Nowcast: Next rain wave moving north; steadier, heavier rain through evening

Soaking rain tonight, some snow up north

Our wet start Tuesday gave way to several dry hours surrounding midday. But the storm system is moving closer to Minnesota, and the next rain wave is moving north.

NOAA’s NAM 3 km resolution model shows the next rain wave spinning north through the evening.

Snow up north

This system will draw in just enough sub-freezing air to change rain to snow in parts of central and northern Minnesota Tuesday night into Wednesday. NOAA’s NAM 3 km resolution model picks up on that trend.

An inch or two of slush may accumulate from Alexandria into Brainerd. But some locations from near Grand Rapids through the Iron Range to near Ely and the BWCA could see 2 to 5 inches of wet snow by later Wednesday.
