Winter Weather Advisory
...FIRST WIDESPREAD WINTER EVENT OF THE SEASON...
.Precipitation is expected to overspread the area after midnight
tonight from southwest to northeast. While precipitation is likely
to start as snow areawide, it is expected to mix with and change to
sleet and freezing rain for most of the area. Locations along and
south of US-50/I-66 likely end the event as rain as temperatures
warm through the morning. Areas along the Mason-Dixon are most
likely to remain all snow through the event, but that remains
uncertain given exact low track. The Tuesday morning commute could
be impacted for all areas in the Winter Weather Advisory. Updates to
the forecast are likely, so please remain weather aware for the
first widespread winter event of the season.
* WHAT...Mixed precipitation expected, with a majority of the
precipitation expected in the form of freezing rain. Total snow
and sleet accumulations up to one inch and ice accumulations
around one tenth of an inch, with upwards of two tenths of an inch
possible on the higher ridges.
* WHERE...Portions of central, northern, northwest, and western
Virginia and eastern West Virginia.
* WHEN...From 1 AM to noon EST Tuesday.
* IMPACTS...Plan on slippery road conditions. The hazardous
conditions could impact the Tuesday morning commute.
* ADDITIONAL DETAILS...Precipitation is expected to overspread the
area after after
midnight tonight. Precipitation is expected to start briefly as snow
before mixing with and changing over to sleet and freezing rain.

Special Weather Statement
The combination of 10-hour fuel moistures around 7 to 9 percent,
relative humidities around 15 to 25 percent (except 30 to 35
percent for much of Maryland), and wind gusts around 20 to 30 mph
(locally up to 40 mph for northern/higher elevation areas) will
lead to an increased risk for the rapid spread of wildfires today.
This follows a night of poor relative humidity recoveries, despite
high temperatures only reaching into the lower 50s.
The most favorable overlap of dry fuel moisture, lowest relative
humidity, and highest wind gusts is expected over eastern West
Virginia into northern Virginia. To the south, winds will be
lighter, but humidity will be lower. To the north and west, winds
will be higher, but humidity will also be relatively higher.
Residents and visitors are urged to properly dispose of cigarette
butts, matches, and any other flammable items in appropriate
containers. Additionally, exercise caution if operating any
equipment that could create sparks and keep vehicles off of dry
grass. Most dry grasses, dead leaves, and other tree litter could
easily ignite and spread fire quickly.
Lastly, remember to obey local burn bans. For more information about
wildfire danger, burn restrictions, and wildfire prevention and
education, please visit your state forestry or environmental
protection website.

This follows a night of poor relative humidity recoveries over the
higher terrain, in spite of high temperatures only in the low 50s.

Special Weather Statement
The combination of 10 hour fuel moistures around 10 percent,
relative humidities around 25 to 30 percent, wind gusts around 20-30
mph, and high temperatures in the upper 60s to low 70s will lead to

enhance dry conditions across the area, especially in the higher
elevations.
Residents and visitors are urged to properly dispose of cigarette
butts, matches, and any other flammable items in appropriate
containers. Additionally, exercise caution if operating any
equipment that could create sparks and keep vehicles off of dry
