It has been a foggy day with visibility near zero at times. The fog has improved a little this afternoon in areas south of Highway 20. The fog will remain thick north of Highway 20 until about midnight. A DENSE FOG ADVISORY remains in effect until midnight.

Here is a look at the fog in Dubuque around 2:30 PM today.

The cold front that will bring in cold air and clear out the fog is located west of Iowa this afternoon…see map below.

Saturday will be wind and colder with temperatures in the 20s throughout the day. We are tracking another area of low pressure that could bring us some light snow part of the region. The low will track northeast putting southeast Iowa in the path for some light snow. Saturday night and Sunday morning light snow is possible southeast of a line from Cedar Rapids to Dubuque. Snow forecast is a trace to 2”. Northwest of that line will be mostly cloudy. Here is my snow forecast.

The map below is the snow forecast from the WSI RPM model.

The HPC also has a pretty decent chance of light snow in the same area mentioned above.

Next week will be quiet with highs in the upper 20s to low 30s.

January 11

From NWS
: Very strong winds spread across Iowa making it the windiest day in many years with a statewide daily average wind speed of 27.5 mph and gusts in excess of 60 mph recorded. The winds caused widespread soil erosion over the northwestern half of Iowa where there was no snow cover on the ground.

1975: An intense low pressure system moved northward across Iowa on January 10-11, producing a severe blizzard across western and northwestern portions of the state which was one of the worst winter storms on record and is often referred to as “The Blizzard of the Century” in that area. Storm total snowfalls were in the 8 to 15 inch range west of a line from Clear Lake to Denison to Clarinda with the highest reported amounts including 12.0 inches at Emmetsburg and Logan, 13.0 inches at Algona, 13.5 inches at Britt, 14.3 inches at Onawa, 15.0 inches at Sac City and Storm Lake, and 16.0 inches at Estherville. The heavy snow was accompanied by winds gusting as high as 80 mph which blew it into drifts as deep as 20 feet and paralyzed the region, stranding thousands of motorists and causing 15 deaths in northwestern Iowa. The storm also killed more than 100,000 cattle, hogs, sheep, and chickens.

 This Day in National/World Weather History …
 11 January 1898 → A tornado outbreak swept through the Ozarks. The worst tornado was an F4 that ripped through the heart of Fort Smith, AR at 11:15pm. Fifty-two people were killed in town, including 16 in one residential block. A Fort Smith street sign was found 22 miles away.
 11 January 1972 → Winds raced down the eastern slopes of the Rockies, resulting in wind gusts of more than 140 mph in parts of Colorado. Damage was estimated at $25 million.
 11 January 1980 → A chinook at Great Falls, MT took the temperature from 28 degrees below zero to 15 degrees above zero in seven minutes.
 11 January 1982 → Eight hundred fans were stranded at the Buffalo Municipal Auditorium following a Sunday evening hockey game after two feet of snow fell on the city.
