Areal Flood Warning 2, NWS Spokane, WA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1121 AM PST Tue Feb 11 2014

.SYNOPSIS...
Another storm system will bring light to moderate precipitation to
the forecast area tonight and Wednesday. expect rain across the
south and snow across the north. More storms will track through
the region during the week. Each will deliver periods of
precipitation...mainly rain in the valleys and snow in the mountains.

&&

.DISCUSSION...
Currently we are in a break between weather disturbances. The
moisture associated with the exiting storm has finally moved out
of the region and the remaining Winter Weather Advisories were
ended. Stratus and areas of fog have developed through the morning
across all of the northern valleys and spilling south into the
Basin...Wenatchee Valley...Spokane area and portions of the
Palouse. As such fog and a bit more cloud cover was added to the
forecast. Areas in the stratus and fog will not make it to
forecasted highs and these temps were cooled off by a few degrees.

For tonight and Wednesday the next storm system will move into the
region and this storm will be a bit stronger than the last. Good
southerly flow will allow snow levels to begin to rise across the
southern zones. Not so confident that the northern mountain
valleys will see snow levels rise as quick as previous thinking
and highlights for the valleys may need to be added. A little
tougher call in areas that have stratus and fog as cooler
temperatures will most likely allow precipitation to begin as snow
or snow/rain mix before changing over to all snow. Also it looks
like the Waterville Plateau...Wenatchee Valley and part of the
northern basin may see some freezing rain early Wednesday morning.
Highlights will be updated with the afternoon package. Beyond that
conditions warm up enough for lower elevation rains and mountain
snow. /Tobin

.AVIATION...
18Z TAFS: The forecast area is currently in between weather
systems. Some fog/stratus development has occurred behind the
exiting weather system...but is trying hard to mix out per
satellite imagery. As such expect widely variable conditions at
most TAF site through the afternoon as fog/stratus clears and
reforms. The biggest challenge will be the KGEG-KCOE corridor
where the stratus is expected to mix up and rebuild through the
afternoon. As such expect anywhere from VFR to MVFR at times and
possibly IFR on occasion. Otherwise TAF sites will be mainly VFR
through 00z. Moisture is quickly moving in from the west as the
next storm system is expected across the Cascades by this evening
and move across the forecast area through the night. Expect
precip at the KEAT/KMWH to start as snow but change over to rain
...with the possibility of an hour or so of freezing rain around
06z with IFR/LIFR conditions through the night. KGEG-KCOE will
begin as snow after 03z and turn to rain 06z-08z again with
IFR/LIFR cigs/vsby. For KPUW/KLWS precipitation as rain through
the night with MVFR conditions. /Tobin
