Area forecast discussion, Aug 18, 2:41 PM CDT, 1 hour 3 minutes before
Area Forecast Discussion National Weather Service Little Rock AR 241 PM CDT Sun Aug 18 2019 .Short term...Tonight through Tuesday Mainly diurnally driven convection continues to fire up at this time with the largest concentration of storms over the western part of the state. Atmosphere remains supportive of convection through the evening hours with a few of the stronger storms capable of producing gusty winds and to a lesser extent, large hail. Heat indices continue to flirt with advisory criteria but with cloud cover and developing convection, will hold off on any heat related headlines at this time. Upper ridging currently to the west of the state will build into the region during the remainder of the short term period. The area will be on the eastern periphery of the aforementioned ridge with a continuing chance of afternoon convection on Monday. Once again heat indices will be borderline for a heat advisory although it is some likely that it will be met briefly at the usual locations during peak heating. Ridge will expand eastward on Tuesday and any precipitation chances will be confined to the eastern sections of the forecast area. South to southwest winds will continue to pull gulf moisture into the area and with temperatures being a little warmer, heat related headlines will likely be needed. && .LONG TERM...Tuesday Night through Sunday Long term begins with a ridge of high pressure centered just to the west of Arkansas and surface high pressure to the east. Moisture will be on the increase on Wednesday ahead of a cold front moving towards the state from the north. Heat index values on Wednesday will be quite warm with values over 105. By Thursday the aforementioned cold front will make its way into the state and bring rain chances to the forecast. This front will stall across the area before completely washing out. This will keep rain chances in the forecast through the end of the long term. With the increased rain chances, temperatures will be kept in check with temperatures forecast at or below normal. && .PRELIMINARY POINT TEMPS/POPS... Batesville AR 75 94 76 96 / 20 30 10 20 Camden AR 77 96 76 98 / 10 20 10 20 Harrison AR 73 92 73 93 / 30 20 10 10 Hot Springs AR 77 95 76 97 / 20 20 10 10 Little Rock AR 77 96 77 97 / 20 20 10 10 Monticello AR 77 94 76 96 / 20 30 10 20 Mount Ida AR 76 95 74 96 / 10 20 10 10 Mountain Home AR 73 93 73 95 / 30 30 10 10 Newport AR 75 93 76 95 / 20 30 10 20 Pine Bluff AR 76 94 76 96 / 20 20 10 20 Russellville AR 76 96 76 97 / 20 20 10 10 Searcy AR 75 95 75 96 / 20 30 10 20 Stuttgart AR 75 93 76 95 / 20 20 10 20 && .LZK Watches/Warnings/Advisories...NONE. && Short Term...GOUDSWARD / Long Term...65
