Forecast Discussion: Current Conditions: Plenty of clouds with associated low level moisture are controlling the weather picture across the region this Wednesday afternoon. A couple of showers and a thunderstorm will also occur over the next 12 hours. With a few breaks of sunshine, ozone levels are increasing some, but these should remain within the good range. Most locations will see fine particulate in the upper good to lower moderate range. Turning out partly to mostly cloudy and humid tonight with areas of fog. Low temperatures mainly in the middle to upper 60s. *** Thursday's forecast: Unsettled weather will continue Thursday with showers and a thunderstorm again likely as low pressure passes just to the north of us. Persistent cloud cover will keep ozone concentrations low, but light winds and high moisture levels will keep fine particulate mostly moderate. Afternoon temperatures will climb into the lower to middle 80s. A fair amount of cloudiness Thursday night with a shower or two still possible. *** Extended forecast: High pressure will extend southwestward at the surface and from the west aloft over the weekend into the early part of next week. On Friday, enough moisture will still be present that we have to allow for a couple of showers. Fine particulate will remain in the moderate range, with ozone continuing in the good range. High pressure then builds further into the area over the weekend, which should turn off the showers. With a east to northeast flow, temperatures will average a little below normal during the daytime, but close to normal at night with possible low clouds and some fog. Overall air quality should be good over the weekend, but as high pressure remains close by early next week, fine particulate and perhaps ozone might deteriorate into moderate territory as winds turn very light, and there is a fair amount of sunshine available for ozone generation.---McAuliffe
