Area Forecast Discussion
National Weather Service Spokane WA
935 PM PST FRI FEB 12 2016

.SYNOPSIS...
A cold front will pass through the region tonight with continued
precipitation chances and slightly lower snow levels. Unsettled
weather will continue through the weekend into early next week
with valley rain, high mountain snow and breezy winds expected.
Temperatures will be quite mild on Monday with many locations
seeing highs in the mid 50s to low 60s. Near record high
temperatures are possible.

.DISCUSSION...
Numerous updates to the forecast included some mention of
thunderstorms near the blue mountains as the cold front filled in
quite nicely and intensified. Cloud top temeratures in the -45 to
-50 range show infer some good vertical extent to the convection
in the conditionally unstable airmass along the edge and behind
the cold front. The radar reflectivities for the most part have
been on the decreasing trend in the Spokane area as the showers
move away from the radar while the cloud top temperatures remain
a bit more steady and cool which leads me to believe that the
radar is overshooting the more intense rainfall and some of it is
likely bright banding where wet snow is melting down at the lower
levels on the order of 7000 feet MSL or so. Other stuff added with
earlier updates included more mention of fog and low clouds for
overnight and Saturday morning as the winds are not expected to
pick up until tomorrow morning. /Pelatti

.AVIATION...
06Z TAFS: Cold front spreading showers, with some thunderstorms in
Northeast Oregon, tonight from west to east. Most of the activity
should be out of the aviation area by 9Z tonight. Some low clouds
and fog to linger in the lowlands and basin overnight and early
Saturday morning and then southwest winds will increase and become
gusty later Saturday morning and help erode it all. More spotty
showers may linger between weather disturbances until yet another
weather disturbance spreads more rainfall from west to east
through the aviation area as early as 22Z for KEAT and beginning
as late as 01Z Sunday for KGEG and 3Z Sunday for KPUW. /Pelatti
