Forecast discussion: We had the chance to see some snow from a low pressure system that formed over the Mid-Atlantic Monday afternoon. However, thanks to high pressure over eastern Canada, it kept the low to our south, giving Washington D.C. six inches, and closing down the federal government. The high will protect us into the middle of the week. Spring will be arriving, but the weekend will feel more like January.
For this evening, the high will settle to our north, allowing for clear skies and calm winds. This will allow temperatures to free fall into the middle teens. This is well below normal for this time of the year. As we move into Tuesday, we will have bright sunshine with temperatures just reaching freezing. We can thank northeast winds coming off the water for keeping temperatures so cold. It will be a little warmer tomorrow night, with lows in the middle 20’s.
We will begin Wednesday with sunshine, but the high’s center will begin to move offshore. A low pressure system moving across eastern Canada will provide us with some showers by Wednesday evening. There will be enough warm air in the atmosphere to keep it as rain showers into the middle of Thursday morning. We will have spring arrive by 12:57 p.m. It will also be the warmest day of the week, as highs climb into the lower 50’s.
By Friday, a new cold front will bring some colder air from Canada back into New England. It will be cold enough for the precipitation to be snow showers before midnight on Friday. By the time we reach the middle of Saturday morning, it will change to rain showers, and remain this way until it ends Saturday evening. After the cold front passes, Arctic air will rush back over the region, and our high temperatures will be well below normal. We will see partly to mostly sunny skies for the start of next week, but temperatures will make it feel more like January than the last full week of March.
