A warm front will move from south to north across the bay region today. A mild, southerly flow is in place due to high pressure offshore. This has resulted in morning temperatures today and yesterday in the upper 40s to lower 50s. In addition, the moist, southerly flow has produced considerable cloudiness as well as areas of fog and mist. Once the warm front moves to our north, temperatures will surge into the 60s later today (the average high is in the upper 40s.) Meanwhile, 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 as low pressure develops along the front. Temperatures will gradually begin to cool from highs in the upper 60s today, around 60 on Friday, and into the lower 40s on Saturday. Cold high pressure builds into the Middle Atlantic region on Saturday night into 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. At this time, the western shore north of Annapolis could receive one inch of snow followed by several hours of sleet and then freezing rain before the precipitation changes to rain. Consequently, residents should prepare for the potential of power outages and dangerous driving conditions through Sunday evening.
