Updated Aviation Discussion

.UPDATE...Latest radar data shows a band of rain extending across
eastern Oregon and southeast Washington with embedded heavier
convective showers. There have even been a few sporadic LTG
strikes this evening. Most of the lightning has been in Grant
county where the SPC Mesoanalysis page shows 100-250 J/kg of
MUCAPE. It doesn`t appear that t-storms will be a significant
threat tonight so will not add to the forecast. Otherwise added
some patchy fog for the Blue MTN Foothills of northern Oregon and
SE Washington for Saturday morning (extending the time period
from tonight into early Saturday) since at least some of the model
guidance suggests that fog could linger for a while into the
morning Saturday. Otherwise the current forecast is on track for
tonight and Saturday. 78
