NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
850 PM MDT sun may 1 2016 


Discussion...a Rex block aloft /high pressure to our north and 
low pressure to our south/ will remain in place through Monday 
for dry condition and mostly clear skies. Good radiational cooling 
tonight with dry airmass and light winds for temperatures in the 
low 40s to upper 30s Monday morning. Mostly clear skies Monday and 
Tuesday. No updates needed at this time. 


&& 


Aviation...VFR under mostly clear skies. Surface winds...variable 
10 kts or less overnight...becoming easterly 10-20 kts on Monday. 
Winds aloft...east to southeast 10-20 kts through 10k feet mean sea level. 


&& 


Hydrology...the Bruneau and Jarbidge rivers continue to run high 
in Owyhee County. Above average snowpack exists in the upper Bruneau 
basin...particularly in the Jarbidge River watershed. Warmer 
temperatures this will week will accelerate snowmelt and keep the 
rivers running high. Rivers and creeks in these basins will need to 
be monitored as they respond to the increased runoff. 


&& 


Previous discussion... 
short term...about 4 degrees warmer Monday and another 4 degrees Tuesday. 
Min temperatures will rise more slowly...only a degree or so Monday and 
another degree Tuesday. Drying air mass and less wind will allow 
better radiational cooling at night and larger diurnal range. 
Rex block has formed aloft with high pressure in southwestern Canada and 
low pressure in the southwestern states and east winds over our area. 
The southwestern low will exit east Monday leaving only the upper ridge 
over the interior west. The ridge will shift east Tuesday and 
warmer/moister southerly flow aloft will begin as a Pacific trough 
nears the coast. This will lead to a slight chance of showers and 
thunderstorms Tuesday afternoon in eastern Oregon and higher mountains 
in Idaho. Surface winds will be light through Monday night then 
become southeasterly and increase to 10 to 15 miles per hour Tuesday. 


Long term...Tuesday night through Friday...a high amplitude upper 
level ridge centered over eastern Idaho Tuesday night will slowly 
move to the east. The slower movement will also slow down the timing 
of the next long wave trough that will move into the West Coast. 
Model trends weaken the trough and then split it as it continues 
to move to the east. The southern section of the split is forecast 
to be over Southern California by Friday. Expect slower timing of 
precipitation to spread over the forecast area. But not slow enough 
to make changes to the forecast. At this time looks like precipitation 
will spread into southeast Oregon Tuesday night but not move into 
southwest Idaho until late afternoon or evening on Wednesday. Wednesday 
night and Thursday will see the best chance of precipitation as the 
northern section of the split continues to move east and the southern 
section digs to the south. Precipitation will decrease over southeast 
Oregon Thursday night and Friday with continued chance over southwest 
Idaho. Models do differ on how far south the southern section of the 
split will go which means we could see precipitation near the Nevada 
border due to wrap-around moisture or will we be dry if it remains over 
the southern states. Will keep slight chance probability of precipitation over southwest Idaho 
for Friday due to uncertainty as to the placement of the low. 
Temperatures will be well above normal on Wednesday due to southerly 
flow ahead of the approaching upper level trough and will cool to a 
few degrees above normal by Friday. 


Saturday through Sunday...Pacific low still sits to our south with 
associated moisture rotating around it and impacting our area. A 
slow progression eastward is shown in the models for this low...but 
looks like things will start to dry out by Sunday afternoon for most 
areas. Southerly winds will help keep temperatures above normal 
through the period.

Boi watches/warnings/advisories... 
Idaho...none. 
Or...none.
