MEANWHILE, DOWNEAST AND CENTRAL MAINE IN A D1 MODERATE DROUGHT, AND NORTHEASTERN MAINE IN D0 ABNORMALLY DRY. THE NORTH WOODS REGION IN NORTHWESTERN AROOSTOOK WAS THE ONLY DROUGHT- FREE REGION AT SUMMERS END. FOR THE NEXT SEASONAL OUTLOOK GIVEN BY THE CLIMATE PREDICTION CENTER (CPC), LOOKING AT AN ELEVATED RISK OF ABOVE AVERAGE TEMPERATURES FOR METEOROLOGICAL FALL (SEPTEMBER THROUGH NOVEMBER). THERE IS NOT A STRONG SIGNAL FOR ABOVE OR BELOW AVERAGE PRECIPITATION FOR THIS TIME FRAME, HOWEVER. TYPICAL AVERAGE TEMPERATURES IN THE CARIBOU AREA ARE IN THE 50S IN SEPTEMBER, 40S IN OCTOBER, AND 30S IN NOVEMBER. FROST DOES START TO BECOME A CONCERN BEGINNING IN SEPTEMBER, AS OVERNIGHT LOWS BEGIN TO CREEP DOWN TO BELOW FREEZING. SNOW IS EXPECTED TO BEGIN TO FALL IN METEOROLOGICAL FALL. NORMAL AMOUNTS OF SNOW IN THE CARIBOU AREA BEGINS IN OCTOBER, WITH TYPICALLY ONLY 1-2 INCHES FALLING, AND NOVEMBER TYPICALLY SEEING UP TO 10 INCHES BAKED ON CLIMATE NORMALS. $$ ASB/NC $$
