Area Forecast Discussion
National Weather Service Pocatello ID
213 AM MDT MON MAY 30 2016

.DISCUSSION...Surface cold front will be pushing through the area
this morning but will come with no appreciable moisture. Strong
subsidence in the mid-levels should suppress most convection
across the area. Post-frontal winds are enough to warrant keeping
the Lake Wind Advisory in effect for today, though models have
been trending downward with windspeeds. Winds will swing around
from the north/northeast tomorrow and may present another day of
Lake Wind criteria to the American Falls Reservoir.

For the rest of the week and into next week, a strong ridge of
high pressure will continue to keep dry and warm conditions in the
forecast. GFS and ECMWF present similar solutions with regards to
the amplitude and location of the ridge, though the ECMWF has been
somewhat stronger in previous runs. Guidance is pushing highs near
90 degrees next weekend. Hinsberger

.AVIATION...Dry conditions expected across east Idaho today with VFR
conditions through tonight. Surface gradient behind front will
strengthen today and winds 15-20kts through the Snake Plain can be
expected this afternoon and early evening. DMH


.FIRE WEATHER...The shortwave axis and associated cold front have
moved through east Idaho. Tightened surface gradient behind the
front will allow for breezy to locally windy conditions through the
Snake Plain. Otherwise a ridge of high pressure will build into the
region for the remainder of the week. Temperatures will warm above
seasonable levels by the end of the week with daytime humidities
falling into the teens in most locations. DMH


.PIH Watches/Warnings/Advisories...
Lake Wind Advisory from 10 AM this morning to 8 PM MDT this
evening for IDZ021.
