…Weather Summary…

Upper level ridge (hot weather) over the southern Plains will remain in that general area through the week, although it could retrograde a bit. West to northwest flow aloft will continue in the Northland well north of that ridge. The main feature to watch for rain prospects this week is the system over the northern Rockies today, this system moves east/southeast through Tuesday, but could also weaken a bit as it does so, if it weakens enough, then the amount of rain we get around here won’t be very much.

Spotty showers affecting a small part of eastern Minnesota and far northwest Wisconsin this afternoon due in part to a lake breeze boundary will dissipate this evening, otherwise partly to mostly cloudy skies for tonight with patchy fog. Lows in the 50s to around 60, except for a few 40s in the typical cool spots. North or east winds around 10 mph.

Partly to mostly cloudy skies for Monday, not as warm as it has been lately, but not that cool either. Highs ranging from the upper 60s to middle 70s with easterly winds 10 to 15 mph. Some showers could begin to affect parts of north-central Minnesota during the day with the rest of the area possibly getting some rain Monday night. There will be a bit of elevated instability which sneaks into parts of the area Monday night, and this could be enough to ignite a thunderstorm, but not expecting much thunder with this system.

Scattered showers could linger into Tuesday due to a cold front which back doors its way through the Northland, this will kick up the easterly wind on Tuesday with gusts 15 to 25 mph near Lake Superior.

Dry weather returns Wednesday. Highs Tuesday and Wednesday ranging from the lower 60s to lower 70s.

Overall the next several days will be cooler with no more 80s expected in Duluth through Friday (16th) Best chance for rain this week looks to be Monday night-Tuesday, with scattered rains possible later in the week/next weekend.
