Area Forecast Discussion

1054 PM PDT MON SEP 22 2014

.SYNOPSIS...
Warm temperatures are expected again on Tuesday, but fall type
weather is on the way for the end of the week. A slow moving cold
front will bring good chances for rain to central Washington on
Wednesday and Thursday. Cooler temperatures will also accompany
the cold front Thursday and Friday. A slight warming and drying
trend is expected to occur next weekend.

.DISCUSSION...
Evening update: minor changes to overnight lows over the Basin.
Newest guidance shows cooler temperatures here and 24 hour trends
suggest we may have been a bit too mild. So I trimmed 1-3 degrees
off of lows in isolated spots like OMK/MWH. Much of the immediate
showers are now over southeast WA, with more isolated activity
across the remainder of the region. However additional activity is
developing around Portland and spreading northeast, with
additional development expected. In addition the aforementioned
southeast WA precipitation is also projected to expand north-
northeastward. So by later overnight (09Z) and Tuesday morning
many areas could be wet. How quickly this shifts north before
additional activity develops from the west and/or south in the
afternoon is uncertain. However we are definitely moving into a
wetter pattern.

.AVIATION...
06Z TAFS: A couple weather disturbances pass through the Inland
NW over the next 24 hours. The 1st weather disturbance with a
broader shower threat comes in between late evening and Tuesday
morning, with scattered to locally numerous showers possible at
all TAF sites. A brief lull is expected in the mid to late
morning, before the second disturbance approaches in the afternoon
and keeps the threat of showers alive. VFR conditions are
projected, but lcl MVFR conditions possible in any heavier
showers. /J. Cote`
