Area Forecast Discussion
National Weather Service Boise ID
304 AM MDT WED JUL 27 2016

.SHORT TERM...Today through Thursday...Another shortwave trough is
moving east toward the area today. This will once again provide
lift and a slight increase in moisture, resulting in isolated
showers and storms mainly in northeast Valley County. Otherwise
expect another hot and dry day. Skies will be mostly clear except
in northeast Valley County and near the Pioneer fire, where an
impressive display of pyrocumulus developed yesterday afternoon
and early evening. Smoke from the Pioneer will continue to impact
much of the Boise Mountains, and drain back into parts of the
Upper Treasure Valley. Winds will generally be 10 kts or less
today, with a slight increase tomorrow, especially from Mountain
Home east into the western Magic Valley. Lows tonight will once
again hold about 5 degrees above normal, while daytime highs both
today and tomorrow reach 5 to 10 degrees above normal. Finally,
the upper level flow will come out of the WNW tomorrow, bringing
drier air into the region and eliminating the chance for showers
or thunderstorms.

.LONG TERM...Thursday night through Tuesday...Mostly clear and
continued hot Friday under dry west-northwesterly flow aloft. Flow
aloft will back to southwesterly Friday night with even hotter
weather for our area Saturday, although the flow will also bring
modest monsoon moisture in and clouds may hinder full warming. The
moisture will bring a slight chance of thunderstorms Saturday and
Saturday night. Upper trough from the BC coast will come in Sunday
followed by a reinforcement Tuesday. The trough will push the
monsoon moisture out to the east with dry weather for our CWA
Sunday and beyond. Temperatures will cool to normal Sunday and
Monday then dip slightly below normal Tuesday.


.AVIATION...VFR under mostly clear skies. Local smoke and MVFR
visibility near Lowman, ID. Scattered afternoon cumulus over the
mountains 18Z-03Z. Isolated thunderstorms in the central Idaho
mountains 21Z-01Z. Light surface winds through 18Z then becoming
west-northwest 10-15KT, decreasing by 02Z. Winds aloft near 10KFT
MSL west-northwest 10-15KT.
