NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
1033 PM PDT Tuesday Jul 22 2014 


Synopsis... 
a strong storm system will move through the region tonight and 
Wednesday bringing the potential for thunderstorms and heavy rain. 
Cool and windy weather is expected for Thursday. Temperatures 
will rebound by the weekend and be accompanied by dry conditions. 
Hot weather will return to the area on Sunday and early next week. 




&& 


Discussion... 
minor update to adjust pops across the southeast zones and the 
Lower Basin. Regional radar mosaic shows a persistent band of 
showers and thunderstorms tracking northeast from the NE blue 
mts, across the Idaho Palouse and into western Shoshone County. 
There are also a few cells popping up over the Lower Basin with 
quite a bit of convection to the south that will track north over 
the next few hours. Cells are generally weakening as they move 
north into the forecast area. So far only light to moderate 
showers over the Cascade fires. There may be some stronger cells 
tracking over the fires later tonight or they may track just 
barely to the east of the fires. /Kelch 


&& 


Aviation... 
06z tafs: a low pressure system circulating off of southeast British Columbia 
will continue to push moisture across the inland northwest with 
showers and thunderstorms affecting all taf sites. The strongest 
thunderstorms are expected to develop over northeast or and track 
into southeast Washington and into the central portions of the Idaho 
Panhandle. Scattered showers and isolated thunderstorms will 
continue overnight. Confidence is highest that they will affect 
keat/klws/kpuw/kcoe. Lower confidence for kmwh/kgeg/ksff. -Tsra 
will be more widespread Wednesday afternoon and evening with 
thunderstorms capable of producing heavy rain, small hail and 
gusty outflow winds. /Ek
