Updated at ten twenty-seven P.M. Central Daylight Time Saturday October seventeenth twenty twenty-six. Patchy frost overnight, especially for the Upper Cumberland. Cool nights and mild days through the week. Highs mainly in the seventies, maybe some lower eighties late week. Dry pattern for the rest of the month with drought conditions worsening. High pressure locked in across the entire region Zero moisture in the atmospheric legion Wake-up temperatures dropping fast down low Upper Cumberland watching the frost start to show Clear skies light winds mercury down to the floor Upper thirties knocking on the front door Mid sixties to seventies on Sunday afternoon Picture perfect autumn under a clear moon No moisture loading in the column tonight Precipitable water nowhere in sight Tension building up under the high dome Cold ground waiting in our southern home Dry air static in the atmosphere No cloud cover to disappear Cold dawn breaking high pressure near Sky stays clear Monday morning repeating the exact same frame One or two degrees warmer in the forecast game Model guidance projecting out as far as we scan No rain coming for the working man Gradual warm up pushing through the mid week stride Lower eighties lurking on the late week side Fire risk rising as the fuel beds bake Light winds saving every breath we take FROST! Drought conditions worsening! Nothing in the model! Nothing on the radar! Dry! Dry! Dry! Upper Cumberland frost. Seasonably cool. No rain coming. Sky stays clear.
