A high pressure system will make for dry and warm weather conditions on Sunday. However, on Sunday night, a dry cold front will move into the region, causing highs for Monday to significantly drop. Sunday night winds will pick up and places across the Snake River Plain could see wind gusts get up into the 20’s. Temperatures on Tuesday will mostly stay in the upper 40’s and into the 50’s. There should not be a lot of active weather on Halloween night.
