Thanksgiving Travel 11/22

Many you will be traveling this week, and are wondering how the weather will hold up. The good news is if you plan on traveling early in the week, the weather will be great! Temperatures will be on a warming trend through Thursday, with highs in the 40’s and even 50’s. However, by Wednesday evening, the weather will begin to potentially impact your travel.

Forecast surface map Wednesday, an area of low pressure will be developing near the Rockies, which will begin to advect moisture northeastward. Temperatures Wednesday night will be above freezing which will keep all precipitation in the form of rain. Temperatures on Thursday will remain above freezing for the beginning of the day, but a cold front will move through the state, which is when problems could arise.

Iowa Rainfall ForecastMost of the state will see a good amount of rain from Wednesday night into Thursday evening. The heaviest of the rain will fall across the southeastern half of the state. This is where rainfall totals of 1.8″ will be possible.

Iowa Thanksgiving Snowfall Forecast As we mentioned earlier, as the cold front begins to move into the state Thursday afternoon, rain will begin to transition over to snow. The good news is that when this transition begins to occur, most of the precipitation will be east of the cooler air, which means not a whole lot of snow will be expected. Some light snowfall accumulations may be possible across northwest Iowa, but this looks to remain very light.

Iowa Freezing Rain ForecastThe models also try to develop some areas of light freezing rain during this transition from rain to snow. Any freezing rain will be very light, but this will be highly contingent on the arrival of the cooler air. Any change in track and timing is subject to change this forecast, so it will be something to we will monitor this week, since it will be a highly traveled week.
