Forecast Discussion: Current conditions: At 2 p.m. EDT this Wednesday afternoon, high pressure over Ontario, Canada has brought sunshine for the most part with a seasonably cool afternoon. Plenty of mixing and dry air have kept PM2.5 concentrations down into the good range. Tonight will start off clear, but then clouds will increase overnight. Low temperatures falling back to the upper 30s. *** Thursday's forecast: Mostly cloudy Thursday with rain arriving in the afternoon as low pressure moves eastward out of the nation's midsection. Enough mixing should exist to where fine particulate remains in the good range. Highs in the lower to middle 50s. Breezy Thursday night with periods of rain. *** Extended forecast: Low pressure tracking just to the north and west of us will bring more rainfall to the area Friday, and rainfall should maintain good air quality for the day. Low pressure north and west of us will weaken Friday night and a new low will develop off the Delmarva peninsula This will taper the rain to just showers. Surface flow will turn into the north and northwest Saturday, but plenty of clouds will remain with a couple of showers. Enough mixing should promote PM2.5 in the upper good range. High pressure will bring more tranquil weather Sunday into early Monday, then another storm is slated to affect the area with another round of rain late Monday into Tuesday of next week.---McAuliffe
