The first day of October felt more like early September around Chesapeake Bay with afternoon highs in the low 80s at Baltimore and the mid 80s at Richmond, Virginia. Unseasonably warm weather is expected to continue through the rest of the week. A broad area of high pressure will provide mostly sunny and warm weather for the Middle Atlantic region through the end 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. Slightly cooler temperatures will return this weekend, but readings will remain above seasonal averages with highs in the upper 70s each day.
