* Southwest Idaho BLM (ID Zones 400, 420, 423, 424, 426)...Hot
and dry today. Increasing moisture aloft brings increased clouds
and shower and storm potential Friday night and Saturday
afternoon and evening. Friday night into Saturday morning,
scattered showers with some weak embedded thunderstorms could
produce strong outflow gusts up to 45 mph and more isolated
lightning. Storms become stronger Saturday evening, but more
widely scattered, capable of outflow gusts up to 50 mph and more
lightning activity. Mixing heights around 11-12 kft AGL show
unstable conditions even outside of storms. Outside of storms,
winds are still breezy due to the frontal passage up to 25 mph.
* Southwest Idaho Forest (ID Zones 401, 402, 403, 421)...Hot and
dry today. Increasing moisture aloft brings increased clouds and
shower and storm potential Friday night and Saturday afternoon
and evening. Friday night, most activity will be scattered
showers with some weak embedded thunderstorms. Strong gusts to
45 mph are possible out of showers, but lightning activity will
be minimal. Stronger storms are possible Saturday evening, with
gusts up to 50 mph and better lightning potential. Abundant
lightning is possible. Mixing heights around 9-10 kft AGL show
unstable conditions even outside of storms. A weak cold front
will bring drier air to the area on Sunday with breezy
coniditions.
* Southeast Oregon (OR Zones 670-675)...Hot and dry today. A cold
front this weekend brings some scattered showers and isolated
lightning Friday night. Pre-frontal winds pick up on Saturday
with afternoon wind gusts up to 35 mph at the same time RHs are
10-15%. Isolated thunderstorms are possible over mountains and
the ID border on Saturday, but coverage will be limited. Storms
that do develop in this area will be fairly strong, capable of
producing lightning, outflow gusts up to 50 mph, and heavy rain.
Mixing heights around 11-13 kft AGL show unstable conditions
even outside of storms. A weak cold front will bring drier air
