BrownWhat forecasters said that day
The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Little Rock, AR wrote its last area forecast discussion before this tornado warning went out at Apr 4, 8:31 PM CDT, 1 hour 18 minutes earlier.
Area forecast discussion, Apr 4, 8:31 PM CDT, 1 hour 18 minutes before
Area Forecast Discussion...Update National Weather Service Little Rock AR 830 PM CDT Tue Apr 2017 .Discussion... Area of convection will gradually move east into the CWA this evening and an isolated severe storm will be possible, with mainly large hail and damaging winds the main threats. These storms were associated with an upper low pressure storm system moving through the region. Later tonight, the surface system and cold front will move across AR and push the storms to eastern AR, then on Monday out of AR. Some lighter convection may still be possible mainly over northern AR before the entire system moves out of the region. Models are consistent that winds will be elevated on Wednesday from the west and be 10 to 20 mph with gusts around 30 mph over much of the state, and a lake wind advisory will be issued for most of AR from mid-morning to the evening. Late evening update will fine tune convection chances, timing and include the lake wind advisory. (59) && .Prev Discussion.../ Issued 620 PM CDT Tue Apr 4 2017/ .Aviation... VFR flight conditions will start the forecast. An upper and surface low pressure systems, as well as a cold front, with move across AR tonight to Wednesday morning, and bring VFR ceilings with patchy MVFR ceilings with showers and thunderstorms. The main area affected will be northern AR. An isolated strong to severe storm may be seen. Winds ahead of the system will be southeast at 5 to 15 mph with some gusts to around 20 mph. Winds will become south to southwest later tonight, then west to northwest behind the cold front. Winds will remain elevated behind the front and be 10 to 25 mph with some gusts around 30 to 35 mph on Wednesday. Most of the convection will push east of AR during the day Wednesday. A low level jet will be present this evening and early into the overnight, and some wind shear may be seen at all Tafs. (59) && .Prev Discussion.../ Issued 254 PM CDT Tue Apr 4 2017/ .SHORT TERM...Tonight Through Thursday 19z subjective surface analysis indicates developing low pressure between Lawton and Oklahoma City, with a warm front extending northeastward to southwest Missouri. Strong pressure falls were noted near and to the north of the warm front. Satellite imagery indicates short amplitude yet potent short wave energy moving northeast into southwest Oklahoma. Convection is expected to develop quickly late this afternoon, focused on the warm frontal boundary. Forecast storm motion vectors indicate a northeast movement with storms that develop this afternoon. Much of this activity should affect areas to the northwest of the LZK forecast area. As the evening progresses, convection should obtain a more eastward movement, while overall intensity decreases with increasing stability. Gusty westerly surface winds are expected during the afternoon on Wednesday, in the wake of a cold front moving eastward through the mid south. Afternoon temperatures on Wednesday will average 15-20 degrees lower than those of this afternoon. && .LONG TERM...Thursday Night Through Tuesday A deep upper low pressure system will be over New England to begin the long term period with an upper ridge over the Rockies. The upper low will slowly move through the northeast U.S. through Friday. The upper ridge moves into the Plains for Friday and Saturday...then to the eastern U.S. for Sunday. Another upper low moves into the northern Plains Sunday but should move into the Great Lakes for Monday and Tuesday. Southwest flow will return to Arkansas for Sunday night through Tuesday. Models are in good agreement with a dry period Thursday night through Sunday with high pressure generally in control. The high moves east of Arkansas Sunday and moisture will return. A cold front moves into the Plains Monday and we will see rain chances increase over Arkansas on Sunday night and Monday then decrease on Tuesday. The cold front moves through Arkansas on Tuesday. After a cool Friday, temperatures will return to above normal values. && .PRELIMINARY POINT TEMPS/POPS...
