Pleasant weather across the Northland this week

Looks like the final week of July will be a dry one across most of the Northland, but there could be a few isolated showers that pop-up during the afternoon and evening on Monday and Tuesday, but these shouldn’t amount to much where they occur, and the majority of these should remain north of Duluth and Superior.

Note: 5.25″ of rain has fallen so far this month in Duluth, and July 2020 will finish above normal in the rainfall department even if we don’t get anymore rain this month, but our precip deficit since January 1st will be climbing this week, or unless we get some rain, by the way we’re still nearly -5.00″ below normal for precipitation in Duluth since January 1st.

A mid to upper level low will move slowly ESE out of Ontario province from Monday to Wednesday, this will put the Northland in a NW flow aloft which will lead to a much more comfortable air mass across the Northland over the next few days. High temperatures on Monday and Tuesday are forecast to be in the 70s to around 80 degrees, right about normal for late July. It’ll be a touch breezy at times on Monday as northwest winds gust to around 20-25 mph.

A less humid air mass is on the move! It is taking a little while to get here, but a much less humid air mass will arrive in Duluth and Superior by this evening, and it looks like most of the week ahead will be quite comfortable in terms of the dew point which should mostly be in the 50s over the next few days.

Thanks for reading!
