03/25/2019 Forecast Update


Monday, March 25th, 2019 through Monday, April 1st, 2019

PM-2.5:  24-hour Fine Particulate concentrations will be generally Good to Low Moderate through the forecast period.


We are looking at a quiet work week on the weather front with generally Good Air Quality.  The first half of the work week will feature high pressure as it tracks southeastward.  Surface winds through Tuesday should be mostly northeast and clean under clear skies.

By Wednesday morning, light winds could allow for the beginning of some localized creep of fine particulates.  By late Wednesday, winds on the back side of the departing high pressure will become southwesterly.  With the advection of warmer continental air, it is a good chance that we will start to experience Low Moderates by Thursday morning.

The models indicate a frontal boundary dropping south through Michigan during the day, Thursday.  The lack of available moisture may cause this front to be mostly dry but some showers could occur.  Winds behind this front will be clean and clear out any Moderate conditions.

A better chance of rain comes Friday night as a stronger system approaches the region.  A chance of snow showers exists during Saturday as temperatures drop.  Winds should be generally from a northern direction with Good Air Quality.


Air Quality is expected to remain mostly Good going into the next work week.
