.DISCUSSION...
Morning update sent expire winter weather advisories for
southeastern WA and the lower Idaho Panhandle. Cams indicate on
and off light snow in these areas but accumulations will be light
having little additional impacts to travel. We did delay snow
departing the Camas Prairie until later this evening when the
inverted surface trof finally weakens and weak omegas decrease.

Outside these southeastern zones, it will be a sunny dry day with
accompanied by chilly temperatures with afternoon highs only
warming into the 20s. Tonight will be very cold. We will utilizing
the morning lows for Monday and likely adjusting readings near to
colder. Many of the northern mountain valleys dipped between -2
and -10 F this morning. The only caveat for Tuesday morning will
be a few clouds developing 3-4K ft AGL. Timing looks around 9-12z
so thinking many locations will dip toward their respective lows
before these may have any influence. May be a case where the
lowest temperature occur before sunrise. In reality, whether it is
-5F or +5F, it will be very cold for your Tuesday morning. Good
 news is there will be little to no wind. /sb
