Area Forecast Discussion...Updated National Weather Service Little Rock AR 1245 PM CDT Wed Mar 28 2018 .Aviation... An area of rain and showers, with some isolated thunder, will continue to move east over AR and affect most Taf sites. Lighter convection over northern AR, while better over central and southern AR. Ceilings will be mostly MVFR, with areas over the south VFR while patchy IFR in spots. This evening and overnight, more areas of MVFR ceilings with patchy IFR with fog, also with continued chances of rain and showers. Most thunderstorms will be confined to southern AR. Winds will be south to east at 5 to 10 mph, becoming more east to north tonight, then northeast to northwest into Thursday. (59) && .Prev Discussion.../ Issued 1045 AM CDT Wed Mar 28 2018/ Overall forecast on track. Area of light to at times moderate rain continues to move east northeast across AR. Have seen rain amounts from a few tenths to around a half in spots over the last 6 hours, while 24 hour amounts, the most in southwest AR of over 1 inch, then 0.25 to 0.75 in many other central and southern locations, while the lowest in the north around 0.10 or less. 24 hour amounts were around 1 to 2 inches over much of AR, with some locals less, while some more especially in the northwest. At the surface, a frontal boundary was over central AR, around Mt Ida, to Russellville to Jonesboro. A bit drier air was north of the boundary with dew points in the 50s, while south of it, dew points in the 60s. The upper wind flow was nearly parallel to the boundary, so it will take into Thursday before enough wind energy and the upper dynamics move it east to push the boundary out of AR to the east. Until then, additional upper lift will move across AR, and keep a good chance of rain in the forecast. This event is a more rain and shower, with only isolated thunder expected. Also, the heavy rain threat will shift more to south and southeast AR, as the upper dynamics gradually move east. Flood watch may be trimmed later today on the northwest side as the heavier rain potential shifts east to southeast. Clouds will hold today and highs will be from the 50s north, to 60s central, and some 70s far south. Late morning update will mostly fine tune rain chances and amounts this afternoon to evening. (59) && .Prev Discussion.../ Issued 640 AM CDT Wed Mar 28 2018/ .SHORT TERM...Today Through Thursday Night Generally light to moderate rain was noted this morning across much of Arkansas, especially the southeast half of the state. Rain was heaviest in the southwest. Satellite showed enhanced clouds/thunderstorms in Texas, and this was cutting off some of the more significant moisture locally. Data shows rain continuing today/tonight/Thursday, with rumbles of thunder at times. Precipitation will be the most widespread/significant across the southern/eastern counties. One to two inch amounts appear likely, with locally over three inches. Simulated radar is showing another round of thunderstorms from eastern Texas into northern Louisiana this evening, and this could hold down amounts somewhat. With the potential of heavy rain in the southeast, and above average soil moisture due to excessive rain in late February, a Flood Watch remains in effect. Precipitation in the near term will surround a nearly stationary front close to the Arkansas and Louisiana border. A wave of low pressure will track along the front, and will head from central Texas to northeast Arkansas by Thursday morning. As the low exits toward the Ohio and Tennessee Valleys, it will pull the front through the region and rain will taper off Thursday night. && .LONG TERM...Friday Through Tuesday Dry conditions will be in place at the start of the long term portion of the forecast with the flow aloft zonal to northwesterly in nature and high pressure in place at the surface. Near normal temperatures will be in place initially, but as surface high pressure shifts east by Saturday and a cold front approaches from the west, temperatures will warm further by Saturday afternoon. The cold front will make its way across the state Saturday evening into Sunday morning. Rain chances will accompany the front. In the wake of the front, as surface high pressure briefly builds in, cold air will filter into northern parts of the state. At this time, forecast lows Sunday and Monday morning are in the mid 30s for the northern 2-3 rows of counties. As we get closer to this timeframe, surface temperatures will have to be monitored for potential frost/freeze impacts in these areas. By early next week, the surface high shifts east and the flow aloft becomes zonal. With occasional disturbances passing over the area some rain chances will remain in the forecast and temperatures will be near to slightly above normal. && .PRELIMINARY POINT TEMPS/POPS...
