The Channel 13 Weather Team is closely watching long-range model data. The latest models show this storm system crossing Iowa a day later, Tuesday through Wednesday now.
It is important to note that seven days out, the track of far off storms systems can shift in position and intensity before the time frame of concern. So check back with whotv.com for updated information.
Groundhog Day Snow
Wednesday morning models indicate a closed low-pressure system lifting into Iowa from the southern plains, a day later, on Tuesday of next week. This means the timing should avoid impacting Caucus Night. This could first bring a mix of rain, freezing rain, sleet and snow before transitioning to all snowfall through Wednesday.
We don’t know the exact temperature profile during that time frame quite yet, so snowfall totals could be light with a warmer air mass in place with just a couple of inches of snow through Tuesday morning. If colder air dives in sooner or the track of the storm shifts further south, snowfall totals could be higher. The heaviest band of snow fall has shifted farther south with the latest track of the storm and would take the heaviest snow across Central Iowa.
Winds will also be very strong, so blowing and drifting of snow could be a problem.
What does look to be sure for next week is that temperatures will again be significantly colder with highs in the teens and 20s after our mild weekend in the 40s.
