Exclusive Summaries & Forecasts For
The Inland Northwest
By Climatologist Bob Lutz
Inland Northwest Summary Issued:
Short-Term Weather Model Agreement for the Pacific Northwest is:
(POOR= Forecast Changes are Likely * GOOD= Fair Agreement, but Changes are Possible * EXCELLENT= Changes Unlikely)
"Saving Lives through Education"
The first weak wave will keep a chance of showers in the forecast through Tuesday. The best chance of more widespread rain
with this first system will be in the southern and eastern zones.
agreement is coming into much better alignment on a rather wet period ahead! Strong high pressure will set up
to our southeast allowing a moist southwesterly flow to develop over the Northwest. This will be enhanced
by a powerful storm in the Gulf of Alaska which is absorbing some of its moisture from the remnants of a
couple of tropical systems out in the Central Pacific. The result will be periods of rain, some moderate at times
beginning around mid week. Much heavier amounts are expected in the mountains. The systems will also bring
with them occasionally gusty winds and cooler temperatures. The models diverge a bit for the upcoming weekend with some
forecasting a continuation of wet weather, while others indicate a drying trend as the ridge to our south temporarily noses
into the Northwest. As such, the weekend outlook is a tough call right now.
No hazardous weather is expected through Tuesday for the western zones. Showers will increase for the southern and eastern
Zones Monday night and Tuesday. Periods of moderate rain and gusty winds will increase in all areas Wednesday & Thursday.
