Area Forecast Discussion National Weather Service Peachtree City GA 719 PM EDT Wed Oct 10 2018 .UPDATE... Updated for the 00Z Aviation Discussion. && .PREV DISCUSSION... /Issued 332 PM EDT Wed Oct 10 2018/ SHORT TERM /Today through Friday/... ..Remnants of Michael To Track Across East and Central Georgia... Hurricane Michael made landfall near Mexico Beach Florida as a major hurricane at category 4 earlier this afternoon. It is now making a rapid acceleration to the NE with outer rain bands already affecting Central Georgia. The most immediate concern is the tornado threat as CAPE values have increased to 2000 J/KG and helicities will remain quite high through the entirety of this tropical event. Tornado watch has been issued for all of central Georgia and extending into the southern Atlanta metro. Winds will be an increasing concern from late evening into the overnight period as the initial tight wind circulation expands allowing for a larger envelope of damaging winds. With a stronger landfall, weakening will now only take this down to a Category 1 hurricane as it approaches the forecast area. As it tracks across Central Georgia, hurricane force winds may transition to mainly gusts but effects will remain the same with hundreds if not thousands of trees and powerlines downed. Some could be without power for several days or up to a week depending on how much intensity is maintained with Michael. Have upgraded with the last package the tropical storm warning to a hurricane warning for Telfair and Wheeler counties. Remainder of warnings look on track. Did not want to confuse remainder of the area with Wind Advisory for now but did include in PNS that areas including the Atlanta metro would see some damaging winds to down trees and powerlines but no Tropical Storm force anticipated. QPF with latest run has increased slightly and will now carry 4 to 6 inches with locally higher amounts but current flood watch is unaffected. In other news, Fall makes an appearance Thursday night into Friday with lows for portions of the metro now expected in the upper 40s. Something to look forward to for those that enjoy such weather. Deese LONG TERM /Friday Night through Tuesday/... Little changes were made to the long term with the focus obviously on Hurricane Michael. Did make minor tweaks to the extended temperatures and pops to account for the latest thinking, including a slight decrease in low temperatures next week. Otherwise, the previous forecast discussion remains applicable and follows below. 31 A much quieter long term is expected with most precip ended by Thursday night with just small chances for light showers briefly over the far e central cwa. Dry and much cooler weather is then expected for Friday and Saturday with temperatures within about 5 degrees of normal. Starting Sunday and beyond, a WSW flow aloft could have limited moisture and a short wave or two in conjunction with a weak cold front forecast to move across the area on Monday. This will amount to slight chance to chance pops for light showers through this timeframe. Instability will be very limited as well. Temperatures will mostly warm to above normal but not as much as previous. BDL && .AVIATION... 00Z Update... Hurricane Michael will continue moving across central GA tonight exiting into South Carolina early Thursday. The highest winds will be in the MCN area. Rain and MVFR/IFR cigs will spread across the region this evening and continue through tonight, exiting from the west Thursday morning. MVFR/IFR cigs will become VFR toward mid day Thursday as drier air spread across the forecast area. //ATL Confidence...00Z Update... Medium on cig heights. High on remaining elements. 17 && .PRELIMINARY POINT TEMPS/POPS...

As of 1030 PM this evening, the center of Hurricane Michael was near Cordele, in Crisp County moving northeast around 20 MPH. As the storm continues to move across middle Georgia overnight, a period of damaging wind gusts of 50 to 70 mph will affect areas from Cordele to Perry to Hawkinsville to Eastman to Abbeville through around midnight. At 1015 PM, a credible weather station near the town of Arabi, in Crisp County, had a peak wind gust of 76 mph. Numerous downed trees and powerlines can be expected along with the potential for some structural damage. In addition, persistent heavy rainfall will increase the flood threat with localized flash flooding possible as a quick 1 to 3 inches of rain occurs in just a couple of hours. Residents in these areas are urged to stay inside a safe shelter for at least the next few hours as the center of still Hurricane Michael moves across middle Georgia. DJN
