NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
941 PM MDT Tuesday Aug 4 2015 


Discussion...shower and thunderstorm activity which initiated 
over far southeast Oregon and the in/Nevada border is decreasing in coverage 
with sunset. Watching a second area of lighter shower activity 
over northern Nevada which is associated with an upper low circulation 
in northern California. Showers will develop across southeast Oregon and SW Idaho 
as the low center tracks to the NE overnight. Evening weather 
balloon from kboi showing elevated instability which would support 
potential for nocturnal thunderstorms given forcing from the upper 
low. However...confidence on coverage and strength of deeper 
convection that develops remains low. Newest model guidance hasn/T 
changed much with overnight forecast so will not update at this 
time. 


&& 


Aviation...VFR with increasing middle and high level clouds. Isolated 
showers and thunderstorms this evening mainly north of a kboi-ktwf 
line. After 05z scattered showers and isolated thunderstorms will 
spread over the entire forecast area and remain over the region 
through the night. Surface winds generally 10 knots or less...with 
gusty winds to near 30 knots near thunderstorms. Winds aloft 
westerly 10-15 knots up through 10k feet mean sea level. 


&& 


Previous discussion... 
short term...tonight through Thursday...an upper level wave that 
was moving northeast across northern California this afternoon will continue 
into southeast Oregon and SW Idaho overnight and Wednesday. This will bring a 
chance for showers and thunderstorms to the area overnight...which 
is relatively unusual...and which would make two nights in a row 
for many folks in the Boise area. These showers and storms will 
move east tomorrow...resulting in decreasing probability of precipitation in southeast Oregon 
through the day. As the system exits SW Idaho in the evening... 
probability of precipitation will rapidly decrease Wednesday night across the remainder of the 
area. Relatively dry zonal flow will come in Thursday...bringing a dry 
and mostly clear day. Temperatures will be 5 to 10 degrees below normal 
both Wednesday and Thursday...with overnight lows dropping considerably from 
tonight to Wednesday night. Tonight...with clouds around...lows will be 
around 5 degrees above normal. Wednesday night...with dry air and clear 
skies...expect lows around 5 degrees below normal. 


Winds near showers and storms today and tomorrow could gust 35 to 
45 miles per hour...and brief heavy downpours will accompany the stronger 
storms. Lightning is always a hazard with thunderstorms... 
regardless of the intensity of rain...hail...or wind. 


Long term...Thursday night through Tuesday...upper low off of 
the California coast will begin moving inland Thursday night into 
Friday morning. By Friday afternoon...showers and thunderstorms 
are expected to develop along the Idaho/Nevada border...and spread 
through the rest of the County Warning Area by Saturday morning. By Saturday 
afternoon...the low will have weakened and been partial absorbed 
into the westerly flow associated with a larger upper low off of 
the British Columbia coast. Nonetheless...the trough axis will 
have shifted east by this time so most convection is expected to 
be confined to the eastern most portions of the County Warning Area...especially 
the Idaho central mountains. Convective parameters do not look 
impressive Saturday afternoon...so surface heating and orographic 
lifting will be the main forcing mechanism. By Sunday...upper low 
off of the British Columbia coast will slowly drift southward and the area will 
transition into a southwest flow with some moisture transport to 
support some thunderstorms Sunday afternoon in the northern 
mountains. Southwesterly flow Monday and Tuesday will lead to an 
upper level low moving in from off the Washington coast by 
Wednesday. Disagreement in timing of the next system leading to 
low confidence in timing of any precipitation. Left probability of precipitation to model 
consensus and climatology for now. Temperatures linger right around normal.
