03/31/2025 Forecast Update

FORECAST SUMMARY: Monday, March 31, 2025, through Friday, April 4, 2025

  OZONE: 8-hour average Ozone concentrations are expected to be Good (AQI Green).

 PM-2.5:  24-hour average Fine Particulate concentrations are expected to be a mixture of Good (AQI Green) to scattered Low Moderate (AQI Yellow).

FORECAST DISCUSSION

The weekend turned out to be quite wild with the ice storm up north and severe weather in the south.  I have read that six Michigan counties have over 80% power outages, Monday morning, between the two storms.

 This work week starts out quiet, but cooler, following the passage of a cold front but it looks to get bumpy again during mid-week.  Tuesday night model results suggest precipitation starting as all snow changing over to rain by daybreak south of I-96. North of I-96, surface air stays cold longer with accumulating snow and freezing rain likely.

 As Wednesday progresses, we get into a warm air sector ahead of the front with afternoon temperatures increasing into the 60’s.  Atmospheric instability will become significant with the increasing possibility of severe weather by late Wednesday.  Current models have an Enhanced Risk of severe weather (Level 3/5) south of I-96 with a Slight Risk (Level 2/5) north of I-96.  Precipitation models have rain potentials of 1-2 inches with more likely in thunderstorm downpour areas.

 Air Quality will not be an issue in this week’s forecast.  PM-2.5 will be a mix of Good to scattered Low Moderate.  Ozone once again becomes part of our forecast as we enter into April with concentrations expected to be Good.

  EXTENDED FORECAST:

 Air Quality is expected to be mostly Good to scattered Low Moderate going into the upcoming weekend.
