Area forecast discussion, May 25, 6:36 PM CDT, 3 hours 5 minutes before
Area Forecast Discussion National Weather Service Little Rock AR 636 PM CDT Tue May 25 2021 .AVIATION... Upper level disturbance continues to move across the region. This impulse combined with daytime heating is producing scattered convection that will impact primarily the northern terminals through 06Z. Only widely scattered precipitation is expected through the remainder of the period but low clouds will likely impact the majority of the terminals around daybreak. VFR to MVFR conditions this evening will becoming IFR and then rebound to VFR by late Wednesday morning. && .PREV DISCUSSION...(ISSUED 249 PM CDT Tue May 25 2021) Short Term and Extended... Southwesterly flow aloft continues across the area, with embedded shortwaves producing areas of precipitation, with brief periods of dry weather between systems. At the surface, a cold front will be pushing into the area late Thursday afternoon into Friday, which will result in significantly higher rain chances. There may be some chances for severe weather across the area Thursday night as the front pushes into an area of instability. There have been a number of inquiries about the upcoming 3-day holiday weekend. High temperatures on Saturday and Sunday look to be quite pleasant in the wake of the cold front, with highs in the 70's in most areas. A bit of a ridge will start to build by Monday, and temperatures will warm up well into the 80's. As far as rain chances are concerned, there may be a few showers and thunderstorms across the southern and western half of the state on Saturday, but Sunday and Monday should be dry. The pattern aloft will become southwesterly again by early in the week, and rain chances will return by Tuesday. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...56
