Area Forecast Discussion

.SYNOPSIS...
High pressure will build over the Pacific Northwest Thursday
bringing an extended period of very warm and dry weather to the
region through the middle of next week.
&&
.DISCUSSION...
Today through next Wednesday: The main message is a welcomed
warming trend late this week for the Inland Northwest. Models
indicate a rex block taking shape through tomorrow and into the
weekend with high pressure dominating the Inland Northwest.
There will be plentiful sunshine and weak winds through at least
next Monday. Temperatures tomorrow will be in the 50s as the
ridge establishes itself. By Friday, temperatures will warm into
the low 60s in spots. By Saturday, the L-C valley, basin, and
Wenatchee/Okanogan valleys have a 40-60% chance of hitting 70
degrees or higher. By Sunday and Monday, those probabilities
increase to as high as 90% in the L-C valley and
Wenatchee/Okanogan valleys. Downtown Spokane has a 20% chance of
hitting 70 degrees Sunday and Monday.
An active subtropical/polar jet will begin to disrupt the rex
block around Tuesday of next week which brings back precipitation
chances to our area and cooler temperatures. /Butler

at KEAT/KMWH/KGEG/KLWS. VFR conditions are preferred at
KCOE/KSFF/KPUW although there is a 10-20% chance of fog impacting
these TAF sites between 11z-15z. JW
