NWS Spokane, WA wrote its last area forecast discussion before the first event at Jun 29, 8:27 PM PST, 25 minutes earlier.
Area Forecast Discussion National Weather Service Spokane WA 927 PM PDT MON JUN 29 2015 .SYNOPSIS... A weather system will trigger isolated to scattered thunderstorm activity through early this evening. Tuesday and beyond will be mainly dry but continued very warm. Friday looks to be the warmest day this week...with valley highs ranging from 96 to 104. && .DISCUSSION... The line of thunderstorms that moved across the northern mountains are now pushing into extreme northwest portion of Montana late this evening. Quieter weather is expected for the rest of tonight. As such, we have let the Red Flag Warning expire. Skies will clear across much of the region. All the rain that fell across the Northern Panhandle may produce a brief period of fog in those valleys, but any fog should burn off quickly in the morning on Tuesday. /SVH && .AVIATION... 00Z TAFS: An upper level shortwave trough of lower pressure will pass across the northwestern portion of the region this evening. The atmosphere is also very unstable with thunderstorms developing rapidly over the Waterville Plateau and heading into the Okanogan Highlands. These thunderstorms are expected to remain north of the TAF sites, but these thunderstorms will be capable of producing strong thunderstorm outflows south and westward toward the Spokane/Coeur d'Alene areas through this evening. There is also a chance for thunderstorms to develop over northeast OR that pushes toward KLWS this evening; confidence is low that this convection will impact KLWS. /SVH && .PRELIMINARY POINT TEMPS/POPS...
