Many of you have been asking us what the travel conditions will be like over the Christmas weekend, since many have seen the chance for precipitation on Sunday. While this forecast is still very early, we wanted to update on the latest, mainly since a lot of you will be traveling. Due note, that this forecast WILL change, so we will be very vague on details.
The latest models have the track of the low tracking across northwest Iowa up into central Minnesota. This would keep all of Iowa in the warm sector, which would allow temperatures to soar into the 40’s and 50’s. With the current track, precipitation would be in the form of rain with dynamics possibly supporting the potential for thunderstorms.
As the low continues to track to the east, colder air will begin to wrap around, which may bring a little light snow by Sunday night into Monday. It appears that by the time the cold gets here, most of the precipitation will be gone, which is why little snow is currently forecasted. High pressure will begin to push in by Sunday evening which will increase pressure gradient. This will cause the winds to be very strong into Monday.
With the current track of the low, the best chance for snow, and potentially blizzard like conditions would be across South Dakota, North Dakota and northern Minnesota. Due to this storm system still more than a thousand miles off the west coast, the track of the low will change in the coming days. It is now wait and see how the models handle things over the next few days. Once the system makes landfall on the west coast, that is when models will begin to get a better handle on the track.
