Discussion...
forecast generally on track this morning with gusty winds
continuing down the Purcell Trench and Columbia Basin as well as
the Okanogan Valley. General speeds look to remain below advisory
limits with the exception of far southeastern Adams County near
Washtucna. A cwop observation platform is measuring sustained
winds 35-45 mph with gusts in excess of 50 mph. This appears to
be a local effect of the cooler dense air squeezing down the
Palouse River Valley with surrounding observations in Adams and
Whitman counties experiencing winds 15-25 mph and gusts to 35 mph.
As such, will handle with a nowcasts given the localized nature of
these speeds.
