Snow and rain is back in the forecast tonight. This morning, snowfall totals of 1″ to 3″ looked to be possible with the greatest accumulations across northeast Iowa, however, this afternoon the warmer temperatures are going to throw a curve ball to this forecast.
A clipper system will continue to drop to the southeast this evening, and as it does, rain will begin to build into to the state from the northwest. Temperatures overnight look to remain above freezing, so this will impact the transition over to snow.
By 6am Sunday, temperatures look to cool off enough, that rain will begin to transition over to snow, mainly across northeast Iowa. This is also where we will be expecting the greatest snowfall accumulations. Due to this later transition from rain to snow, snowfall totals of 1″ to 2″ now appear to be possible. However, if we see an earlier transition over from rain to snow, then snowfall totals could be higher. Central and southwest Iowa, will remain warm enough during the majority of this system that most of the precipitation will fall as rain. However, a little bit of snow will be possible, but not expecting much if any in the way of accumulations.
The remainder of the week will remain above average, but by next weekend we are looking at a return of the winter temperatures. Highs by next weekend will be in the teens to 20’s, with even colder temperatures possible going into the first week of February.
