You may not have realized just how close fall is until you walked outside Tuesday morning. Temperatures plummeted to the 20’s in a few areas with many falling to the low to mid 30’s. By South Dakota standards, this is nowhere close to what we would call cold. But with as warm of a spring and summer as we have had, it is certainly a shock to the system, especially if you are unprepared. There has been a lot of talk around the water cooler Tuesday with many thinking that this is early for our first reasonable frost. Well I can put that to rest right now and tell you that its not. In fact, many locations should have had their first freeze in the next couple of weeks so Id say we are pretty much on target. The temperatures sure have been extreme over the last week or two with records highs last week and now freezing conditions this week, but it looks like the cool and dry pattern could hang around. A large trough is now digging into parts of the eastern U.S. that will lead to very fall like conditions in many locations east of the Rocky Mountains. This trough will just sit in many of the same areas through the weekend with some signs that it could sit through next week as well. For the details, check out all of the information below.
Many areas north of I-90 experienced their first frost Tuesday morning but some spots got their first freeze as well. Check out some of the coldest numbers found across the area Tuesday.
It has been a whirlwind of temperatures over the last week with large contrasts from day to day and from east to west. These are common this time of the year as we transition into the cooler months, but it just seems to be a little more drastic this year then in years past. Check out the high and low temperatures over the last week for Sioux Falls.
Impressive to see temperatures swing so wildly going from the 90’s to the 30’s in just a few short days. But it does look like the cooler temperatures will stay in the forecast for a few days thanks to a large trough hanging out in the eastern half of North America. The following is a look at the jet stream forecast for Wednesday morning and Saturday morning.
Notice that the trough in the east seems to just park itself over the east and even dig a little deeper as we head into the weekend. This spells plenty of cool temperatures for our area and points eastward. The one thing this type of pattern doesn’t do is bring rainfall, which many areas still desperately need. So expect sunshine and coolish weather right through your weekend.
