CLOUDY AND COOL WITH A FEW ISOLATED LIGHT RAIN SHOWERS
-Upper level low pressure now centered over SW CO this morning will track NE'ward through the day keeping conditions cloudy and cool over the District with a few isolated rain showers for the plains and a mix of rain and snow for the foothills pending elevation.

-Isolated light rain showers below 7,000ft will be possible through the day today and into the evening although the majority of the time will be dry. Over the foothills above 7,000ft precipitation will likely favor snow or a mix of rain and snow but no meaningful snow accumulations are expected, mainly just a trace.
-After midnight tonight conditions look to be drying out with temperatures falling into the mid and upper 30's over the plains with upper 20's and lower 30's in the foothills.

A LOOK AHEAD: On Friday conditions will be dry over the District with with sunny to mostly sunny skies returning temperatures will be able to warm into the upper 60's and lower 70's over the plains.
