Northwest Iowa is watching for the potential of freezing fog and freezing drizzle tonight into the early morning hours while central Iowa is watching a line of thunderstorms moving through with one of them being severe warned!
Very foggy conditions have hung around much of the state today and should continue through the night, this has prompted the NWS to issue Dense Fog Advisories for portions of southeastern Iowa. Although no Dense Fog Advisory is issued for northwest Iowa, the same can most likely be expected there tonight. The exception is with near freezing temperatures in that region, a more likely chance will be there for Freezing Rain/Fog. Lyon, Sioux and Plymouth counties in northwest Iowa have been listed under a Freezing Rain Advisory. Surrounding areas should still keep an eye on conditions as they could also be treacherous for driving.
The severe weather is mainly affecting a small portion of the state, as only one cell has been severe warned. But, this cell has maintained its’ severe status for over 30 minutes. Counties of Madison and Dallas were listed under the warning at 9:23 PM with the potential for penny sized hail. Madison county was dropped from this warning as the cell moved into eastern Dallas county and has maintained its’ potential for severe weather. The storm is currently to the northwest of Des Moines and looks to be moving to the north/northeast at 30 mph. The warning expires within a couple of minutes and I do not believe it will be extended, but still a lightning show and some moderate rainfall when you don’t usually see that as we near the middle of December. Hence the title of ‘Surprise!’
