Tue 6/23 -12pm Update: Isolated to scattered severe storms are forecast this afternoon, including the potential for large hail and tornadoes. There have been a few updates from this morning's severe potential forecast. Thunderstorms are now expected to develop a bit earlier than previously forecast - now early afternoon. The potential for larger hail (now up to golf ball sized) has increased, along with a small increase in the chance for tornadoes, particularly within portions of northwest to west-central Minnesota. While not widespread, couldn't rule out isolated instances of gusty winds to 60 mph.
An upper low will move slowly east thru southern Canada today into Wednesday. As it does a cold front will move east into the area mid to late afternoon. This will bring periods of showers and thunderstorms, most numerous in northeast ND and northwest MN. Rainfall amounts are forecast to be in the 0.20 inch to 0.80 inch range, but locally over an inch rain amounts possible in the next 48 hours.
