Marginal risk for severe thunderstorms for Thursday night (Dark green shaded area on map)
Water vapor satellite loop from September 20, 2017 — Active weather pattern in place. Tropical Storm Jose still spinning off the east coast while numerous low pressure systems are affecting the northwest U.S.; western and central Canada.
Southwest flow aloft remains in place today behind the strong storm system which affected the Northland early this morning. Late this afternoon, high pressure was over central Nebraska with a few areas of low pressure to our northwest. Scattered showers and mostly cloudy skies continued this morning but dry air helped to erode the clouds this afternoon with sunny to mostly sunny skies in most of the Northland. Highs today ranged from the mid 60s to low 70s with a few locations near Lake Superior between 73-75 degrees at 5 PM today. Southwest winds were a tad gusty this afternoon with wind speeds in the 10-25 mph range.
*Quiet weather tonight so for those who don’t like getting woke up by a thunderstorm at 3 AM will enjoy the quiet/peaceful weather will have tonight. Mostly clear skies are forecast with lows in the 40s to lower 50s…Maybe a few 30s in the traditional cold spots.
*Should stay dry during the day Thursday under partly to mostly sunny skies with highs ranging from the lower 60s near Lake Superior to the upper 60s to middle 70s farther inland. Cold front which moved through earlier today will turn into a warm front while it lifts north into Minnesota and Wisconsin Thursday night — Will be dealing with a strengthening low level jet once again Thursday night which will transport deep moisture and elevated instability into our area. Scattered showers and thunderstorms could develop in parts of northeast Minnesota and northwest Wisconsin Thursday night with a few strong to severe thunderstorms possible. Hail, heavy rain and lightning would be the main threats from those storms.
