.KEY MESSAGES...

- Chilly temperatures with frost expected this morning. This
  includes the Moses Lake Area and Lewiston-Clarkston Valley
  which are now within their growing season. A Frost Advisory is
  in effect for the Wenatchee, Moses Lake, and Lewiston areas
  through 9 AM.

&&

.SYNOPSIS...
Frosty conditions with chilly overnight temperatures will
develop early this morning. Warm and dry conditions return for
the middle of the week. Then, an unsettled pattern comes back
at the end of the work week and into the weekend.

&&

.DISCUSSION...
As winds and cloud cover continue to decrease tonight, a chilly
morning is forecast for Tuesday, with much of the region,
including the lowlands, dropping to near or below freezing. A
Frost Advisory continues for the Moses Lake, Wenatchee, and
Lewiston areas, as well as Lower Garfield and Asotin Counties
through 9 am this morning, as these temps could impact the
beginning of the growing season in these locales.

A trend to warmer and drier conditions is then in store for the
next few days. The warmest days of the period are currently
expected to be on Thursday and Friday, when readings are
forecast to be about 4 to 10 degrees above average for most
locations. Models bring increased chances for precipitation and
cooler temps with troughing developing across the western U.S.
for late Friday into the weekend, though most solutions are
bringing the center of low pressure farther south than
previously. As such, the focus for any heavier precip will
likely be south of our forecast area as well. Something to watch
in the coming days. /KD

.AVIATION...
18Z TAFS: Weather will be quiet with widespread VFR conditions
and light winds through the 24 hr TAF period. Isolated
convective showers will be possible this afternoon.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence
in VFR conditions at TAF sites through the period. Low
confidence in convective showers impacting any TAF sites due to
their isolated nature.
