18z HRRRX model
Note: Locally heavy rainfall is possible Sunday into Sunday evening in a swath from central and eastern Minnesota into central and northern Wisconsin with much lower rainfall totals expected farther north across northern Minnesota. Flash flooding could develop Sunday if thunderstorms develop and move over the same areas for a period of time, this threat looks most likely to occur in east central Minnesota into north central Wisconsin.
Note: Potential is there for an active severe weather day on Sunday especially over parts of central, southern and eastern Minnesota into western and north central portions of Wisconsin.
23z HRRR model run valid for 9 AM Sunday
Times below are approximate and could end up being a little earlier or later than what is shown on the map.
Another day featuring a dramatic temperature increase near Lake Superior, remember last Sunday temperatures started very warm but dropped like a rock later in the afternoon, while today was the opposite, started kinda cool but warmed up quickly early this afternoon as east winds gave way to very strong southwesterly winds. Note: The temperature at the Duluth Harbor went from 61 degrees at 12:14 PM today to 86 degrees at 12:34 PM as the wind shifted directions from east to southwest.
The high temperature of 88 degrees at the Duluth Airport today (June 10th) was good for 2nd warmest high temperature on record for today's date. The record high temperature is 92 degrees which was set in 1956.

For Duluth and Superior
-Stays dry and mild tonight under partly cloudy skies. Lows in the 50s to around 60 degrees.
-Winds will shift around to the east for Sunday so it will not be as warm as it was today (Saturday) highs should be in the 70s but it will be cooler near Lake Superior. There is a chance for some showers and possibly a few thunderstorms at times beginning after 9 AM and continuing into the early evening hours but there is also a chance that we remain dry as the rain sets up a little farther to our south. Tricky forecast for Sunday could go either way!
