NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Pocatello Idaho 
306 am MDT sun Jul 5 2015 

Short and Monday. Moisture will continue to increase 
across eastern one storm drops out of Canada east of 
The Divide and helps pull another wave to our west across the 
state. We are already see that with cloud cover especially south 
toward the Utah border. Showers will really develop later this 
morning and afternoon...but the amount of thunderstorms will be an 
issue as cloud cover should limit across the southeast. We 
included more widespread showers with isolated thunder 
there...with scattered showers and thunderstorms everywhere else. 
Some of these storms will have locally heavy downpours with them. 
Where it ends up more unstable today...we wouldn't be surprised to 
see gusty winds and small hail. looks like storms 
will not be severe. We will see a front push over The Divide into 
eastern Idaho...but stall out about halfway through the area. This 
should act an additional focus for development this evening. 
Otherwise tonight...expect a decrease in showers and storms with 
scattered coverage only in the southeast corner. We should see 
winds pick up later today and continue for a while into this 
evening due to that front. For Monday...another weak wave drifts 
over Idaho a renewed chance of showers and storms tomorrow. The 
Magic Valley and south Central Highlands will likely see the least 
amount of coverage. Temperatures will be a lot cooler thanks in 
part to cooler air arriving but mainly due to more clouds. Keyes 

Long term...Tuesday through next Sunday. The weather will remain 
pretty active with showers and storms pretty much every day. 
Coverage will fluctuate depending on timing a couple of waves 
dropping from the north close to The Divide...and eventually the 
big low out to our southwest. The models are not agreeing on when 
that system is kicked our way by the next storm moving across the 
Pacific and toward the west. The GFS has it already into the 
northern plains by next weekend and farther south. The European model (ecmwf) takes 
a more westerly path across western Idaho and Montana and is 
slower as well. Based on the lack of confidence...we just made 
some minor tweaks here and there to the forecast. Besides the 
chance of rain...this pattern should also keep US from getting too 
hot. Highs will remain at or just above average. Keyes 


Aviation...a cold front will arrive today. Thunderstorms could 
affect some taf sites this afternoon. Otherwise expect windy 
conditions today. 



Fire weather....a cold front will arrive today. This will bring much 
cooler temperatures...gusty winds...higher humidity and a chance for 
thunderstorms today. Unsettled weather will persist through the week 
as a low pressure system slowly moves onto the California coast.
