NWS Little Rock, AR wrote its last area forecast discussion before the first event at Aug 31, 6:03 PM CST, 5 hours 57 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 703 PM CDT Fri Aug 31 2018 .AVIATION... Showers near KLIT and KPBF will continue for the next hour as they move eastward along an outflow boundary, otherwise quiet weather will be seen at all other TAF locations overnight. VFR conditions will prevail at all sites through the evening. Some MVFR conditions will be possible where fog develops, primarily after 06Z. By 14-15Z VFR conditions are expected to return at all sites. Isolated showers/storms are possible Saturday afternoon near the southern terminals. Winds will be southeasterly, with sustained speeds around 10 knots or less. && .PREV DISCUSSION...(ISSUED 244 PM CDT Fri Aug 31 2018) Short Term...Tonight through Saturday Isolated convection now starting to fire up mainly over eastern Arkansas along an upper shear axis that is centered between two upper level highs. Convection is being aided by diurnal heating and high moisture content. Much like the storms of the past few days, winds remain very light in the lower levels and any storm that develops will be a rather efficient rain maker. The aforementioned highs are entered over western Oklahoma and along the mid Atlantic coast respectively. The upper high to our east will start to build over the state through the period and become the dominant weather feature. Precipitation coverage Saturday will be fairly similar to what will be seen this afternoon and the evening. However, the overall coverage is expected to be little more widespread and further to the west. Precipitation coverage will increase on Sunday as dynamics, as weak as they are, will be are aided by an upper impulse moving around the periphery of the ridge. Seasonal temperatures are expected, but moisture levels will remain elevated. As a result, heat indices will be in the mid 90s to near 100 degrees each afternoon. Long term...Sunday Night Through Friday An area of high pressure aloft remains over the east coast Sunday night. An upper trough moves into the northwest U.S. Monday and moves east through the northern Plains Tuesday and Wednesday. The upper ridge remains in place through the period and builds to the west somewhat on Thursday and Friday. With high pressure east of Arkansas, moisture will continue to be pushed into Arkansas from the Gulf of Mexico. Occasional impulses will rotate around the high and bring mainly diurnal showers and thunderstorms to the area. Highs in the 80s and 90s and lows in the 60s and 70s will continue. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...JONES
