Area Forecast Discussion National Weather Service Charleston SC 927 AM EDT Wed Jun 21 2023 .SYNOPSIS... Low pressure will remain stalled across the region, before lifting to the north later in the week. A cold front will approach the area early next week. && .NEAR TERM /THROUGH TONIGHT/... Another wet and busy day is ahead. Morning vapor analysis shows at least two well defined vorticity maximums poised to impact the area today; one northwest of KAME with the second near KDHN. Both these features are expected to move slowly east through the day and intact with a weak stationary front that is essentially bisecting the local forecast area. Fairly low convective temperatures, high PWATs near 2", modest instability and some low-level moisture transport will support another round of numerous to widespread showers/tstms this afternoon which will last well into the evening hours. The steering flow for individual storms is forecast to remain fairly progressive, but model hodographs look to support convective anchoring/training which could enhance the risk for locally heavy rainfall and flooding of mainly low-lying and poor drainage areas. While there is a risk for an isolated instance of flash flooding given some locations have already picked up over 4-6" in places over the past two days, the risk for flash flooding still looks too small to justify the issuance of a Flood Watch for any portion of Southeast South Carolina and Southeast Georgia at this time. In addition to heavy rainfall/flooding, an isolated severe tstm with locally damaging winds from wet microbursts can not be completely ruled out. For the mid-morning update, pops were adjusted slightly based on the latest CAMs with max values peaking at 70-90%, highest west of the I-95 corridor and mainly during the mid-afternoon to late evening hours. Highs in the lower-mid 80s look on track. && .SHORT TERM /THURSDAY THROUGH SATURDAY/... Cutoff low spinning over the region at the start of the period will begin to make northward progress through late week, before eventually transitioning to an open wave. An associated surface low will take a similar track with the nearly stationary front draped across the region to finally lift north of the area. Deep moisture characterized by PWats of 1.75-2 inches will remain in place. This pattern will support numerous to widespread showers and thunderstorms both Thursday and Friday. Localized heavy rain could result in minor flooding, and Flood Advisories could be needed. WPC highlights the area in a Slight Risk for excessive rainfall Thursday, then Marginal for Friday. The threat for organized severe weather is low, but certainly can't rule out a few stronger to perhaps severe storms each day. High temperatures will stay below normal, mainly in the lower to middle 80s, warmest on Friday. Lows will average in the upper 60s to lower 70s. The surface pattern will feature a trough of low pressure inland, with high pressure offshore on Saturday. Aloft, a mid level trough will be positioned over the eastern CONUS. There should be significantly less convective coverage than previous days, generally becoming more typical of summertime and driven by daytime heating and the sea breeze. The forecast features rain chances peaking in the 30-50% range. High temperatures will moderate closer to normal. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... Fairly quiet weather expected on Sunday with just isolated to perhaps scattered showers and thunderstorms possible during the day. A mid level trough will then amplify over the eastern U.S. Monday into Tuesday as a stronger wave passes across the Great Lakes region and into the Northeast. This will help drive a cold front towards the area, bringing some increase in rain chances. Drier conditions are expected to return on Wednesday. Temperatures through the period will be near normal. && .AVIATION /13Z WEDNESDAY THROUGH SUNDAY/... KCHS/KJZI/KSAV: A stationary front will fluctuate across the area today into tonight, while waves of low pressure ride along the front. This along with surface low pressure in Alabama and an upper level low over or near the southern Appalachians, plus diurnal heating will generate numerous to widespread SHRA/TSRA this afternoon into this evening, before coverage diminishes some overnight. The better chances for direct impacts due to the convection will be at KCHS and KSAV, where we have a TEMPO for MVFR conditions from 19-23Z. We'll show just VCSH and VCTS at KJZI for now. Adjustments to the forecast will likely be required as trends become more definite. Extended Aviation Outlook: Periodic flight restrictions in showers and thunderstorms are possible Thursday and Friday, including localized conditions IFR or lower. Shower/thunderstorm coverage will decrease over the weekend. && .MARINE... Today: A stationary front will waver inland, with waves of low pressure along the front, while the Atlantic high is found far to the south and east of the local waters. While there will be some variability to the winds across the South Carolina waters this morning, winds on these waters and all day on the Georgia waters will be S or SW at 15 or perhaps 15-20 kt. Seas will hold at 4 feet or less throughout. Tonight: Not much change in the synoptic pattern, except that the gradient pinches a bit between the inland front and the offshore high. S and SW winds will increase to 20 or 20-25 kt over the Atlantic waters, and we could require Small Craft Advisories. But since it looks marginal, we will defer to the daytime forecasters to determine whether any advisories will be required. Mariners are advised to remain weather alert today and tonight, as there will be decent coverage of showers and t-storms. Some of the stronger convection will generate gusty winds, frequent lightning strikes and heavy rains reducing visibilities to 1 NM or less. Marine Weather Statements and/or Special Marine Warnings could become necessary. Thursday through Monday: Southerly flow will prevail through much of the period. Elevated winds of 15-20 kt on Thursday could support a Small Craft Advisory across portions of the coastal waters. Winds will then settle into the 10-15 knot range late week into early next week with seas averaging 2-4 feet. Locally heavy rainfall in thunderstorms Thursday and Friday could produce gusty winds and visibilities below 1 NM at times. && .TIDES/COASTAL FLOODING... Tides continue to run exceptionally high, and due to the combination of these elevated tides, increasing south-southwest winds and potentially moderate rains, there will be a risk for shallow coastal flooding in Charleston Harbor with the high tide around 11 PM tonight. A Coastal Flood Advisory could be required for Charleston and coastal Colleton County. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. &&
