Pleasant weather conditions will be found across the Northland on Saturday with highs mainly in the 50s which is right where we should be in mid-April. Some changes take place from NW-SE on Sunday as a low pressure system and a pretty strong cold front approaches from the NW, this system will lead to increasing cloudiness during the day Sunday which will be followed by some rain showers to start during the afternoon-early evening, and then a few flurries and snow showers for Sunday night and Monday. Note: The best chances for a light coating of snow accumulation looks to be across northern Minnesota where a half inch to two inches of snow is possible Sunday night (north of Duluth)
We should be able to squeeze out one more mild day on Sunday prior to the passage of a cold front, with highs on Sunday ranging from the 40s near the Minnesota/Ontario border, to the low 50s to around 60 degrees across northeast Minnesota and northwest Wisconsin.
