.SYNOPSIS...
The main threat for showers today will be in the Idaho Panhandle,
otherwise drier and warmer conditions are expected. A disturbance
on Monday will bring another round of showers and thunderstorms
for the afternoon and evening hours. A warmup is expected
Wednesday and Thursday with widespread high temperatures climbing
up into the 70s. A return to cool and unsettled conditions for
next weekend.

.DISCUSSION...

Valley fog has burned off. We`ll see a lot of fair weather cumulus
developing over the region into the afternoon, especially over
extreme eastern Washington and the Idaho where rain fell
yesterday. The higher terrain will see the potential for a light
rain shower today. Maybe get a bit of a sprinkle down in the
valleys as these showers drift off of the mountains. /SVH

.AVIATION...
18Z TAFS: Fair weather cumulus will build into this afternoon with
cloud bases starting out between 3-4 kft. late this morning and
lifting to around 5-7 kft. by mid afternoon. Tops of cumulus will
reach up to around 14-17 kft. into the early afternoon, and may
see light showers, or virga, fall from the base. Temperatures
aloft will be warming with a shortwave ridge moving in, and this
will lower the equilibrium levels of rising air parcels resulting
in a progressively more stable atmosphere by late the afternoon
hours. A shortwave disturbance will move into the Inland Northwest by
Monday morning. Mid to high level clouds will increase ahead of this
wave for the morning with light showers or sprinkles possible.
Deeper layer instability will follow for Monday afternoon with
thunderstorms possible that will be capable of dime sized hail,
wind gusts to around 30 kts, and brief heavy rain. /SVH
