Detroit Lakes, Minnesota - (6:30 p.m.) The Minnesota Department of Transportation and the Minnesota State Patrol will close Interstate 94 from Moorhead to Alexandria and Highway 10 from Moorhead to Detroit Lakes at 7 p.m. due to hazardous road conditions. The highways will remain closed until further notice.
Snow plows will be pulled from all area state highways and interstates in Mahnomen, Clay, Becker, Wilkin, Otter Tail, Traverse, Grant, Douglas, Big Stone, Stevens, Pope and Swift counties. Motorists are advised not to travel until conditions improve and Mn/DOT and the Minnesota State Patrol open the roads.
Motorists should plan accordingly. When a road is closed it is illegal to travel in that area. Motorists can be fined up to $1,000 and/or sentenced to 90 days in jail. In addition, if travelers need to be rescued from a closed road, other expenses and penalties will apply.
Sightings were reported in Scottsdale, Paradise Valley, Fountain Hills, Cave Creek, Carefree, Peoria, Glendale and Anthem, Apache Junction, Mesa and parts of Phoenix.

Phoenix - Blizzard conditions were moving across the West on Thursday after shutting down major roads in Arizona, blasting California and Nevada with frigid winds and leaving an area of western Washington in a white-out on Wednesday.
Heavy snow fell in some mountainous regions on Wednesday and rains soaked lower elevations, cutting power to thousands and causing numerous traffic tie-ups and accidents.
A blizzard warning was issued in parts of Arizona on Wednesday, and forecasters warned the system would move into neighboring New Mexico on Thursday. Colorado's mountains could see up to two feet of snow by Friday.
Below is an overview by state.

Safari West staff members Brian Jellison, left, and Cervando Cornejo work on removing a fallen oak tree on Wednesday. The tree crushed a wood-frame canvas tent and killed a visitor at the wildlife park, east of Santa Rosa, on Tuesday evening.
One person was killed by a falling tree and a snowboarder was missing, power outages were scattered around the state and some roads and highways were closed, but the region escaped widespread problems in the two-day round of foul weather.
Chilly wind gusts of more than 40 mph hit northern Los Angeles County as the low pressure system that brought the storm moved east, and forecasters warned that the night would allow even colder air and higher winds that could down power lines and topple trees rooted in saturated soil.
An expected drop of snow levels to low elevations also posed a threat to highway travel over mountain passes.
Meanwhile, communities east and south of Los Angeles that were hit hard by runoff in a dayslong series of storms last week were able to focus on cleaning up without additional new damage.
Berlin and the surrounding state of Brandenburg have never seen such a thick snow in December for more than a century, as some places received 40 centimeters of snow since Dec. 1, the weather agency said.
The rain will continue to spread from northwest to southeast across Southern California this morning, falling heavily at times.
Several roofs have collapsed under the snow.
Moscow has been hit with freezing rain which has made roads and pavements dangerously slippery.
It has also caused traffic chaos, with 2000 kilometres of traffic jams reported around the capital as people try to go shopping for next weekend's Orthodox Christmas.
"You can't even imagine how bad this is. The roads are closed, and they are digging and digging, and they just can't get through," said Helle Skov Olesen, who lives on the island nestled between Sweden and the northern coasts of Germany and Poland.
"They don't even know where to put the snow," she told daily Politiken.
Denmark's meteorological institute (DMI) measured 140 centimetres (55 inches) of snow on Bornholm, "the equivalent of the amount of snow at various ski resorts," Steen Rasmussen of the institute said.
Up north, Winter Storm Watches are now in effect from 7 a.m. Wednesday through 12 noon Thursday above 5000 feet. Right now, we are expecting anywhere from 8-16" of snow above 6000 feet and about 4-10" from 5000 to 6000 feet. That cold front will be bringing some very strong winds (gusts near 40 mph) to Northern Arizona too. So, blowing/drifting snow will make travel in the high country very difficult Wednesday and Thursday. As our skies clear out late Thursday, temperatures will plummet!
The powerful low-pressure system brought blizzard conditions from northern New Jersey to Maine over Christmas weekend. The GOES-13 satellite captured an image of the storm's center off the Massachusetts coast and also shows the snowfall left behind.
As of 1:30 p.m. EST, all blizzard warnings were canceled as the low has pulled much of its snow and rain away from land areas and into the North Atlantic Ocean, according to NASA. Winds behind the system are now causing more problems for residents along the U.S. East coast. Gusts were recorded as high as 80 mph.
