AREAS AFFECTED…PARTS OF NWRN NC THRU CNTRL VA

CONCERNING…HEAVY SNOW

VALID 011816Z – 012115Z

AN INITIAL BAND OF HEAVY SNOW IS EXPECTED TO GRADUALLY DEVELOP BETWEEN NOW AND 20-21Z…THEN LINGER INTO EARLY EVENING…WITH SNOW RATES IN EXCESS OF 1 INCH PER HOUR POSSIBLE.

THE SOUTHEASTERN STATES DEEP CLOSED LOW IS NOW BEGINNING TO LIFT NORTHEASTWARD TO THE LEE OF THE SOUTHERN APPALACHIANS. AS THIS PROCESS CONTINUES THIS AFTERNOON…TO THE SOUTHEAST OF THE DIGGING UPPER TROUGH ACROSS THE GREAT LAKES REGION…MODELS INDICATE THAT LOWER/MID TROPOSPHERIC FRONTOGENESIS WILL STRENGTHENING BENEATH INCREASINGLY DIVERGENT UPPER FLOW…FROM THE LEE OF THE CENTRAL APPALACHIANS THROUGH THE MID ATLANTIC SEABOARD. THIS IS EXPECTED TO CONTRIBUTE TO STRENGTHENING DEEP LAYER UPWARD VERTICAL MOTION…INCLUDING THROUGH THE FAVORABLE MIXED PHASE REGION FOR LARGE DENDRITIC ICE CRYSTAL GROWTH.

SOME UNCERTAINTIES EXIST CONCERNING THE CONTINUING PRESENCE OF SOMEWHAT MARGINAL LOW-LEVEL TEMPERATURES FOR SNOW REACHING THE SURFACE. BUT…GUIDANCE…INCLUDING THE SREF…STILL INDICATE THAT…IF THERMODYNAMIC PROFILES ARE NOT ALREADY SUPPORTIVE… ENOUGH COOLING WILL PROBABLY OCCUR DURING THE ONSET OF PRECIPITATION TO SUPPORT SNOW…OR A QUICK CHANGEOVER TO SNOW…FROM THE NORTHWESTERN NORTH CAROLINA PIEDMONT THROUGH CENTRAL VIRGINIA. THIS APPEARS MOST LIKELY NEAR OR NORTHWEST OF A DANVILLE/RICHMOND LINE BY THE 21-23Z TIME FRAME…INCLUDING LYNCHBURG…PERHAPS ROANOKE AND CHARLOTTESVILLE…BUT STILL SOUTH OF THE WASHINGTON D.C. AREA.

IN GENERAL…MODEL FORECAST SOUNDINGS INDICATE STEEPENING MID-LEVEL LAPSE RATES THROUGH THE AFTERNOON…ATOP AN INCREASINGLY DEEP ISOTHERMAL LAYER NEAR OR JUST BELOW FREEZING. THIS WILL BE VERY FAVORABLE FOR HEAVY WET SNOW…AND MID-LEVEL DESTABILIZATION MAY BECOME SUFFICIENT FOR STRONGER CONVECTIVE BURSTS…PERHAPS ACCOMPANIED BY ISOLATED LIGHTNING.

… Winter Storm Warning remains in effect until 2 PM EST Monday…

A Winter Storm Warning remains in effect until 2 PM EST Monday.

Low pressure over South Carolina will move up the eastern Seaboard this evening… creating a tight gradient of accumulating snowfall over the mid Atlantic region. Accumulating snows have begun to affect portions areas of north central Virginia and southern Maryland. Snowfall will be heaviest with this storm between 8 PM and 3 am. Snowfall may taper off for a period afterwards… before another period of snow occurs during the morning hours. Precipitation is expected to end by mid morning Monday.

For areas from the Blue Ridge to Interstate 95 5 to 7 inches of snow can be expected by Monday morning. Between I-95 and the Chesapeake Bay totals of 7 to 10 inches are expected.

Gusty winds will develop after midnight and last throughout the day Monday.

A Winter Storm Warning means significant amounts of snow are expected or occurring. Strong winds are also possible. This will make travel very hazardous or impossible. —– COMMENT: AUTHOR: A Yahoo! user DATE: 03/01/2009 20:36:37 Winter Storm Warning

Statement as of 10:13 PM EST on March 01, 2009

… Winter Storm Warning remains in effect until 2 PM EST Monday…

Low pressure off the South Carolina coast will deepen as it moves up the mid Atlantic coast overnight into Monday morning. This low pressure system will bring snow to the mid Atlantic region.

One area of snow will move across much of Maryland… northern Virginia and the District of Columbia late this evening and during the wee hours of the Monday morning. A second area of snow associated with the low pressure system will move across the warning area during the morning rush hour.

The highest total snow accumulations are expected to run along and to the east of Interstate 95. Total accumulations are expected to range from 6 to 9 inches in this area… with the higher end of the range most likely occurring across central and southern Maryland and into Virginia near the Fredericksburg area.

To the west of Interstate 95… a tighter gradient of snowfall accumulation will occur. A range of 3 to 6 inches of snow is expected west of Interstate 95… with locations near the Blue Ridge favoring the lower end of the snowfall range.

Gusty winds will also develop overnight into Monday. Wind gusts up to 35 mph will lead to blowing snow.

A Winter Storm Warning means significant amounts of snow are expected or occurring. Strong winds are also possible. This will make travel very hazardous or impossible.
