Enjoy these warm and unseasonal temperatures while they last, because there is a big change in the extended forecast. Today our highs will warm up into the mid to upper 50s and will be in the mid to lower 50s tomorrow.
Our next storm system will move through the state Thursday into Friday, bringing with it the chance of rain and snow. Precipitation will start off as rain during the day on Thursday and will transition over to snow Thursday night. Snowfall accumulations look to remain light with the heavier snowfall accumulations to the north. Now if the changeover to snow occurs sooner, then we could be looking at greater snowfall totals. Across southern Iowa, a light dusting is possible and northern Iowa could see 1”-3”. As stated earlier, if the changeover from rain to snow occurs sooner, then these totals will need adjusted.
Behind this system, temperatures will be dropping off to winter like temperatures. The image above is of lows Friday night. Lows will range from the single digits to the teens. Also note in the picture, the black lines stretching from north to south. These lines are called isobars, or lines of equal pressure. If you notice, there a many of them in the state. This signifies that there will be breezy winds and this will not help with the already cold conditions. If you combine the wind and the already frigid temperatures, it will feel like the single digits to below zero temps. If there is also snow accumulation, these temperatures may be lowered due to the snow so it will be getting very cold in the coming days.Enjoy the warmth while it lasts, and as always we will continue to keep an eye on this system and will bring you the very latest on our Facebook page and right here at Iowachase.com.
