Area forecast discussion, Aug 7, 5:30 AM CST, 4 hours 46 minutes before
Area Forecast Discussion...Updated for Aviation National Weather Service Little Rock AR 630 AM CDT Fri Aug 7 2020 .AVIATION... VFR conditions are expected through tonight. Showers and isolated thunderstorms will be noted through early this afternoon in western Arkansas. Surrounding the precipitation, mid and high clouds will be widespread, with scattered cumulus at 3000 to 4000 feet. Winds will mainly be south/southeast at 4 to 8 mph. Rain will have mostly dissipated by this evening, with some high clouds left behind. (46) && .SHORT TERM...Today Through Saturday Night A ridge of high pressure over the southern Plains will become more dominant in Arkansas as the near term progresses. On the eastern periphery of the ridge, a warm front will gradually lift to the north/east. Along and north of the front, scattered to numerous showers and thunderstorms are expected in western sections of the state today. Toward the Oklahoma border, some places could pick up a quarter to three quarters of an inch of rain. No severe weather is expected. Temperatures will continue to be at/below average. That will change. On Saturday, rain will be pretty much gone, and heat/humidity will become more of a factor. Afternoon heat index values will be well into the 90s to just over 100 degrees. Temperatures will be above average. && .LONG TERM...Sunday Through Thursday In the beginning of the long term period, broad upper-lvl anticyclonic flow will be present over much of the Srn US. Broad upper subsidence will translate to hot conditions at the sfc for the latter part of the weekend, with high temperatures approaching the mid-90s for much of the state. Precip chances will remain suppressed as well, and likely be limited to isolated diurnally driven showers/thunderstorms. By Tues, a protrusion from the polar jet to the N is progged to eject over the Nrn portion of the state. Upper divergence associated with the shortwave will provide forcing for more widespread PoPs over much of the state. The good news is, increased rain chances will help keep temperatures moderated, with highs falling back to the low 90s, and peak heat index values falling below 100F. Through the remainder of the period, Cntrl US ridging will reamplify, limiting PoPs to diurnal activity over the fcst area. && .PRELIMINARY POINT TEMPS/POPS...
