Area Forecast Discussion
National Weather Service Pocatello ID
336 AM MDT MON SEP 26 2016

.SHORT TERM...Today through Wednesday. Look for patchy fog this
morning mainly along the Eastern Highlands with clear skies...high
pressure and lingering moisture. Expect dry conditions and
gradually warming temperatures through Wednesday with high
pressure ridging over the area. Look for temperatures around 5
degrees above normal today before becoming around 10 degrees
above normal by Wednesday. TW

.LONG TERM...Thursday through next Monday. Expect an active period
bringing back precipitation and much cooler temperatures. Remnant
moisture from a weakening low over the Southwest will be drawn
into our area ahead of a cold front that will move across our
area Sunday into Monday. Expect a slight chance of precipitation
late Thursday with better precipiation chances Friday into
Saturday, particularly across the Eastern highlands. Saturday will
be breezy with even stronger winds on Sunday. There will be a
brief lull in precipitation late Sunday into early Monday before
models show another system moving through late Monday. Look for
temperatures above normal Thursday and Friday before becoming
below normal by Sunday and even more so on Monday. TW


.AVIATION...VFR conditions anticipated through the forecast period
as high pressure builds into the region. Winds are expected to
remain generally light and terrain-driven. There is low-end
potential for some fog at KDIJ through about 15Z this morning, but
potential too low to include in TAF at this time. AD/TW


.FIRE WEATHER...High pressure will provide generally light terrain-
driven winds through mid-week. Lack of cloud cover and significant
winds will result in large temperature and humidity swings from day
to night, with excellent humidity recovery at night. Minimum
relative humidity values during the day through mid-week should fall
into the 20-30 percent range. High temperatures through much of the
week will be above seasonal normals. A disturbance will bring
increased moisture Thu-Fri with some potential for afternoon and
evening isolated thunderstorms. This disturbance will also bring an
increase in winds, with gusts to 30 mph possible at mid and upper
slopes, particularly during Thu and Fri afternoon and evening. A
strong cold front is slated to slide through the region this
weekend, bringing a significant cooldown and increasing
precipitation potential from the weekend into early next week,
along with breezy conditions. AD/TW
