Forecast Discussion: Current Conditions: Breezy conditions prevail across the area in the wake of a cold front this Monday afternoon. With some sunshine returning, temperatures are moving into the lower 50s. Good air quality will continue over the next couple of days with a progressive pattern, then winds will shift into a southwesterly direction with warmer air coming later on this week with deteriorating air quality. Partly cloudy and chilly tonight with lows close to 30. PM2.5 concentrations will be in the good range. *** Tuesday's forecast: Rather cloudy Tuesday with an area of low pressure moving off just to the north of us. This will mean periods of rain and rain showers with highs struggling to get out of the middle 40s. Adequate mixing with the precipitation will keep PM levels in the upper good range. Mostly cloudy Tuesday night with perhaps a rain or snow shower early on. Lows will drop to the upper 20s. *** Extended forecast: Chilly air will hang on for the middle of this week, then southwesterly winds will bring some warming later on. With the warming, PM2.5 levels will rise. High pressure will bring mostly sunny skies for Wednesday with highs in the upper 40s. Very dry air will surpress PM2.5 to the good range. Southwest winds by Thursday could send temperatures into the lower 60s, and with humidity also increasing, moderate air quality is likely. A cold front will then approach the area by Friday, with rain late in the day and at night. Moderate levels of PM2.5 will continue. The front will then stall and a wave of low pressure form along it late Friday night into Saturday with more rain possible. Heavier precipitation will then send PM levels down to the good range once more. Easter Sunday looks to be dry with good air quality, but temperatures will be a little below average in spite of the sun returning.--McAuliffe
