Area Forecast Discussion
National Weather Service Spokane WA
430 PM PDT Wed Jun 28 2017

.SYNOPSIS...
Showers and isolated thunderstorms will move across Northeast
Washington and the Idaho Panhandle this evening. Beginning
Thursday, the weather will be dry and mild through the remainder of
the week. The weekend will see continued dry weather but warmer
temperatures. Monday and Tuesday have the potential to be dry and
breezy raising concerns for grass fires heading into July Fourth.

.DISCUSSION...
Tonight through Friday: Showers and thunderstorms are developing
on schedule over the northern mountains. This activity is expected
to continue to increase. A weather disturbance coming down from BC
will provide support for these storms and help them to move
southward into the eastern Columbia Basin and the rest of the
Panhandle. Again, due to lack of shear, these storms should not be
strong. Gusty winds and small hail will be the biggest impacts
from them. Northwest winds in the lee of the Cascades will blow
all night.

For Thursday, much quieter weather is on tap. Only isolated
mountain showers are expected, and with very weak winds aloft,
these showers won`t go anywhere. Meanwhile, the winds will
decrease significantly. Friday will see temperatures warm about 5
degrees under sunny skies.  RJ

Saturday through Wednesday: The main impacts for this period will be
mainly the dry and windy conditions across the basin and some
isolated thunderstorms along the Canadian border over the
weekend.

Saturday and Sunday: A dry shortwave trof will push the region on
Saturday will break down the ridge and bring increased winds
across the basin for the afternoon with gusts in the upper 20s
mainly in the Leeside of the Cascades and Waterville Plateau.
Winds will decrease slightly on the Sunday but still be breezy.

Monday through Wednesday: A stronger trof will push the region on
Monday and bring bring another round of breezy winds for the
Columbia Basin strongest winds will along the Cascades with gust
potential into the low 30s. The rest of the basin can expect some
winds in the range of the mid 20s.

Temperatures for this period will be in the range of 80s to low
90s for highs and in the 50s for lows. /JDC

.AVIATION...
00Z TAFS: Showers and thunderstorms will continue to develop this
evening over the northern mountains and move to the southeast.
This could impact the KGEG/KSFF/KCOE terminals, most likely KCOE,
with gusty winds and pea-sized hail. To the south, KPUW and KLWS
could see the remnants of these showers later this evening.
There`s an outside chance of an MVFR cig at KPUW Thursday morning.
Only enough confidence to put a Scattered deck in the TAF at this
point. KMWH and KEAT will remain VFR with gusty winds this
evening, diminishing overnight. The winds at KMWH should keep the
wildfire smoke to the south. But on Thursday, a wind shift to the
southeast could bring smoke into KEAT in the afternoon. RJ

.FIRE WEATHER...
Red Flag warning remains in effect until 8pm for the Wenatchee
area due to Wind/RH combination. Winds will continue to blow all
night in exposed areas but humidity levels should rise into the
40-50% range overnight. Winds will decrease Thursday morning and
remain light through Friday. For the weekend expect afternoon
evening winds to increase a bit. A dry cold will bring breezy
winds to the area on Monday.  RJ
