Area Forecast Discussion National Weather Service Charleston SC 707 AM EDT Sat Jul 4 2020

SYNOPSIS. A stationary front will linger south of the area this weekend, before lifting back north early next week. Low pressure will then bring unsettled weather to the region for much of next week.

NEAR TERM /THROUGH TONIGHT/. Today: Subtle mid and upper level troughing will exist across the area, while at the surface a stationary front remains near the Florida-Georgia border, as a weak high prevails locally. Rain chances are slim to none, with limited moisture featuring PWat only around 70-80% of normal, plus little in the way of forcing and instability. While we can't rule out a few stray showers along the afternoon sea breeze, we have no mention of convection in the forecast. Max temps will be a blend of the 1000-850 mb thickness forecast scheme, 850 mb temps and the MOS consensus. This supports highs climbing into the lower and middle 90s inland from the intra-coastal waterway.

Tonight: There is very little change in the pattern both surface and aloft, with the most notable difference from the previous 24 hours being that there is a deeper onshore flow that occurs in combination with isentropic ascent. Due to the proximity to the front to the south, there might be a few late night showers over McIntosh County where there is some low level forcing. For most places though, given the considerable dry air in place, no rainfall is expected. An east-southeast synoptic flow will generate an increase in stratus/stratocumulus late, but most likely little to no chance of fog given the dry air mass holding in place. Min temps will be very similar to what they were this morning.

SHORT TERM /SUNDAY THROUGH TUESDAY/. A stationary front will remain to the south on Sunday, although it will begin to shift back northward. Aloft, a very broad mid level low will be positioned over the Gulf Coast states. Moisture will steadily increase from the south through the day, and rain chances increase accordingly, with highest PoPs near the Altamaha. There's a good possibility that the northern zones see little to no precip coverage as the mid level dry air hangs on a bit longer. Sunday night, models are pretty consistent in showing a batch of showers moving up coastal and marine locations as the aforementioned front lifts back into the area. High temperatures on Sunday are forecast to be in the low to mid 90s, with lows Sunday night into the low to mid 70s.

Scattered to numerous showers and thunderstorms are anticipated on Monday with the front in the vicinity and PWats surging to well over 2 inches across most locations. Forcing for ascent will also be supported by shortwave energy lifting across the area in the afternoon and evening. The threat for organized severe weather appears low, however there is potential for heavy rainfall. While precip coverage won't be as high during the overnight hours, there will likely still be some activity around. Otherwise, clouds and rain will keep highs a few degrees below normal. Lows Monday night again in the low to mid 70s.

On Tuesday, a wave of low pressure could develop along the stalled front and pass over the area. Models vary on timing and location of developing this low, but regardless, abundant moisture in place and continued lift will support another wet day, perhaps the wettest of the set. PoPs were trended upward and the forecast now features rain chances around 80%. We will again need to monitor the potential for heavy rain and the associated flooding risk. Highs will be kept to the mid-upper 80s.

LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/. Low pressure is forecast to linger in the region mid to late week. There are still large discrepancies between models regarding the position and evolution of the low, however the overall pattern favors higher than normal rain chances, especially during the mid- week time frame. High temperatures will average slightly cooler than normal, while lows stay a couple degrees above normal.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Outside of any possible brief flight restrictions in light fog and/or stratus/stratocumulus late tonight, solid VFR will dominate at KCHS and KSAV.

Extended Aviation Outlook: Flight restrictions are likely at times early to mid week due to showers/thunderstorms.

MARINE. Today and tonight: Not much happening over the coastal waters, with weak high pressure holding in place, keeping a stationary front to the S. Even with sea breeze influences this afternoon, winds will be no higher than around 10 kt, while seas hold at or below 2 ft.

Sunday through Thursday: A stalled front south of the area on Sunday will lift back north on Monday. Low pressure will then impact the region through Thursday. Winds and seas will ultimately be dependent on the position of the low, so forecast confidence towards the middle of the week lowers considerably. At this point, conditions are forecast to stay below Small Craft Advisory criteria.

TIDES/COASTAL FLOODING. It's a sure bet for at least shallow coastal flooding with the high tide around 830-900 pm this evening across parts of the lower South Carolina coast, most especially in and near Charleston. A Coastal Flood Advisory will be required later today.

Astronomical influences will maintain higher than normal tide levels into early next week. Minor coastal flooding will be possible around the time of the evening high tides, primarily along the South Carolina coast. In addition, the risk for heavy rain early next week will only add to any tidal flooding.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
