Meteorologists are keeping a close eye on a winter storm headed toward the region Tuesday that could leave 6 inches of snow, rain or a mix of the two behind.
"This is really more of a March storm," said Gino Izzi, meteorologist with the National Weather Service in Romeoville, Ill. "The small difference between 34 (degrees) and 32 will make a big difference."
Cook, Will and LaPorte counties are under a winter storm watch all day Tuesday, but Izzi said he anticipates a winter weather advisory will be issued for those counties and all others in Northwest Indiana by day's end Monday.
Snow, possibly mixed with sleet, is expected to begin late Tuesday morning and before tapering off early Tuesday night. Winds gusting to 40 mph, especially near the Lake Michigan shore, are possible.
Izzi said the worst conditions will take place between late morning and late afternoon. If the precipitation is primarily snow, travel could be hazardous.
