    Low temps are in the upper 30s tonight in Duluth. Expect low 30s in the Iron Range and Grand Marais. We have mid 30s for the South Shore, U.P., Hayward, Aitkin and International Falls. A warm front passes through tonight giving us clouds and a 20-30% chance of some scattered sprinkles.

    The jet stream is in a ridge pattern over the region. This allows us to dry up and clear up throughout our Saturday. It also allows for the warm air to arrive and stick around. You can think of the jet stream as a border between the colder air and warmer air. So we are on the warm side of the jet for Saturday. High temps are in the upper 50s for the Iron Range, South Shore, Hayward and Aitkin. Duluth and Ironwood are in the mid 50s and International Falls sees the low 50s with more cloud coverage. In fact the Borderland and Grand Marais will see mostly cloudy skies as the warmer air rises above the colder air to the north in Ontario creating clouds.

    Then Sunday the jet move into a trough pattern over the area which will give us a chance of showers and will cool us down a bit. High temps are in the low 50s and there’s a 30% chance of showers, mainly north of the Twin Ports.

    Monday a large high pressure system works its way east over the region. As it settles our atmosphere we have a chance of patchy fog in the morning hours. The fog should dissipate by mid morning and allow for sunny skies. Lows are in the low 30s and highs are near 50.

    Tuesday there’s a low to our south. Current trends keep the low too far south to warrant a big chance of rain. Will go with a 20% shot mainly south of the Twin Ports just in case. Lows are in the upper 30s and highs get up to 51. Tuesday night into Wednesday morning will be our best chance of showers, at around 30%. Then we cool off a little Wednesday with lows in the low 40s and highs in the upper 40s.

    Have a great weekend!
