Our weather has transitioned from record warmth three days ago to conditions more representative of late December. Afternoon thermometer readings are currently below freezing at many locations around the Chesapeake Bay. After morning lows dipped into the upper 10s to lower 20s, current temperatures at noon include 29 at Lake Shore MD, 27 at Baltimore MD, 32 at Salisbury MD, and 31 at Richmond VA. High pressure overhead will ensure a sunny but cold afternoon with maximums only rising a few more degrees. Winds are much lighter compared to this time yesterday, although actual temperatures are about ten degrees colder. Tonight, the wind will shift to the south and this will prevent temperatures from falling all that much. Thursday morning lows will only drop into the mid to upper 20s and readings will rebound into the lower 40s by Thursday afternoon. Later in the week, a weak cold front will whisk across the bay from west to east on Thursday evening. Other than a brief snow flurry or rain shower, the frontal passage will be uneventful. Temperatures behind the front will be a bit cooler so that highs on Friday will be in the upper 30s to lower 40s. Weekend highs will moderate into the upper 40s on both Saturday and Sunday before the next cold front moves through the region.
On the Maryland portion of Chesapeake Bay, no advisories are in effect. Winds today will come out of the north at 10 knots, then shift to the south later this afternoon. Waves will be around one foot. Winds tonight will come out of the south at 10 knots with waves around one foot. Winds on Thursday will come out of the west at 10 knots with waves around one foot. Winds on Thursday night will come out of the northwest at 10 knots with waves around one foot. Winds on Friday will come out of the west at 10 knots with waves around one foot. Marine information is provided as general guidance. Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.
