Marine Weather and Tide Forecast for Bellevue, ID

DISCUSSION
Issued at 1031 AM MDT Wed May 13 2026

An active weather day is under way. As low pressure approaches from the west, we are seeing increasing winds already and will continue into this evening even behind the front. Outside of storms, we are expecting gusts in some cases up to 55 mph. With thunderstorms gusts in excess of 60 mph are likely with gusts over 65 mph possible. Storms should clear by late evening along with stronger wind subsiding. Otherwise, we remain dry until the weekend.
Today is the last widespread WELL ABOVE AVERAGE temperature day we will see for a bit. Ahead of the front, especially where downslope is occurring, we are still looking at potentially hitting 90 degrees. We drop to right around AVERAGE for this part of May, before dropping BELOW AVERAGE over the weekend and early next week.
Sunday still looks like the coldest day, especially if we can get a deeper low in place, highs are in the 40s and 50s areawide.
Overnight lows and more frost/freeze issues are expected to return.
We may see some pockets of frost and light freeze until Saturday morning. Beyond that, several morning of widespread frost and freeze conditions are likely. Monday and Tuesday mornings will be the coldest based on the latest trends in the Blend of Models. We are looking at widespread 20s for overnight lows across portions of the Snake Plain and Magic Valley, with the more populated cities barely hitting freezing.

Issued at 614 PM MDT Wed May 13 2026

A strong cold front has moved through most of the TAF sites.
There is a slight chance of vicinity thunderstorms for PIH and DIJ for the next hour. Winds did drop off slightly with the cold front having moved through. However, strong westerly and northwesterly winds well behind the cold front are now moving in from the west. These stronger winds have already moved over SUN and BYI and winds are starting to drop off from the initial strong onset for SUN and BYI. These strong winds will move over PIH in next 30 minutes and move over IDA in the next hour (and later for DIJ but weakening). Winds will remain elevated for DIJ as well. CIGS will clear out in the next couple of hours as the strong westerly and northwesterly winds are also bringing clear skies. Winds will gradually drop off to 10 to 15 kts after midnight. Then winds will pick up by mid morning into early afternoon with gusts of 20 to 25kts for all TAF sites.
