Today's weather featured abundant sunshine and mild temperatures. Morning lows were quite chilly with thermometer readings in the mid 20s from Baltimore to southern Maryland to the Tidewater area of Virginia, but readings climbed through the 30s and 40s during the late morning and afternoon hours. Highs reached the mid 40s to around 50 degrees with the coolest temperatures right along the shore of the bay where the cold waters impact the ambient temperature. High pressure over the southern states will continue to impact the Mid-Atlantic overnight with cold temperatures as readings will fall back to the upper 20s to lower 30s by Saturday morning. The center of high pressure will shift to our southeast on Saturday, and this will create a more southerly flow across the region. As a result, many locations around the bay will experience highs on Saturday in the 50s. Meanwhile, low pressure near the Gulf of Mexico will move northeast and produce widespread rain showers over the area through the day on Sunday. The precipitation will be all rain from beginning to end due to the lack of cold air in the northeast. Only places in the mountains to our west may see the rain mix with, or change to, snow before ending on Sunday. As we look ahead to next week, cold high pressure will dominate the weather map in the East and temperatures will turn colder with daytime highs all of next week only in the 30s.
