Michael Fish's NBC 26 weather forecast

Memorial Day, expect the warmest temperatures of the holiday weekend. We will rise into the low/mid 80s with some isolated afternoon showers and thunderstorms. Dew points will be well into the 60s making it a little humid. A marginal risk of severe weather is highlighted north and northwest of the Fox Valley. Some of the storms may produce a little gusty wind or small hail. A chance of isolated to scattered thunderstorms will continue Tuesday, Wednesday, and Thursday. Highs in the upper 70s and lower 80s. The reason due to this continued risk of storms lays with a strong blocking high pressure over the Atlantic. This high is causing a ripple effect on storm systems moving through the Midwest, slowing their progression. Eventually this block will degrade and by Thursday evening, we will end the risk for storms. Temperatures will fall into the lower 70s Friday with mostly sunny skies. Some cooler air moves in for the weekend with highs in the upper 60s Saturday and lower 70s Sunday
