NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
159 PM MST Friday Jan 30 2015 


Short term...tonight through Monday night. 
Southeast Idaho remains under the influence of a high pressure ridge 
as one disturbance slides through Montana Saturday and another over 
the southwestern states pulls further away from US. That leaves 
inversions and patchy fog for tonight and Saturday night. A plume of 
moisture associated with the low in the Pacific near 160w will 
advance across southeast Idaho Sunday night through early Tuesday 
morning. Models have certainly been jumping around with the 
moisture. For this forecast...came up with 1 to 5 in the 
mountains...5 being on the ridge tops. Monday night less than 1 inch 
in the Lower Valley floors....and temperatures sneaking above 
freezing on Monday. Receiver station 


Long term...Tuesday through Friday. We will eventually see a 
transition by the end of next week to a stronger ridge over the 
west. Before that...we are still dealing with moisture streaming off 
the Pacific and into Idaho. We should a decent chance of rain and 
snow across the north which is supported by the models and ensembles 
to an extent. Farther south...the models want to keep a lot moisture 
around especially in the mountains Tuesday and Wednesday. That is 
not supported necessarily by many of the ensemble forecasts. Because 
of that we only made some minor changes to the forecast...keeping 
higher chances up north with a least a slight chance across more 
southern locales. After that...we continued with drier conditions. 
It will be interesting to see how strong the ridge builds. The 
models want to break it or shove it east rather quickly heading into 
next week. That might be too quick. Expect warming temperatures when 
we transition to the ridge...as temperatures outside of inversion 
areas will try and push above 50 in some locations. Keyes

Aviation...we continue with VFR conditions at all four of our taf 
sites this afternoon...with high and middle level clouds around. We do 
have some pockets of stratus and fog around this afternoon. The 
closest area to any taf site is north and west of kbyi. Wind 
direction and moisture profiles suggest as the wind continue to turn 
more from the west...IFR/potential LIFR conditions rush back up the 
snake plain. The forecast follows that trend with stratus and/or fog 
returning to kbyi and kpih through the evening hours. Kida is a 
little more iffy on that because the winds stay northerly and keep 
slightly drier air in place. We did put these conditions in at kida 
after midnight...but confidence is obviously lower. It is possible 
that it may happen because of the nearby Snake River vs the other 
scenario. Ksun is expected to stay VFR although there is a slim 
chance that fog/stratus is sucked into The Wood River Valley if 
winds turn southeast. Conditions will begin improving later 
Saturday. Keyes
