Area Forecast Discussion
National Weather Service Spokane WA
441 PM PDT FRI MAY 16 2014

.SYNOPSIS...
High pressure will continue to break down through Saturday, while
low pressure migrates Inland for Sunday and early next week.
Disturbances rounding the low will bring shower and thunderstorm
chances to northern Washington and the Northern Panhandle of Idaho
through Saturday. The weather will remain unsettled through the
first part of next week, with showers and a threat of
thunderstorms, and cooler temperatures. The shower threat wanes
and temperatures moderate towards the middle of next week.

&&

.DISCUSSION...
Tonight: A weather disturbance will continue to track across
northern WA and north ID this evening and tonight. Showers and
thunderstorms have started to develop as of 2 pm across northern
WA. They will continue to develop and become more widespread
through the late afternoon hours. Models hold on to some decent
instability through the evening hours and so keep thunder across
northeast WA and north ID through 10 pm. Was contemplating putting
in thunder during the overnight hours, but there is quite a bit of
convective inhibition that moves into the area overnight. So, took
out thunder for the overnight hours, but still have at least a
chance of showers through the overnight hours into early Saturday
morning. Models seem to be hitting the Okanogan Mountains as well
as the north ID Panhandle (Bonner and Boundary Counties) pretty
hard with the qpf. A wetting rain from showers and thunderstorms
is quite possible across the north tonight. The rest of the
forecast area...mainly south of a line from Lake Chelan to Spokane
to Saint Maries has quite a bit of dry air infiltrating the area.
They should remain dry this evening with just thick overcast high
clouds. South to west winds will also be an issue this evening. 10
to 15 mph will be common south of a line from the Waterville
Plateau to Spokane. The strongest winds will be around the
Wenatchee area where west winds 20 mph with gusts up to 30 mph
will be possible this evening. Winds will decrease overnight, but
still in the 5 to 10 mph range. The thick overcast cirrus skies
will start to thin towards morning. Temperatures tonight will be
about 5 degrees above average for this time of the year. /Nisbet

Saturday through Monday...A large area of low pressure continues
to influence the forecast area through this time interval. Minor
shortwave disturbance rotating in and long the edges of this large
low have the ability to utilize the cool yet conditionally
unstable airmass contained in the low along with a reasonable
amount of low level moisture to keep a prolonged mention of
showers and perhaps even some thunderstorms in various shape
and/or form. At one time forecast max temperatures looked to
bottom out on Sunday but they now seem to be equally cold for
Monday per latest guidance with forecast temperatures roughly near
5 degrees or so on the cool side of what would be considered
normal for this time of year for Sunday and Monday. /Pelatti

Monday night through Friday...A flat upper ridge will provide a
warming and drying trend through Thursday. However residual
moisture and instability could produce afternoon/evening
convection in the form of mainly showers on Tuesday with this
threat becoming confined to the Idaho Panhandle on Wednesday. On
Friday the ridge will get pushed east as an upper level wave
passes through the region. Models are not very strong with this
but a combination of increased lapse rates and lift could trigger
showers especially over the mountains. JW

&&

.AVIATION...
00z TAFS: An offshore low will send impulses across the Inland
NW. The threat of showers and thunderstorms will continue this
evening with showers lingering overnight. The higher focus will
be across the northern third of Washington and the northern
panhandle of Idaho. Though there are some chances that KGEG to
KCOE may have some thunder, confidence is not high enough to put
-TSRA in TAFs. Overall VFR conditions are expected, but local MVFR
conditions are possible should a heavier shower pass a TAF site.
The incoming impulse will also bring some breezy conditions this
afternoon. KEAT is expected to be impacted the most with gusts to
30 kts this evening. Scattered showers and isolated thunderstorms
will be possible Saturday afternoon, again focused on northeast WA
and the northern panhandle of ID. /EK
