The special weather statement in the Twin Cities Wednesday morning warned of falling temperatures causing black ice and slippery road conditions. "Please drive slowly," the national weather service's statement read.

The temperature at 8:30 a.m. was 12 degrees and felt like -4 with 14 mph winds. The daily forecast calls for a high of 21 and a low of 10 degrees with mostly sunny skies.

A year from now, this forecast might spook football fans visiting the Twin Cities and U.S. Bank Stadium for Super Bowl LII. This week in Houston, host of Super Bowl LI, the average temperature is in the 70s with Sunday's game day forecast calling for 77 degrees and cloudy skies.

Afternoon sun is expected in Minneapolis Sunday, though the high will be 29 and low 14 with 10 mph winds.

The temperature swing in the Twin Cities this week does offer hope that next year's Super Bowl week will produce mild temperatures for the Upper Midwest. This week kicked off with limited snow flurries, but any new snow was gone Monday when the high was nearly 40 degrees and low 29.

Tuesday produced another day above 30, but by Wednesday morning and the first day of February, the temperatures began to plummet.

Skyways and indoor events will allow visitors and Minnesotans to enjoy the week-long event in 2018, but if temperatures stay above 30 and flirt with 40, then the party will extend outdoors.

The average high temperature in Minneapolis over the past five years on Feb. 4, next year's game day, is 21 degrees and the average low 6 degrees. The high during this span was 36 degrees in 2012. The low was -1 in 2014 and 2015. The average precipitation is .03 inches.

In 2005, a record high of 51 degrees was set. The record low of -28 was set in 1996.

Football fans in Houston Wednesday can expect a high of 78 degrees and low of 68 with a chance of rain.
