It’s the coldest Halloween in at least three years and there are plenty of clouds holding our temperatures down.
We’re hopeful that Sioux Falls and Aberdeen will see some late-afternoon clearing but that patch of blue sky is fairly narrow. Winds are on the gusty side, too, into the mid 30s in central South Dakota. Gusts are closer to 40 mph in western South Dakota. We’ve got nearly-overcast skies in the forecast for Thursday evening.
If you’re heading out for trick-or-treating Thursday night, you’ll want to dress accordingly. We’ll be in the low 40s in Sioux Falls and down to the upper 30s elsewhere. A small, moisture starved system is already crossing NW South Dakota. A few sprinkles are possible, but the air is pretty dry in the west. Some mist is also possible, but we’re not expecting anything heavy anywhere. That slim chance of light sprinkles moves east by Friday morning. Winds will be the main story of the day, though. Sustained NW winds of 25-50 are likely out west, and those in Sioux Falls and Aberdeen won’t be far behind.
Some sunshine returns this weekend and it will be the warmest time of the coming week. A powerful cold front comes by Monday, dropping our highs by 10-20 degrees in the west. There’s a chance of wintry mix on Tuesday. It’s far off but the best moisture looks like it could set up in the southeast.
