Area Forecast Discussion National Weather Service Charleston SC 315 PM EDT Mon Jun 24 2024

SYNOPSIS
High pressure will remain over the western Atlantic while a weak cold front approaches the area. This front will likely linger near the area through mid-week.

NEAR TERM /THROUGH TONIGHT/
Convection has been very slow to develop today. The last few runs of the WoFS since the initial 24/17z run have been trending drier with each run. Pops through the remainder of the afternoon have been lowered to 20-30% as a result. Dewpoints are finally showing signs of mixing out inland, but are holding well into the 70s across the coastal corridor. Heat indices have been as high as 108-113 based on the more reliable observation sites (with RAP dewpoint confirmation), mainly just inland from the coast where dewpoints are running in the mid-upper 70s. The current Heat Advisory through 6 PM looks on track. Heat indices may surge a bit farther inland as the sea breeze moves inland, but any 108+ values should hold in the current advisory area.
There may also be an isolated 113+, but any such instances look to remain fairly isolated and not enough for an upgrade to an Excessive Heat Warning.

Later this evening, the tail end of convection moving across the Pee Dee could interact with the inland moving sea breeze to spark off additional showers/tstms. There is a modest signal showing this cluster impacting areas roughly along/north of the I-26 corridor. Pops as high as 40-50% were highlighted in this area with 20-30% elsewhere. An isolated strong/severe tstm could occur with elevated DCAPE in place. Once convection moves offshore and/or dissipates, expect a warm/humid night with lows from the lower-mid 70s well inland to the lower 80s at the beaches and Downtown Charleston.

SHORT TERM /TUESDAY THROUGH THURSDAY/
Broad troughing will persist across the East Coast on Tuesday, gradually shifting to zonal flow on Wednesday and a return to broad troughing Thursday. At the surface a weak cold front will likely linger in the vicinity of the forecast area through midweek. 850 hPa temperature anomalies will remain rather warm through the period, which combined with little mixing each day, will yield hot and humid conditions. Heat index values are forecast to reach 102-107F inland. A few spots may make a run at 108F along the coastal counties, however coverage of these values is not enough to warrant Heat Advisories at this juncture. Each afternoon isolated to scattered showers and thunderstorms will be possible, as PWATs remain elevated with the front in the vicinity. PWAT values are forecast to remain near 1.6-1.8", which is slightly above normal for this time of year. CAPE values are forecast to reach around 1500 J/kg, with model soundings indicating >1000 J/kg of DCAPE. A strong to marginally severe thunderstorm cannot be ruled out any afternoon, with strong wind gusts as the main hazard.

LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/
An anticyclone aloft will be positioned over the southern U.S.
and will slowly shift eastward over the southeastern states through the weekend. At the surface high pressure will extend into the forecast area from the east with the center of high pressure centered over Bermuda. Hot and humid conditions will likely persist into the weekend. Head index values are forecast to reach from around 103- 105F inland with values approaching 108F along the coastline. Head Advisories may be required. A summertime pattern is expected through the period, with the highest precipitation chances in the afternoon hours.

AVIATION /18Z MONDAY THROUGH SATURDAY/
24/18z TAF Discussion: KCHS/KJZI/KSAV: Best chances for tstm impacts this afternoon will be at KSAV and possibly a far north as KJZI. VCTS will be highlighted at both terminals from roughly 19-21z with a TEMPO for MVFR conditions in TSRA at the same time at KSAV. Risk for showers/tstms could increase at KCHS by mid-evening as some interaction with an approaching surface trough and inland moving sea breeze occurs. VCSH was highlighted 02-05z for now to trend. Otherwise, VFR through the period.

Extended Aviation Outlook: Brief flight restrictions will be possible at all terminals with afternoon showers and thunderstorms.

MARINE
Tonight: South to southwest winds 15-20 kt will dominate the waters tonight. There may be a few gusts to 25 kt, but durations do not look long enough to support a Small Craft Advisory at this time. Seas will average 3-5 ft.

Tuesday through Friday: Generally tranquil marine conditions are expected through the period. Winds will gradually back each day and veer overnight, strongest along the coastline as the afternoon sea breeze/overnight land breeze develops. Seas should average 2 to 3 ft.

CLIMATE
The low temperature at KCHS so far today is 80. If this holds, this will break the previous record high minimum of 79 set back 2016.

CHS WATCHES/WARNINGS/ADVISORIES
GA...Heat Advisory until 6 PM EDT this evening for GAZ117-119-139- 141.
SC...Heat Advisory until 6 PM EDT this evening for SCZ048>051.
MARINE...None.
