Break from rain around the corner

Highlights

  • Chance of Precipitation early/mid-day Wednesday
  • Rain chances diminishing throughout the week
  • Temperatures returning to near normal

The three day totals for the previous precipitation event has taken a toll on the waterways of Kentucky, with many counties including Warren County currently under a flood warning.  Remember to not try and cross flooded roadways and passages.  A graphic provided by the National Weather Service shows the rain distribution totals from December 4th-6th.

A high amplitude trough transitioning to a negative tilt, which signifies a trough reaching maturity, will quickly race across the region, bringing with it a chance of precipitation early Wednesday.  A mix bag of precipitation cannot be ruled out, but accumulations will be minimal, most likely less than a tenth of an inch.

Passing of the trough will bring about clearing skies and sunshine in the afternoon with highs reaching in the mid 40′s, and lows falling into the mid 30′s.  Thursday will bring about mostly sunny skies in the mid 40′s with lows becoming quite chilly in the mid 20′s under the influence of cold air advection by the passing of the trough and radiative cooling under clear skies.

An update for the weekend will come on Thursday.
