Current Conditions As of 2 PM on Monday: Surface high pressure is located off the New England Coast allowing for more of a cool, maritime, east to southeast wind today keeping temperatures down in the low 60’s. A combination of light wind flow, and continue lack of moisture/rain, will promote PM2.5 levels in the high-good to low-moderate range, with low-moderate most likely in the morning hours. *** Tuesday’s forecast: As a warm front passes well to the north, it is expected to turn warmer into the mid-70’s with a south to southwest wind on Tuesday allowing for adequate mixing to create mostly good PM2.5 levels. *** Wednesday’s forecast: The next cold front then approaches Wednesday. Once again, this front does not look like it will produce much needed rainfall. Increasing mixing with a northwesterly wind will lead to good air quality Wednesday and Thursday. ---VanLenten
