Forecast Discussion: Current Conditions: A brisk northwesterly flow persists across the region this Friday afternoon, but with more in the way of sunshine, the air feels a little better than on Thursday. Despite the sunshine, temperatures are not budging past the lower 50s, still 10-15 degrees below normal for this point in April. The brisk winds mean fine particulate levels continue to be on the low side. Winds will come down some tonight as high pressure continues to build. Frost and freezing temperatures are likely in many areas, with lows in the middle to upper 20s in the colder valleys. *** Saturday's forecast: Saturday will start out sunny and cold, but clouds will increase by the afternoon. Very dry air at the surface will keep any precipitation late in the day from reaching the ground, and it will also keep PM2.5 concentrations low. Afternoon temperatures recovering to the middle 50s. A storm coming across the southern Ohio valley will then bring a little rain Saturday night into Sunday morning. *** Sunday's forecast: A bit of rain will start the day on Sunday, then the sun will return by the late afternoon. North to northeast winds will keep fine particulate down in the good range. High temperatures will reach near 60. Chilly with a clear to partly cloudy sky Sunday night as lows dip into the upper 30s. *** Monday's forecast: A new area of high pressure builds southward from Ontario, Canada on Monday. Adequate mixing from northerly winds will bring PM2.5 concentrations to low levels. Temperatures in the afternoon with sunshine should reach near 60 degrees once more. *** Extended forecast: High pressure remains in control of our weather Tuesday, with lighter winds and highs reaching into the middle 60s. Fine particulate will rise, perhaps into the moderate range in a few areas. The best chance for moderate levels of PM will be on Wednesday as winds will be very light and we are in between weather systems both to the north and to the south.---McAuliffe
