NWS Little Rock, AR wrote its last area forecast discussion before the first event at Feb 29, 11:28 PM CST, 32 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 1128 PM CST Sat Feb 29 2020 AVIATION... VFR conditions are expected through much of the period, though some mvfr stratocu will develop in the north by the afternoon Sunday. Expect scattered showers 18-00Z. Showers will become predominate at all TAF sites after 00Z. PREV DISCUSSION...(ISSUED 235 PM CST Sat Feb 29 2020) SHORT TERM...Tonight Through Monday Satellite imagery was showing high clouds beginning to overspread Arkansas from the west as a shortwave ridge was exiting to the east. High, and then mid, clouds will increase over the state overnight tonight as the flow aloft becomes more quasi-zonal. Lows tonight will range from the lower 40s over the northeast portion of the forecast area to near 50 over much of the southern half of the region. For Sunday, a shortwave trough will approach Arkansas from the west amidst the flow aloft with low and mid level moisture increasing rather rapidly across the state from west to east. This will lead to the development of scattered showers across much of the region mainly during the afternoon hours. Afternoon highs will generally range from the upper 50s over the higher terrain of the north to near 70 over the far south. Precipitation chances will increase going into Sunday night as the shortwave trough progresses from west to east across the forecast area. Dynamics and instability associated with the trough will lead to isolated thunderstorms amidst widespread shower activity. Rainfall amounts will vary from around a tenth of an inch to upwards of a half inch. Sunday night lows will generally range from near 50 over the far north to near 60 over the far south. On Monday, a weak front will enter the far northwest corner of Arkansas as the shortwave trough aloft begins to exit the state to the east. Sufficient moisture and instability will remain across the region for scattered showers with more isolated thunderstorms expected through the day. Could see another tenth of an inch to a quarter of an inch of additional rainfall area-wide. Afternoon highs will range from the lower 60s over the northern higher terrain to the lower 70s over the far south. LONG TERM...Monday Night Through Saturday A powerful southern stream will undergo amplification early this period, as a closed upper low approaches from the west. An associated, slow moving cold front will approach early in the period, and together will act on abundant available moisture in the atmospheric column, as indicated by anomalously high forecast precipitable water values. Main concern during this period is defining any excessive rainfall potential during the first half of this period. At this time, various deterministic model runs are pointing towards the southern half of the forecast area as having the best chance for excessive rainfall. Most of the precipitation will affect areas to the east of the state by early Thursday. Dry conditions, and slightly above normal temperatures are expected for the end of the upcoming week. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...GOUDSWARD
