Rain is expected to change over to snow on Thursday morning, creating a sloppy and slippery start to Halloween for many in Minnesota including in the Twin Cities which is under a Winter Weather Advisory from 10 a.m. until 4 p.m.
Snow is expected to develop starting in the morning making the early morning commute a tricky one, with northwest winds gusting up to 30 miles per hour throughout the day.
"There will be a very narrow band within the area where the rain changes over to snow where we could see some pretty heavy snowfall rates," said National Weather Service Meteorologist Eric Ahasic. "If you were to measure it every hour, you may see an inch or more per hour."
Due to warm surface temperatures, there's high uncertainty when it comes to accumulation according to the National Weather Service in the Twin Cities.
"It's going to be kind of tricky to measure," Ahasic said. "If you measure it on your dress, or on the hood of your car, your grill on your porch, or on the sidewalk or road you'll probably get a couple of different numbers. In some areas of the state we will see at least a couple inches of slushy accumulation."
It appears the heaviest snowfall will stay north of the Twin Cities and come to an end in the afternoon, ahead of trick-or-treat time.
"That's the good news," added Ahasic. "Temperatures are going to be pretty warm. Basically as that snow is falling they'll cool just enough to keep temperatures hovering above 32 or 33 degrees. As it ends, those temperatures should warm-up a bit and we shouldn't have any lingering snow or rain at trick-or-treat time."
Temps are expected to climb to the upper 40s on Friday and into the mid 50s Saturday and Sunday.
