Winter Storm Watch Issued: Heavy snow potential late Wednesday through Thursday
A rain/snow mix is expected Late Wednesday before transitioning to all snow by early Thursday morning, with moderate to heavy accumulations possible.
- Taking care of business for today, temperatures will peak nicely in the 50s and 60s, with a few afternoon thundershowers possible.
- Areas of locally dense fog will be possible this morning in the Eastern Foothills and towards the South Dakota plains, give yourself extra time this morning.
- We do have some fog roaming around the South Dakota Plains this morning, some areas have less than 1/4 of a mile of visibility… stay alert!
- A Winter Storm Watch has been issued by the National Weather Service in Rapid City for the potential of moderate to heavy snowfall in the higher elevations of the Black Hills.
- It is my belief that more of these watches and advisories will be issued for areas outside of the Black Hills over the next 24 hours, be sure to stay tuned.
- The irony of the winter storm watch and our afternoon high temperatures is not lost on us… could push 70° in many areas today
- Much like Monday, a few afternoon thundershowers will be possible this afternoon given our warm temperatures and approaching system.
- By this evening, things will be on the breezy side with isolated showers pushing through the area, temperatures will be on the cooler side by Wednesday morning in the 30s and 40s
- The first part of Wednesday is expected to be relatively dry, with moisture and energy pushing in from the South and Southwest by the afternoon, this could lead to a few rain showers.
- By Wednesday evening, we’re kicking things up a notch with heavier bands of precipitation beginning to cover the Southern portion of our area.
- This will eventually fill in to most of the region by late Wednesday night.
- Some areas may start out as rain, with most transitioning to snow by the midnight hour.
- Our warm, sunny days will help keep roads relatively clear for the first part of this system… with light surfaces collecting several inches of snow before anything noticeable is recorded on paved roads.
- By midnight going into early Thursday morning, we’re expecting full snow-mode across the area, with heavier bands sticking to the I-90 corridor and the higher elevations of the Black Hills.
- All the way through 11 AM Thursday, snow will continue across the region with temperatures hovering in the upper 20s and low 30s.
- This could lead to so large, wet snowflakes and quick accumulations. Roads by this point will be pretty well covered in portions of our area.
- We start to see the tail end by Thursday evening, with cold, but dry air filtering in from the Northwest.
- By late Thursday, most activity will have pushed East save for a few stubborn snow bands.
- Temperatures could easily hit the single digits across large portions of the area with a stiff Northerly breeze.
- Accumulation maps are still coming together, but something to note is there has been very little shift in our expected region of heaviest snowfall.
- Things could still shift South or North, but not enough for this system to miss us. We are looking at a good potential for moderate to heavy snowfall for a large portions of our area.
- Stay tuned over the next 24 hours, as we’ll really start to get a good idea of exact timeline and specific impacts. The good news is we’re pushing into April, and warm road surfaces will keep things on the slushy side… at first. These roads will eventually freeze, as we are looking at temperatures in the teens and in some cases the single digits. Stay weather aware, and stay tuned for more updates. Thanks for trusting us with the forecast, and stay safe out there. Wash your hands! -Brant
