Severe (D2) drought conditions expanded south and east across portions of Northcentral Louisiana during the third week of November, encompassing much of Union, Lincoln, and Caldwell Parishes.

What happened
The episode as NWS SHV wrote it up.
Severe (D2) drought conditions expanded south and east across portions of Northcentral Louisiana during the third week of November, encompassing much of Union, Lincoln, and Caldwell Parishes. This was in response to significant rainfall deficits that accumulated since the start of September following the departure of the remnants of Tropical Storm Harvey. Only two and a half to three and a half inches of rain fell during the Fall Months (September-October-November), which was nearly ten inches below normal and less than 25% of normal. As a result of the drought, stock ponds receded significantly and numerous trees across the area were significantly stressed and began losing their leaves prior to the first freeze in late October.

Area forecast discussion, Nov 21, 11:21 PM CST, 39 minutes before
Area Forecast Discussion National Weather Service Shreveport LA 1121 PM CST Tue Nov 21 2017 .AVIATION... As expected, clouds beginning to break up across our airspace as drier air continues to funnel into the region from the north. Still can't rule out a brief MVFR ceiling near 3kft for the next couple hours across all terminal location with the exception being the TXK terminal with cloud cover remaining south of that location for the remainder of the night. Clouds will continue to thin overnight and should have SKC conditions across all terminal near or shortly after sunrise. North winds will increase during the day Friday with speeds at or near 10kts across most locations before decoupling late Friday Aftn/Evng. Thin cirrus should increase from west to east across our airspace late Friday Aftn/Evng as well. 13 && .PREV DISCUSSION... /issued 946 PM CST Tue Nov 21 2017/ UPDATE... To add pop/wx over our E Texas counties and tweak sky into Wed. DISCUSSION... Radar is showing a pretty good little crop of popcorn showers with a strong back door push now. Our 88D VAD wind profiler is showing N/NE flow up to 6-7kft. The showers over Deep E TX are moving quickly S/SW and will clear the area by around midnight. Adjusted sky this evening and went overnight into tomorrow with clearing skies to accompany this frontal push over the region. Winds still look to pick up in the coming hours with wind working down to sfc over AR and LA especially as we are calm or light N at this time. /24/ && .PRELIMINARY POINT TEMPS/POPS...
