SYNOPSIS. Surface high pressure to our north and a plume of moisture to our west will continue the unsettled pattern through mid-week. Expecting near average temperatures with showers becoming more widespread each day through Tuesday. A deep upper trough will swing a cold front through the area with cooler temperatures and much drier air overtaking the area for Thursday into next weekend.
NEAR TERM /UNTIL 7 AM MONDAY MORNING/. Isolated showers expected to dissipate later this evening. Mid and upper level clouds expected to push east into the FA overnight and help keep temperatures in the low 70s. This, along with a fairly strong low level jet, expected to preclude significant fog.
SHORT TERM /7 AM MONDAY MORNING THROUGH WEDNESDAY NIGHT/. The pattern across the Southeast will begin to change Monday. Surface high pressure and associated mid/upper level ridging will begin to move east/northeast away from the region. This will increase the low level east/southeast flow through the day on Monday and into the remainder of the period. The warm moist southeast and southerly flow will increase Monday night into Tuesday. This combination will result in a good moisture gradient across the forecast area with pwat values under 1.5 inches along the NC border to just over 2 inches in the CSRA. This axis will continue to shift east/northeast Monday night into Tuesday. Values will exceed 2+ inches by late Monday night into Tuesday. Instability will be weak however with some weak divergence aloft there will be potential for a few thunderstorms mainly in the CSRA with the best moisture on Monday. Instability will once again be weak again be weak, with some weak divergence aloft, weak surface convergence . however with the moisture axis across the area and pwat values at 2 to 2.25 inches through the day there will be potential for heavy rainfall along with a few thunderstorms. The moisture axis will remain across the area into Tuesday night before moving into NC late Tuesday night. With increasing cloudiness through the period, the warmest day will be Monday with highs ranging from low 80s across the CSRA to middle 80s across the Pee Dee. With Clouds and rainfall on Tuesday, only expect temperatures to rise into the middle/upper 70s northwest Midlands to lower 80s eastern Midlands. Overnight lows will continue to be in the upper 60s to lower 70s.
WPC does mention the potential for excessive rainfall, day 3, along/east of the I-95 corridor on Tuesday, but depending on how things evolve could see this area expanded. Storm motion from late Monday night into Tuesday evening will be around 10 to 12 mph which could lead to locally heavy rainfall amounts.
LONG TERM /THURSDAY THROUGH SUNDAY/. Global ensembles remain in good agreement with the synoptic pattern through the long term with some minor intensity and timing differences. Over the past couple of runs the ensembles have developed a closed upper low over the Ohio Valley Wednesday in response to a high amplitude upper level ridge over the western Atlantic not breaking down. For Thursday and Friday the upper low will drift north/northeast with a reinforcing trough moving in Saturday/Saturday night and deepening the trough axis over the eastern US. At the surface there is excellent agreement on a cold front crossing the region Wednesday afternoon and moving offshore Wednesday night. This will allow high pressure and drier air to build in and dominate the region with cooler and drier air through the weekend. Current expected instability with the front appears weak with little divergence aloft and mid level lapse rates less than 6 C/Km so potential for strong to severe thunderstorms is low attm. With pwat values remaining around 2 inches there is potential for some heavy rain however storms will be progressing quickly across the area so any flooding potential is currently low as well. Temperatures through the long term will be below normal for highs and lows beginning on Thursday and continuing into the weekend. Temperatures will begin to moderate some by Saturday and definitely by Sunday. The area will see a touch of fall with highs in the 70s for Thursday and Friday and lows in the 50s through the period.
Model qpf forecast indicate the potential for 1.5 to 2.0 inches of rainfall across the Midlands and Central Savannah River area with the event. Some areas could see some locally higher amounts.
AVIATION /00Z MONDAY THROUGH FRIDAY/. Conditions deteriorate on Monday at all terminals .
All sites begin the TAF period with VFR conditions now that showers are moving away from CAE and CUB. MVFR conditions are being introduced to AGS/DNL early Monday morning with a low chance of patchy fog at AGS. Clouds lower and thicken tonight with low clouds reaching the Augusta area first with showers arriving around midday. Have omitted restrictions at the remaining sites but they will be introduced in future updates starting Monday afternoon.
EXTENDED AVIATION OUTLOOK . Periodic restrictions due to low clouds and precipitation are possible until a cold front moves through Wednesday night or early Thursday with drier air behind it.
CAE WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None.
