Area Forecast Discussion
National Weather Service Spokane WA
1047 AM PDT THU MAR 26 2015

.SYNOPSIS...
Lingering showers will continue over the northeast mountains and
Idaho Panhandle today...with partly sunny skies and warming
temperatures elsewhere. Friday through the weekend will be much
warmer than average with afternoon temperatures in the 60s and
even some lower 70s down in the Columbia Basin. Precipitation
chances will be tied to two cold front passages. The first arrives
Friday night and a second Monday night or Tuesday. Gusty winds
will accompany each front.

&&

.DISCUSSION...
Rest of today: We`ve made a few minor changes to the fcst, which
includes sky cover, winds and high temps. We increased the mid to
high cloud areal coverage based on satellite and obs trends...
though these clouds are not thick and are should allow filtered
sun for most zones south of a line from Spokane to Moses Lake the
next few hours. NE Wa and the Idaho Panhandle will hold on to mostly
cloudy conditions well into the afternoon. These thick clouds are
tied to what may be a lee Cascade wave... and isentropic ascent
along a slowly N moving warm front. Only light amnts of rain will
fall...mainly in the mtns for these areas, decreasing during the
day as the front moves N.

The next wx focus we`ll be working on are near record high temps
for Fri...winds on Sat (and especially Tues). Slow levels will
fall beginning Tues Nt, with possible pass-level snows. bz

.AVIATION...
18Z TAFS: With the upper level ridge amplifying over the Pac Nw,
expect VFR conditions for all TAF sites... though there still
remains patches of IFR ceilings near KEPH that are quickly
dissipating and should be gone by 20z. Opaque ceilings ranging
from 15-20k ft agl are still widespread across NE Wa and the N Id
Panhandle... overlaying patches of MVFR stratus in the valleys.
These lower cloud decks may take closer to 22-23z to lift to VFR.
