Update...another active day is in the books...although not quite as
busy as Sunday. One large severe thunderstorm crossed I-84 and
deposited ping pong Ball sized hail. A few other severe storms
struck rural areas. The vertical wind shear weakened throughout the
day so the storms became less organized and slow moving...with heavy
rain becoming the primary threat. Things have quieted down
substantially and have updated the forecast largely based on the
latest NAM and hrrr models. They both develop an area of rain over
central Oregon tonight and move it northeast across northeast
Oregon. Have trended the pop forecast accordingly. Have also dropped
thunderstorms for the overnight period but will continue to monitor
lightning trends through the evening. 78

Aviation...06z tafs...VFR conditions will prevail through the
period. An area of rain/rain showers should develop overnight and
spread across kpdt and kalw through Tuesday morning. Otherwise
expect scattered showers to develop with daytime heating
Tuesday...especially over the mountains. There will be a chance of
thunderstorms over the eastern mountains east of the taf sites. Plan
on using vcsh during the daytime Tuesday rather than carrying a
shower group. Ceilings will be 5-7kft broken-scattered and middle level cloud
above. It will be breezy with west winds of 15 to 25 knots and some
higher gusts through early Tuesday evening. 78
