148 PM MDT MON MAY 30 2016

.SHORT TERM...Today through Thursday night. A trough/closed low
pressure center will drift SE into and through Montana over the
next 24 hours. A trailing disturbance will aid in the generation
of isolated showers and possibly a thunderstorm into this evening
from Island Park down into the Teton Valley, with lesser chances
across the remainder of the Eastern Highlands. Dry weather will
then take hold overnight through Tuesday beneath the presence of
dry northwest flow. A weak disturbance will provide another slight
chance for shower and isolated thunderstorm activity across the
Divide east to Island Park Wed afternoon and evening...and again
on Thursday afternoon and evening. Precipitation coverage will
remain rather limited due to the relative absence of lower
atmospheric moisture content. A gradual warming trend will
commence this week, with high temperatures soaring to their
warmest seen yet this year, some 10 degrees above seasonal
averages by Thursday. AD/Hedges

.LONG TERM...Thursday night through Monday quitenight. A high
amplitude upper ridge will continue to dominate the West thru Sun.
This results in warm and dry conditions. The upper ridge begins to
be displaced eastward Sun night by an upper low moving into CA.
This may allow some moisture to flow into the area...resulting in
isold mtn tstms Sun and Mon aftn. Hedges


.AVIATION...Mainly for the Snake River plain, expect partly cloudy
skies with breezy winds of 15 mph and gusts near 25 mph this
afternoon behind an exiting cold front. Look for clear skies and
overall light winds tonight into tomorrow morning as high pressure
ridging starts to build in across the area. Wyatt
