There is a lot that will be going on in the weeks ahead in the weather department. To start off, things will be warming up this weekend. Temperatures will be warming up into the 50’s possibly a few 60’s across southern Iowa if we get enough clearing before a low pressure system moves in on Sunday night into Tuesday bringing a chance of rain and snow. Most of the precipitation will fall as rain initially, but colder air will be moving in during the afternoon hours on Monday and this will transition rain over to snow across northwest Iowa. Monday evening, some light snow showers will be possible further to the southeast.
Accumulations will be on the light side across northwest Iowa. Accumulations of 2″ to 3″ inches will be likely. The models have been fairly consistent with this system, however, there is still time for this system to shift a bit. This will need to be watched as any shift in the track will change snowfall totals.
After this system clears out, high pressure will begin to build into the state, with seasonable temperature setting back in. In the extended forecast, there is a system the will need to be watched around the 20th. This morning we told you about what the models were trying to do. However, we also said that it was not a forecast since we are still over a week away. Any snowfall forecast that are more than three days away, have a very low percentage of verifying. The afternoon model runs came in, and sure enough, things flip flopped and changed once again, as expected. Many of you are planning on traveling around this time, so we still want you to know, that you will need to continue to watch for the latest updates on this. Right now there are a few signs that may weaken this storm, and make it less impressive than what the models are currently trying to show. We will leave it at that right now, but take any snowfall forecast that far out with a grain of salt. Until then, continue to check on the very latest updates throughout the week.
