Significant snow and ice accumulations are likely across the WV mountains Tuesday night and Wednesday. Elsewhere, heavy rain could lead to flooding Tuesday night through Thursday. Read More >
.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
As of 358 AM Wednesday...
Doppler radar shows areas of precipitation lifting northeast
from central and eastern KY, northeast into southeast OH and WV.
METARs and dual pol radar indicate a precipitation transition
zone of a mix of rain and snow from Athens Ohio, southwest
across Charleston, continuing to Beckley. North of this line,
expect light snow transitioning into a mix across the prefer
warm wedge areas overnight. However, south of the line, expect
mostly liquid precipitation, in occasion mixing with ice
pellets or snow. Expect IFR conditions after 08-09Z at CRW,
HTS and BKW, spreading north to affect PKB, CKB and EKN after
09-10Z.
The precipitation transition zone could lift slowly north
overnight, and continue lifting north through Wednesday
afternoon. These conditions will bring mostly rain although
moderate at times, that could reduce visibilities to MVFR/IFR on
Wednesday. The eastern slopes of the Appalachian could
experience FZRA under trapped surface cold air tonight through
around 18Z Wednesday.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z THURSDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Timing of precipitation types and
visibility may vary overnight. Ceilings heights could vary on
Wednesday afternoon.

H = HIGH: TAF consistent with all models or all but one model.
M = MEDIUM: TAF has varying level of consistency with models.
L = LOW: TAF inconsistent with all models or all but one model.
