   NWS Storm Prediction Center Norman OK
   315 PM PDT Mon Aug 17 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western Idaho
     Central and eastern Oregon
     Southeastern Washington

   * Effective this Monday afternoon and evening from 315 PM until
     1000 PM PDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 75
       mph possible

   SUMMARY...Ongoing severe thunderstorms over southeastern Oregon may
   continue to pose a severe-wind threat as they move into a marginally
   unstable environment across parts of western Idaho.  Additional
   thunderstorms forming over central/northeastern Oregon, as far
   southwest as the Bend area, also may offer sporadic severe gusts
   while crossing the rest of the watch area this afternoon and early
   evening.

   The severe thunderstorm watch area is approximately along and 95
   statute miles east and west of a line from 15 miles west southwest
   of Burns OR to 90 miles north of Mc Call ID. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU6).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   1 inch. Extreme turbulence and surface wind gusts to 65 knots. A few
   cumulonimbi with maximum tops to 500. Mean storm motion vector
   22035.

Please visit the National Weather Service Interactive Weather Information Network (IWIN) for more information on the warnings.

For each watch, probabilities for particular events inside the watch (listed above in each table) are determined by the issuing forecaster. The "Low" category contains probability values ranging from less than 2% to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities), "Moderate" from 30% to 60%, and "High" from 70% to greater than 95%. High values are bolded and lighter in color to provide awareness of an increased threat for a particular event.
