Area Forecast Discussion
National Weather Service Boise ID
944 AM MDT Sun May 28 2017

.DISCUSSION...Skies were clear as of 930 am MDT this morning. We
expect isolated showers/thunderstorm in eastern Valley county
this afternoon/evening. Otherwise it will be mostly clear and
warm. No changes at this time.


.AVIATION...VFR under clear skies. Winds, variable and less than
10 kts, up through 10 KFT MSL.


SHORT TERM...No significant forecast changes.  Warming trend
will continue to Tuesday as upper ridge continues to shift
eastward.  Ridge axis will be directly over our CWA Monday and
Tuesday.  Models continue to show instability in the central Idaho
Mountains for a slight chance of showers and thunderstorms during
the afternoons and evenings there. Generally clear and dry
elsewhere. Light winds.

LONG TERM...Monday night through Sunday. The upper level ridge
remains over the area Tuesday which still is on track to be the
warmest day of the week for most locations. The next system can be
seen offshore Tuesday afternoon. Much better agreement among the
models with the tracking of this next system, but the GFS still
remains much more excited about the precipitation than the ECMWF.
Precipitation begins to hit SE Oregon by Wednesday afternoon.
Chances of showers remainS through early Friday, mostly for the
higher elevations. On Friday differences start to become apparent
once again among the models with the GFS keeping us in a much more
zonal pattern through early Saturday before another system passes
through Sunday. The ECMWF bringS this system in early Saturday.
Kept the forecast mostly on the dry side for now. Temperatures
show a slight cooldown after Tuesday, but still remain above normal.
