WASHINGTON (WUSA9) -  The atmosphere will remain unstable Thursday. A cold front will approach from the west triggering another round or two of showers and T-storms. We'll see some  morning showers as well as afternoon and evening showers and T-storms. 

The strong cold front moves through the Metro Area late Thursday night along with much cooler air. Friday will see some late clearing with spotty showers that will be tapering off Friday afternoon. The Memorial Day weekend looks rather brisk. Highs will struggle to reach seventy Saturday with lows in the forties in the suburbs Friday and Saturday night.
