Canadian high pressure developed over the Middle Atlantic region today with cold temperatures as highs only reached the mid to upper 30s after morning lows in the mid to upper 20s. There was plenty of sunshine today, but thermometer readings ran about 15 degrees below seasonal averages of 50 degrees. Meanwhile, an area of low pressure is developing to our south and will move up the coast on Friday. The majority of the precipitation from this system will impact southeast Virginia, southern Maryland, and coastal Maryland and Delaware; however, some precipitation will likely make its way northward to Annapolis and Washington. Depending on the arrival of the moisture, temperatures may be cold enough at the surface to produce a brief period of mixed precipitation on Friday in the form of light sleet or freezing rain. Some light snow is possible in the Richmond VA area as well. As the storm brings in milder air from the Atlantic, all precipitation will change over to rain. Rain showers will continue through Friday night and into Saturday morning, with the heaviest rain to the south and the east. Temperatures will be chilly on Friday with the falling rain, but readings will be above freezing with highs in the lower 40s. As the storm pulls away from the coast on Saturday, a milder pattern will become established. The period Sunday through Tuesday will feature sunshine and moderating temperatures with highs in the upper 40s on Sunday and the upper 50s on Monday and Tuesday. Looking ahead to later next week, a cold front will produce rain showers on Wednesday with colder temperatures as highs drop from the upper 50s on Tuesday to the upper 40s on Wednesday. A storm system may impact the region later next week with rain and/or snow.
