Storm System to Impact Iowa Thursday

The start of the work week will be mild and dry, but major changes come by Thursday. To start out the week, temperatures will be in the 40’s and 50’s, so if you have any remaining outdoor tasks to do, get them done before Thursday.

On Thursday, a trough will push an area of low pressure out of the desert southwest, and this area of low pressure will begin to increase our precipitation chances. It appears that initially precipitation will fall in the form as rain, but will then transition over to snow as cold air gets pulled into the state from the northwest. Precipitation should begin sometime after noon, and the transition over to snow currently appears to occur sometime late Thursday afternoon.

The models differ on track past Thursday night, which is why there still remains a bit of uncertainty regarding this system. Since we are still a few days away, no snowfall totals will be forecast at this current time. We decided to talk about this system sooner than we typically would since many of you will be hitting the roads either Thursday or Friday to make it to your destination in time for Christmas. Looking past this system, the models bring yet another system through the state by Christmas morning, so it is looking very likely for a white Christmas at this point.

Make sure to check back to our Facebook and Twitter pages for the latest updates regarding this storm system if you do plan on traveling.
