Brian's exclusive forecast for Annapolis: Sunny and warm but pleasant today with a high around 80 degrees. Light and variable winds. Clear tonight with a low in the upper 50s to lower 60s. Near calm winds. Clouds and sun on Thursday with a high in the lower 80s. Clear and cool Thursday night with a low in the mid 50s. North winds 10 to 20 mph at times.

High pressure will build over the Middle Atlantic states today. We are already feeling the impact of the high as thermometer readings have dropped into the upper 50s to lower 60s this morning. Under bright sunshine today, we can expect afternoon readings to climb into the low 80s with a light breeze from the northwest. A second frontal system will bring some clouds to the area on Thursday, but there will still be some sunshine with a high in the lower 80s. Behind the second front, cooler air will overspread the region so that by Thursday morning we will be recording temperatures in the middle to upper 50s. The cooler temperatures will be accompanied by a northerly breeze of 10 to 20 miles per hour at times. During the day on Thursday, highs will only climb into the mid 70s making it the coolest day since early summer. Looking ahead to the weekend, we can plan for a mostly sunny sky on Saturday and Sunday along with a warming trend as temperatures slowly climb through the 80s. Clouds may roll overhead later in the weekend as a cold front approaches the bay region.
