NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
859 PM MDT Tuesday Aug 19 2014 


Discussion...thunderstorms in eastern Oregon and over the 
owyhees sent an outflow boundary through the Treasure valley this 
evening. The boundary has weakened but may still move into the 
western Magic Valley through midnight...although winds are 
expected to be lighter. The coverage of the showers and 
thunderstorms has decreased...but isolated showers and 
thunderstorms continue in SW Idaho and portions of southeast Oregon. 
Drier stable air has entered Baker County and northern Harney 
County. Will update to end showers and thunderstorms in those 
areas for the remainder of tonight. On Wednesday...the shower and 
thunderstorms will favor SW Idaho as the drier air continues to 
work into southeast Oregon. 


&& 


Aviation...VFR...except until 07z...isolated thunderstorms over 
Boise Mountains and the Owyhee Mountains. Isolated thunderstorms 
will redevelop over much of southeast Oregon and southwest Idaho 
after 20z. Surface winds northwest 5-10 kts increasing to 10 to 15 
kts after 18z...winds gusts to 35 kts vicinity thunderstorms after 
21z. Winds aloft northwest 10 to 15 kts through 10k feet mean sea level. 


&& 


Previous discussion... 
short term...tonight through Thursday...water vapor imagery over 
southeast Oregon and SW Idaho shows moisture and isolated thunderstorms 
.Especially along an axis from south of Jordan Valley towards 
central Idaho south of Atlanta. Thunderstorm convective activity 
with gusty winds 35 miles per hour to locally 50 miles per hour and small hail is expect 
across southeast Oregon and SW Idaho... especially this evening. Embedded 
impulse over north/central Nevada looks to lift across south central Idaho 
overnight so nocturnal storms are possible too. West/v also shows the 
western axis of the first impulse near the Cascade crest which is 
expected to pivot to along a Burns-McCall axis Wednesday. Morning. This 
will bring drying and stabilization behind it to about the northwest 2/3 
or 3/4 of the area. By Thursday more dry cool air drops into the 
trough over the northwest 3/4 of the area. A surface low is now expected 
to form on the front and stall a wavy trough axis or front over 
S-central Idaho through Thursday evening. This will be the focus 
for showers and thunderstorms. The next two days could see around 
one third of an inch of precipitation across southern Twin Falls 
County...though models range up to around 0.6 inches. Highs will 
be cooling off in this pattern while lows will vary from mild 
under clouds to much cooler with dry air across southeast Oregon to the 
central Idaho mountains main change this package was to raise probability of precipitation and 
quantitative precipitation forecast across southern Twin Falls County. 


Long term...Thursday night through Sunday...good model agreement 
and run to run continuity give above average confidence that 
temperatures will remain below normal. Thursday night the upper 
level trough over the northwest states will be reinforced by a 
secondary trough moving south out of b.C. Maintaining the 
relatively cool weather along with isolated showers and 
afternoon/evening thunderstorms mainly over the higher terrain. 
The trough is expected to shift east Saturday night leaving our 
area under northwest flow aloft accompanied by gradual warming and 
drying. 


Sunday night through Tuesday...the models are consistent in showing 
a continued dry northwesterly flow sitting over our region due to a 
blocking high over the east Pacific. Temperatures will stay below 
normal during this pattern and most of our County Warning Area will be precipitation 
free except for the higher terrain in the NE which will be affected 
by high middle-level humidity brought in from the north.
