Area Forecast Discussion
National Weather Service Charleston WV
154 PM EDT SAT JUL 23 2016
Hot and humid weather continues through the weekend. Weak
disturbance drops south today. Weak front drops through Monday
night lingering into Tuesday.
.NEAR TERM /THROUGH SUNDAY/...
Weak ripple aloft may kick off an isolated thundershower this
afternoon, but expect this to me more miss than hit. Latest
guidance keeps most of this activity just north of our CWA. If
they do develop, they should come to an end late evening, with
just some clouds lingering overnight.
Afternoon temperatures expected to top 90 degrees across much of
the lowlands today. Combined with dewpoints in the low 70s, heat
indices will climb above 100 degrees, so no changes planned to
ongoing heat advisory.
.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
Guidance suggest that a cold front will stall north of the area on
Sunday before lifting north as a warm front later Sunday night.
Then, the area will remain under a warm sector of a disturbance
crossing east across the Great Lakes Sunday night into Monday. An
approaching cold front will reach OH valley and WV. Kept likely
PoPs with this second cold front passing Monday through Monday
Humidity will stay high with dewpoints around 70 degrees. High
temperatures on Sunday should range the mid 90s lowlands to the
mid 70s higher elevations. This conditions could bring heat index
numbers into the triple digits once again Sunday afternoon.
Went closer to the super blend numbers fog temperatures through
.LONG TERM /TUESDAY THROUGH SATURDAY/...
With the front meandering thru at least the S zones Tuesday...have
kept some higher pops for the afternoon and evening hours. The
front finally gets a nudge to the S by Wednesday with mid level
drying spreading into the area keeping afternoon shra/tsra chances
confined over S WV/SW VA in the better moisture. This front
dissolves on Thursday as the next s/w trof and surface low
approach with another uptick in shra/tsra coverage during the
afternoon and lingering into Friday across the mountains.
Temps will gradually ease back closer to normal levels
midweek...likely ending the heat wave over portions of the area
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Cannot rule out an isolated thundershower this afternoon mainly
north, but not enough coverage to include in TAFs. Have some
dense river valley fog reforming tonight.
