Brian's exclusive forecast for Annapolis: Mostly clear overnight with a low in the low 60s. Light northeast wind less than 10 mph. Mostly sunny, cooler, and less humid on Monday with a high in the mid 70s. North/northeast winds around 10 mph. Clear on Monday night with a low in the mid 60s. On Tuesday, look for a mixture of clouds and sun. It will be much warmer with a high in the mid to upper 80s. The outlook for Wednesday calls for hot and humid conditions with a high in the upper 80s to lower 90s.
A cold front will move through the area overnight and usher in cooler and less humid air by morning. High pressure will provide the area with a sunny and pleasant Monday with highs only in the mid 70s. However, the center of high pressure will move offshore and a southerly flow around the high will result in a dramatic increase in temperatures and humidity by the middle of the week with highs increasing to the mid to upper 80s on Tuesday and the upper 80s to lower 90s by Wednesday. Although skies will be mostly sunny both days, there is a chance of an afternoon thunderstorm. Later in the week, a strong cold front will push across the Chesapeake and open the gates for significantly cooler air by Friday with highs only in the 70s and overnight lows in the 50s.
On the Maryland portion of Chesapeake Bay, a Small Craft Advisory is in effect through Monday morning for winds gusting to 20 knots from the east/northeast and for waves of 1 to 3 feet.

Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.
