Area Forecast Discussion National Weather Service Shreveport LA 1053 PM CDT Tue Mar 31 2020

AVIATION.

For the ArkLaTex terminals, expecting VFR with calm winds over- night, but some patchy BR around daybreak. Otherwise, our SFC winds will resume 13-15Z from ESE 5-10KT. Expect less low clouds for Wednesday and more high clouds streaming our way with the next weak fropa bringing more showers late week and then improving some for the wknd, but the wet pattern persist for early next week./24/

PREV DISCUSSION. /issued 1016 PM CDT Tue Mar 31 2020/

UPDATE . Minor changes to a few low temps and patchy fog areas.

SHORT TERM . /Tonight/

Areawide air temps are pretty cool already this evening, but near saturation by a degree or two in about half of the available obs. The dew points are running a little higher than forecast and winds are very light or calm for most sites. Falling through the dew point may occur in a few sites, but not areawide with the calm wind. We have raised a handful of overnight lows with too far to fall based on the spreads. Otherwise, we have got some patchy fog for likely all zones for at least a short time around daybreak. /24/

PREV DISCUSSION . /issued 332 PM CDT Tue Mar 31 2020/

SHORT TERM . /Tonight through Tomorrow Night/

Unlike short-term discussions of yesteryear, there really isn't a whole lot to discuss weatherwise over the next 36 hours. The cold-front has finally pushed out of the area, allowing for dry air to filter in from the north. Dry air and clear skies can be expected to remain over the course of this short-term period. Temperatures tonight may be a little chilly to some, as temps will run in the mid 40s, with a slight rebound tomorrow night into the low 50s. Patchy fog may also be possible in some areas as the winds decouple. However, look for abundant sunshine and temperatures into the mid 70s area-wide tomorrow. /44/

LONG TERM . /Thursday through Tuesday/

Upper level ridging in place across the region Thursday will begin to shift E across the MS Valley by Thursday evening, with low level moisture advection expected to increase across E TX by afternoon. However, the short term progs have backed off on the SHRA development across this area by several hours, and thus have lowered pops to slight chance across SE OK/E TX before pops increase to chance Thursday evening as slightly better mid level forcing beneath the upper trough ejecting NE through the Cntrl/Nrn Plains, enters the area under increased moisture advection.

The progs continue to suggest a weak cold front beginning to shift SE across Ern OK into N TX Friday afternoon, with the ECMWF consistent with earlier runs in slowing the front in the higher terrain over Wrn AR Friday night, before sfc ridging over the Plains is able to reinforce this bndry SE through the region Saturday. This seems more plausible than the much faster GFS given the lack of any reinforcing flow aloft, although there is some agreement here that the better frontal convergence will exist across portions of E and S/SE TX, where perturbations in the flow aloft will help enhance forcing aloft by mid/late afternoon through the evening when instability is maximized. Although the progs suggest the more organized convection will remain WSW of the region late Friday afternoon, still can't rule out at least an isolated severe threat over portions of E TX in the late afternoon/evening where better frontal convergence will exist, before the threat diminishes late with waning instability. Did continue the trend with ramping up pops to likely from W to E across the region Friday night, with the general consensus in the convection diminishing during the day Saturday. Temps look to cool to more seasonal levels Saturday in wake of this weak cool frontal passage, with weak sfc ridging building S into the area in its wake. Did tone down pops to slight chance Saturday night/Sunday morning to reflect the dry signal that the ECMWF/GFS/Canadian are advertising, which is more in line with the more consistent ECMWF that was depicted Monday.

Upper level ridging is expected to build back N across the region into the MS Valley Sunday, thus promoting a warming trend for the latter half of the weekend into early next week, with the feature shifting E of the region by Sunday night resulting in return SW flow aloft. This will result in additional perturbations in the flow to eject ENE across the Srn Plains and enhance convection development late Sunday through Monday across the region. Although these perturbations may initially flatten the ridge, the ridge itself looks to amplify back N across the region/MS Valley and Gulf Coast states by Tuesday before shifting farther E just beyond the extended period, which may result in another period of active weather for mid and possibly late week. /15/

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
