A quick post on our snow totals and upcoming cold temperatures and dangerous wind chills.
Look for below 0 temperatures for 30 or more hours starting around midnight tonight. Lows may be lower than 10 below zero tonight and tomorrow night. Windchill values will be in the minus 25 to minus 35 range through Tuesday midday.

So it look as though Winter may rear it’s head later this week for the St. Louis region. A cold front is expected mid-week that may bring the coldest air of the season into the area. The question becomes where the moisture will be?
Several models are painting several inches of snow over our region through the end of the week, recent outputs have shifted the heaviest precipitation just south of our area, but still leave us on the northern edge, I am sure this will change one direction or the other. Late next weekend into the beginning of the following week we may see another chance for Winter weather.
Along with our automated forecast on our website, we also provide precipitation maps that look out 3 days, they include rain and snow forecast from 3 different models using our own software and the official snow and ice maps from the St. Louis National Weather Service.

As many know I get out and chase storms as time allows. The past couple of days I left the St. Louis, MO area and chased storms in Kansas on Sunday then Oklahoma on Monday. This trip I was by myself and met up with other chasers to help in in navigation during storms.
On 5/20 I left Iola, KS around 8 am headed towards the Tulsa, OK area to evaluate chase plans. To my surprise there was a severe warned storm just 15 minutes from my location. I did what a chaser does, fired up the video stream on ChaserTV and found a good area to view that storm. After 45 minutes or so it was time to move on, messages were coming in from a friend, Dave Toner, who was chasing that day also, I had decided to follow him along with Brian Hurst and Jason Blum, Targeting the Oklahoma City area. As I continued the plan was made to go about 30-40 miles south of the city for storm development, we met up shortly before 2 pm as 3 supercells were already exploding in the area. We were closest to the middle of the 3 storms as we sat just south of Lindsay, OK. We had thoughts of leaving it several times, but this storm kept drawing us back, one minute looking like it was done only to come out from behind trees with a ground scraping wall cloud. Reports starting coming in from the Moore area of complete destruction, even when we stopped for a closer look at our storm I didn’t look for any images, the descriptions people were giving were enough. After about 3 hours of chasing our storm, we were finished, we went our separate ways and I decided to call the chase trip off and start heading back towards home in MO. I stopped for gas and started taking in some of the media online of the Moore area along with numbers of injuries and deaths. This was one of the longest drives home I have ever experienced, I was 8 hours away from home and just wanted to be with my family. There was nothing that could be done to get home any faster and I would just be in the way in Moore. Everything was done right, the tornado warnings were issued 16+ minutes ahead of time, it was up to the people to take the proper precautions. Most obviously did, although the numbers have been reduced 20+ lives lost is still to many.
Please be weather aware people, if you are not in a sturdy building and a warning is issued, get out, make plans ahead of time where you will go. Have alternate plans in case you are not able to access planned shelter, at just 30 mph you can drive 8 miles in warning time given. Please don’t stay in your car or park under overpasses, these are not safe places to be and you will block traffic for those trying to get away from the storm…..
We continued our struggle with the transition into spring this week and at this time appears that the upcoming week will be more of the same, possibly even a shot of winter somewhere in the Midwest…
Our high temperature for the past week was 72° and our low was 35°, we picked up 1.57 inches of rain.
The outlook for the upcoming week brings very warm temperatures in early on, mid 80’s are not out of the question through mid-week. Rain chances pick up after Wednesday, there is some indication that this could bring heavy rain in or near our area. This is a concern as the big rivers have recently crested, heavy rain would likely bring another rise in the already swollen rivers. The temperatures late week will cool back down, the computer models have not come into an agreement on this, so it’s hard to pin down. I wouldn’t be surprised to see some mornings in the low 30’s come late week. I hope I am wrong and we only see 40’s.
Along with the temperature uncertainty, there are indications of a May snowstorm somewhere in the Midwest this week. It will be interesting to watch, I have been laughing all day that somewhere this week someone may have to cut grass and shovel their driveway…. Have a great week everyone!
