A cold front moved from west to east across the bay on Monday and produced widespread rain showers and gusty winds. Some areas received heavy downpours along with isolated severe weather in the form of strong winds and heavy rain. At one point, the region was under a Tornado Watch that expired last evening. Temperatures are significantly cooler today as the wind has shifted to the north. Readings at 3 p.m. this afternoon include 65 degrees at Lake Shore, MD; 65 degrees at Baltimore, MD; 64 degrees at Richmond, VA; 64 degrees at Norfolk, VA; and 66 degrees at Salisbury, MD. These temperatures are about 20 to 25 degrees colder than they were 48 hours ago when the area was basking in 85 and 90-degree temperatures. Looking ahead, low pressure is expected to move northward along the Middle Atlantic coastline and exit off the Virginia shore on Thursday. This low will produce cloudiness and a soaking rain for locations around the bay. The clouds and cool temperatures will hold temperatures down in the low to mid 60s on Wednesday and Thursday. The extended outlook is dependent upon how long the area of low pressure remains in the region. Mostly cloudy conditions may extend into Saturday unless the low begins to move out to sea.
