NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
303 PM MDT Thursday Aug 21 2014 


Short term...tonight through Saturday...isolated thunderstorms 
have popped up south and east of Boise and are moving east at 
10-20 miles per hour. This is the favored location for the rest of the 
evening. A hail spike was seen on dual pol radar on a storm near 
Hill City. Storm tops are around 35-40k feet mean sea level. Storms are 
expected to bring gusty winds and small hail. Near the Nevada border 
where high precipitable water and slower motions were noted brief heavy rain is 
also possible. After a lull late from late evening to early Friday 
morning a well organized period of showers and thunderstorms is 
expected Friday. This is due to a digging long wave trough with 
extra energy in the form of a shortwave vorticity which looks to be 
over southeast Oregon Friday morning and SW Idaho Friday afternoon. The 
short wave feature was observed on watervapor satellite imagery 
near 50n 130w this afternoon. GFS/NAM are within 3 hours timing the 
system across SW Idaho Friday afternoon. Late Friday afternoon a 
surface low is expected to shift east across the Idaho-Nevada border while 
aloft the digging upper low is expected to expand over Oregon. 
Friday night and Saturday this low will traverse SW Idaho followed 
by cool northwest flow at the surface and aloft by Saturday 
afternoon...throughout southeast Oregon and SW Idaho. High temperatures still 
expected to plummett to 10 degrees below normal by Saturday. Main 
change this package was to increase quantitative precipitation forecast and pop over central Idaho 
18z Friday - 06z Saturday. 


Long term...Saturday night through Thursday...cool upper level 
trough will be slow to move out of the forecast area as it is 
sandwiched in between two blocking highs...one over the central 
United States and the other in the northeast Pacific Ocean. The 
northeast Pacific Ridge will start to shift inland by Tuesday 
bringing warmer temperatures and drier conditions. The latest 
European model (ecmwf) model run builds the ridge off the West Coast just as the 
GFS has for the last few runs...increasing our forecast 
confidence. By Thursday the ridge begins to shift east allowing 
the flow to shift to a more zonal regime. Chances of precipitation 
will stay to our higher terrain mostly in the northeast. 


&& 


Aviation...VFR. Isolated showers and thunderstorms mainly south and 
east of ktwf this afternoon and in central Idaho mountains mainly 
east of ksnt. Surface winds generally westerly 12kt or less. Winds 
aloft at 10k feet mean sea level...SW 15-25kt.
