Today was officially a record warm day in Flint with highs hitting 74° breaking the previous record of 73° set back in 1928. Tomorrow will be far from record breaking.
Rain becomes widespread through the morning hours with a chance for some heavy pockets of rain. Widespread rain stays with us most of the morning south of the Saginaw Bay. Highs will be in the mid to the upper 30's with some southern areas (i.e. Flint) could hit 40°+.
Some areas north of the Saginaw Bay can see a rain/snow mix on a cold, wet and raw kind of day.
Sunday will bring another spread in temps (cooler north in the 40's, warmer south in the 50's) with more on and off rain showers and even a few rumbles of thunder.
Some light rain showers can still stick around Sunday night but we should be dry Monday which is looking like the warmest day of the week.
