SYNOPSIS
Atlantic high pressure will remain across the Southeast U.S.
through mid week. A cold front will move through the region late week bringing cooler conditions heading into the weekend.
NEAR TERM /THROUGH TONIGHT/
At daybreak: Satellite data and sfc based observations indicated a bank of stratus and patchy fog across portions of the inland CWA The updated forecast will feature a mention of patchy fog until 8 AM. Otherwise, the current forecast remains on track.
A shortwave ridge will remain across the forecast area this morning.
The ridge should ripple over the western Atlantic this afternoon as a broad trough approaches from the west. At the sfc, the pattern will feature high pressure from the western Atlantic to the northern Gulf of Mexico and a warm front across the Ohio River Valley. This pattern should yield south-southwest winds across the forecast area today. As temperatures peak in the upper 80s across SE GA and mid 80s across the SC Lowcountry in the mid afternoon, a weak sea breeze should develop. High resolution guidance indicates that the sea breeze will push slowly inland late this afternoon, then becoming nearly stationary 20-30 miles from the coast. Forecast soundings along and west of the sea breeze indicate that CAPE favor values around 1500 J/kg with DCAPE between 500-1000 J/kg. Shear values may increase with the arrival of the mid-level trough this afternoon, 0- 6 km shear between 25-30 kts. Scattered to numerous showers and thunderstorms are forecast to develop by late this afternoon, especially across inland portion of the SC Lowcountry. Given the forecast environment, it is possible that one or two strong to severe thunderstorms may develop late this afternoon, gusty winds the primary hazard. In addition, slow storm motions and PW values around 1.7 inches may yield some inland locations receiving localized heavy rainfall.
Tonight: Coverage of showers and thunderstorms will gradually decrease through the evening hours. However, isolated showers may linger in spots into the late night hours. Low temperatures are forecast to range between 65-70 degrees.
SHORT TERM /TUESDAY THROUGH THURSDAY/
Mid-level ridging will briefly set up over the region Tuesday into Wednesday before becoming quasi-zonal Wednesday into Thursday. The Southeast U.S. will still be positioned on the western grip of Atlantic high pressure as a series of surface lows pass across the northern CONUS. Lingering moisture from a recent passing shortwave could result in the initiation of a stray isolated shower or thunderstorm along the sea breeze Tuesday. The forecast currently features POPs ranging 10-20% considering most locations will likely stay dry. Conditions will remain dry through Thursday morning with a mix of clouds and sun. The main focus during the short-term forecast period is on temperatures, with a couple of unseasonably hot days ahead. High temps will reach the upper 80s/low 90s Tuesday, rising to the low 90s both Wednesday and Thursday, with some locations reaching the mid 90s. Locations along the beach however will be cooler, topping out in the mid 80s. Record setting high temperatures are possible both days (see Climate section below). Dew points in the upper 60s will keep heat indices from reaching the 100 degree mark. Overnight, both Tuesday and Wednesday will be mild with min temps in the upper 60s/low 70s.
LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/
A cold front will push across the area Friday bringing the next chance for showers and thunderstorms. Guidance has trended the timing of the front slightly quicker, and now shows the potential for convection to spread in as early as Thursday evening and then potentially another round Friday afternoon. In the wake of the front, high pressure will build bringing dry conditions and cooler temperatures through the weekend.
AVIATION /12Z MONDAY THROUGH FRIDAY/
12Z TAFs: VFR conditions are expected at CHS/JZI/SAV terminals through this morning. This afternoon, a mid-level disturbance is expected to arrive front the west. At the sfc, a sea breeze should develop early this afternoon, possibly drifting just a county or two inland before becoming nearly stationary. High resolution guidance indicates that thunderstorms will develop near KCHS, beginning at 19z. Convection may spread near the KSAV terminal by 23Z. The KCHS and KSAV will highlight the period of greatest thunderstorm potential with TEMPOs.
Extended Aviation Outlook: Outside of a possible stray shower Tuesday, VFR conditions are expected through the week.
MARINE
At the sfc, the pattern will feature high pressure from the western Atlantic to the northern Gulf of Mexico and a warm front across the Ohio River Valley. This pattern should yield south-southwest winds across the marine zones. Speeds are forecast to favor values between 10-15 kts today and tonight. Seas should range between 2-3 ft through the near term period. Beyond 50 nm, seas may build to 4 ft late tonight across the outer GA waters.
Tuesday through Saturday: Atlantic high pressure will maintain relatively benign conditions over the local marine waters.
Southeasterly winds in the morning will back slightly during the afternoon and evening hours each day as the sea breeze develops.
Winds will average 10-15 kt with seas 2-4 ft. Winds will increase Thursday into Friday as a cold front approaches. Small Craft Advisory conditions are possible as gusts approach 25 kt, but look marginal at this juncture. By Saturday, winds will shift out of the north around 10 kt with seas dropping to 3 ft or less.
TIDES/COASTAL FLOODING
The upcoming New Moon (May 8) and recent Perigee (May 5) will lead to high astronomical tides over the next few days. Minor coastal flooding is possible along Charleston and coastal Colleton Counties, including Downtown Charleston, during the evening high tides through Thursday.
