Area Forecast Discussion
National Weather Service Pocatello ID
220 AM MDT Sat Jun 17 2017

.DISCUSSION...Isolated showers will linger in the eastern
highlands this morning as a minor upper trof exits the area. Upper
ridging will build up over the west by Sun...and continue to
amplify into next week. This will result in dry and warmer
conditions thru Mon. Models suggest some moisture flowing into
the area on Tue as the upper ridge flattens to zonal flow. This
may result in some aftn/eve tstms in the mtns Tue and Wed. By
Thu...the flow becomes a bit more northwesterly resulting in
dry...but cooler temps. Hedges

.AVIATION...Mid-layer cloud decks will likely linger this morning or
early afternoon before either high layer clouds take over or scatter
out. Showers or thunderstorms should not be an issue today. Winds
are expected to increase today at BYI and PIH with gusts around 25
mph. These winds are expected to improve this evening. No other
forecast concerns at the remaining terminals the next 24 hours.

.FIRE WEATHER...Isolated showers are forecast across portions of
Eastern Idaho through this afternoon and will mostly be confined to
zone 413. Breezy west and west-northwest winds are forecast with
gusts around 25 mph this morning across zones 427 and 425. Winds
will still be breezy this afternoon but gradually decrease through
by the evening hours. The remainder of SE Idaho will see winds less
than 20 mph with winds in fact light across Central Idaho today.
High pressure builds over our area going through the remainder of
the weekend which will allow for drying conditions and warming
temperatures. Expect Min RH values in the 20 to 30 percent range
both days with the exception of Eastern Idaho which will be more
moist today. Looking ahead, the warming trend will continue with
drying conditions persisting early in the week. RH values will drop
to 15 percent or less for portions of South Central and Central
Idaho Tuesday. NP/Hedges
