Area Forecast Discussion
National Weather Service Boise ID
848 PM MDT Sat May 11 2024

.DISCUSSION...Evening satellite imagery is clearing out as
cumulus development diminishes with sunset. It will be another
clear night, good for spotting any Auroral activity that
develops. Temperatures will run a few degrees warmer than last
night for those heading outside to watch the night sky. And for
those interested in if we might see the Aurora tonight, the
Space Weather Prediction Center in Boulder (www.swpc.noaa.gov)
has all the latest information. As of 830PM MDT, the energy
isn`t as strong as last night, but the last couple of hours have
seen an increase in the potential for a visible Aurora over
southeast Oregon and southwest Idaho. The current weather
forecast is on track for tonight.

&&

.AVIATION...VFR under clear skies through Sunday morning.
Increasing mid-level clouds across SE Oregon Sunday afternoon
with isolated showers and thunderstorms Sunday evening. Surface
winds: W-NW 5-15 kt, strongest KMUO to KJER/KTWF Sunday
afternoon with gusts to 25 kt possible. Winds at 10kft MSL: W-NW
10-20 kt.

KBOI...VFR under clear skies. Surface winds: light overnight,
becoming NW Sunday afternoon.

.PREV DISCUSSION...
SHORT TERM...An upper level ridge over the area will allow clear
skies to continue tonight with light winds. Mostly sunny
conditions are expected again on Sunday with afternoon
temperatures running about 15 degrees above normal. Afternoon
high temperatures on Sunday will reach the mid 80s in most lower
valley locations of southwestern Idaho and southeastern Oregon.
Mountain communities will see temperatures peak in the upper
60s and low 70s on Sunday. A series of shortwave troughs will
pass along the northern periphery of the upper level high
beginning Sunday evening causing the ridge to flatten out a bit
on Monday. Moisture will also begin to increase on Monday which
will bring scattered clouds into the area and about a 20 percent
chance of showers to the southern most portion of the forecast
area near the Nevada border.

Meanwhile...93 million miles away on the sun...a large group of
sunspots continues to erupt solar flares associated with a
severe (G4) to occasionally extreme (G5) geomagnetic storm.
NOAA`s Space Weather Prediction Center, in Boulder, Colorado, is
carefully monitoring the situation and is indicating that the
Aurora may be visible again tonight in a large area of the U.S.
including southern Idaho and southern Oregon.
