8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

SYNOPSIS. High pressure will prevail through Monday. A cold front will impact the region Tuesday, followed by another storm system for mid week. High pressure will return late week.
NEAR TERM /THROUGH TONIGHT/. As of 4 AM: IR satellite detected a cloudy corridor between the Southeast U.S. and west Texas, a gap in cloud cover existed across AL and middle TN. With broad H5 ridging across the southern CONUS, waves of high to mid clouds should stream across the forecast area through today and tonight. The center of sfc high pressure is forecast to track from E. NC this morning, pushing off the Carolina coast this afternoon and tonight. The pattern should result in light ENE this morning, winds veering from the east this afternoon, then SSE tonight. Using a blend of the warmer MOS guidance, highs are forecast to favor lower 60s, with around 60 across the Charleston Tri-County.
Tonight: H5 ridge is expected to build across the southern CONUS as a amplified trough closes off over the TX Panhandle. At the sfc, low pressure will organize over TX/OK late tonight. Near term guidance indicates that the associated warm front will lift north across the Deep South, with the deepest moisture and forcing remain along and north of I-20 across GA/SC tonight. Guidance indicates that the forecast area will remain south of the moisture, within a relatively dry environment. Based on the plain view of the guidance and MOS, PoPs will remain below SCHC tonight. Given rising llvl thicknesses through tonight, low temperatures should remain within the low 50s, with mid 50s near the GA coast.
SHORT TERM /MONDAY THROUGH WEDNESDAY/. High pressure will slide further into the Atlantic on Monday as low pressure lifts from the Central/Southern Plains into the Mississippi River Valley. As this occurs, a warm front will lift north of the area. The best forcing will exit the area as mid level ridging builds from the south, although weak isentropic ascent could support a few showers, primarily across the Charleston Tri-county. Despite a fair amount of cloud cover, increasing warm air advection will allow highs to reach the low to mid 70s. Temperatures Monday night will be quite mild as well with lows only falling to around 60. These values are close to record high minimums for Jan 26.
The aforementioned surface low will track across the Mid-Atlantic states on Tuesday, eventually dragging a weakening cold front into the region. The front will likely stall over or in the vicinity through Tuesday night. A good portion of the day could be mostly dry, then rain chances will increase, especially across interior Georgia zones, in the afternoon. PoPs remain in the 20-40% range. It will be the warmest day of the set with highs peaking around 15 degrees above normal in the mid 70s across most locations inland of the beaches.
A mid level trough will move towards the region Tuesday night into Wednesday, while a surface low develops along the stalled boundary and eventually tracks across the area. There is still a bit of discrepancy between models regarding the strength and placement of the low. However, ample forcing from upper divergence and shortwave energy will combine with PWats of around 1.5 inches to produce a solid rain event across the local area. PoPs are maximized in the 70- 80% range. Instability isn't all that impressive, but enough to maintain mention thunder in the forecast. Temperatures will be tricky given uncertain track of the low, but current forecast features highs ranging from the low 60s across northern zones to around 70 near the Altamaha.
LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/. Models are in good agreement in the long term period. A deepening low pressure system will lift away from the area on Thursday. High pressure will build in its wake and prevail into the weekend bringing drier and cooler conditions to the area.
AVIATION /09Z SUNDAY THROUGH THURSDAY/. VFR conditions expected at KCHS and KSAV through 06z Monday.
Extended Aviation Outlook: Flight restrictions possible in low clouds and showers early to mid week.
MARINE. Today and tonight: The center of sfc high pressure is forecast to track from E. NC this morning, pushing off the Carolina coast this afternoon and tonight. The pattern should result in light ENE this morning, winds veering from the east this afternoon, then SSE tonight. Speeds will favor values around 10 kts. Wave heights are forecast to range between 2-4 ft, subsiding to 1-3 ft tonight.
Monday through Friday: South to southwest winds will increase early this week ahead of an approaching cold front. Small Craft Advisories will be possible for portions of the waters Monday night into Tuesday, although it appears marginal at this time. Low pressure will impact the region Wednesday into Wednesday night, with deteriorating conditions in its wake. Small Craft Advisories will likely be needed Thursday into Friday. There is also a chance for a period of gale force wind gusts.
In addition, conditions will become favorable for sea fog development Monday into Tuesday as warm, moist air moves over the cooler shelf waters. We have maintained mention of patchy fog in the forecast and in the HWO.
