What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Birmingham, AL wrote its last area forecast discussion before this flash flood watch went out at Sep 14, 12:03 AM CDT, 4 hours 24 minutes earlier.
Area forecast discussion, Sep 14, 12:03 AM CDT, 4 hours 24 minutes before
Area Forecast Discussion National Weather Service Birmingham AL 1203 AM CDT Mon Sep 14 2020 .UPDATE... For 06Z Aviation. && .SHORT TERM... /Updated at 1154 AM CDT Sun Sep 13 2020/ Through Tonight. Central Alabama remains sandwiched in between the positively- tilted upper trough and now stalling surface front to our northwest and the increasing influence of Sally in the eastern Gulf of Mexico. As has been the case the past couple of mornings now, the low stratus clouds continue to hang on longer than anticipated. This is especially the case across the southern-most tier of counties stretching from Demopolis eastward to Montgomery and Auburn southward. Those clouds will continue to slowly mix out as we go into the late afternoon hours. The pressure gradient between Sally in the Gulf and the surface ridge off to our northeast in the Mid-Atlantic states is starting to increase with wind gusts near 20 knots observed across southern Georgia and southeast Alabama. Tropical showers are also starting to develop across Florida and southern Georgia as well, and we're expecting those to increase in coverage through the afternoon. PoPs have been increased to likely as a result across the far southeast counties based on current radar and high-res guidance trends. We'll also keep our eye on shower and storm development across our northwest counties closer to the now stalled surface front. Flood concerns continue across northern Mississippi and far northwest Alabama, but for our area in Marion County only scattered activity is anticipated at this time through this afternoon. Scattered showers and storms will continue in the forecast through the evening hours across the southern half of the area, much like what has been observed the past couple of nights. Any strong northwesterly-moving mesoscale boundary will easily lift enough parcels to keep scattered storms going between 7pm and midnight tonight. Otherwise, with tropical moisture in place we can expect most locations to only fall into the mid 70s overnight with more low clouds expected to move into the eastern and southeast counties. 56/GDG Previous short-term discussion: /Updated at 355 AM CDT Sun Sep 13 2020/ Today through Monday. Two separate features on opposite ends of the state will be the focus for rain today. An upper trof axis that resides along the MS river has been producing mostly showers across MS overnight. The trof axis will push slightly southeast today as a short wave trof tracks eastward across the Great Lakes region. This will place the far northwest counties in a favorable area for showers and a few thunderstorms today and early this evening. All eyes are on the northeast Gulf of Mexico as TC Sally tracks towards the Central Gulf Coast states. Models are in fairly good agreement in developing a northern feeder band across south Georgia and south Alabama later this afternoon, and higher pops in order for southeast portions of Central Alabama this afternoon and early evening. For a majority of Central Alabama, today will be rain free due to a intrusion of mid level dry air moving westward from Georgia. Rain chances have been reduced accordingly, to around 20 percent. The lack of rain and limited cloud cover will also allow temperatures to warm into the lower 90s for most areas. Very little rainfall expected overnight due to presence of drier mid level air. As TC Sally moves closer to the coast on Monday, several feeder bands on the north side of Sally will impact mainly south Alabama. However, the center of TC Sally will remain far enough south of Central Alabama for any significant wind or rainfall impacts at this time. 58/rose .LONG TERM... /Updated at 401 PM CDT Sun Sep 13 2020/ Slight adjustments made to the extended grids to account for changes to the forecast track of TS Sally. No significant changes to the forecast or impacts to Central Alabama were made. Rainfall continues to be the main concern, with the highest rainfall totals across west Central Alabama. Will hold off on issuing any flood watch products until tomorrow after a few more updates to the QPF forecast. 14 /Updated at 355 AM CDT Sun Sep 13 2020/ Tuesday through Saturday. Sally will continue to bear a variety of weather hazards to many locations across the Southeast & Gulf Coast Region throughout the next several days. As such, tonight's forecast update for Central AL will include at least low confidence mentioning of a few items as the system is forecast to come into close proximity to our area as early as Tuesday night. Taking the forecast picture from the National Hurricane Center and trends in latest guidance as the likely scenario, the HWO will mention these potential impacts from Sally; - Excessive Rainfall (Monday thru Friday): Storm total rainfall of 2- 5" with locally higher amounts across Central AL. Highest forecast totals are expected in southwest Central AL beginning late Tuesday and into Wednesday. Higher totals could then extend northeastward along the I-20 corridor into Thursday as the system moves into the southern Appalachians. Possible excessive rainfall could lead to localized flooding of low- lying and/or poor drainage areas. This, of course, will depend upon a variety of factors including the system's track and evolution after landfall, as well as mesoscale considerations that could exacerbate bands of convection which may lead to locally higher totals. At this time, a Flash Flood Watch has not been issued as we'll reassess forecast totals and confidence in forthcoming updates. However, heavy rainfall over a 3-4 day period (across a large spatial extent) could lead to drainage basins running bank-full, which cloud lead to river flooding. This could impact the Tombigbee and Black Warrior River basins. - Severe Weather (Wednesday thru Thursday): Given the forecast track from NHC and the latest trend in low-level kinematics in tonight's guidance, a parameter space favorable for tropical tornadoes could overspread portions Central AL as Sally pivots across the Deep South. As this depends upon other mesoscale considerations we cannot yet reasonably predict this far out (pockets of better instability, track dependent location of best low-level shear, etc), this will simply remain as a low- confidence or conditional threat in the HWO. This, too, will be reassessed in the coming days as details become more clear and confidence potentially increases. - Gusty Winds (Wednesday thru Thursday): Current forecast trajectory of Sally could lead to areas across Central AL experiencing gusty winds at times. This would particularly involve bands of showers and thunderstorms as they are able to mix better wind energy to the surface. Regardless, the system's strength, size, and track will ultimately dictate this and other threats as expected. For now, sustained winds of 15-20 mph with gusts up to 30-40 mph cannot be ruled out considering the latest NHC guidance. This could yield the eventual need for a Wind Advisory as criteria is potentially met during this time frame. Once the system transitions out of the area toward the end of the week with the help of a shortwave trough, medium range guidance suggests the passage of a surface frontal boundary and subsequent period of northerly/northeasterly wind. If this holds true, infiltration of drier/more stable air could reside across the area heading into the weekend. As a result, I show a trend of decreasing PoPs and more seasonable temperatures for Fri & Sat. 40/Sizemore && .AVIATION... 06Z TAF Discussion. Convection for the day is done. More stratus will develop/push into C AL in the early morning again with MGM/TOI having the best chances. We remain in a wet pattern with more mainly afternoon showers possible for Monday. While thunder may occur, our atmosphere is more tropical ahead of Sally, and thunder should be more isolated. Will forgo mention in extended part of TAFs for thunder. Could see some MVFR conditions with showers Monday afternoon, especially south at TOI. 08 && .FIRE WEATHER... Northeasterly to easterly surface and low-level flow is expected to continue the next few days as a surface high pressure lingers near the East Coast and Western Atlantic, as Tropical Storm Sally slowly moves west northwestward through the northern Gulf of Mexico. Surface and transport winds will favor these directions at ~5-12 mph through Monday night. Best rain chances through this evening will be across the northwest and southeast. Area-wide moisture will continue to increase as Tropical Storm Sally parallels the northern Gulf Coast, before making landfall Monday night in southeastern Louisiana. Depending on the system's track, rain chances and afternoon RH values are likely to remain quite elevated through mid next week. && .PRELIMINARY POINT TEMPS/POPS...
