Area Forecast Discussion National Weather Service Shreveport LA 623 PM CST Tue Dec 10 2019

AVIATION.

Latest satellite imagery shows considerable cloud cover over much of the area, with some clearing skies across Ark-La-Tex and portions of east Texas. In addition, rain showers continue to to move across portions of deep east Texas and central Louisiana. The main concern for this TAF period will be for lingering MVFR to IFR cigs, generally along and south of I-20, improving from north to south through 10z Wednesday. For sites north of I-20, VFR conditions are expected through the period, with VFR conditions expected across the region after 10z. Light and variable surface winds are expected overnight through Wednesday afternoon across the area.

PREV DISCUSSION. /issued 253 PM CST Tue Dec 10 2019/

SHORT TERM . /Tonight through Wednesday Night/

Relief from this drenching cold rain is on the way for the Four- States region, but it's unfortunately going to be a trade off as below average temperatures are going to follow this soon to be vacated precipitation.

By this evening, what little rain our area will be seeing should be limited to the Grant, La Salle and Caldwell Parishes. Beyond that, the remainder of this short term period will be dry. However, in its wake this system will have cleared out a good portion of the cloud cover, and shifted the winds from the North. While high-temperatures on Wednesday will get up into the mid-50's, overnight low temperatures tonight and Wednesday night will be at, or below freezing area wide. Thankfully, the winds won't be too strong to give this cold a true winter bite. Expect the winds over this short term forecast to only reach sustained speeds between 5-10 MPH, with the stronger winds confined to our southeastern most areas. /44/

LONG TERM . /Thursday through Tuesday Night/

A weak disturbance aloft will be located across the OK/TX Pndl region of the country to start our Thu with this system expected to move ese across the Middle Red River Valley and into the heart of our region by Thu Evng. Low level moisture return remains pretty sparse with this feature but both the ECMWF and NAM 12z runs continue to paint a little more in the way of 8H moisture across our eastern third and therefore are trying to spit out some showers in association with this weak trough axis. Did not stray too far from this line of thinking that also coincides with the previous forecast.

Not seeing much in the way of a frontal passage in association with this trough by late week but instead, the trough will delay the return of southerly winds in the low levels until Friday. This will transpire ahead of a weak frontal passage it appears sometime during the day Saturday with a progressive westerly pattern with nearly zonal flow aloft oriented across the Southern Plains. Temperatures are trick for the weekend as the GFS during this same timeframe is depicting a returning warm frontal boundary for late Sat into Sun so tried to blend the two differing models concerning weekend temperatures. This discrepancy remains in the forecast for early next week between the models despite surprisingly good agreement concerning the ejection of our next weather maker in the form of a longwave trough exiting the Intermountain West Sunday Night and entering the Great Plains on Monday. While there is a large positive tilt to this next trough early next week, there should be enough forcing and moisture return, especially if the GFS solution comes to fruition with a returning warm frontal boundary, for high end chance pops beginning Sun Night and continuing through Monday before the precipitation and the effects of the trough exit our region to the east by Mon Night into Tue.

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.
