Updated at six zero seven P.M. Central Daylight Time Tuesday October twenty-seventh twenty twenty-six. Warm, sunny days and cool, clear nights will continue through the work week. No rain is expected through at least Friday night, but the weather pattern will begin to shift this weekend. Drought conditions will continue to worsen in the near-term. Highs in the low to mid-seventies across Middle Tennessee... Minimum relative humidity thirty-five to forty percent... Patchy early morning fog... Mid-forties to low-fifties... The large upper ridge continues to dominate the continental United States. A dry air mass sitting still over our houses. A lack of wind mitigates the fire weather concerns for now. Quiet afternoons bleeding into cool clear nights. Status quo through the rest of the work week. No precipitation through Friday night! But the upper ridge starts to break down this weekend! Opening the door! Opening the door! Rain chances increase Saturday morning! A broad quantitative precipitation forecast range! Appreciable rainfall probable at last! The pressure drops and the pattern shifts! Everything peaks on Sunday! Peak on Sunday! DROUGHT CONDITIONS CONTINUE TO WORSEN! UNTIL THE RIDGE BREAKS DOWN! PEAK ON SUNDAY! PEAK ON SUNDAY! Additional rounds of precipitation possible... Early next week... Peak on Sunday...
