...THUNDERSTORMS OVER CENTRAL AND EASTERN OREGON TODAY...
.DISCUSSION...Showers and embedded thunderstorms will continue
tracking northward this morning across central and eastern Oregon.
Later this afternoon, another round of more robust thunderstorms
is forecast, focused primarily on southern and eastern Deschutes,
Crook, and Grant counties. Afternoon thunderstorms will be
capable of producing strong, gusty outflow winds up to 60 mph,
small hail, and locally heavy downpours. Chances of wetting rain
through the evening are medium-high (50-80 percent for the Blue
Mountains) with low-medium chances (30-60 percent) for the rest
of central and eastern Oregon.
***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 the
transport wind multiplied by the mixing
height in 100`s of feet. Index 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.***
Note: Max transport winds may not occur
at the same time as max mixing height.
