area on Tuesday with a cold front moving through the area
Tuesday night. High pressure builds again over the area for the
middle part of next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
High pressure will remain over the Atlantic through Saturday. A
southerly flow around the high will bring much milder conditions
compared to recent days.

ahead of a storm system over the Midwest. Mid and high clouds
will hang around for Saturday as well...but there will be some
breaks of sunshine. A backdoor cold front will approach the area
late in the day. A few showers may pop up ahead of the front
Saturday afternoon...especially across northern and central
portions of the CWA. Even across these areas...much of the time
will be dry and any shower coverage will be widely scattered due
to limited instability. Max temps Saturday will top off in the
70s across most locations.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
On Sunday, a backdoor cdfnt could push south into southern MD
