Area Forecast Discussion
National Weather Service Spokane WA
945 PM PDT Wed Mar 13 2024

.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

.AVIATION...
06Z TAFS: VFR conditions are forecast for the region into
Thursday for the main airports with light winds and passing high
clouds. Some of the smaller airports in the ID Panhandle will be
subject to patchy fog through 15z with satellite showing fog in
many of the valleys of the Central Panhandle as of 0430z. HREF
shows around a 10-20% chance of some of this fog expanding into
KCOE and KPUW but given low confidence kept conditions VFR.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
There is high confidence for VFR conditions through the TAF period
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
