Area Forecast Discussion National Weather Service Shreveport LA 1150 AM CST Thu Feb 20 2020
A greatly improving aviation forecast is in store for our TAF sites, and across the Four-States region. We're starting out the morning in MVFR almost area wide, as low ceilings and precipitation are finally starting to exit the region. Behind this precip, look for dry air to filter in. This will result is improving ceilings, with bumps into VFR expected past 20/22z area wide. However, gusty winds will be possible at all sites through this evening. Look for those winds to decouple past 21/01z. /44/
PREV DISCUSSION. /issued 1005 AM CST Thu Feb 20 2020/
After reviewing the morning trends from ASOS stations around the area, it appears that the morning forecast package is still on track. Therefore, no update is needed at this time. /44/
PREV DISCUSSION . /issued 554 AM CST Thu Feb 20 2020/
AVIATION . IFR/low MVFR cigs in place to start the 12Z TAF period across the region will slowly begin to lift later this morning through the afternoon, as areas of -RA gradually diminishes from W to E from mid-morning through mid-afternoon. However, even as the -RA does clear, MVFR cigs will persist for much of the day across the area, with VFR cigs returning to the TXK/ELD terminals by mid/late afternoon, and the I-20 terminals of E TX/N LA by early evening, with LFK the last to return to VFR by mid-evening. These cigs should quickly scatter out this evening, with SKC returning areawide by/after 06Z Friday. NE winds 9-14kts, with gusts to 25kts, will diminish slightly to 8-12kts after 00Z. /15/

SHORT TERM . /Today through Friday/
SHRA remains widespread across the region this morning, but the end to the wet weather pattern is finally in sight as the morning water vapor imagery indicates much drier air entraining E across Wrn and Cntrl OK into NW TX beneath a SW to NE upper trough extending from Cntrl CO NE through the upper Midwest into the Nrn Great Lakes region. In fact, the morning mosaic radar imagery confirms this as the back edge of the -RA is diminishing across the middle Red River Valley of Srn OK into NCntrl TX. The short term progs and the 00Z CAMS remain in good agreement this morning with the drier air continuing to entrain E across much of the region later this morning through the afternoon ahead of the trough passage into the Mid MS Valley, Ozarks, and Red River Valley, with the -SHRA quickly diminishing from W to E by mid to late morning over all but the Srn/Ern zones, which should see an end to the rains by mid/late afternoon. Have maintained categorical pops this morning over Deep E TX/N LA/Scntrl AR, tapering pops back to likely and chance farther W across the remainder of E TX/SW AR/SE OK.
Meanwhile, the 09Z sfc analysis indicates weak sfc wave have developed along the old cold front extending just offshore the TX/SW LA coasts, NE into SCntrl and SE LA and Srn MS. These weak waves along the front, as well as the arctic sfc ridge that will build S into Wrn OK/Ozarks/Mid MS Valley, will result in a tightening pressure gradient across the region later this morning through the afternoon, but believe the low stratus overcast that will persist beneath the steep inversion noted on the 00Z KSHV raob that should linger through the afternoon will help limit the extent of mixing of the 35-40kt NErly H925 winds and thus have maintained winds just below Lake Wind Advisory criteria. However, gusts up to 25 mph will be possible before the winds begin to relax by early evening. However, the morning rains, low overcast, wet grounds, and gusty NE winds will not allow much warming to occur today from the morning low temps, as readings will have a hard time climbing another 5 degrees or so (and remaining near or shy of 50 degrees).
The post-frontal stratus shield should finally begin to thin from NE to SW late this afternoon through this evening, giving way to a clearing sky, with cold advection expected to commence by late evening ahead of the arctic ridging that will continue building Swd into the Srn Plains/Mid MS Valley. Near to below freezing temps are expected over much of the region by daybreak Friday, with the main story being the much drier air expected to mix SSW into the area. In fact, the deeper wedge of colder air will help mix dewpoints look to mix down into the teens/lower 20s Friday, and despite ample insolation, should maintain max temps in the upper 40s/lower 50s. With the modifying arctic ridge building into the region Friday afternoon/night, widespread freezing temps are expected areawide before a warming trend commences for the weekend.

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.
