A warm and humid air mass will remain in place across the Northland the next few days with highs mainly in the 80s with lows in the 50s to around 60. Temperatures will continue to be cooler, however, near Lake Superior on a daily basis through this weekend due to a persistent easterly wind, this will keep temperatures in the 50s to around 60 during the day and in the 40s at night within about 10-20 miles of Lake Superior.
It will also remain somewhat humid with dew point temperatures in the 50s and even some 60s at times over the next few days.
Chances for showers and thunderstorms will continue across the Northland on a daily basis through this weekend but note just how scattered this rain has been today per radar rainfall estimates (ending just before 5 PM Tuesday). A similar setup will likely occur the next few days so although rain chances remain in the forecast, this rain will continue to be scattered in coverage meaning not everyone will get rain, but if you do get a thunderstorm, then you likely will get a period of heavy rainfall.
Blue colors on the map below represent one-hour rainfall rates of 0.50″+, with the purple colors representing one-hour rainfall rates of 1.50″+.
