Tomorrow’s Forecast
Thursday, Nov 24:102 AQIUnhealthy for Sensitive GroupsParticle Pollution (2.5 microns)
Extended Forecast
Friday, Nov 25:75 AQIModerateParticle Pollution (2.5 microns)
Saturday, Nov 26:50 AQIGoodParticle Pollution (2.5 microns)
Sunday, Nov 27:39 AQIGoodParticle Pollution (2.5 microns)
Monday, Nov 28:34 AQIGoodParticle Pollution (2.5 microns)

Current Conditions: A strong high pressure system over the Mid-Atlantic states is producing sunny skies and mild air this Wednesday afternoon. A morning inversion resulted in elevated fine particle (PM-2.5) levels, and limited mixing this afternoon is keeping overall PM-2.5 in the moderate range. Tonight, another inversion will develop, and fine particle pollution will tend to get trapped close to the surface once more. *** Thanksgiving Day forecast: An Air Quality Action Day will be declared for the day Thursday!! PM-2.5 will end up being highest prior to noon, with slightly better air quality during the afternoon. PM-2.5 concentrations will reach code ORANGE, especially in and around the Lancaster area. Otherwise, skies will be mostly sunny with a mild afternoon. *** Friday’s forecast: A weak cold front will bring more clouds and rain showers to the region Friday. PM-2.5 concentrations will still be elevated during the morning Friday, but increasing afternoon west to northwest winds should keep average concentrations down in the moderate range.

A strong inversion is likely to increase particles again tonight. *** Sunday’s forecast: An Air Quality Action Day will be declared for Sunday! High PM2.5 levels during the morning hours Sunday will send daily averages into the code ORANGE range, mainly across Lancaster County. The highest PM2.5 will come prior to 11 a.m. Sunday morning. A light northeast wind will improve air quality during the afternoon. *** Monday’s forecast: PM2.5 will continue to be an issue as we move into the new workweek. Light south to southeast wind will again not allow for a good deal of mixing, so high moderate air quality is again likely. *

Air Pollution Kills 10 Million People a Year.

For every thousand people alive on earth, 973 are regularly inhaling toxins. Only 27 are not. Which means, almost certainly, you are too.

Last fall, the World Health Organization lowered its global air quality standard from 10 micrograms of particulate matter per cubic meter to five. Those terms and standards can feel abstract, which makes their meaning a bit hard to fathom.  Read more . . .

DEP declares Orange Air Quality Action Day for Thursday, Jan. 13, 2022

DEP Declares Code Orange Air Quality Action Day for Fine Particulate Matter for Thursday, January 13, 2022, in Multiple Areas of Pennsylvania

Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) has declared a Code Orange Air Quality Action Day for fine particulate matter for Thursday, January 13, 2022, in the following areas of Pennsylvania:

• The Philadelphia Area, which includes the counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia;
• The Lehigh Valley-Berks Area, which includes the counties of Berks, Lehigh, and Northampton; and
• The Susquehanna Valley Area, which includes the counties of Cumberland, Dauphin, Lancaster, Lebanon, and York.

A moderately strong temperature inversion Thursday morning with calm or very light wind will likely contribute to daily average concentrations of fine particulate matter in the Code Orange range.

The U.S. Environmental Protection Agency’s (EPA) Air Quality Index (AQI) provides standardized color codes for forecasting and reporting daily air quality. Green signifies good air quality; Yellow means moderate air quality; Orange represents unhealthy pollution levels for sensitive groups of people; and Red warns of unhealthy pollution levels for all.

An Air Quality Action Day is declared when the AQI is forecasted to be Code Orange or higher. On an Air Quality Action Day, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.

Residents and businesses within the Air Quality Action Day areas are strongly encouraged to voluntarily help reduce fine particulate matter air pollution by:

• Reducing or eliminating fireplace and wood stove use;
• Avoiding the open burning of leaves, trash, and other materials; and
• Avoiding the use of gas-powered lawn and garden equipment.

DEP extends air quality action day to July 21

Harrisburg, PA.  An Air Quality Action Day for fine particulate matter will be in effect once again in the Susquehanna Valley for Wednesday, July 21. A cold front pushing to the south and east will improve conditions and help to move the wildfire smoke out of the area, but this feature will not arrive until the afternoon to early evening hours. A slight chance for showers and possibly a few thunderstorms will occur in advance of the arrival of this front, but these will not be widespread enough to help to clean out the air prior to the frontal passage.
