In regards to next weeks storm system, it comes as no surprise that the models continue to flip back and forth. The system is still out in the Pacific Ocean, which impacts how the models are able to get a handle of it. There is a lot of data that goes into weather models. One of the pieces that go into these weather models, are surface observations, measured by surface stations across the country. When a system is over water, this is just one less piece of the puzzle that is included in the box, making it an incomplete puzzle. Once the system makes landfall, it starts to become a little more clear what will happen.
The models have been all over the place the last 48 hours. One model run will be east, and in the next run, the model will be really far west. So at this point, we must be patient and wait until the models begin to lock-in on a solution. This is why you do not share snowfall maps a week out, especially ones that are clearly obvious that will not come to fruition. The record Iowa snowfall for a single storm is 24″. So to share a map that shows more than that, is just unreasonable.
What does appear to be locked-in, is the below average temperatures expected next week. The Climate Prediction Center has placed most of the country under a probability of being below average.
We will continue to keep an eye on the system next week, and will let you know everything you need to know about it when the time is right. Until then, sit back and relax! We have you covered.
