Area Forecast Discussion
National Weather Service Spokane WA
1052 AM PDT Mon Jun 26 2017

.SYNOPSIS...
Afternoon temperatures will climb into the 90s once again today.
Warm temperatures will fuel scattered thunderstorms late this
afternoon and this evening. Some storms may produce strong winds
and frequent lightning. Temperatures Tuesday, Wednesday and
Thursday will be close to average before warmer conditions return
Friday and Saturday.

.DISCUSSION...
An area of clouds and sprinkles is currently moving across the
forecast area, but should be exiting soon. Skies have already
cleared in the lower Columbia Basin where temperatures have
already reached the 90F mark in Pasco. More importantly, the
sprinkles have helped to moisten the atmosphere, such that surface
dew points are all in the 50-55F range, which is fairly decent for
this area. Those dew points will likely low some with afternoon
mixing, but they still could play a role in the convective
potential for this afternoon/evening.

Satellite shows elevated convection developing over southeast
Oregon at the moment, heading north. The CAM models all show this,
but in the early afternoon. Remains to be seen if this is just a
timing error, or if there will be bigger implications. In any
event, the expectation is that convection over Oregon will
continue to increase, eventually reaching northeast Oregon and
southeast Washington late this afternoon. Strong gust fronts are
possible, and could reach the Spokane area this evening. After
this, the CAMs are expecting more convection to fire south of
Spokane along a cold frontal boundary.  RJ

.AVIATION...
18Z TAFS: Thunderstorms will affect many of the TAF sites this
evening. The storms will move into the area from the south, and
gusty winds could impact the airports. Confidence of the storms is
high enough to put in the TAFs, but the exact timing of the storms
and winds could easily be off by an hour or two. RJ

.FIRE WEATHER...
A Red Flag Warning was issued for the Wenatchee area (WAZ677) for
the combination of winds and low humidities for this afternoon and
this evening. Neighboring zones of the Kittitas Valley and
Columbia Basin could also see Red Flag conditions, but the
humidities are not expected to be as low.  RJ
