Area forecast discussion, Apr 23, 11:05 AM EDT, 1 hour 40 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 1105 AM EDT Thu Apr 23 2020 .UPDATE... Updated to add the TOR watch for the far southern CWA. Intensifying line of thunderstorms will continue eastward for the next hour or so. Potential for additional strong/severe thunderstorms still exists for later this afternoon/evening. && .PREV DISCUSSION... /Issued 1034 AM EDT Thu Apr 23 2020/ SHORT TERM /Today through Friday/... Difficult forecast for today. Large shield of stratiform rain with a few thunderstorms continues to push off to the SE. Pretty big dilemma with the forecast today with two main questions: Will the CWA recover enough for late afternoon/evening thunderstorms? If so, what is the potential for severe weather? Warm front pretty well depicted across the panhandle of Florida. Dewpoints along the coast are in the 60s, with lower 70s just offshore. Back across MS/LA, dewpoints have begun to surge into the 70s. Do think the warm front/warm sector will surge northward today, but not confident on exactly how far north the boundary will make it. BL winds have backed off a bit across northern GA in the 12z models...inferring that the boundary may not make it much north of I-20. This makes sense as the airmass north of I-20 has been fairly well stabilized with the morning convection and the wedge intensified. What is not being handled well in the short term models is the convection currently developing across the northern Gulf, surging NE. If this activity continues to surge NE and the atmosphere across portions of central and southern GA recovers, late afternoon/evening thunderstorms will be likely - with the potential for severe weather. However, coverage of strong/severe storms will be less than earlier expected.The main hazards would be damaging wind gusts and a few tornadoes. If the activity across the northern Gulf ends up hugging the coast, the CWA would likely be cut off from any widespread thunderstorm/severe weather threat. NListemaa PREV DISCUSSION... /Issued 747 AM EDT Thu Apr 23 2020/ PREV DISCUSSION... /Issued 434 AM EDT Thu Apr 23 2020/ SHORT TERM /Today through Friday/... Current radar loop shows rain over our area now with the developing frontal system sweeping across MS/LA. There are still some differences in model solutions with intensity and location but they all show this system sweeping through North and Central GA today. For the most part we should continue to see rain across the area through daybreak with the main frontal boundary approaching NW GA by 12z. This system looks like it is weakening a bit especially along its northern half and should continue to do so as it nears the state. The models do show some strengthening of this system during daytime heating while this system is directly over central GA. A brief lull in convection is likely during the late morning/early afternoon before firing during the mid-late part of the afternoon. The warm front is currently over southern AL and is moving slowly northward. This front should stall across Central portions of GA this afternoon. Conditions will become favorable for discrete convection that may eventually morph into another strong line/QLCS during the afternoon and evening hours. The afternoon convection will also have 60+ dewpoints to work with, which will contribute to CAPE values 1500-2000 J/kg range. This will also be determined by just how far north the warm front moves today. The mid and upper levels will also be favorable with a 60-80kt 850 jet, strong shortwave energy and broad/strong upper divergence. Forecast hodographs still show good potential for tornadoes along with damaging wind gusts. With all this being said SPCs enhanced risk area still looks good and it appears the best chances for severe storms will be after 2pm across mainly central and portions of N GA. This frontal system is expected to weaken a bit after sunset as it moves south of the area by 2am Fri. A drier airmass moves in behind this system and Friday looks to be dry with high temps in the 70s and 80s. 01 LONG TERM /Friday Night through Wednesday/... Models tend to agree that this weekend will include a slight chance for scattered showers and thunderstorms as a weak trough moves through the Ohio river valley but widespread storms are not expected given the weak moisture return and some dry air entrainment. The best chance for rain will be Saturday when rainfall totals across northern Georgia are expected to be around a quarter of an inch. Temperatures take a dive Sunday into Monday as a cold front sweeps through. Subsequent NW flow will limit temperatures to the mid 60's across the north and low 70s in the south, but should rebound to more seasonal conditions by Tuesday as the flow becomes more westerly and moisture returns out ahead of another shortwave that looks to move across the lower great lakes. A cold front with this system will be the next round of showers and storms on Wednesday. Vaughn AVIATION... 12Z Update... Light to moderate showers and isolated thunderstorms are moving across the area this morning. Expecting precip to continue through tonight with thunderstorms increasing this afternoon into the evening hours. Ceilings are mainly in the VFR range but will see some MVFR and brief periods of IFR ceilings in and around the afternoon convection. Winds are mainly out of the E to SE and will slowly turn to the SW through this afternoon. Once the front moves through they will turn to the west Wind speeds will stay in the 5-10kt range today with some gust to 20kt in and around any stronger storms this afternoon. //ATL Confidence...12Z Update...
