08What forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before this river flood warning went out at May 25, 6:42 AM CDT, 2 hours 28 minutes earlier.
Area forecast discussion, May 25, 6:42 AM CDT, 2 hours 28 minutes before
Area Forecast Discussion National Weather Service Shreveport LA 642 AM CDT Tue May 25 2021 .AVIATION... For the 25/12z TAFs, convection is moving northeast through Southeast Oklahoma and Southwest Arkansas and should remain north of the TAF sites for the next few hours. However, redevelopment is expected by late morning or early afternoon across much of Southeast Oklahoma and East Texas. The next round of showers and thunderstorms will move eastward and will likely affect most TAF sites with the exception of KMLU. The precip should once again become confined to Southeast Oklahoma and Southwest Arkansas by 26/06z, but a complex of thunderstorms may move into the area from the north late in the period. Flight conditions will vary considerably. MVFR/IFR ceilings are ongoing across portions of Western Louisiana and much of East Texas, but the clouds should lift back into the VFR range by 25/15z. However, conditions will likely deteriorate again as thunderstorms impact the terminals. VFR conditions are expected after the precip ends, but light winds and a very moist low-level airmass should result in low clouds and MVFR/IFR ceilings at most terminals after 26/06z. CN && .PREV DISCUSSION... /issued 342 AM CDT Tue May 25 2021/ SHORT TERM.../Today through Wednesday/ The next in a long series of shortwave troughs, which is currently over Western North Texas, will generally move easterly today and over locations north of Interstate 30 by early this evening. Scattered showers and thunderstorms are already ongoing across Northern and Northeast Texas. An outflow boundary will also move eastward today from an ongoing thunderstorm complex in Western North Texas. The shortwave trough will provide enhanced vertical ascent for convective development, while the outflow boundary serves as a focus, especially along and north of the Interstate 30 corridor. Convective coverage should rapidly expand by late this morning and early this afternoon across much of the area, with high PoPs across most of the region west of a line roughly from Toledo Bend Dam to Camden AR. Abundant deep layer moisture remains in place, and the showers and storms will likely be efficient rain producers. Storms in North Texas have already been showing a tendency for training, and that will like remain an issue through the day. Given the saturated soils in place, this could lead to some isolated flash flooding concerns, especially in Southeast Oklahoma, Southwest Arkansas, and Northeast Texas where lift will be maximized from the shortwave trough and the outflow boundary. This round of convection should gradually diminish somewhat after sunset with the loss of diurnal instability, but scattered showers and thunderstorms will likely persist across the northern half of the area through the overnight and early morning hours of Wednesday. It's worth noting that the GFS and EMCWF are much more aggressive with rain chances tonight through Wednesday compared to the NAM, which is very dry. The GFS is the most bullish, but even the ECMWF suggests thunderstorms will move into the area from north to south as another convective complex dives southeast across Oklahoma and into Texas. PoPs should generally remain confined to areas north of Interstate 20 between midnight tonight and noon Wednesday, before convection becomes more scattered in nature across most of the area during peak afternoon heating tomorrow. All three models show another weak shortwave moving across Oklahoma during this time frame. The last several days have demonstrated that it doesn't take a great deal for convection to develop in this very moist and unstable airmass. Therefore, this forecast favors more of a blend of the GFS and EMCWF for rain chances on Wednesday versus the dry forecast of the NAM. LONG TERM.../Wednesday Night through Monday Night/ Northwest flow arrives by the middle of the week, ushered in on the backside of an upper-level low. This flow pattern, as it typically does, will carry embedded shortwaves and convective systems across the Red River Basin on the way to the Ark-La-Tex through the rest of the week into Memorial Day Weekend. Plans made this holiday weekend should take the daily chance of showers and thunderstorms into account. Until then, some subsidence aloft on the backside of the upper-level low will keep storms mostly at bay on Thursday. Simultaneously, a frontal boundary will cross the Great Plains by Friday, becoming stationary and serving as an instigating mechanism for a round of convective systems to propagate into our area with showers and thunderstorms by Friday afternoon. This frontal boundary will continue south overnight, potentially across the I-20 corridor, with a more vigorous shortwave aloft set to arrive by Saturday afternoon that delivers another chance of showers and thunderstorms with it. This frontal boundary will continue to slowly waver about the area on Sunday and linger across the Ark-La-Tex through Memorial Day, however, backside subsidence will once again keep conditions slightly drier as the holiday weekend ends. Impacts to temperatures by this pesky frontal boundary will be negligible as it arrives on Saturday with a moist, precipitation- moderated air mass across our northern zones. Southerly surface flow will persist through the rest of this week until then, maintaining near average to just above average temperatures with highs in the upper 80s and lows in the upper 60s. With moist soils, dew points in the upper 60s and lower-70s are likely, keeping conditions muggy for the foreseeable future. /16/ && .PRELIMINARY POINT TEMPS/POPS...
