000 FXUS64 KSHV 220544 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1144 PM CST Fri Feb 21 2020 .AVIATION... For the ArkLaTex terminals VFR w/ few cirrus bcmg BKN during Sat and SCT ocnl middeck. ESE winds early on Sat will veer S/SE mid to late day with 5-10KT and few gusts as high pressure moves away. Attm, our climb winds are light NE5-15KT and back to NW flow w/ increasing speeds abv 10kft up to 120KT max at FL320. The clouds continue to gather late Sat/Sun with an upper low bringing MVFR/IFR w/ shwrs/BR late in the wknd/early Mon. SW sfc wind Mon shift NW w/ fropa late day and nice weather pattern midweek. /24/ && .PREV DISCUSSION... /issued 939 PM CST Fri Feb 21 2020/ SHORT TERM.../Tonight/ Clear and calm for most sites with air temperatures in the low to mid 30s, with Ruston the coldest just under freezing. A few sites have a little Easterly component of wind and are consequently running in the upper 30s to right at 40 the warmest at Tyler and Natchitoches. So, expect a frosty windshield overnight with temps closing in now on frost formation. No changes needed to the overnight package aside from a few changes of current readings that where running a little warmer this last hour. /24/ PREV DISCUSSION... /issued 334 PM CST Fri Feb 21 2020/ SHORT TERM.../Tonight through Saturday Night/ Surface high pressure to become better established across the region overnight. Additionally, upper-ridge to the west to maintain subsident flow aloft allowing for clear skies areawide. Radiational cooling to allow overnight low temperatures within this arctic airmass to fall into the upper 20s to lower 30s tonight. Surface high to shift east late tonight allowing for light southerly winds by daybreak with patchy frost possible. High clouds to stream east across the region on Saturday with high temperatures forecast to climb into the mid 50s. Otherwise, expect increasing cloudiness on Saturday night as upper-flow becomes zonal. Under mostly cloudy skies, much warmer overnight low temperatures around 40 degrees expected on Saturday night. /05/ LONG TERM.../Sunday through Thursday Night/ Clouds will be quickly increasing and thickening on Sunday as a fast- moving disturbance approaches in relatively zonal flow aloft. This disturbance will not have a great deal of low level moisture to work with, but it will impart substantial atmospheric lift and induce isolated to scattered light rain showers in the Arklatex by afternoon. Expect the coverage of these mainly isolated to scattered showers to increase over the entire Four State region Sunday night, especially north of the I-20 corridor where some embedded rumbles of thunder cannot be ruled out. A surface frontal system maturing underneath the disturbance aloft will drag a front into the region on Monday with the front clearing to the east later Monday night. There might be a window for marginal low level instability to develop along and ahead of this frontal zone in our eastern zones midday through early afternoon Monday, but at this point the prospect for anything more than isolated storms looks low. All the precipitation should clear to the east by late Monday night with an expected window of partly cloudy skies and near normal temperatures Tuesday - just before a stronger cold front moves in for Tuesday night. This front could be accompanied by some brief light rains and we will have to watch the late Tuesday night period to see if some overlap of near to below freezing temperatures and lingering precip gains traction in the model consensus. For now, we just anticipate liquid rain and no wintry weather as the bulk of the chilliest air holds off until the precipitation is gone. The air mass in the wake of this front will deliver temperatures at least around 10 degrees below normal for Wednesday and Thursday of next week, but skies should fortunately be mostly clear. /50/ && .PRELIMINARY POINT TEMPS/POPS...
