Area Forecast Discussion
National Weather Service Spokane WA
945 AM PST TUE FEB 9 2016

.SYNOPSIS...
Strong high pressure will persist into Wednesday. Dry and mild
conditions are expected for the first half of the week. A more
progressive and unsettled pattern will return late this week
bringing a chance of light rain Thursday in the Cascades and over
the rest of the region Friday through the weekend.

.DISCUSSION...
Only some minor updates to the fog forecast has been made based
off of the visible satellite imagery this morning. The fog is very
shallow, but morning inversions are also very strong. It will take
at least a couple more hours before the fog burns off and may not
completely until mid afternoon for the northern valleys. May need
to make additional forecast updates with high temperatures today.
The morning sounding at Spokane shows 850 mb temps of 6.8 Celsius,
which is about 3-4 Celsius warmer than 24 hours prior. It is
difficult to say how much of this warming will translate down
into the valleys considering the strength of the inversion. The
southeast portion of the forecast area will see the best chance
for some very mild temperatures in the mid to upper 50s and
possibly some 60s. Similar type of temperatures will also be
possible above the inversion at mid and upper slopes. /SVH

.AVIATION...
18Z TAFS: Visible satellite has revealed that much of the fog is
confined to the mountain valleys. There is still a bit too much
mixing for low clouds to develop across the interior basin. An
hour or two of low clouds will be possible at KCOE before burning
off between 19-20Z this morning. Fog may not fully burn off across
the northern valleys until mid afternoon. VFR conditions are
expected to prevail at all TAF sites through the afternoon and
into the evening. With a stronger inversion in place, there will
be a better chance for a bit more widespread fog to form overnight
tonight into Wednesday morning. All TAF sites except for KPUW and
KLWS will see at least a chance for some fog developing overnight
into Wednesday morning. /SVH
