The Lehigh Valley/Berks Area Air Quality Forecast for:
Wednesday, March 12, 2008:
Fine Particulates (PM 2.5) – Code YELLOW
Regional Maximum PM 2.5 Concentrations:
Monday, March 10, 2008:
PM 2.5 – YELLOW (64 AQI or 21.9 µg/m3)
Short-Term Discussion: Some scattered clouds across the forecast area at the moment with fine-particulate concentrations currently in the moderate range. Clouds will increase this evening as another weak low-pressure area drops out of the Great Lakes overnight. Temperatures are forecast to remain above freezing so frozen precipitation should not be a problem except to our north.
Cloudy overnight with a possible shower or maybe even wet snow in a few spots; lows will be in the low to mid 30s. Cloudy in the morning with a left over sprinkle in spots, then becoming partly sunny and breezy with afternoon temperatures expected to reach the upper 40s. Wednesday’s fine-particulate concentrations should fall as northwesterly winds pick up but still remain in the code YELLOW (moderate) range for portions of the forecast area.
Extended: The second in a series of weak low pressure systems will pass through our area Wednesday morning with another to follow early Friday morning. Don’t expect much precipitation from either of these systems though with temperatures slowly rising over the remainder of the week, the threat of nuisance snow is diminishing. With a series of weak weather systems affecting us and no real “clean out” appearing to take place air-quality readings will probably remain in the moderate range over the next several days.
