Marine Weather and Tide Forecast for Hailey, ID

DISCUSSION
Issued at 110 PM MST Fri Mar 6 2026

As our upper level trough continues to move eastward today, light snow showers in the Eastern Highlands are tapering off and mostly dry conditions will take over for the weekend. Sunshine today will help warm many of us up into the low to mid 40s for afternoon highs and help begin melting snow. Winds remain breezy at times with gusts around 20 to 30 mph. As we melt snow and release some of that moisture back into the atmosphere we will see the potential for patchy dense fog increasing tonight into Saturday morning. Models want to bring some patchy fog throughout the Snake River Plain, but confidence in overall coverage is low. Precipitation and snow totals were higher around Pocatello than Idaho Falls and Burley, but the CAMs want to bring fog into those areas, too. So, have gone with a blanket 20 percent chance of patchy dense fog through most of the Snake River Plain and eastern Magic Valley. More of the same seems likely Saturday night into Sunday as we'll do even more melting on Saturday given that highs will be a couple of degrees warmer than today.

Northwest flow aloft on Saturday will support light snow showers up in the Central Mountains and Island Park area, but any accumulation looks to remain below 2 inches with some isolated higher amounts up on mountain tops. This northwest flow transitions to zonal flow aloft during the day on Sunday and temperatures will start to climb.
In fact, Pocatello will have a 30-40 percent chance of reaching 60 degrees on Sunday while the eastern Magic Valley warms into the low 60s and the Idaho Falls areas warms into the upper 50s with about a 10 percent chance of reaching 60 degrees. With this warmer weather also comes more wind. Gusts on Sunday afternoon will be in the 25 to 35 mph range for many and Monday will be even windier with these windy conditions last all week long. Highs will remain in the 50s for most on Monday, but a cold front passing through Monday night will drop us in the 30s and 40s for Tuesday. This front will bring some precipitation chances with it, but looks confined to the higher elevations for the most part at this time. Warming will get back underway on Wednesday afternoon as the gusty winds continue.

Skies have finally improved to solid VFR for the afternoon and overnight. An upper level feature arrives around 07/13Z plus or minus an hour that spreads mid-level moisture at first along with a return to south to southwest wind, then lower level moisture for Sat afternoon. There is a threat of some marginal VFR after 07/18Z for KIDA, KBYI, and KDIJ. KSUN too far north and KPIH receives some downslope component to prevent the CIG development. This mid-level cloudiness appears to arrive early enough to prevent any low level stratus or BR/FG during Sat morning to affect VSBY.

Except for KDIJ, wind actually stays up to help in the prevention for stratus and BR/FG as well. Elevated wind to around 15KT develops everywhere by late morning except the sheltered KSUN.
