NWS Little Rock, AR wrote its last area forecast discussion before the first event at Sep 25, 5:40 PM CST, 1 hour 5 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 640 PM CDT Fri Sep 25 2020 .UPDATE... Updated to include the 00Z aviation discussion. && .AVIATION... Given little change in the air mass between last night and what is expected tonight, do expect MVFR to IFR BR and low stratus will develop again and reflected this at all terminals, especially in the 26/10-14Z window. Stratus may be slow to erode thereafter, so lingering restrictions are possible into the afternoon. Winds will range from S to VRB with speeds up to 10 kts and no significant gusts. && .PREV DISCUSSION...(ISSUED 248 PM CDT Fri Sep 25 2020) Short Term...Tonight thru Sunday Night... It looks like Arkansas will have a pleasant weekend, with afternoon high temperatures rebounding into the lower and mid 80's on both days. Some low clouds and fog will likely form again overnight. Dense fog was expected across much of the area last night, and for the most part it did not pan out. The notable exception was across the northwest counties, where visibilities dropped to near zero. While I do think fog will form in many areas tonight, I am not confident enough it will be dense enough and widespread enough for an advisory at this time. I will defer to the evening shift to monitor how things progress overnight. More than likely some cloudiness will linger in some areas through the morning hours tomorrow, otherwise plenty of sunshine should be on tap. A return flow from the Gulf should become more established, with southerly surface winds. The next system will be taking aim at the area as a cold front and associated trof drops down toward the area from the southern Plains. Earlier it looked like some showers and thunderstorms would move into the area Sunday night, but models are trending toward a slower entry of this system, and as such I have removed precipitation chances in most areas for Sunday Night. Extended Term...Monday thru Friday... The long term period will begin with an upper ridge over the west and east coasts. A large upper trough will be digging into the upper Midwest and Plains. This upper trough quickly dives into southern Plains and near the Gulf of Mexico on Monday and gets a secondary push on Tuesday. For Wednesday through Friday the upper ridge will be over the west and the large upper trough will be over the central and eastern U.S. The cold front will continue moving through Arkansas Sunday night and Monday with showers and thunderstorms. Increased instability is expected in the northwest Sunday evening. Northwest Arkansas is under a Marginal Risk of severe weather Sunday evening with hail being the main threat at this time. Cool, dry air will move in behind the front. Another front will move through the state Wednesday night and Thursday with a shot of reinforcing cool air. This could bring lows of mid to upper 40s to a large part of Arkansas. Below normal temperatures are expected through the period. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...COOPER
