Hazardous Weather Potential

Hazardous Weather Outlook
National Weather Service Charleston WV
725 AM EST Wed Jan 10 2018

A low pressure system will cross the area from southwest to
northeast Friday night.

The system will bring rain Friday afternoon and night. Over an inch
of rain could fall over portions of the middle Ohio Valley, central
Appalachians and Greenbrier Valley, with less than an inch over the
West Virginia lowlands. Hydroplaning is likely and poor drainage
flooding is possible, along with stream rises.

After the low crosses, the rain will change to snow overnight Friday
night or early Saturday morning. There could also be freezing rain
or sleet in the transition. The snow will then taper off to snow
showers on Saturday, and then end sometime Saturday night, last in
the mountains. Although snow accumulations will generally be light,
falling temperatures following the rain could create slick driving
conditions starting overnight Friday night or early Saturday
morning.  Any slick conditions that develop could persist Saturday,
with temperatures steady or falling.

Uncertainty as to the track and timing of the system lends lower
confidence as to the timing of temperature drop, change in
precipitation type, duration and amount of snow, and impacts on the
roads. Stay tuned for the latest updates as the week progresses.

...DISCUSSION...

A warming trend in the weather is expected for the middle and to the
end of the week. However, a strong system will impact the region
Friday into Saturday, with widespread rain possible and possibly some
heavy snow on the back side of the system.  Arctic cold air returns
this weekend, with possibly some light snow showers through the day
Saturday.
