Temperatures this morning range from the upper 30s to lower 40s around Baltimore to the mid and upper 40s around Richmond and Norfolk. The sky is mostly cloudy with areas of fog begin reported, especially in southeast Virginia. High pressure offshore will create a mild, southerly flow over the region today. Meanwhile, a warm front will move from south to north across the bay this evening, and this will allow even milder air to overspread the area. The moist, southerly flow of air will create considerable cloudiness, fog, and mist as well as unseasonably mild temperatures. Lows by Thursday morning will be around the average high for this time of year (upper 40s.) A cold front will move from west to east on Friday and produce rain across the region From late Thursday night through early Saturday morning. Temperatures will gradually begin to cool from highs in the upper 60s on Thursday, around 60 on Friday, and the lower 40s on Saturday. Cold high pressure builds into the Middle Atlantic region on Sunday morning, sending temperatures below freezing. At the same time, an area of low pressure over the southern states will develop and move toward the area. Moisture ahead of the low will overrun the sub-freezing temperatures at the surface, causing widespread snow, sleet, and freezing rain to develop on Sunday. The exact precipitation type, amount, and duration are yet to be determined, but a prolonged period of frozen precipitation is possible with significant icing in some areas by Sunday night.
