Sunday is a little warmer than Saturday but still below average for this time of year, especially near the lakes.
Sunday's highs will mainly be in the low to mid 70s but only into the 60s near the lakes. Skies will be partly to mostly sunny under high pressure, but some clouds will slowly move in from the west as the day progresses.
As winds pick up out of the south, Sunday night's lows will only fall into the 50s, much milder than Saturday night's lows. Skies will become mostly cloudy, and there is a chance for some thunderstorms and rain showers, mainly over the western and central counties, as a warm front approaches the U.P.
That warm front will bring Monday's highs back up into the upper 70s and low 80s. Thunderstorms are likely much of the day across Upper Michigan. Conditions will also be windy.
Monday night's thunderstorms are likely to be stronger along a cold front as it sweeps eastward overnight. Lows will be in the 50s or cooler behind the front. After the cold front passes, conditions should be much clearer.
Tuesday will again be cooler with many highs struggling to get above 70, but skies should be mostly sunny by afternoon. Much of the upcoming week looks to have seasonable temperatures or perhaps a little cooler. The next day that may see storms is likely to be Thursday.
On a non-weather-related note, did you catch part one of my series called "Brewing Up Business?" The link is below. The craft beer industry is skyrocketing in Michigan. Part two airs Monday on the News Tonight.
