Area Forecast Discussion National Weather Service Little Rock AR 557 AM CST Mon Dec 30 2024 ...New AVIATION... .SHORT TERM... (Today through Tuesday Night) Issued at 411 AM CST Mon Dec 30 2024 Areas of low clouds/dense fog have contd to slowly expand over central and southern AR overnight. Based on obs trends, added a few more counties to the ongoing Dense Fog Advisory. Still appears that north AR wl avoid the lowest vsbys this mrng. On the mrng wx map, sfc low pressure was centered over far western KS. This sys is progged to race to the east thru tngt, thanks to a progressive quasi-zonal flow pattern in place. As a result, south/ southwest winds wl incrs later today acrs the FA, allowing the fog and low clouds to eventually dissipate. This wl allow aftn highs to top out in the upper 50s to the upper 60s. The aforementioned sfc low will pass to the north of AR late today and tngt. The main axis of lift/moisture is expected to stay north of the FA as well, although some patchy light rain/drizzle may occur over far northern AR. Opted to keep PoPs below thresholds (<20%) due to low confidence attm. An assocd CDFNT wl sweep thru the state tngt, with winds shifting to the west and northwest. Cooler and drier air will follow the FROPA, bringing temps down closer to normal for late Dec. Highs Tue aftn wl range fm the mid 40s to the mid 50s. Lows Tue ngt are expected to fall into the mid 20s to the mid 30s. && .LONG TERM... (Wednesday through Sunday) Issued at 411 AM CST Mon Dec 30 2024 Guidance continues to support dry conditions through Friday as the area of surface high pressure that moved into the region behind Monday's strong cold front remains dominate. The upper flow will be from the west to northwest through Friday with air of Pacific origin over the region. This set up will support temperatures very close to climatological averages with highs in the mid 40s to mid 50s. Lows will be close to the freezing mark each morning across central Arkansas with readings generally remaining above freezing south and below freezing in the north. As the aforementioned area of high pressure. Guidance also remains consistent in drying a dry cold front through the region on Friday with slides off to the east, winds will briefly turn to the south resulting in just a slight chance of showers Thursday evening along the Arkansas/Louisiana border. Guidance also remains consistent in driving another cold front through the region on Friday. This boundary will not produce any precipitation but will provide a reinforcing shot of slightly cooler and drier air to the state. Meanwhile, an upper trough will be making its way into the Pacific NW by Saturday morning. Lee side surface cyclogenesis is expected in response with a noticeable increase in moisture. As the atmosphere moistens up, precipitation chances will increase in the developing warm air advection pattern. Saturday does appear dry at this point but as the system passes through Sunday, widespread precipitation chances return for late Saturday night and Sunday. It appears at this time that temperatures will be slowly rising Saturday night and into Sunday with most guidance now indicating just liquid precipitation. Can not rule out some brief winter weather over the far NE corner of the CWA but any accumulation will be minimal, if there is any at all. ECMWF has really warmed up versus the past few runs and is now in good agreement with its GFS counterpart. Precipitation appears to wrap up before another shot of cooler air arrives and another brief changeover to some winter weather can not be excluded over the north with little if any impacts. && .AVIATION... (12Z TAFS) Issued at 550 AM CST Mon Dec 30 2024 Widespread low clouds/dense fog will persist acrs central and southern AR thru the mid mrng hrs, resulting in contd IFR/LIFR conds. A few locations wl see brief VLIFR conds early as well. South/southwest winds wl incrs later this mrng, allowing VFR conds to return. A CDFNT wl move acrs the FA tngt, with winds shifting to the SW, then WNW late. North AR wl see VFR conds thru much of the PD, with some MVFR ceilings returning late in the PD. && .LZK WATCHES/WARNINGS/ADVISORIES...
