NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
233 PM MDT Wednesday Sep 2 2015 


Discussion...strong low pressure disturbance continues to move 
south along the coast towards southern Oregon and northern 
California. Some southerly flow into southeast Idaho this 
afternoon with potential for subtropical moisture slipping into 
the south central and Caribou Highlands this evening and 
overnight. Latest satellite and radar imagery suggest this has 
been delayed a bit and the 18z nam12 and rap model also favor 
timing closer to midnight and early morning. The remainder of 
southeast Idaho remains dry tonight. Thursday and Thursday night 
still looking for the eastern edge of the low to brush Custer 
County with a few showers as it moves south. There will be a few 
trickles of moisture slipping into the eastern Highlands from the 
south as well. Southerly winds Friday will be breezy in the south 
Central Highlands and snake plain. 


Model consensus has the low moving east into Idaho Friday night 
and Saturday for scattered showers and isolated thunderstorms over 
the forecast area. By Sunday the pattern quickly reverts back to a 
mild west to northwest flow that is large dry except for may near 
Monida Pass on the Montana border. There are some model 
differences with a minor disturbance that crosses north Idaho and 
Montana on Monday and nipping this area with spotty showers...then 
it is back to a dry pattern the later part of the week. Receiver station

Aviation...models project a disturbance to move north out of Utah 
this evening and produce showers for kpih and kida. An isolated 
lightning strike cannot be ruled out...but not enough confidence to 
include in tafs. The disturbance will continue northward and will 
likely exit into Montana/Wyoming before sunrise. Hinsberger 


&& 


Fire weather...red flag conditions continue through 9 PM this 
evening due to gusty winds and low humidity. A strong southwesterly 
boundary layer flow ahead of a cold front will impact the central 
Idaho mountains. This flow particularly favors dry/warm downslope 
winds in the valleys until just after sunset tonight. The cold front 
will stall over the central mountains overnight and pass through 
Thursday night. Humidity is generally expected to recover and winds 
should not be as strong on Thursday. Moisture increases Saturday as 
southerly flow is enhanced ahead of a deep upper low...which may 
bring wetting rains to the central mountains. The low will also 
bring the threat of thunderstorms as the airmass becomes more 
unstable. Hinsberger

Pih watches/warnings/advisories... 
red flag warning until 9 PM MDT this evening for idz410-475-476.
