The National Weather Service Baltimore Washington Forecast Office has just issued a\u00a0Winter Storm Watch<\/strong><\/a>\u00a0from Monday evening through\u00a0Tuesday afternoon of this week. The storm could dump 5 or more inches of heavy wet snow within a 12 hour period. Potential storm impacts include power outages, broken tree limbs, slippery conditions, and messy roads.<\/p>\n

Which locations will be getting snow on Monday and Tuesday? How much snowfall can we expect? Well, all eyes are still on the potential set-up for Monday\u2019s developing Nor\u2019easter. We are tracking two systems. One low will be approaching the mid-Atlantic region from the Mid-West. Another developing low-pressure system will track along the coast. It will usher in a chilly northeasterly flow of 10-15 mph winds with up to 25 mph gusts. By Tuesday morning, these two systems will merge and produce impactful wintry weather for the Northeast region. Keep in mind there is still a lot of uncertainty for snow totals and the positioning of the storm. The uncertainty leaves behind low confidence for the exact position of the rain-snow line within the DMV area. The position of the rain\/snow line could shift more snow south and east of DC or it could shift more rain and mix north and west of DC.<\/p>\n

Tuesday Morning:\u00a0<\/strong>Now, here\u2019s when we will face the greatest potential for heavy snow. By 7 a.m., the GFS predicts heavier snowfall patterns for locations west of Washington, DC and throughout most of Northern Maryland and Virginia. The model positions the low just off the coast of Eastern Maryland. As you can see, the rain-snow line extends in a slight southwest-northeast direction just south and east of the District. Portions of Prince Georges County and further east could experience less snow and increasing chances for rain showers.<\/p>\n

The National Weather Service predicts that there will be a 65% chance of 6 inches of snow or more for the DC\/metro area (see image below).<\/p>\n
