NWS Little Rock, AR wrote its last area forecast discussion before the first event at Mar 31, 11:37 PM CST, 23 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 1237 AM CDT Wed Apr 1 2020 .AVIATION...01/06Z TAF CYCLE VFR conds wl prevail thru the PD. Cannot rule out some patchy fog toward daybreak this mnrg, with TEMPO groups included for MVFR vsbys. High lvl clouds wl incrs later today and tngt. /44/ && .PREV DISCUSSION...(ISSUED 233 PM CDT Tue Mar 31 2020) SHORT TERM...Today Through Thursday Night Northerly winds will continue to carry cooler air into the state through Wednesday morning, cooling the low temperature tomorrow morning to the lower to mid 40s. Upper level subsidence and surface high pressure will push east/northeastward through Arkansas tonight through Thursday. Surface wind will shift to come from the south, warming the Wednesday high to the upper 60s and lower 70s. Clearer skies Wednesday night will allow temperatures Thursday morning to cool to the upper 40s. Persistent southerly flow will warm temperatures Thursday afternoon to the upper 60s and lower 70s. By late Thursday, a 500mb trough will move into the western CONUS as a surface low pressure system approaches Arkansas from the west. Rain and isolated thunderstorm chances will increase by Thursday afternoon for the western part of the state. LONG TERM...Thursday Night Through Tuesday Models continue to advertise an overall progressive pattern with the synoptic scale features in generally good agreement. There are some timing differences with the individual features so a blend of model solutions is preferred this afternoon. Pattern initiates with deep troughing over the western united states and subsequent downstream ridging over the Ohio Valley. In between these two features will be a cold front extending from west Texas and through the central plains. Moisture will be on the increase in advance of the boundary which will be moving slowly as it runs into the aforementioned upper ridge. As such, precipitation chances return until the front pushes through early Saturday. A much stronger trough/upper low will be located off the central coast of California by late in the weekend with a low amplitude ridge over the mid south. Several impulses embedded in the prevailing flow will bring rounds of precipitation to the area. This is where the timing and location differences come into play with the solutions not in the best agreement. Rainfall amounts do not appear to be overly excessive at this point but there will be at least a chance of precipitation everyday through the period. Severe weather parameters do not really come together with the best chances seemingly just after the period concludes. Concerning temperatures, with the exception of Saturday, highs look to average above normal for early April. Lows look to average real close to where they should be for this time of year. && .LZK Watches/Warnings/Advisories...NONE. &&
