.Update...
Have added some thunder across SE WA and the southern ID Panhandle
for this afternoon. Models advertising 500 mb temps of -30C to
-38C (depending on which model you believe) as the trough moves
through this afternoon. Models are also showing capes of 240J/kg
as well as lifted indicies of -1C. Currently have the thunder
threat mentioned across the WA and ID Palouse south and east
towards Lewiston and the Camas Prairie. We had some brief breaks
in the clouds this morning which has allowed temps to rise to the
lower 40s east of Highway 395 at Ritzville. Radar is showing a big
area of showers moving through the Tri Cities and Walla Walla area
and as it moves northeast think we could see some isolated
thunderstorms, or at least showers with small soft hail. /Nisbet
