12/4/2023 Forecast Update

FORECAST SUMMARY: MondAY, December 4, 2023, through FRIDAy, December 8, 2023

PM-2.5:   24-hour average Fine Particulate concentrations are also expected to be Good to Low Moderate.

FORECAST DISCUSSION:

A departing low pressure provided early Monday morning showers which will diminish during the day as drier air enters the region with a short-lived high pressure ridge. 

A clipper system is expected by the Tuesday morning time frame bringing additional precipitation.  Tuesday temperatures are expected to reach the upper 30’s so any morning snow showers will quickly become rain showers. 

By midweek, an upper air high pressure ridge should push out any lingering wet weather and position the state in a strong southwest wind pattern.  Thursday’s temperatures are expected to reach the mid-40’s and Friday’s temperatures could reach the low-50’s with breezy winds.

Air Quality should remain mostly Good but could reach the Low Moderate range in some areas with the warmer temperatures and ample moisture.

More precipitation may be on the horizon during the weekend and that chance will be discussed in the Friday forecast.

 

EXTENDED FORECAST:

Air Quality should be generally Good to Low Moderate entering the weekend.
