Forecast Discussion

Monday, March 27, 2017, 10:30 AM

Synopsis: The sun won't be making much of an appearance Monday and Tuesday, with low clouds, low ceilings, chance of showers, and light winds. Highs in the 40s both days. The low cloud decks and light winds should be enough to create poor mixing and allow fine particles to reach MODERATE later on Monday and into Tuesday. By Wednesday, low pressure passes offshore and high pressure builds in with north winds, sunny skies, and GOOD air quality lasting into Thursday. Sun will allow temperatures to near 50, but dry and cool with steady winds.

 

Air Quality Guide for Particle Pollution

Air Quality Index Levels of Health Concern Numerical Value Meaning
Good 0-50 Air quality is considered satisfactory and air pollution poses little or no risk.
Moderate 51-100 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups 101-150 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy 151-200 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
