AREA FORECAST DISCUSSION
National Weather Service Charleston WV
1108 AM EDT Sun May 12 2024

.SYNOPSIS...
High pressure provides dry weather into the start of the new
work week amid a warming trend. Wet weather returns Monday
night lasting into Wednesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1107 AM Sunday...

Previous forecast package looks on track. No changes needed at
this time.

As of 225 AM Sunday...

After a chilly start, any lingering patchy valley fog should
dissipate in the first few hours after sunrise, and we`ll be
well on our way to a dry, mild, and mostly sunny Mother`s Day.
Highs will be a few degrees below normal, and forecast soundings
would indicate the potential for some 15-20 mile per hour gusts
in the afternoon. Clear skies and gentle S`ly or calm winds will
allow for lows near to a few degrees below normal tonight.

&&

.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
As of 215 AM Sunday...

First half of Monday remains mostly dry under the influence of high
pressure off the coast of the Carolinas. A warm front will pass
through early leading to a warm day with temperatures above normal
for most locations; highs in the lower 80s will be common across the
lowlands.

Clouds will gradually increase from south to north during the day
though, due to the aforementioned FROPA and moisture advecting ahead
of a low pressure system over the Midwest. Precipitation chances
increase from the west in the evening with likely PoPs entering
overnight.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 230 AM Sunday...

The previously mentioned low pressure system slowly moves towards
our area across the Ohio River Valley Tuesday, producing rounds of
showers and some thunderstorms. Currently, parameters do not
support severe weather (lacking instability, weak lapse rates
and convective inhibition in place). There will likely be some
forcing along and closer to the low pressure center as it slowly
crosses the area Tuesday afternoon, this is where the greater
chances for thunderstorms will be.

Heavy rain and possible water issues still stand out as PWATs
look to be around or above 1.30" Tuesday into Wednesday. No
excessive rainfall outlooks are pending, but would not be
surprised to see a marginal risk hoisted in the next day or two
depending on the consistency of the track this low takes.

Low pressure moves off to the northeast on Wednesday as cold
front crosses. Flow will shift out of the northwest and rain
will start tapering off Wednesday evening as high pressure fills
in. Remaining mostly dry on Thursday as a result, but some
upslope showers or an isolated thunderstorm cannot be ruled out
for the mountains. A warming trend will also start on Thursday
with highs in the upper 70s to near 80 across the usual lowland
spots.

A second system, somewhat identical to the previous one, arrives
Friday. Another round of showers and thunderstorms will be
possible and instability looks to be present, as temperatures
will be warmer with much of the forecast area in a warm sector
ahead of the surface low.

&&

.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
As of 650 AM Sunday...

Fog remained limited to some remote valleys last night, so aside
from a late-breaking `sunrise surprise` at EKN, it appears we
are in the clear with respect to that. The only other thing of
note regarding aviation will be the potential for some 13-20kt
gusts from the northwest during the afternoon hours today.
