AQI Is Green Across the Board this Wednesday, Thursday

Tuesday, May 26, 2009

Current Conditions: Clouds fill the sky at the present hour, and areas of rain accompany them. We will have periods of rain across the regioninto this evening, and then areas of fog and drizzle later on tonight. This is all courtesy of a stationary front bogged down to our south.With the flow being from the east and southeast, things have really cleaned out, and good air quality will be the rule into tonight. Temperatures this afternoon are stuck in the middle and upper 50s, and will probably hold steady tonight. *** Wednesday's forecast: For the day Wednesday, we see the front will try and lift to the north some. Clouds should predominate, with some morning drizzle, and perhaps a little afternoon sun. Additional areas of rain may then develop later Wednesday and Wednesday night. The flow should remain from the southeast, promoting a continuation of good air quality across the region. Slightly milder Wednesday with high temperatures in the lower and middle 60s.

*** Extended outlook: On Thursday, the front will have lifted to the north, promoting a southerly flow of air. A bit of sunshine from time to time. A couple of showers and a thunderstorm across the area, mainly in the afternoon and evening as a cold front approaches. More humidity might cause PM2.5 levels to increase, but overall, the average for the day should not get out of the good range. Ozone will continue to not be a factor. The cold front will pass east of us on Friday, resulting in a northwest flow. Ozone levels should continue to be good Friday and Saturday. The northwest flow should also keep PM2.5 levels from getting above the good range Friday, though there might some rebound in fine particle levels Saturday when another cold front sweeps through, bringing the chance for a shower. Dry weather is likely most of Sunday as an area of high pressure builds in from the west. Temperatures most of the next several days should average several degrees below normal. Warmer air and some air quality deteriorations are possible early next week as the flow turns more southwesterly
