...there is a marginal risk of severe thunderstorms on thursday over
portions of the northern rockies into washington and oregon....
...summary...
isolated severe storms are possible on thursday over western
montana, northern idaho, into central oregon/washington.
...synopsis...
a broad upper ridge will be present on thursday over the central
u.s., with an upper low over ca and an upper trough over the
northeast states. scattered thunderstorms will affect much of the
southeast, southern and central plains, and northwest regions.
...or/wa/id/mt...
one area of concern for the potential of severe storms will be
across the northern rockies and pacific northwest states. models
depict one or more shortwave troughs rotating around the ca upper
low, providing ascent and strengthening wind fields across parts of
eastern or/wa, northern id, and western mt. confidence is rising
that a zone of sufficient instability/shear will develop to support
strong thunderstorms thursday afternoon. large hail and damaging
winds appear possible with the strongest storms.
