Area Forecast Discussion National Weather Service Columbia SC 203 PM EDT Thu Jun 4 2020 .SYNOPSIS... A weak upper trough will move over the region through the end of the week. Cristobal will lift north through the Gulf of Mexico over the weekend and move into the western Gulf Coast states late in the weekend while an upper ridge builds over the southeastern states early next week. && .NEAR TERM /THROUGH TONIGHT/... Weak area of low pressure moving northward near the Ga/Sc border near the coast. Satellite shows enhanced cu fields to the west side of the low near better area of low-level convergence. Regional radar does indicate a few showers forming within that area of convergence. Models do show weak to moderate instability across the forecast area this afternoon, but a capping inversion does still remain early in the afternoon. As this weakens, isolated to scattered showers/storms will develop. Models do show some weakening of the instability once the caps weakens. Pwat values are around 1.5-1.8 inches this afternoon into the evening. Would expect a few heavy showers along with isolated thunderstorms as the surface low moves northward. The low will track across the eastern Midlands overnight, and a low-level stratus deck should form near the low. Have kept mention of showers/storms in through the night, although coverage should be limited. Overnight, lows will be in the upper 60s to around 70 degrees. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... Friday and Friday night...Upper trough axis over the Ohio Valley will shift eastward into the Carolinas. This feature will interact with a surface trough in place along with PWATs approaching 2 inches to provide increased chances of showers and thunderstorms over the forecast area. Shortwave energy may also enhance any convection so cannot rule out an isolated severe storm, although think the threat is low given instability is weak to moderate and lapse rates are not that great. Heavy rain could be a threat though with such abundant moisture and relatively slow storm motion. Convection may linger into the overnight hours as the deep moisture slowly sinks southeastward through the area. Temperatures will be near normal with highs around 90 again and lows in the upper 60s to around 70. Saturday and Saturday night...The upper trough axis will be east of the area with a northwesterly flow aloft over the forecast area as Cristobal moves northward through the central Gulf of Mexico. Precipitable water values lower to around 1.5-1.6 on Saturday with little in the way of forcing for convection so will only carry low chance pops across the area with possibility of some mountain convection drifting southeastward into the area. Temperatures will again be near normal with highs in the upper 80s to lower 90s and lows in the lower 70s. && .LONG TERM /SUNDAY THROUGH THURSDAY/... Upper ridging will bridge over the forecast area Sunday, connecting the ridge over the Bahamas to the ridge over the western Ohio Valley and upper Midwest states. Cristobal is expected to impact the central Gulf Coast states by Sunday evening as a deep upper trough moves south off the Atlantic coast. There are differences among the GFS/EC with regards to the amount of moisture over the forecast area early next week as the EC pushes a backdoor cold front into the area by Sunday night while the GFS is further north and east with this boundary and therefore keeping deeper moisture over our area. By mid week the models really diverge regarding the remnants of Cristobal with the EC absorbing Cristobal with a northern stream upper trough taking it into the Great Lakes on Wednesday while the GFS is much weaker with the upper trough and does not really pick up Cristobal and instead meanders it over northern MS/AL by Wednesday. Regardless, overall moisture will deepen over the region mid week and chances of rain will increase. Given the vast differences though will make only few changes to the latter part of the extended forecast. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... Skies at all sites currently vfr with ceilings scattered clouds near 3kft this afternoon. Expect some broken ceilings to be possible near ags/dnl this afternoon, and can not rule out a brief shower at either site over the next few hours. Brief mvfr visibilities and/or ceilings will be possible with shower activity. Have mentioned a tempo group at those sites. Further north this afternoon, clouds should continue to increase near ogb/cae/cub as the low tracks northwards and into the eastern Midlands this evening. Isolated showers could also begin impacting the Midlands as the low moves through, so have begun mention of vcsh at those sites by 20z. Later on tonight, models indicating the development of a low stratus deck towards Midnight across the central Midlands sites, with conditions dropping to mvfr by that time, then possibly into ifr late tonight into Friday morning. Have trended the tafs for cae/cub/ogb that direction based on latest guidance. Further south, models not quite as strong with the indications of ifr, but due to proximity to the low, have included at least mvfr ceilings late tonight at ags/dnl. All sites should improve back to vfr by 15z Friday. EXTENDED AVIATION OUTLOOK...Periodic restrictions possible from showers and thunderstorms through Tuesday. && .CAE WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. &&
