Gusty Winds Wednesday

Low pressure moving in will bring periodic showers and a chance for t-storms Wednesday and Thursday, along with breezy to windy conditions. The best chance for t-storms will be in the mountains and southeast WA/lower ID. Winds will be strongest over the central WA and could result in patchy blowing dust. Cooler temperatures come in too, which could mean some patchy frost by Thursday night into Friday morning in some sheltered valleys.

Winds will increase from the south Wednesday afternoon into the early evening. The strongest winds are expected across the Columbia Basin, Waterville Plateau, and Okanogan Valley. Main impacts will be strong crosswinds on west-east highways, reduced visibility from blowing dust, and chopping lakes. This will also blow around any unsecured lightweight items. Use caution is driving across eastern Washington tomorrow!
