Storm Center Update - Saturday PM

Tonight, our eye is on a snow-maker tracking mainly north of the border. The big factor for us is high southeast winds. That will keep us from cooling down much tonight (except in Rapid City, where it got to 56 today!).

We've got a High Wind Warning and Winter Weather Advisory across much of KELOLAND. The highest winds will be west of the Missouri, gusting up to 50 mph tomorrow. The best chances of snow are in the northwestern Black Hills and the NW faces as well as the closest counties to North Dakota. Accumulations should not be too heavy, but that's little respite when it's so windy. Visibility will be down wherever it snow. Flurries have an outside shot of reaching down to I-90.

Tomorrow's winds will continue. Despite those winds being from the SE, we just can't warm up a whole lot. By and large, we'll only be in the 30s. Monday is the change-over day. Winds should be fairly light and there will be some sunshine, but it's going to be below-average-cool.

Starting Monday night, the tightly packed system is coming our way out of the Four Corners. This track and intensity has stayed remarkably consistent over the past couple of days. Sioux Falls is in the warm sector for much of this, and that could signal freezing rain mixed in with snow. The core looks to be in the NE quarter of South Dakota. This is where heavy snow could easily be dumped. Things change quickly, especially this far out (at least 48 hours) but it's still got the potential to be the winter's best storm. We think this will last through early in the day Wednesday, so it's a lengthy span.

After that, we're monitoring a slight chance on Thursday but our focus remains affixed to the first two rounds.
