176 FXUS64 KSHV 090009 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 709 PM CDT Tue Oct 8 2019 .AVIATION... For the ArkLaTex terminals all is well. NE5KT SFC is going calm already with SKC, patchy BR at daybreak not out of the question esp KLFK; otherwise VFR. Aloft, NE5-15KT is shallow and slacks and backs to Westerly before 10kft with only 10-20KT for flight levels. High pressure moving NE will allow return flow off the Gulf and SFC and low level winds to veer to E/SE on Wednesday 5-15KT. Aloft the NE shallow veers to SE and the Westerlies column will back to increasing SW flow ahead of our next big storm on approach Friday. /24/ && .PREV DISCUSSION... /issued 358 PM CDT Tue Oct 8 2019/ SHORT TERM.../Tonight through Wednesday Night/ Surface high pressure centered over the New England States and extending southwest across the Ohio Valley into the ArkLaTex to maintain cool conditions across the region through Wednesday. Overnight low temperatures are forecast to fall into the lower 50s areawide tonight with high temperatures on Wednesday forecast to climb into the lower 80s. Surface high and upper-level ridge to shift east on Wednesday evening allowing for a return southerly flow and gradual warming trend. Temperatures on Wednesday night to fall into the lower to middle 60s. Otherwise, mostly clear skies to prevail through the period. /05/ LONG TERM.../Thursday through Tuesday/ Deep upper troughing creating stg warm air advection on Thursday with aftn highs mainly in the upper 80s to lower 90s, except possible middle 80s far north where some cumulus clouds may merge into ceilings by later in aftn, although keeping isold pops just nw of the cwa until around sunset. With dewpoints rising to the middle and upper 60s, heat index readings may rise to the middle to upper 90s. However, with the strongest cold front thus far of the season beginning to move swd into the area Thursday eve, stg lift along front will ignite tstms, although svr potential may be reduced due to the timing of this activity in area as stgr dynamics remain well to the north where upper low tracks across Iowa on Friday. Winds from the north behind the front will be stronger than the southerly winds ahead of the system and may warrant a lake wind advisory on Friday. Between the wind and a thick layer of low clouds contained within steep low lvl inversion, temps may actually drop thru the daytime, along with dewpoints. Rain chances will remain high behind the front and may be enough large scale lift for elevated tstms above the inversion. Once the clouds clear up and winds subside some, temps will quickly fall Friday eve with lows reaching the 40s across at least nrn portions of the region. Saturday night may be the coldest night at some locations with 40s for at least most of the region and some upper 30s possible north as skies go into sunset already clear and winds may fall to near calm. Daytime temps on Saturday will remain cool in the mid to upper 60s and then moderate back into 70s by Sunday. A warm front is expected to lift back northward into the area on Monday bringing a chance for more rain to the area. /07/ && .PRELIMINARY POINT TEMPS/POPS...
