Area Forecast Discussion National Weather Service Little Rock AR 138 PM CDT Thu Apr 20 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Saturday) Issued at 136 PM CDT Thu Apr 20 2023 To begin the period, a large upper level low continues to track across the northern Central Plains. This will drag a frontal boundary across our area this afternoon with PoPs increasing as we head into the afternoon and overnight hours. Strong to severe storms are possible with this system with hail and damaging winds the primary concern. Heavy rainfall is likely the greatest concern as most deterministic and ensemble models bring in two to three inches of rain across much of the state with some locations seeing locally higher amounts. Calm and drier conditions are expected Friday night into Saturday. As mentioned above, severe weather will be possible across much of the state this afternoon and evening as showers and storms begin to move into the state. While the chance for tornadoes are not zero, it is very low as the main concern is damaging winds and hail. Any discrete cells out ahead of the main line will have the greatest chance of producing hail, but as we approach the evening hours... storms will likely develop into a QLCS. By then, damaging winds will take over as the primary concern. The special 18Z upper air sounding from our office (LZK), showed an environment fully supportive of severe storms but by no means extreme ...CAPE values of 1800+ J/kg and dewpoints in the low to mid 60s. With that said, wind shear seems to be on the low side as SRH values are <150 m2/s2. As mentioned above, heavy rainfall is likely the greatest concern as a widespread two to three inches could fall across portions of the state with locally higher amounts possible. Additionally, the 18Z special sounding already shows PW around 1.30 in. with high-res models indicating that value could get to be 1.50+ in. across portions of the state. With already saturated soils and above average rainfall so far this year, flash flooding will be an elevated concern through Friday morning. Please remember, do not drive through flooded roadways and make sure to give yourself additional travel time to get to and from your destination. High temperatures are expected to be in the upper 60s to mid 70s across the state Friday and Saturday. Overnight low temperatures are expected to be in the 40s to upper 50s. Please continue to check back in for updates/changes to the forecast and be sure to follow reliable weather sources to get your weather information. && .LONG TERM... (Saturday Night through next Thursday) Issued at 136 PM CDT Thu Apr 20 2023 Broad longwave H500 troughing wl be deamplifying over much of the CONUS to begin the PD, as the primary closed upper low shifts to the N/E into the Great Lakes and Canadian provinces. At the sfc, a cdfrnt wl be clear of the state w/ broad sfc high pressure settling into the Cntrl and Srn Plains. A surge of continental air will be prevalent through much of the Cntrl CONUS, w/ below-normal temps knocking on the door of Nrn AR Sun morning. Most guidance continues to suggest temps in the upper 30s wl be seen by portions of far Nrn AR and the higher terrain of the Ozarks. Confidence is still low on freeze potential attm. By the return of the new work week and thru the remainder of the fcst PD, a more unsettled pattern is set to unfold. Sfc high pressure wl quickly depart to the Ern US, and weak/broad sfc cyclonic flow wl quickly develop over much of the Srn Gulf Coast region. A sfc baroclinic zone is progged amongst the fcst sfc mass fields, w/ much of AR residing on the cooler side of this bndry, positioned from the AR/TX panhandle region, E-S/E towards the ARKLATEX vcty. The bndry wl serve as a focus point for enhanced PoPs thru the early half of next week. Additionally thru the early part of next week, an H500 shortwave is set to come ashore over the PAC-N/W and quickly dig/pivot into the Four Corners Region. Wed and thru the remainder of the PD, this upper-lvl wave wl quickly interact w/ antecedent low-lvl cyclonic flow, and a more organized sfc low wl begin to take shape, w/ the primary low moving S/wrd towards the Gulf of Mexico. This wl further cement most of AR on the cold side of this low, w/ Nrly winds keeping temps near slightly below normal ranges. However, the influence of the sfc low & initial baroclinic zone along w/ the later approaching upper shortwave wl keep high Chc PoPs in place for much of the FA thru most of next week. A lack of Srly flow and prominent sfc heating potential should keep any severe threat minimal, however some isolated bouts of thunder may be possible later in the week as the upper wave traverses thru the FA. Otherwise, a wet and cooler than normal week is on deck for much of Arkansas. Something something...April Showers, right? && .AVIATION... (18Z TAFS) Issued at 1214 PM CDT Thu Apr 20 2023 Low clouds continue to move into the state as conditions will continue to deteriorate through the afternoon and evening hours. Current VFR/MVFR conditions are expected to become IFR conditions as a line of showers and storms move through the state. With it, it will bring the chance for heavy rainfall and possible VIS restrictions. Showers will continue through early Friday morning. Winds could be gusty at times. && .PRELIMINARY POINT TEMPS/POPS...
