Area Forecast Discussion National Weather Service Columbia SC 638 AM EDT Sun Sep 19 2021
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 /THROUGH TONIGHT/. High clouds streaming over the forecast area early this morning with weak upper ridging in place. With plenty low level moisture, patchy stratus and fog will continue until shortly after sunrise.
Expect surface ridging to strengthen today with high pressure building in from the north, once again suppressing moisture to the south and west of the forecast area. The deepest moisture will remain well west associated with an upper low and SW flow aloft. Still PWATs will still be sufficient and with weak surface convergence as onshore flow develops, to force diurnally driven scattered showers and thunderstorms, mainly in the western half of the forecast area. Instability looks weaker than yesterday so once again not expecting anything to get close to severe limits. Temperatures similar to yesterday, generally warmer NE where precip chances are lower. A weak shortwave approaching from the west may help to showers lingering into early tonight but generally expect precip to dissipate before midnight.
As the upper ridge begins to weaken, tonight, expect increasing deep moisture with southerly flow shifting over our area, leading to moisture from the Gulf of Mexico. Expect increasing cloud coverage as a result, which should keep temperatures tonight around 70.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. Synoptic situation over the SE US will remain largely unchanged Monday as high pressure near New England will continue advecting Atlantic moisture into the area. At the same time a deep upper level trough over the Gulf States will push Gulf moisture northward. This combination will result in a moisture axis over the forecast area with pwat values under 1.5 inches along the NC border to just over 2 inches in the CSRA. Instability will be weak however with some divergence aloft there will be potential for a few thunderstorms mainly in the CSRA with the best moisture. The synoptic situation will slowly begin changing Tuesday as the high slides away from New England allowing the moisture axis to push into the forecast area. Instability will again be weak however with the moisture axis across the area and pwat values aoa 2 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 mostly cloudy skies limiting heating high temperatures will be in the low to mid 80s Monday and mid 70s to around 80 Tuesday with overnight lows in the mid 60s to around 70 each night.
LONG TERM /WEDNESDAY THROUGH SATURDAY/. 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 night in response to a high amplitude upper level ridge over the western Atlantic not breaking down. Through Thursday and Friday the upper low will drift northward with a reinforcing trough moving in Saturday and deepening the trough axis over the eastern US. At the surface there is excellent agreement on a cold front crossing the region Wednesday 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 near to below normal.
AVIATION /12Z SUNDAY THROUGH THURSDAY/. Patchy low stratus and fog in place this morning which as of 1030z is affecting just OGB/CAE with LIFR CIGs. Expect gradual improvement across all terminals over the next few hours as stratus does seem fairly and should dissipate shortly after sunrise. Otherwise VFR conditions are expected today with ESE winds around 5kts. Showers and storms are expected to develop this afternoon once again today yet coverage will be limited so have left any mention out of the TAF. Increasing mid and high clouds tonight should prevent widespread restrictions but deeper moisture will be moving into the region which could lead to CIG restrictions developing sometime around 12z.
EXTENDED AVIATION OUTLOOK . Chances of mainly diurnal showers and thunderstorms, along with some late night/early morning fog/stratus potential, through Wednesday. A cold front will move through Wednesday night or early Thursday with drier air behind it.
CAE WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None.
