Now that we’ve rolled back the clocks, today’ biggest story will be the strong winds ahead of an approaching cold front. We’ll see plenty of sunshine in patches throughout the day, as there’s not enough moisture along the front to totally scour the sun out. Many of us will be warmer today; it’s just that it will feel cooler due to the winds. We’re not nearly as cool this morning as this time yesterday, as the winds are already whipping around the region.
There’s a Wind Advisory in place through 6:00 p.m. for those in far eastern KELOLAND, including MN. Highs will push well above average as we take advantage of compressional warming. There will be some cooling before dark in western SD. Strong NW winds behind the front are to blame, and we could have a few snowflakes in the Black Hills before midnight. This system is moisture starved and anything that falls should be fairly light. The thin line will race across our area tomorrow morning and a quick hit of light rain is possible for most tomorrow. More light rain will return to the east late in the day. There is very little moisture to work with in the northern half of South Dakota.
The second and more impressive piece of the storm comes into the SW corner of the region by early Tuesday. There is more moisture and more cold air to work with, and that’s why the threat of more snow looms. The best moisture is along and south of I-90. I think we’ll have a couple of inches of snow in some spots in Iowa and SW Minnesota. As is often the case, Sioux Falls is the change-over area. We’ll start out as rain and eventually change over to a snowy/slushy mix. The models keep cooling the air off, but just above ground, we’ll be too warm early on. We do finally rebound and warm up by Thursday and into the new weekend.
