SHORT TERM. /Rest of Today/

The morning sfc analysis indicates drier air continuing to build S across E TX/extreme Nrn LA this morning, just behind a stationary frontal bndry extending from Upper SE TX into Cntrl LA. The intrusion of the drier air into portions of E TX/NW LA has lifted vsbys across much of the existing Dense FG Adv. area, with additional improvement expected through midday. Thus, have cancelled the Dense FG Adv. a bit early, although some FG may linger through midday before completely lifting. Although the water vapor imagery does not depict the earlier shortwave trough over the Red River Valley, there are remnants of the trough oriented along the leading edge of the deep dry air aloft over much of E TX/SW AR, which will quickly spill E across N LA through early afternoon. The mosaic radar imagery indicates an extensive areas of -RA still persisting over much of N LA, with multiple sfc obs indicating measurable rain along this elevated moisture tongue N of the stationary frontal bndry.

Have beefed up pops through the remainder of the morning to mid and high chance for N LA, tapering pops off a bit to low chance/slight chance across E TX/Srn AR. Have retained slight chance pops for the afternoon for much of E TX/N LA/extreme Srn AR, as the short term progs continue to suggest areas of -DZ or isolated areas of -RA possibly redeveloping within a weak isentropic regime N of the sfc front. The post-frontal low stratus remains progged to linger through the day, although the stratocu may scatter some by afternoon across portions of McCurtain County OK and the Nrn sections of SW AR. With the NE winds and lingering low stratus/damp grounds today, have lowered max temps a cpl degrees across much of the area. While the weak cold advection will continue this evening, the low stratus will not be able clear the region before a SErly low level flow returns after 06Z tonight.

Zone update already out . grids will be available shortly.

PREV DISCUSSION . /issued 438 AM CST Fri Jan 22 2021/

AVIATION .

Tricky TAF package this morning with dense fog having set in at the TYR/GGG/SHV and ELD terminals. Precipitation is moving out for the most part but with a stalled frontal boundary across near the LFK terminal this morning, may be a while before we see these VSBYS and VV002 ceilings lift. Will prevail VLIFR VSBYS and LIFR to VLIFR through 16z and will show a gradual improvement to MVFR VSBYS and IFR ceilings by 18z at these terminal locations. MVFR ceilings by this afternoon may be a stretch across most locations but have more confidence in the TXK and maybe the ELD terminals seeing these conditions but did trend the afternoon ceilings toward low MVFR categories towards the afternoon hours. Kept MVFR ceilings prevailing overnight areawide except for the TXK/ELD terminals where we should see VFR ceilings but with ceilings near 8-10kft.

Look for NE to ENE winds today near or less than 10kts with those conditions prevailing overnight as well.

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.
