NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
953 am MDT Wednesday Sep 17 2014 


Discussion...a lightning strike occurred in the Owyhee Mountains 
around sunrise indicative of instability there. Models however 
have only weak instability. High clouds have overspread most of 
our County Warning Area and kept nighttime temperatures mild again...and may take a couple 
degrees off maximum temperatures today but not enough to update for that. We did 
update sky grids but left temperature grids alone. Models also 
still entrain smoe of Odile/S tropical moisture and draw it into 
our eastern-most Idaho zones tonight and Thursday morning. Highest 
probability of precipitation are located there. Meanwhile...Pacific upper trough now 
moving toward the coast. Trough will close off a low when it 
reaches the southern Oregon coast Thursday. From there the low is forecast 
to move due south along the coast and eventually turn back toward 
our area late Sunday...quite different from earlier solutions 
which had a big upper ridge and hot weather over our area at that time. 


&& 


Aviation... 
through 09z...Oregon VFR high clouds with surface winds SW 15-25kts 
up to 35 kts at 10k feet through 09z. Idaho...mostly VFR with broken-overcast 
middle clodus at or above 15k feet mean sea level and isolated showers and thunderstorms. 
After 09z throughout broken-overcast 12-15k feet mean sea level with scattered showers 
and isolated thunderstorms...areas of mountains obscured and local 
MVFR in precipitation. Surface winds south to west 10-15kts shifting 
to west and northwest 10-20kts Thursday. Winds aloft SW to west 25-35kts. 


$$ 


Previous discussion... 
short term...today through Friday...southwest flow aloft increases 
today as an upper trough approaches the coast. Moisture and marginal 
instability will support isolated showers and thunderstorms over the 
eastern Boise Mountains today. Airmass remains warm and high temperatures 
are similar to yesterday. Elevated terrain across southeast Oregon and mountains 
of SW Idaho will tap into the stronger winds aloft and see gusts 
around 30 miles per hour by afternoon. The chance of showers and thunderstorms 
increases tonight as the upper low reaches the norther calif coast 
and a jet maximum tracks across the intermountain northwest. The chance of 
showers and thunderstorms continues on Thursday as the upper low 
weakens and slowly drops south along the California coast. Drier conditions 
Friday as a ridge builds into the Pacific northwest. Temperatures pull back from 
near record highs after today...but remain above normal throughfriday. 


Long term...Friday night through Wednesday...upper level trough 
will split and cut off from the jet stream late Friday night. As 
this happens the cutoff low will become situated in the center of 
the upper level ridge centered over the western United States. The 
cut off low will center itself over central California and pull in 
monsoonal moisture from the southeast. This cutoff low will slowly 
move northeastward over the Great Basin into our southern zones by 
Sunday for a chance of showers and slight chance of thunderstorms 
during the afternoon in our southern zones. The cutoff low will 
exit our region by Tuesday and a shortwave ridge will build into 
the region for drier conditions. Forecast confidence beyond 
Tuesday is low as the European model (ecmwf) brings in a trough from the Gulf of 
Alaska and the GFS builds a ridge over the area.
