Debris Flow in Idaho, May 1, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1033 PM PDT Mon Apr 30 2012

.SYNOPSIS...
A number of weather disturbances will move over the area this
week. The result will be below normal temperatures and occasional
intervals of rain showers in valleys with rain and snow showers
over mountains. Light snow accumulations are possible in the
mountains from time to time. Breezy to locally windy conditions
are also expected at various times for much of the week.

&&

.DISCUSSION...
Convection is diminishing across eastern Washington while the
secondary shortwave is rotating across the northeast corner of
Washington into the far northern Panhandle. Expect showers to
linger over the Panhandle mountains through midnight due to
upslope flow. There were several lighting strikes this
evening...especially near the Canadian border and over the
Palouse. This activity has quieted down with loss of daytime
heating. The gusty winds will settle down as well while speeds
will remain steady through the night under the swift westerly flow
aloft. /rfox.

.AVIATION...
06Z TAFS: The shower activity has pushes toward the Canadian border
and the Panhandle mountains, although there has been some renewed
shower activity near KPUW that will persist through 08z. Otherwise
the showers have left the TAF sites and VFR conditions are expected.
Breezy winds will continue especially with a strong westerly jet
over the region. Anticipate local gusts to 25-30kt overnight. Mid
level clouds will move into the region and which may flirt with some
MVFR conditions from KGEG-KCOE overnight. From 19z Tuesday through
02z Wednesday, winds will become gusty with isolated to scattered
showers especially north and east of the KGEG area.
