46What 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 Aug 19, 3:25 PM CDT, 2 hours 42 minutes earlier.
Area forecast discussion, Aug 19, 3:25 PM CDT, 2 hours 42 minutes before
Area Forecast Discussion National Weather Service Little Rock AR 325 PM CDT Sun Aug 19 2018 .SHORT TERM...Tonight Through Tuesday Current VIS satellite imagery showed showers and thunderstorms developing along a warm front that was slowly lifting north on Sunday afternoon. Low level clouds were seen moving northwest depicting a southeast flow in the lower levels, however aloft, persistent northwest flow over the last couple weeks had backed to the southwest in response to a surface low near central Kansas. SAT imagery depicts well defined drying at all levels behind the cold front across central KS/OK. Abundant moisture continued to advect into AR from the Gulf of Mexico. Temperatures this afternoon were in the 70s and 80s north of the front, to 80s and 90s south of the front. Dew points are in the lower to middle 70s. Theta E gradient was highest across central AR near and south of the boundary. In this area, ML CAPE values were 2000 to 3000 J/kg with SB CAPE approaching 4500 J/kg. PWATS were 2.0 to 2.1 inches along and south of the warm front. 0-3km helicity values should increase through the evening from less than 100 m2/s2 to 150-300 m2/s2 across central and northwestern AR. Convection is expected to develop across AR through the afternoon. Given all the environmental conditions already in place, severe storms may be a concern heading into this evening through tonight. Strong damaging winds and large hail are the main threats, however given winds turn with height near this low, an isolated tornado or two can not be ruled out, mainly across the northwest portion of the state. Meridional flow is expected to persist in the upper levels through much of the period. Heading into Monday the upper low begins to lift towards the northeast as it deepens. Across our area this upper low will provide continued forcing for ascent across much of the CWA. This forcing will remain in place, continuing rain chances, unitl the front passes late Monday into Tuesday. Expect drier and slightly cooler air to filter in behind this front. && .LONG TERM...Tuesday Night Through Sunday An upper ridge will be over Texas to begin the period with northwest flow over Arkansas and up through the Midwest. The northwest flow continues over the area through the period with several impulses coming around the ridge. The long term forecast will begin dry and slightly cooler with surface high pressure over the area. The high moves off to the northeast Thursday and will allow a weak system to move through the northwest flow and bring a chance of showers and thunderstorms. Rain chances will continue on Friday and Saturday then chances decrease Sunday. High temperatures will be mainly in the 80s Wednesday through Friday, then more widespread 90s return for next weekend. && .PRELIMINARY POINT TEMPS/POPS...
