The Return of the Clipper

Well all good things must come to an end. Our highs today in the state ranged from the mid 30’s across northwest Iowa to the upper 50’s across southwest Iowa. A weak cold front is currently moving through the state this evening, which will be switching those southerly winds to the west. This will lower our high temperatures on Tuesday a few degrees cooler than where we were today. Highs on Tuesday will range from the mid 30’s to the mid 40’s across the state. Tonight the clouds will be on the decrease, however, they will begin to build back in Tuesday morning ahead of our next clipper system which will move through the northern portion of the state Tuesday afternoon.

This clipper system will be weak so we are not expecting a whole lot of precipitation with this system. As we stated, this clipper will mainly impact the northern half of the state. Some light freezing drizzle may be possible as early as tomorrow morning, but the bulk of the moisture will come Tuesday afternoon. By 3pm Tuesday, a rain/freezing rain mix will begin to into into northwest Iowa. At this point, temperatures still appear to be warm enough that any precipitation would be in the liquid form.

As you see from the graphic above, this system will be weak and will not produce a lot of snowfall. Another quick moving system will then be right behind this system on Wednesday. This second system will move through Wednesday mid morning into Wednesday evening.

Snowfall accumulations of 1″ to 1.5″ will be possible across northern Iowa, with the greatest accumulations along the Iowa/Minnesota border. Some very minor ice accumulations may be possible in northern Iowa early Tuesday morning so this is something that we will keep an eye on as any ice accumulations would could hazardous travel conditions.

This clipper system seems to be a little more organized than the clipper system that will be moving through tomorrow. As always, we will continue to keep an eye on all the very latest and will bring you those updates on our Facebook and Twitter pages, and right here at www.iowachase.com.
