Area Forecast Discussion National Weather Service Birmingham AL 1205 AM CDT Sun Sep 1 2019 .UPDATE... For 06Z Aviation. && .SHORT TERM... /Updated at 0310 PM CDT Sat Aug 31 2019/ Rest of Afternoon through Sunday. At 20:10Z/3:10 PM, a trough axis was observed moving westward through the Gulf of Mexico, with powerful Category Four (Major) Hurricane Dorian approaching the northwestern Bahamas. A surface high was centered toward our north. In turn, large-scale, low- level flow is from an easterly direction across our region, as observed on regional 18Z soundings. This flow is tapping into a bit of higher PWAT content over southern Georgia, supporting a chance of isolated to scattered showers & storms near and southeast of the Interstate 85 corridor afternoon into evening. Moody AFB, GA RADAR shows an arching complex of rain & storms moving westward via outflow propagation. This activity could affect our southeast counties heading into the evening time frame, if it holds together. Through Sunday, Major Hurricane Dorian will begin its decline in forward speed as it gets closer to making its (forecast) northward turn just offshore of the Southeast U.S. coastline. For Central Alabama, forecast guidance continues to show a northwest to southeast gradient in PWAT values, highest across the southeast. We'll be void of any upper-level features as we sit between ridges to the west/east & troughing toward the north. However, given an influx in moisture + daytime heating, we should see a round of isolated to scattered showers & storms, mainly southeast of Interstate 59 where chances have been raised in areas. 89^GSatterwhite .LONG TERM... /Updated at 310 PM CDT Sat Aug 31 2019/ Not many changes regarding the extended time frame. The latest NHC forecast concerning Dorian has the system turning northward along the east coast. This will increase the northerly flow aloft and put a northeast to east surface wind over Central Alabama. Therefore, our atmosphere overhead should remain quite dry. Therefore, no rain chances are mentioned Monday through Saturday at this time. Lows temperatures will bounce around from slightly above to slightly below normal generally stay above normal for early September. 75 Previous long term discussion: /Updated at 0317 AM CDT Sat Aug 31 2019/ Monday through Saturday. As we go into Monday, the main upper level trough axis has shifted to our east, and the ridging has started to build in across the area. This will shift our winds more northeasterly, and we'll once again see a noticeable drop in moisture across the southeastern counties. Therefore, I have lowered rain chances Monday through Tuesday across Central AL. Hurricane Dorian is forecast to be just off the eastern coastline of Florida by Tuesday evening before turning to a more northerly track through the end of the week. The exact track of Dorian will continue to play a big role in our weather for Central AL Wednesday through Saturday. Based on the current track forecast, most of the tropical moisture and outer convergent bands from Dorian look to remain just east of our area as the system moves northward. Therefore, I've trended PoPs downward for all of our area and won't include any mentionable rain or storms chances. This may still change if Dorian makes any slight westward trend than currently expected, so the forecast for Wednesday through Saturday remains uncertain. 25/Owen && .AVIATION... 06Z TAF Discussion. Convection is finally done for the night at the terminals. Across the I-85 and south corridor (MGM/TOI), sufficient low level moisture will be around during the late night and early morning hours for low stratus for MVFR and some IFR cigs. More scattered afternoon convection is possible for MGM/TOI again on Sunday. The rest of the TAFs are expected to be VFR for the next 24 hours with drier air across the north. 08 && .FIRE WEATHER... A dry airmass remains over Central Alabama. Minimum relative humidity values will be in the 30s again this afternoon. Light winds aloft are keeping conditions above critical thresholds. Moisture will increase today across the south with rain and thunderstorm chances increasing as well. Isolated to scattered rain chances are expected across most of our forecast area on Sunday. && .PRELIMINARY POINT TEMPS/POPS...
