NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
310 am MDT Wednesday Sep 2 2015 

Short last warm day before a significant cold front 
Thursday. Models have slowed arrival of the expected 
through Baker and Harney counties 09z-15z Thursday...and Malheur County 
15z-18z Thursday. In Idaho the front should pass through the west 
central mountains 12z-18z Thursday and southwestern Idaho Thursday afternoon. 
Showers on the front will be mainly in our northern zones...but Steens 
Mountain and the owyhees will get a little rain also. Lower 
elevations in the south...including the snake basin...should stay 
dry. Light winds through afternoon will become moderate northwest 
late today and tonight then increase to 15 to 30 miles per hour Thursday. Maximum 
temperatures today will be like yesterday in the snake basin south to the 
Idaho/Nevada border...but as much as 10 degrees cooler than yesterday in Baker 
County. Lows tonight will be the 40s to middle 50s...due to 
cloud cover...showers..and winds. Highs Thursday will be about 15 
degrees cooler than today in southwestern Idaho and southern Malheur County...and 
about 10 degrees cooler than today in the north. 

Long term...Thursday night through Wednesday...ensembles and the 
ec and GFS all in general agreement in keeping long wave trough over 
our forecast area from Thursday night into the weekend...then the 
trough will move northeast with westerly flow aloft over area by 
Monday. A short wave on Tuesday looks to be be north of US...then 
hints of some short wave ridging by Wednesday. So we can expect 
cool conditions through Sunday with Friday and Saturday being the 
coolest with highs a good 15 degrees below normal. Then a warming 
trend will begin on Sunday and extend into Wednesday with temperatures 
slightly above normal Tuesday and Wednesday. As for 
chance will in be northern zones through Sunday and dry for Monday 
through Wednesday. 


Aviation...VFR. Smoke will continue to reduce visibility across east- 
central Oregon and west-central Idaho mountains increase in high ceilings 
today as a cold front approaches from the west. Frontal band should 
by over kbno to kbke to kmyl by 06z. West-southwest surface winds 
increase this afternoon with gusts of 20-25 kts in southeast Oregon and 
higher terrain SW Idaho. Southwest winds aloft of 20-30 kts through 
10k feet mean sea level.
