MAGIC VALLEY (KMVT/KSVT) Strong Pacific storm system will push a cold front through Southern Idaho Thursday morning. This front will bring strong, potentially damaging wind gusts to the Magic Valley Thursday morning and continue through Thursday afternoon and evening.
High wind warnings have been posted for the western Magic Valley from 9 a.m. Thursday until midnight Friday and a wind advisory for the same time for the Mini-Cassia region. Sustain winds will be out of the west to southwest during the day and reach 30 to 45 mph. Potential wind gusts of 60 to 70 mph could occur Thursday morning between 8 a.m. and noon as the front pushes through with afternoon wind gusts between 50 and 60 mph.
The main threat with wind will be high profile vehicles like semis and tractor trailers on north-south oriented roads and highways. Motorist who cross the Perrine and Hansen bridges should be prepared for gusty winds. Wind storms that produce 60 mph winds can accelerate through the canyon and tip over high profile vehicles like it did March 17, 2014. Also some minor property damage is possible along with branches breaking and small trees uprooted.
We won’t just have the wind but some rain and possible thunderstorms are possible with this system. Storms could potentially be severe due to the wind and rain amounts could range between a half an inch to near an inch depending on where the heaviest of rain falls. Rain could change and mix with snow during the afternoon as temperatures fall from the 40s in the morning to the middle 30s by the afternoon. Snow is not expected to stick to the valley floor as temperatures are and have been too warm.
