Area forecast discussion, May 29, 8:03 PM PST, 1 hour 12 minutes before
Area Forecast Discussion National Weather Service Spokane WA 903 PM PDT FRI MAY 29 2015 .SYNOPSIS... Scattered showers and thunderstorms will continue this evening across the Inland Northwest as a weak shortwave trough moves through the area.Some of these storms will likely produce locally heavy rains and hail. Another round of showers and thunderstorms will likely develop late tonight into Saturday morning. Through the remainder of the weekend the main threat of thunderstorms will be confined to a small portion of southeast Washington and north central Idaho. Meanwhile most locations will see very warm temperatures with highs in the 80s. Thunderstorm chances will increase markedly on Monday into Tuesday as a strong upper level trough moves in from the south. Some of the storms on Monday could be strong and may produce large hail and strong winds. Unsettled and cooler weather will persist into the remainder of the work week with a threat of showers and thunderstorms each day. && .DISCUSSION... Update to remove mention of expired flood watch for the East Slopes North Cascades. No other significant changes made. /Pelatti && .AVIATION...00Z TAFS: Numerous thunderstorms producing hail, heavy downpours, gusty wind, and frequent lightning moving across the northern half of the aviation area will remain problematic this afternoon and evening. A second weather disturbance traveling through the forecast area tonight between 6-15Z is expected to produce forced elevated nocturnal showers and thunderstorms then daytime heating Saturday morning should allow for their diminishment if they have not already exited the area which may take as long as 18Z Saturday for it to occur. /Pelatti && .PRELIMINARY POINT TEMPS/POPS...
