Brian's exclusive forecast for Annapolis: Mostly clear and comfortable overnight with a low in the upper 50s to around 60. Mostly sunny and mild on Tuesday with a high in the lower 80s. Mostly clear but warm on Tuesday night with a low in the low 60s. On Wednesday, the sky will be mostly sunny and it will be warm with a high in the lower 80s. The extended outlook calls for a warming trend later in the week with highs climbing into the lower to middle 80s on Thursday and Friday along with a slight increase in humidity.
Temperatures at 10 p.m. are in the lower 60s around the bay region, but readings will be milder than last night with lows dropping into the upper 50s by Tuesday morning. A broad area of high pressure will provide mostly sunny and pleasant weather for the Middle Atlantic region through the middle of the week. A weak cold front will approach the area from the west, but the front will have little impact on the area other than a few clouds. As the ridge of high pressure moves to our east later in the week, a more southerly flow around the high will bring an increase in both temperatures and humidity. Consequently, on Thursday and Friday we will experience highs in the lower to middle 80s with overnight lows only dropping into the lower 60s. The unseasonable warmth will be broken by a strong cold front that will approach the bay area from the west on Friday.
