Area Forecast Discussion National Weather Service Birmingham AL 709 PM CDT Sun Apr 30 2017 .UPDATE... For 00Z Aviation. && .DISCUSSION... Busy day across the southeast as much of Central Mississippi was hit hard early this morning. This sent a large and rather ominous cold pool accelerating eastward across Alabama well ahead of the main frontal forcing. This cold pool will develop additional thunderstorms right along it with an occasional severe wind gust or two, but it seems that it is weakening as it progresses east. As instability is still modest in the east, will continue to hold on to a slight risk for the remaining counties that are ahead of the line. The southern end of the line has lost a little momentum, so it is possible that the threat may linger down near the I85 corridor through much of the evening and possibly into the overnight until the frontal forcing sweeps through late. Further north, the line is still translating east rather quickly and should be into Georgia over the next several hours. Any backside redevelopment along the front should not be of concern severe-wise given the decrease in instability thanks to the expansive rain shield. 17/KLAWS && .AVIATION... 00Z TAF Discussion. --Rain and thunderstorms continue tonight w/ localized impacts to visibility/ceilings; breezy, calmer and clearing through Monday-- As of 00Z/7PM, the progress of a southwest to northeast-oriented line of rain and thunderstorms has slowed atop central Alabama. There's about an even mix of plain rain and swaths of thunderstorms. The heaviest of activity in the short-term will be toward MGM-TOI on the leading edge of the complex with flight categories as low as IFR/LIFR (rain with occasional instances of nearby lightning elsewhere). Instances of breezy southerly flow will continue with gustiness as well, turning clockwise overnight to early Monday morning. An upper trough and surface cold front will remain in play through tonight. Doppler radar is showing an increase in returns back in Mississippi near the approaching cold front; thus, precipitation chances remain in the TAFs tonight into early-mid Monday morning. I've kept VFR visibilities and ceilings with this activity, but we'll monitor for necessary adjustments. As we step through the remainder of Monday, expect drying conditions and a clearing sky. Surface winds will be aligned toward the ~west-southwest, and will be on the breezy/gusty side. 89^GSatterwhite && .FIRE WEATHER... Strong gusty winds possible today ahead of an approaching cold front. Rain chances remain low through this afternoon as the cold front moves through. There are no major fire weather concerns aside from the gusty winds. RHs will remain high. && .PRELIMINARY POINT TEMPS/POPS...
