In Carroll, 5 inches of snow was measured in Manchester, and 4.3 inches near Westminster. Close to 3 inches was on the ground in Parkton in northern Baltimore County, while earlier totals of an inch or two in Howard County remained unchanged.
8:42 a.m.: Heavier bands of snow were moving through the Washington, D.C., area as the storm intensified. Rain over the I-95 corridor was expected to change into snow in the morning hours, with snow accumulation totals cut slightly for areas closest to the Chesapeake Bay.
The National Weather Service was still forecasting 8-10 inches for areas north and west of I-95, with 4-6 inches forecast to the east and south, including Anne Arundel, southeastern Baltimore and Harford counties.
Local meteorologist "Eric the Red" said that although the storm has yet to intensify and show its heaviest snowfalls, expectations of accumulations may need to be cut to 1-3 inches east of I-95, 2-6 inches in Baltimore and the surrounding suburbs and 4-8 inches further north and west.
7:58 a.m.: Winds have already been gusting heavily, but power outages are minimal so far with only light snow coating trees so far.
Gusts of 25-30 mph have been recorded every hour since 4 a.m. at BWI Marshall Airport, according to the National Weather Service.
Baltimore Gas and Electric Co. was reporting 131 customers without power as of 7:45 a.m.
At BWI, airlines are still operating flights though there were a number of canceled flights with impacts from the storm being felt across the Midwest and East. There were no unusual lines at the airport Wednesday morning, and many airlines relaxed ticket change policies, said BWI spokesman Jonathan Dean.
“To this point in the early morning hours conditions at BWI are mostly just wet," Dean said. “The airport’s snow removal team has been planning and preparing for several days. The airport employees have been here all night and are prepared to clear runways and taxiways as needed.”
7:22 a.m.: Light snow had already fallen by daybreak across many areas west of I-95. In Westminster, 2 inches had fallen, with 2.5 reported in Eldersburg, 1.6 inches in Columbia and 3.5 inches in Frederick. Lighter totals were reported to the east, with half an inch in Middle River.
The prospect of more snow had many offices and governments around the region closed. That included the federal government. State government employees were granted liberal leave, along with employees of Baltimore City and Baltimore, Harford and Howard counties. Offices were closed in Carroll County.
Government offices in Anne Arundel County are open and functioning regularly Wednesday -- making them the exception in the region. Annapolis government offices were meanwhile delayed 2 hours opening with a liberal leave policy, and the Maryland General Assembly's schedule was unchanged.
6:00 a.m.: Snow was expected to begin early Wednesday morning, possibly starting as rain or a wintry mix. Forecasts as of late Tuesday were calling for 6-12 inches of accumulation across the region, with the highest totals to the northwest of Interstate 95, according to the National Weather Service.
Blustery winds were meanwhile expected, with breezes of 15-25 mph and gusts of 35 mph or greater. The weather service cautioned that could mean poor visibility with blowing snow, and combined with snow-covered roads could make for treacherous travel.
A winter storm warning was in effect for all of Central Maryland through 3 a.m. Thursday. While earlier forecasts had called for lighter accumulations south and east of I-95, forecasts as of late Tuesday included Baltimore and points west and south in an area that could see 8-10 inches.
The snow was forecast to be wet and heavy, causing concerns of power outages from downed trees and tree limbs. Baltimore Gas and Electric Co. officials said they were preparing for the possibility of hundreds of thousands of power outages.
The forecast spurred a flurry of activity Tuesday among everyone from first responders to utilities to school districts. For more details on storm preparations, read this morning's print edition story.
