Forecast Discussion: Current Conditions: Much cooler air has charged into the area this Monday afternoon on brisk northerly winds, with temperatures some 20 degrees lower than at this point on Sunday. Strong mixing has brought fine particulate well down into the good range. Temperatures will start to rise once again as we move into the mid week period, with a return to above mid-October normals by later in the week. Our sky will clear out tonight with temperatures tumbling into the middle 30s in the colder spots with a touch of frost. *** Tuesday's forecast: Sunshine will prevail across the area during the day Tuesday, with temperatures only recovering to around 60 degrees. Very dry and clean air will remain in place, so fine particulate concentrations remain in the good range. *** Extended forecast: High pressure will continue to control the weather across the area into the latter part of this week. With winds turning more west to southwesterly, temperatures will increase with time, perhaps to near 70 degrees by Thursday. Lighter winds by the mid week period and early morning inversions will bring overall averages for fine particulate back into the moderate range as well.---McAuliffe
