AREA FORECAST DISCUSSION
National Weather Service Charleston WV
123 PM EDT Fri Mar 15 2024
.SYNOPSIS...
-- Changed Discussion --
Showers and drizzle continue along and ahead of a cold front
through early this evening. Cooler and dry this weekend. Cold
to start the new work week, with snow showers.-- End Changed Discussion --

.NEAR TERM /THROUGH SATURDAY/...
-- Changed Discussion --
As of 120 PM Friday...
A surface cold front continues to slowly work its way through the
region from northwest to southeast through this evening. Ahead and
along the cold front, patchy showers and perhaps an isolated rumble
of thunder will be possible through the afternoon. Some patchy
drizzle may briefly linger behind the cold front, but would not
expect any additional measurable amounts.
Could see some clearing toward dawn across southeast Ohio, which
given light winds and recent rainfall could yield some fog heading
into the morning Saturday and will code some up for these areas. Any
fog or remnant low clouds should mix out into substantially drier
air aloft by late morning with temperatures rising to near normal
values for this time of year by the afternoon.-- End Changed Discussion --

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 230 AM Friday...
To start this period off on Saturday, we have upper level zonal
flow and surface high pressure which will hold the area at bay
from unsettled weather. Temperatures will be trending downward
from what the area has been enduring which will be right above
seasonable.
For Sunday, a low pressure system to the north will traverse across
the region eastward promoting some slight chance POPs of rain
for the northern periphery of the CWA. The features frontal
boundary will hang just down into our area, which should be
fairly dry, but will still have potential to see a shower or two
in that region. This will reinforce cooler temperatures
dropping them down to right around seasonable, maybe even a few
degrees below for Sunday.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 1215 PM Friday...
A cool northwesterly flow remains across the area on Tuesday, with
the potential for another fast moving clipper type system affecting
the area Tuesday night into Wednesday, with additional light snow,
mainly across the northern mountains. Temperatures moderate towards
the end of the period as heights build and southerly flow increases
out ahead of another system, which looks to affect the area late in
the week into the weekend.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
As of 120 PM Friday...
Showers and light drizzle continue ahead of and along an approaching
cold front with deteriorating flight conditions ahead of and along
the front. Behind the front, improvement to MVFR ceilings is expect
late this afternoon and into this evening, with eventual clearing
across at least portions of SE OH and NW WV heading into daybreak
Saturday. With light winds and recent rainfall, this will likely
yield at least patchy fog, most likely to affect PKB and HTS, but
could easily extent to the other terminals. At BKW, upslope flow
likely yields persistent LIFR conditions shortly after winds switch
around to the northwest.
Winds westerly 8-10KTs, shifting west-northwest after frontal
passage, and turning light overnight.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY...
