Area forecast discussion, Aug 19, 3:36 PM PST, 1 hour 14 minutes before
Area Forecast Discussion National Weather Service Spokane WA 436 PM PDT TUE AUG 19 2014 .SYNOPSIS... A cold front will pass through the Inland Northwest through Tuesday, bringing gusty winds, showers, and some thunderstorms. Cooler temperatures and the occasional threat of showers and thunderstorms will linger the rest of the week and into the weekend. However, the vast majority of this precipitation will be in northeast Washington and the North Idaho Panhandle. && .DISCUSSION... Tonight through Wednesday night...After today's cold front passage wind should increase and the associated showers and thunderstorms should decrease through the evening. Improvement expected for majority of locations with the exception of extreme Northeast Washington and North Idaho as the moisture feeding into the trof continues to influence that area for a longer interval. Additionally the models are showing more disturbances in the flow favoring passage in that location not to mention orographics are helping as well during the daytime hours. With the trof solution brought about by the cold front passage forecast temps show a substantial cool-down going into tomorrow and a bit on the cool side of what would be considered normal for this time of year. /Pelatti Thursday and Friday: The longwave trough over the western U.S. will deepen Thursday into Friday as a shortwave descends out of the Gulf of Alaska. The GFS, ECMWF and NAM have trended deeper and further west with the developing upper low Thursday night into Friday. Precipitation chances have been increased for the majority of eastern Washington and north Idaho for Friday. The track of the 500mb cold pool on the GFS and ECMWF raises some concern of locally heavy rain for north central Washington Friday afternoon/evening. If the 12z models hold true, the slow moving upper low will be near the Washington/Oregon border in the afternoon. Storm steering flow in this scenario would be northeasterly around 10-15mph in an increasingly unstable thermal profile. Fresh burn scars in the Cascades and north central Washington could be vulnerable to flash flooding and debris flows, so this situation will be monitored closely. /GKoch Saturday through Tuesday: Continuing shower chances and cooler than average temperatures mark this period. Models are in a bit better agreement today than yesterday, but the lack of solid run- to-run consistency still degrades confidence in the details. Saturday to Saturday night a 500mb trough moves from east OR to the MT/ID/WY border and the flow turns NNW across our region. A deformation axis stretches up into southeast WA, before weakening at night. At the same time a secondary and weak mid-level disturbance crosses the Inland NW during the afternoon and evening. Models show decent moisture with PWATs between 0.65 to 0.80 inches (or 110-150% of normal). These are highest across SE WA and the lower Panhandle. Instability is also decent during the afternoon, with SBCAPE averaging between 100-500 J/kg across the Blues through Central Panhandle and 100-200 J/kg across the Cascades and Canadian border mountains. All this points to shower and thunderstorm chances and a fair amount of cloud cover across southeast WA through the central Panhandle. Smaller shower chances will be found across the Cascades and northern mountains, while the rest of the area sees a mix of sun and clouds and drier conditions. The overall shower chances and clouds are expected to wane through the night as weak ridging begins to build in from the northwest. By Sunday that weak ridging briefly builds in, before the next system comes in Sunday night into Monday. On Sunday a few showers will be possible across the ID Panhandle, with the northwest flow and weak instability. Sunday afternoon into Sunday evening other shower chances approach the Cascades and Okanogan Highlands. Overnight into Monday clouds are expected to thicken over the remainder of the Inland NW overnight into Monday, with a chance of showers expanding across northeast WA and the ID panhandle. With PWATs rising to values comparable to this morning (130% of normal), the Spokane/C'dA area is included in this shower threat. Thunder will be possible overnight across northeast WA, particularly closer to the mountains, with some elevated instability. Thunder will also be possible Monday afternoon and early evening, especially around the mountain zones, with some SBCAPE. From Monday night into Tuesday models begin to diverge over how quick the system exits and shortwave ridging develops. This disagreement and the northwest flow will keep small shower chances alive across the ID Panhandle. Otherwise shortwave ridging is suggested from the west with a drying trend. But look for some breezy conditions Monday evening to Tuesday morning, especially over central WA with a tightening cross-Cascade gradient behind the exiting system. /J. Cote' && .AVIATION... 00Z TAFS: A cluster of thunderstorms will be in the vincity of the KGEG-KCOE corridor through 02z with gusty west winds, brief downpours and small hail. Meanwhile the bulk of the convection will lie across the northern mountains and near KMLP. The convection should decrease after 06z. Gusty westerly winds will be enhanced in KEAT, KMWH, KPUW and KWS while thunderstorms induced gusts will be found from KGEG-KCOE. VFR conditions are expected overnight into Wed morning. Another round of showers/thunderstorms are possible Wed afternoon mainly in the mountains. /rfox. && .PRELIMINARY POINT TEMPS/POPS...
