220 PM PDT Sat May 30 2026


.DISCUSSION...

Dry conditions are expected for much of the upcoming week. However
by Wednesday into Thursday, a weak system could bring showers and
the possibility of thunderstorms mainly to the mountains of
central and eastern Oregon. MIN RH values will be in the teens and
20s for much of the upcoming week. By late in the week, there
could be some breezy conditions, depending on the approach of an 
upper low off the coast. 


***Thunderstorms imply strong gusty winds           ***
***Winds are 20 foot 10 minute averages             ***
***CWR: Chance of wetting rain 0.10 or greater      ***
***Ventilation Index is derived from transport wind
   multiplied by the mixing height in 100's of ft.
   Categories are a generalized indicator and users
   are encourage to develop criteria that are 
   suitable and representative of dispersion 
   conditions in their local area of interest.
   Categories: low (< 200), moderate (200-500), 
   high (500-700), and very high (> 700). 
   -Note: Max transport winds may not occur 
    at the same time as max mixing height.          ***

...COOLER, BREEZY, AND DRIER THROUGH THE WEEKEND...

.DISCUSSION...

* Southwest Idaho BLM (ID Zones 400, 420, 423, 424, 426)... A low
  moving by to the east will bring cooler temperatures with breezy
  conditions today and Sunday, strongest in the Twin Falls BLM
  each afternoon. Showers will remain east of the area. Warm and
  breezy conditions will develop by midweek as another system
  moves by. Afternoon relative humidity will be low, dipping 
  below 20% each day starting Sunday with moderate overnight 
  recoveries.
 
* Southwest Idaho Forest (ID Zones 401, 402, 403, 421)... A low
  moving by to the east will bring cooler temperatures through the
  weekend. Showers and isolated thunderstorms will develop this
  afternoon across eastern portions of the forests with isolated
  activity returning Monday. Warmer temperatures will return next
  week with lower afternoon relative humidity and moderate to 
  good overnight recoveries. A system midweek will bring the 
  potential for showers and thunderstorms. 

* Southeast Oregon (OR Zones 670-675)... A low moving by to the
  east will keep temperatures cool with dry conditions through the
  weekend. It will be locally breezy, especially tonight across 
  northern Vale and Baker Valley. Warm and breezy conditions will 
  develop by midweek as another system moves by. Afternoon 
  relative humidity will be low, dipping below 20% each day 
  starting Sunday with moderate overnight recoveries.
