Marine Weather and Tide Forecast for Hailey, ID

DISCUSSION
Issued at 301 AM MDT Fri Apr 10 2026

Daytime temperatures today will run very similar to, if not a few degrees warmer than, yesterday's temperatures. Widespread low elevation areas will observe low to mid-70s, which is 15 to 20 degrees above climatological normal. The limiting factor will be the increased cloud cover, which could inhibit daytime heating more than accounted for in the forecast. Moisture associated with the low off the OR/CA coast will continue to lift into Idaho in southwest flow aloft with the system eventually working through Idaho, meaning chance of precipitation and thunderstorms will increase in both probability and areal coverage as we head further into the weekend.
Probability of isolated thunder will roughly range 15 to 30 percent over the course of the weekend. 700mb winds will increase beginning tonight, with the National Blend indicating max surface wind gusts ranging 35 to 45 mph both Saturday and Sunday with breezy to windy conditions persisting into the early part of next week. In additional to cooler temperatures Saturday, the weekend cold front will result in seasonable temperatures beginning Sunday, becoming slightly cooler than normal early next work week. Storm total liquid precipitation through Tuesday ranges 0.30" to 0.40" across the Snake River Plain with around a quarter of an inch to half an inch in the southern highlands and eastern mountains, and half an inch to one inch in the central mountains. While snow levels will initially be very high, they will drop to 7,000 feet by late Sunday behind the cold front. Storm total snow amounts generally range 2 to 6 inches above 7,000 feet with locally higher totals in the highest elevations. Flow aloft looks to briefly turn zonal mid-week in the wake of the departing system and ahead of the next low descending from Canada. Models are still sorting out the upper-level details, but the pattern looks to remain active for the latter half of next week, as well.
