Area Forecast Discussion National Weather Service Charleston SC 1130 PM EDT Mon Aug 3 2020

SYNOPSIS. Isaias will move north into the upper South Carolina or lower North Carolina coast late tonight. A stationary front will stall out across the Southeast U.S mid to late week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. As of 1120 PM: Latest update from NHC indicates that Isaias has made landfall near Ocean Isle Beach at 1110 PM. Conditions will improve across the region tonight. Tropical Storm Warnings for Charleston and Berkeley Counties, Flash Flood Watch, High Surf Advisory have been cancelled with this update.

Previous Discussion: This evening: The circulation of now Hurricane Isaias is almost out of the coastal waters and the last bit of rain associated with it is only impacting far eastern Berkeley and Charleston counties. We have maintained the Flash Flood Watch since rain is still occurring, but the threat is certainly quickly diminishing. As if a tropical system wasn't enough, we now must turn our attention to the west where a line of thunderstorms has entered the forecast area. It certainly doesn't appear to be severe, but cloud to ground lightning, brief heavy rainfall, and gusty winds will be possible for much of southeast Georgia and even just across the Savannah River into southeast South Carolina. This convection should dissipate by late evening and the rest of the overnight is rain free.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. There will be a return to a more normal convective pattern by mid-week in the wake of Isaias as a broad, longwave trough persists across the eastern United States. Scattered convection appears likely each afternoon mainly along/inland of the sea breeze. Some isolated, nocturnal convection will be possible across the coastal waters, especially out closer to the western wall of the Gulf Stream. Temperatures will be near seasonal normals with highs ranging form the lower-mid 90s each afternoon with lows in the lower- mid 70s, except upper 70s/near 80 at the beaches and Downtown Charleston.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. A mid-level trough will persist over the East Coast while a stationary front hovers over or near area. The typical afternoon and evening showers and thunderstorms are expected. Temperatures should be near normal.

AVIATION /03Z TUESDAY THROUGH SATURDAY/. At KCHS: Rain associated with Isaias has moved out and skies will steadily clear. MVFR ceilings will linger for a bit, but VFR conditions should return by at least the early morning hours. Thereafter, VFR will prevail.

At KSAV: Overall, VFR conditions are expected to prevail. We will have to watch a line of thunderstorms moving through southeast Georgia. If the storms were to reach the terminal it would be by around 01 to 0130 UTC.

Extended Aviation Outlook: There is a risk for scattered showers/tstms impacting the terminals day afternoon.

MARINE. Tonight: Isaias has almost moved out of the local waters. We have now dropped the Tropical Storm Warning for the Charleston Harbor and replaced with a Small Craft Advisory. The same should happen for the Charleston County waters with the next advisory. Conditions will then continue to improve through the rest of the night.

Tuesday through Saturday: There are no concerns. Some backswell from Isaias will impact the waters Tuesday, but will quickly diminish. Otherwise, a typical summertime mid-summer marine pattern will prevail with southerly winds and localized sea breeze enhancements each afternoon. Seas will average 2-4 ft with seas around 10 kt.

Rip Currents: The High Risk continues through tonight for all beaches. Lingering backswell generated by Isaias will support a moderate risk for rip currents at all beaches Tuesday.

CHS WATCHES/WARNINGS/ADVISORIES. GA . High Risk for Rip Currents until 6 AM EDT Tuesday for GAZ117-119- 139-141. SC . High Risk for Rip Currents until 6 AM EDT Tuesday for SCZ048>051. MARINE . Small Craft Advisory until 2 AM EDT Tuesday for AMZ330-352-354. Tropical Storm Warning for AMZ350. Small Craft Advisory until 8 AM EDT Tuesday for AMZ374.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
