.SYNOPSIS...
Upper level disturbance brings chances for showers overnight,
and Saturday. Drier Saturday night through Sunday night as a
upper ridge takes control. Tropical system approaches by mid
week.
&&
.NEAR TERM /THROUGH TODAY/...
As of 205 AM Saturday...
Ample and persistent upper level trough, with axis along the
southern states, will gradually advance east through Saturday night.
This shortwave will pull moisture across the eastern mountains,
allowing an increased chance for showers and perhaps a few
isolated storms.
Welcomed rainfall accumulations from 0.50 to 0.75 inches are
expected across most of WV, with higher amounts in and near the
mountains. Repetitive showers and storms, or slow moving storms
could result in isolated water issues through tonight. WPC keeps
a Marginal Risk for excessive rainfall over the eastern half of
WV, including SW VA through tonight.
Cloud cover and a gentle northerly breeze will keep afternoon
temperatures from the low 80s across the lowlands, ranging into the
upper 50s northeast mountains. High humidity will keep lows in the
upper 50s to lower 60s tonight.
&&
.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
As of 205 AM Saturday...
By Saturday night, the upper trough moves overhead, providing
forcing along and east of the mountains. This will bring drier
conditions to the end of the weekend and start of the new work week
as the aforementioned upper disturbance shifts east of the
Appalachians losing its influence over the local area. However,
isolated showers or storms can not be ruled out along the mountains
Saturday night into Sunday night.
Drier conditions will continue Monday and Monday night as an upper
ridge from the northwest takes control over the OH valley and
most parts of WV.
High temperatures Sunday/Monday will be slightly above normal with
low to mid 80s across the lowlands, ranging into the mid 60s northeast
mountains. Clear skies and near calm flow will allow for strong
radiational cooling and associated dense river valley fog
development Sunday night into Monday morning. Monday night
looks warmer, in the lower 60s due to abundant cloud cover
expected.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 205 AM Saturday...
We are closely watching a strengthening tropical system that is
expected near the Southeast coast by Tuesday. This system is the key
to our weather forecast for next week, but its exact track is still
very uncertain. There are two potential outcomes. If the system
stays out at sea, a surface high pressure will keep our weather dry.
However, if the system moves inland across the Carolinas, this
will bring a chance of showers and possible heavy rain to our
area, especially later Tuesday and on Wednesday.
Because we`re still a few days out, the forecast calls for a 20 to
40 percent chance of rain Tuesday and Wednesday. If the system gets
closer, probability of precipitation will increase. By Thursday,
conditions should dry out as high pressure takes over. Expect
temperatures to be near or slightly warmer than normal for this
time of year.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
As of 130 AM Saturday...
Radar imagery shows a large area of showers with embedded
thunderstorms east of the mountains at the time of writing. This
activity is associated with a mid level shortwave lifting north
along the mountains overnight. Expect showers to move into BKW
and EKN overnight into Saturday. Low stratus may develop along
the eastern mountains as well. On the other hand, terminals
across the far west (HTS, CRW and PKB) could experience patchy
dense fog under mostly clear skies overnight into Saturday
morning. Clouds may move further west, suppressing fog formation
at CRW later overnight. Otherwise, MVFR/VFR conditions will
prevail.
Showers become more widespread on Saturday, though precipitation
chances remain highest for the eastern terminals and then lessen to
the west. Although conditions will gradually improve during the day,
some MVFR may persist along the mountains for the bulk of the TAF
period.
North to northeast winds will be calm to light overnight, then
light and variable through Saturday.
