The episode as NWS RLX wrote it up.
The last few days of July featured hot and muggy conditions alongside strong to severe thunderstorms. Only one storm proved to be severe on July 27th, passing through Gallia County in the afternoon and causing downed trees. More widespread storms took place across southeast Ohio on the 28th, with an increase in areas observing tree and power line damage as a result of the strong winds passing through. Once storms crossed the Ohio River each day, the risk for severe weather concluded.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, WV wrote its last area forecast discussion before the first event at Jul 27, 1:46 PM EST, 3 hours 9 minutes earlier.
AREA FORECAST DISCUSSION
National Weather Service Charleston WV
246 PM EDT Thu Jul 27 2023
.SYNOPSIS...
Mid-upper level ridging building toward the area through Friday
increases the heat and humidity. A front arrives this weekend
with additional showers and storms. High pressure early next week.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 244 PM Thursday...
Key Points:
* Heat Advisory remains in effect until 7 PM this evening.
* Marginal Risk for severe thunderstorms exists through tonight.
* Heat Advisory in effect Friday from 11 AM to 9 PM.
A marginal risk for severe thunderstorms continues through this
evening. Hi-res models suggest a thunderstorm complex developing
across our northern sections this afternoon, then sink south this
evening affecting the Middle Ohio Valley, northeast KY and portions
of western WV through this evening.
Some models suggest another disturbance passing overnight. This
feature could maintain at least weak convection across the area
overnight tonight. Therefore, decided to keep slight chance PoPs
during this time period. Relatively dry condition expected during
the first half Friday, but yet another upper level shortwave is
advertise moving across our north during the afternoon hours.
Therefore, increased PoPs with this feature late Friday.
Gusty southwest flow diminishes this evening, becoming light and
variable to calm later tonight. River valley fog will be possible
over areas that receive rainfall and where skies clear tonight.
Despite of possible cooling showers, very muggy conditions expected
tonight with temperatures ranging from the lower 70s lowlands, into
the lower 60s highest elevations. Hot temperatures are anticipated
on Friday ranging from the upper 90s lowlands, into the upper 70s
highest elevations. With dewpoints expected to be in the lower 70s,
Heat Index values will likely reach 100 to 105 degrees across the
lowlands, with localized higher values. Therefore, a Heat Advisory
remains in effect from 11 AM to 9 PM Friday evening.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 200 PM Thursday...
Chances of showers and thunderstorms will increase as a cold
front approaches, and then moves through the region Saturday
night or early Sunday. Models showing CAPE values of 2000-2500
Saturday afternoon with DCAPE of 700-1200. Definitely some
concern for damaging winds, and possibly large hail. In
addition, precipitable water values are in the 1.75 to 2.25
range. This could lead to some heavy rainfall in thunderstorms.
Flash flood guidance is rather high at the moment, with three
hour guidance generally in the 2.25 to 3.5 inch range.
Depending on timing of convection and cloud cover on Saturday,
may still need some additional heat advisory headlines. Will
wait until models are in better agreement before hoisting any
headlines.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
As of 1210 PM Thursday...
Models are showing a short wave moving through on Sunday, but
disagree with the timing and how much moisture will be available
behind the cold front. This leads to a range of solutions from
dry, to some showers and thunderstorms, more likely in the
south and east. Will keep chance POPs since some models show
this, but confidence is not high.
A surface high pressure system will then build over the area on
Monday and remain through mid week. The flow aloft will remain
out of the northwest. This will allow for mostly dry weather
with warm afternoons and cool nights.
Another cold front may approach from the northwest on Thursday,
but models are not in agreement with this. Will allow for a
chance of showers and thunderstorms as some models indicate.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
As of 134 PM Thursday...
The Sun's heat, ample low level moisture and a passing upper level
disturbance will contribute for the development of showers and
thunderstorms this afternoon and evening. Expect localized heavy
downpours and strong gusty winds with and nearby storms. Some storms
could become severe this afternoon and evening. Coded TSRA in TEMPO
groups at HTS, CRW and PKB as a line of convection is expected to
drop south into this evening. Coded VCTS for the rest of terminals
per uncertainty whether storms hit directly or not.
Convection should diminish in intensity and coverage later this
evening and tonight as we loose diurnal heating. However, some
models bring another upper level disturbance into the Tri-state area
(OH,KY,WV) late overnight tonight into Friday morning. These
features could maintain chances for precipitation overnight tonight.
Otherwise, IFR/LIFR conditions under dense fog could develop under
light to calm flow and over areas that clears overnight into Friday
morning.
Light southwest surface flow will gust to 15 to 20 kts this
afternoon, before becoming light south this evening, and then
light and variable to calm tonight. Stronger wind gusts can be
expected nearby thunderstorms. Moderate west to southwest flow
aloft become light west to southwest this evening.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z FRIDAY...
FORECAST CONFIDENCE: High.
ALTERNATE SCENARIOS: TAFs may need amended for direct
thunderstorm hits this afternoon and evening. Fog formation
overnight tonight may vary, with rain increasing the chance.
