The National Weather Service’s (NWS) Weather Prediction Center (WPC) is monitoring the potential for a storm system to bring snow to portions of Maryland and the Mid-Atlantic region, including much of Maryland and Virginia, late next week and into the weekend of November 13-15.
While confidence is increasing that a storm system will develop, forecasters emphasize that significant uncertainty remains regarding its track, snowfall amounts, and potential impacts. In a newly released forecast graphic titled “Northeast/Mid-Atlantic Snow Next Weekend?”, the Weather Prediction Center outlined what meteorologists currently know about the developing system and what remains uncertain.
According to the WPC, a wave of low pressure is likely to develop across the Ohio Valley late Wednesday before tracking eastward and strengthening as it moves off the Mid-Atlantic coast on Friday. The system is expected to produce expanding precipitation, with rain and snow possible depending on location and elevation.
Much colder than normal temperatures are also expected to accompany the system Friday and continue through the weekend, potentially creating conditions favorable for snowfall in parts of the region.
The WPC included a probability map showing the likelihood of receiving at least one inch of snow during the period from 7pm Thursday, November 12, through 7pm Saturday, November 14. The map indicates relatively low probabilities across much of Maryland, including Montgomery County and the immediate Washington, D.C. area, with higher probabilities farther north, particularly across portions of Pennsylvania, New York, and New England.
Forecasters stressed that several important details remain unresolved. The exact placement of the storm could significantly change which areas experience rain, snow, or a combination of both. It is also too early to determine how much snow could accumulate, particularly at lower elevations, or whether coastal areas could experience impacts from gusty winds and onshore flow.
“Confidence in storm development is higher than confidence in specific impacts,” the Weather Prediction Center stated, adding that forecast details will change over the next several days.
The update comes as several Maryland and Northern Virginia meteorologists have recently highlighted computer models suggesting the possibility of a November snowstorm. Some of those models have depicted significant snowfall across portions of Maryland, including Montgomery County, although meteorologists have cautioned that such scenarios remain unlikely and are subject to considerable changes.
For now, the National Weather Service is not predicting a major snowstorm for Montgomery County. The latest guidance primarily indicates that a developing storm system and a period of unusually cold weather are worth monitoring, with the potential for accumulating snow remaining uncertain.
Additional forecast updates are expected throughout the coming week as meteorologists gain a clearer understanding of the storm’s track, temperatures, and precipitation patterns.
