Area Forecast Discussion
National Weather Service Spokane WA
801 AM PDT Fri May 5 2017

.SYNOPSIS...
A slow moving frontal system will be the focus for showers and
thunderstorms today. Some storms will be capable of producing
locally heavy rain, frequent lightning, and possibly hail and
gusty winds. Saturday will be cooler with showers lingering over
the Idaho Panhandle and far eastern Washington. Monday and Tuesday
will have the best chance of being dry next week. Unsettled
weather will likely return by Wednesday or Thursday.

&&

.DISCUSSION...
Forecast has been updated based on radar trends. Radar shows two
areas of convection as of 745 am. The first is from Republic to
Keller south towards the Tri-Cities area associated with the cold
front associated with the incoming trough. The second is ahead of
the front from the Camas Prairie into the Idaho Panhandle. There
is sufficient mid level instability to kick off isolated
thunderstorms in these two areas except locally scattered storms
in the Okanogan Highlands where models are showing higher most
unstable CAPE values of 400-700 J/KG with radar confirming this
with a few more intense cells in the area. Further west towards
the Cascades more stabilization has taken place behind the front
and thunderstorms were removed for the morning. This afternoon
look for a general increase in thunderstorms mainly north and east
of a line from Winthrop to Ritzville. Localized debris flows from
heavy rain on saturated soils in the northern mountains are
possible. A few strong to isolated severe storms are also
possible.  JW

&&

.AVIATION...
12Z TAFS: A cold front will be making its way into the area today,
working with abundant moisture and instability. This will lead to
an increasing shower and thunderstorm threat across the region.
The activity should mainly isolated in nature early this morning,
but will increase in coverage late this morning and afternoon,
especially around GEG/SFF/COE/PUW/LWS. Some of the storms may be
strong with heavy downpours, gusty winds and hail. The heavy rain
may produce localized reductions in visibility. Confidence in the
timing of individual thunderstorms is lower, so radar will
continue to be monitored and TAFs will be updated to alert of more
imminent thunderstorms. The threat of thunderstorms wanes after
01-03Z, but showers will remain a threat in the eastern TAF sites
through tonight. In addition to precipitation, winds will increase
between late morning and afternoon with gusts of 20-30kts
possible, before the abate toward 01-03Z. /J. Cote'
