01/13/2020 Forecast Update

FORECAST SUMMARY:

Monday, January 13th, 2020 through Tuesday, January 21st, 2020

PM-2.5:  24-hour average Fine Particulate concentrations will be a mixture of Good to Low Moderate until mid-week, then mostly Good through the remainder of the forecast period.

FORECAST DISCUSSION

Following a messy weekend with rain, sleet, snow and ice, a weak upper level disturbance will provide a bit more freezing precipitation through Monday morning. 

High pressure will work into the region Monday afternoon to bring dryer weather and somewhat warmer temperatures.  Southerly winds and warmer temperatures will provide a good opportunity to see a mix of Good to Low Moderate fine particulate readings, especially in the more urban areas. 

The next low pressure system is expected late Wednesday which could provide more mixed precipitation.  A wind shift will also occur providing cleaner air which would push our Air Quality back into the Good category. 

A bigger low pressure system is projected to impact the region starting late Friday and into Saturday.  This looks to have the potential to be significant precipitation event along albeit with continued Good Air Quality. 

EXTENDED FORECAST:

Air Quality should be mostly Good going into the next work week
