Area Forecast Discussion National Weather Service Shreveport LA 949 PM CDT Thu Sep 23 2021

SHORT TERM. /Tonight/

It is a gorgeous night out with lots of stars and air temperatures in the upper 50s and low 60s. Our winds are calm now and will trickle in E or SE very light after midnight, especially in TX counties as high pressure start to slide eastward. We are looking good for the forecasted lows in the low to mid 50s area wide with no changes needed anywhere. The cool surface high pressure will be exiting stage right early tomorrow and a slow, but steady warming trend will commence early. However, lows will take all weekend to get back to average, but our highs this time of the year should be in the upper 80s and a few sites will reach for that on Friday afternoon and then each day this weekend. /24/

PREV DISCUSSION. /issued 707 PM CDT Thu Sep 23 2021/

AVIATION .

For the ArkLaTex terminals, SKC will see encroaching cirrus as upper ridge expands behind the exiting sfc air mass that will give us one more cooler than average night. L/V wind or calm will grace most of the overnight hrs, but S5KT will begin to filter into TX terminals before daybreak and then nearly area wide S 5-10KT for the aftn. Cirrus may increase, but that is all for Friday. Moisture return will bring MVFR 10-13Z vsbys this wknd. Dry forecast until Tues for us, but KLFK may see a shwr 00Z. /24/

PREV DISCUSSION . /issued 254 PM CDT Thu Sep 23 2021/

SHORT TERM . /Tonight through Friday Night/

Surface high pressure will remain over the region this afternoon through early Friday morning, with broad upper-level ridging across the SW CONUS keeping dry northwesterly flow aloft over the area. However, models continue to suggest some high cirrus will move into the area from the west late this evening. This could limit radiational cooling a bit, but still expecting below normal overnight temps, with lows generally in the low to mid 50s.

The center of the high will start to shift eastward on Friday, allowing for light southerly winds to return across the western half of the region. This will likely result in a slight warm-up across East Texas and SE Oklahoma, along with portions of SW Arkansas and NW Louisiana. Afternoon highs will climb into the upper 80s in those areas, with mid 80s across the remainder of the CWA. Dry conditions should continue as the SW Upper Ridge is expected to nudge a little more eastward into our region, but the high cirrus will likely hang around through Friday evening. Expect slightly below temps again Friday night/Saturday morning with lows in the mid to upper 50s./20/

LONG TERM . /Saturday through Thursday/

The next longwave trough remains progged to amplify as it digs SE E of the MS Valley into the OH and TN Vallies Saturday, which will act to reinforce the dry NW flow aloft over our region. This trough passage will not have any frontal component to it though as the stronger upper level flow will remain well off to the NE, but sfc ridging will remain dominant over the region before gradually sliding off to the E of the Lower MS Valley Saturday night. A light Srly return flow will commence by Sunday, although strong mixing of the drier bndry lyr will result on one more day of comfortable RH's before the air mass begins to modify with the increasing low level moisture advection from W to E late Sunday night through Monday. Max temps will continue to a warming trend as well as we move into the new work week, with readings more typical of what is normal for this time of year. While the returning cu field should remain just SW of the area over SE TX Sunday afternoon, some cu/stratocu may return to portions of E TX Sunday night, before increasing in earnest over more of the region Monday.

Flat upper ridging over the Srn Plains will begin to amplify some as it expands E into the Ozarks and Lower MS Valley Monday, ahead of a closed low that will drift E into Cntrl NM. A weak seabreeze is progged to develop along/N of a warm front over SE TX Monday, which may advance N into portions of Deep E TX during the afternoon before diminishing by sunset with the loss of heating. Have maintained slight chance pops for this area, although additional isolated convection may redevelop late as the warm front lifts NNE into the region. The warm/moist sector should overspread much of the region by Tuesday morning, with ripples in the developing SW flow aloft ahead of the closed low expected to focus the potential for isolated to scattered convection over the area. Have maintained low to mid chance pops over the SW half of the area Tuesday, before diminishing Tuesday night with the loss of heating. The closed low is progged to open up Tuesday night and become absorbed in the SW flow ahead of the next developing upper trough/potential closed low, with the residual troughiness from the ECntrl OK into the Srn Plains contributing to enough forcing for additional scattered convection over the region Wednesday, although uncertainty exists with how far E this convection will develop given the varying solutions of the position of the trough. The ECMWF is much weaker and amplifies the strong ridging aloft N into the Great Lakes/MS Valley, while the GFS is slower with the amplifying ridge thus resulting in a greater influence of the residual trough over the area. By Thursday, this aforementioned ridge should amplify enough such that any convection may be a bit more isolated/widely scattered, with drier conditions trending by the end of the work week as we enter the first few days of October. /15/
