Fog will continue to burn off through the morning hours giving way to sunny skies throughout the afternoon however the moisture will stick around making the afternoon quite humid.
Warm temperatures and humid conditions Sunday afternoon will allow the chance for a stray shower or thunderstorm to develop this afternoon. Any storms that develop will be fairly isolated meaning many areas may not see any rain what so ever.
Better chances for more widespread, heavy rain moves in late Monday and continues as a cold front moves through Tuesday morning. Behind the cold front cooler and more comfortable conditions move in.
