Flood Watch in effect through Tuesday morning for parts of north-central and northeast Minnesota including the cities of Pine River, International Falls, Ely, Brainerd, Hill City, Grand Rapids, Walker, and Bigfork. Flash flooding caused by excessive rainfall possible. Several rounds of thunderstorms are expected through late Monday night. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying flood prone locations. Since water bodies are already running high, relatively low rainfall amounts may cause flooding.
On average we’re looking at a potential for 0.50″ to 2.00″ of rain in much of the Northland through Monday night with locally higher rainfall amounts for areas that see multiple rounds of thunderstorms.
SEVERE WEATHER POTENTIAL THROUGH TONIGHT
Isolated to scattered strong to severe thunderstorms are possible late this afternoon into tonight in much of northeast Minnesota and northwest Wisconsin with the highest threat covering areas from around Brainerd on south.
Primary severe weather threats through tonight include damaging wind gusts to 60 mph and large hail of quarter size to ping pong ball size (1.00″-1.50″ diameter).
Enhanced Risk (level 3/5) orange
Slight Risk (level 2/5) yellow
Marginal Risk (level 1/5) dark green
Simulated radar forecast through 12 PM Monday showing the multiple rounds of showers and thunderstorms which are expected to affect much of northeast Minnesota and northwest Wisconsin through the end of this loop which is Noon on Monday.
A warm frontal or nearly stationary frontal boundary extending from central North Dakota to central Minnesota to central Wisconsin late this morning will be one source of lift for shower and thunderstorm development through Monday morning. This boundary won’t be moving a whole lot north or south over the next 24 hours.
