Temperatures this afternoon are mild for the middle of August with low 70s being reported at most locations. A cloudy sky overhead is holding temperatures down, along with scattered rain showers which are impacting areas of southern Maryland into southeast Virginia. The precipitation is fairly light, although there may be a few moderate showers embedded in the field of rain. The southerly flow that is producing these conditions will be replaced by high pressure building over the Middle Atlantic region on Tuesday. The result will be a mostly sunny sky and much warmer readings with highs in the mid to upper 80s in Annapolis. Overnight lows will only fall back into the upper 60s to lower 70s by Wednesday morning. During the day on Wednesday, we can expect a mostly sunny sky with a high in the upper 80s.
On the Maryland portion of Chesapeake Bay, a Small Craft Advisory is currently in effect through the afternoon. Winds today will shift to the south at 10 knots or less with wave heights of 1 foot or less. Marine weather information is provided only as a guide. Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.
