.UPDATED AVIATION DISCUSSION...

.AVIATION...12Z TAFS...VFR conditions will prevail through the TAF
period for all sites with light winds. However, KYKM could see fog
redevelop within the overnight hours hence potentially dropping VSBY
to 1SM or lower (<30% confidence). Feaster/97

.PREV DISCUSSION... /issued 147 AM PST Wed Jan 14 2026/

DISCUSSION...High pressure will be the dominant feature over the
region for the foreseeable future. This will make valley/Basin fog
and air stagnation the main areas of concern over the next week.
While the ridging prevailing over the PacNW will occasionally be
flattened or shifted by shortwaves well to our north, ensemble
guidance is in pretty strong agreement (70-80% forecast confidence)
that some form of ridging will be centered over or just offshore
from the PacNW.

Tonight, dense fog is socked in over the Kittitas Valley, where an
Advisory is in effect until midday Wednesday. Satellite imagery
overnight shows isolated pockets of fog developing in the lower
Yakima Valley as well. Generally the atmosphere needs a day to
`prime` itself for fog, before it becomes more widespread by day 2.
Was a little more conservative with overnight fog coverage through
Wednesday morning as a result, outside of a small window around
sunrise, before drawing a more widespread area of fog in the
forecast overnight heading into Thursday morning. Coverage includes
the usual fog-prone areas in the lower Columbia Basin, spreading
into adjacent valleys.

Otherwise, high pressure will continue to support air stagnation
across the forecast area this week. Global deterministic models
suggest that the ridge flattens out during the day Thursday, before
building back in just offshore heading into the weekend, with cold
northerly flow ahead of it eating into our ongoing mild
temperatures. Should a stratus deck settle in the Basin over the
weekend, however, temperatures shouldn`t bottom out too much outside
of the elevated valleys, which could see 20s and even teens over the
weekend into early next week (30-40% confidence). 74
