Summary

An unsettled pattern will take shape this weekend. Expect cooler weather through next week with periods of valley rain and snowfall above about 6,000 feet. An inch or so of accumulation each day is expected in the high country with showers in the lowlands. Mountain temperatures are already near freezing each night now, but next week we will see readings dropping down into the 20’s. High temperatures will only reach the mid 40’s which is about 10 degrees below normal.

Today

This will be the warmest day for quite a while with the last bites of high-pressure overhead. By tonight, this will give way as a cold front nudges in from the west with breezy winds and showers pushing through. Here’s how the pattern looks from space. Notice the moisture band stretching along the Pacific Coastline (in Blue colors)? That’s what is headed our way, with the main upper-level storm system further west (in Black colors)

Saturday through Thursday, October 5

A cold front will push through the state tomorrow ushering in a low-pressure system from the Pacific Northwest. This will bring a pattern of cool and moist weather that should persist at least through mid-week. Temperatures will be below seasonal normals for the beginning of October. That means a re-charge of the soil with several days of light precipitation. Long duration, light rain, and snow are far more beneficial than heavy storms that pass through.

Here’s a preview of how much accumulation is expected with the Idaho Central Mountains getting half an inch to an inch (in Blue colors):

Extended Forecast

Early October

NOAA’s Climate Prediction Center is telling us some good news for the first half of October in their 8 to 14-day Outlook.  We’re poised to see cooler and wetter weather heading into fall. You’ll notice that this is different than what was posted last week for the monthly outlook, which just goes to show you how dynamic this transitional season is. Forecasting long-term weather during the switch from summer to winter is uncertain at best.
