Weather Summary

The National Weather Service has issued a Winter Weather Advisory through 8 p.m. this evening for snow. At 7 a.m. radar is showing a wide area of snow developing just to the south and west of Washington DC. This snow will move to the north and northeast, overspreading Baltimore and Annapolis during the morning hours. Temperatures are in the mid to upper 20s this morning, so the snow will likely begin to accumulate. During heavier bursts of snow, roads may also become temporarily snow-covered and slipper. However, the high March sun angle will result in mostly wet roads this afternoon. The energy producing today's snow will combine with a developing area of low pressure off the Atlantic coast today, the latter of which will become a powerful nor'easter. As the coastal low intensifies, winds will begin to pick up across central Maryland later today and into the evening hours. The low will be far enough off the coast to keep the heaviest precipitation away from our area. Light snow or snow showers may continue into the evening with a total accumulation of 2 to 4 inches. Any snow that falls after sunset may also create slippery conditions on walkways and roads. Improving conditions are expected on Wednesday with more sunshine, although it will be windy and cold with a high only in the upper 30s. The average high for this time of year is in the upper 50s.
