NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
851 PM MDT Monday Jul 21 2014 


Discussion...for the most part...convection has been winding down 
in the past couple of hours as we head toward sunset. Most of the 
coverage was isolated with the bulk of activity occurring over southeast 
Oregon. This trend will continue overnight with isolated activity 
limited to the higher terrain after midnight. Evening forecast 
was updated for these latest trends. 


&& 


Aviation...VFR. Widely scattered showers this evening with 
isolated thunderstorms decreasing in coverage overnight and 
increasing again Tuesday afternoon. Surface winds variable 12kt or 
less. Winds gusts up to 35kt in vicinity of showers and 
thunderstorms. Winds aloft up through 10k feet mean sea level...SW 15-25kt. 


&& 


Previous discussion... 
short term...tonight through Wednesday...thunderstorms initiating 
on the edge of cloud shield/more stratiform precipitation from 
Rome through Stanley. Storms are better developed in the western 
Magic Valley with higher shear and high precipitable water values. Dew points in 
the middle to upper 50s suggest brief heavy rain will accompany the 
stronger cells /twf had a tenth of inch in 15 minutes/. Isolated 
storms across southeast Oregon are less organized and have shorter life 
spans. Scattered showers and isolated thunderstorms will continue 
through evening ending by midnight in most areas. Burns through 
Baker City area will see showers and thunderstorms through Tuesday 
morning as a weak shortwave moves across that area. Low confidence 
in thunderstorm coverage Tuesday afternoon. Most high res models 
suggest showers and thunderstorm development across southeast Oregon 
after 00z Wednesday. 0-6km shear would support better organized 
thunderstorms however...instability is limited with cloud cover 
from thunderstorms south of the Oregon/S southern border. The 
better chance for organized storms maybe across southeast of Mountain 
Home where better shear and slightly better instability /100-200 
j/kg bl cape/ exist. However...most guidance has little to no 
storm development across SW Idaho the 18z NAM and 12z GFS the only 
exception. Drier and cooler Wednesday across southeast Oregon Wednesday 
as the upper level trough moves east across Pacific northwest. 


Long term...Wednesday night through Monday...decreasing showers 
over the forecast area Wednesday night as the upper level trough 
moves east. Thursday a dry westerly flow will set up over the 
region and will remain over the area through Saturday. Temperatures 
on Thursday behind the exiting trough will average around 10 degrees 
below normal but will quickly warm back to near normal on Friday. 
Over the weekend and into next week models are trending toward 
rebuilding the ridge over the forecast area. Temperatures on 
Saturday will remain near normal but will warm to around 5 degrees 
above normal Sunday with even warmer temperatures on Monday.
