DISCUSSION

Today through Fri night...Wind strength and temperatures are down compared to yesterday as eastern Idaho sits between the exiting cold front and an approaching coastal low currently sitting off the OR-CA coast. This upper level low will dig southeastward. As it gets closer to the coast and finally moves onshore, the precipitation through from unstable moisture moving in from the south begins. On Thu, very little is expected, and mostly stays south of Pocatello, except for a light shower threat in the central Idaho mountains. By Fri afternoon the threat gets to chance probability or more everywhere except the southeast corner of the state, where it is slight chance-level.

Starting Thu, temperatures start to warm in spite of the increasing cloud cover, as the southerly flow brings in the warmer, moist air. Expecting lower to middle 70s in the Snake River plain for Fri afternoon. Similar warming trend to overnight lows starts Thu night.

Wind continues windy today, just below Wind Advisory thresholds for some. Breezy or windy conditions continue for the afternoons on both Thu and Fri, though not as strong as today.

Sat through Tue...Around 80 to 85 percent of the ensemble solutions show this upper level low moving onshore and in a position to drop some pretty good precipitation amounts in eastern Idaho, with the remainder keeping this low farther south and less likely to bring precipitation. The low starts moving away on Mon, then has cleared to the east by Tue afternoon. Currently the wettest day (most likely to bring rain) is Sun.

Temperatures cool to near normal by Sun as well, and overnight lows with the cloud cover stay above normal. Afternoon highs start warming again on Tue.

Wind stays elevated and should be fairly windy each afternoon on the weekend, though at this time appears to be below Wind Advisory thresholds. This leads into the 8 to 14 day forecast which has above normal precipitation and temperatures.
