000 FXUS64 KSHV 191809 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1209 PM CST Tue Nov 19 2019 .AVIATION... For the ArkLaTex terminals, a Chamber day everywhere with some cirrus arriving late. W/NW winds 5-10KT will slack and veer to N/NE overnight or calm and then prevail SE early and increasing to 5-15KT with gusts in TX esp. Climb attm winds are NW and weakening. FLs are still NW 50-90KT. An approaching upper level system will increase the S/SE winds all day with good moisture transport for some shwrs/isold TS late tomorrow with approaching fropa for a wet Friday. Beautiful weekend - early work week. /24/ && .PREV DISCUSSION... /issued 1040 AM CST Tue Nov 19 2019/ UPDATE... Bumped highs to upper 70s along I-20 corridor of E TX W LA. SHORT TERM.../Today/ Lots of sunshine and temps warming fast with the still dry air in place. Our W/NW winds will veer to N and NE late and right back to SE overnight. We are running in the upper 60s from Longview to Shreveport, and on a day like today adding 10 at 10a is a good likelihood for a final outcome. Especially with the low dew points and slacking and veering wind late. No other changes except to lower RH in the update process. /24/ PREV DISCUSSION... /issued 322 AM CST Tue Nov 19 2019/ SHORT TERM.../Today through Wednesday afternoon/ Upper-ridge to prevail through most of the short term forecast period. Aside from thin high cirrus, mostly clear skies to prevail across the region through tonight. Temperatures today to climb into the mid 70s with lows tonight around 50. Light and variable winds today to become southeast overnight as surface high pressure shifts east. Southerly flow to increase on Wednesday as a surface low deepens across the Texas panhandle. Increased moisture advection to provide mostly cloudy skies areawide on Wednesday. Showers possible across southeast Oklahoma and northeast Texas late Wednesday afternoon ahead of a cold front. Otherwise, afternoon high temperatures on Wednesday to climb into the low to mid 70s. /05/ LONG TERM.../Wednesday Night through Tuesday/ A lead shortwave will eject out of a deep closed low centered near srn NV Wednesday Night and rain chances will occur at least across areas mainly north of I-30 as the upper ridge axis moves east of the area. These rain chances may temporally abate for part of the day Thursday, before returning with more significant rainfall possible as the day progresses, although little if any rain expected south of I-20 until Thursday Night. Dynamics will be favorable for stg convection although this will be dependent upon whether the prefrontal development occurs. A cold front caught up in the deepening sw flow will begin to slowly move across the area durg the day Friday with a tapering off of cold rain west to east Friday Night. Drier and cooler wx on tap for the weekend ahead, with best radiative cooling on Sat Night, although overnight lows may hold just above the frzg mark for much of the area. Moisture will return as another longwave trough quickly digs further south than the previous rain event. Too early to break down pops in this period with low chances for time being beginning Monday Night./07/. && .PRELIMINARY POINT TEMPS/POPS...
