Plateau and north into northeast Washington and north Idaho. By Saturday much of the region will have some threat of rain. Yet the area which will have the steadier and broader threat of precipitation will be within the vicinity of the trowal and activity elsewhere will be more scattered on its fringes. Models disagree precisely where that feature will lay, with some pushing it further west into the Columbia Basin than others. If this verifies it would allow for some decrease in the precipitation across the southeast Saturday afternoon. As for thunderstorm between tonight and Saturday there will be some risk. Tonight, especially overnight, models indicate a ribbon of elevated instability expanding into southeast Washington and the Idaho Panhandle. This is represented by some high level total totals between 35 and 40 c. So some embedded thunderstorms are possible here. By Saturday afternoon some SBCAPE develops with the best agreement across the Idaho Panhandle, northern mountains and Cascades. But some models show some convective instability across the Columbia Basin too. Overall there will be a threat of isolated to locally scattered thunderstorms but nothing too organized is expected, given the lack of significant shear or deep instability. Temperatures will remain below normal today and Saturday, with the coldest average temperature expected on Saturday with the trowal and steadier precipitation threat in the region. Some locations may not get out of the 50s or lower 60s Saturday afternoon. /J. Cote' Saturday night through Monday...looks like the weather will remain on the cool and wet side during this period as the medium range models are fairly consistent on ejecting saturdays low into Montana only to be swiftly replaced by another low dropping down from the northwest. Given this pattern, the best chances of precipitation on Saturday evening will be fixed over the Idaho Panhandle due to the placement of the upper level cold pool. Potential instability parameters suggest there will be a small chance of thunderstorms early in the evening, however warming aloft will eliminate any chance of thunderstorms during the late evening and overnight hours. For Sunday the next low is expected to cross the Cascades via SW British Columbia with the upper level jet extending from Seattle to Mullan Pass per the 00z GFS. If this verifies, any chance of precipitation will generally occur over the northern half of the forecast area, or generally north of Highway 2 in Washington and over the northern half of the Idaho Panhandle. The Canadian and ec show a slightly different scenario with the Canadian showing a much weaker shortwave trough remaining over BC, while the ec takes this second low and pushes it to the Washington/or border. Suffice it to say confidence is high there will be a secondary low, however where it GOES is questionable. No matter what the case, this second low will be weaker than the Saturday system and will contain less potential instability. It will also contain mid-level westerly flow Sans warm air advection. This means there will be a sizable rain shadow in the Lee of the Cascades. Even where the rain is expected to occur, precipitation amounts will be light. For Monday night through Tuesday night...any semblance of a low temporarily moves out of the region with either zonal flow or weak ridging replacing it. This suggests dry weather will prevail and temperatures will begin to warm. Speaking of temperatures, readings for the latter half of the weekend will remain significantly cooler than normal with highs in the mid 60s to mid 70s or nearly 10 degrees below normal. By Tuesday the jet will shift north of the Canadian border with temperatures surging toward normal values for the first time in nearly a week. Fx Wednesday through friday: a dry zonal pattern is expected to dominate this period with some weak ridging build into the region. This will keep any chance of rain for the region close to non existent. Temperatures will continue to creep warmer with highs expected in the upper 70s to low 80s. Overnight lows will range from mid 40s to mid 50s. /Jdc && Aviation... 12z tafs: a low centered over western Washington drops into western or between this morning and evening. A few -shra/-tsra will be a risk near the Cascades and Idaho Panhandle mountains. There is a risk some may pass by eat/omk this afternoon too, but the risk is small. The low pivots toward the or/WA/ID border tonight into Saturday morning, leading to an increasing rain threat for most taf sites after 01-05z, though the best chances may not develop further north near mwh/geg/Coe until after 06-09z and eat more likely will remain dry. Mostly VFR conditions are expected to continue, save for near puw/lws where lower cigs are expected to drop toward MVFR/LCL IFR conditions. But toward 12z Saturday areas further north will have a modest threat of seeing the flight category drop below VFR. /J. Cote' && Preliminary point temps/pops...
