Area Forecast Discussion National Weather Service Little Rock AR 556 PM CST Sun Dec 29 2024 ...New AVIATION... .SHORT TERM... (This evening through Tuesday) Issued at 219 PM CST Sun Dec 29 2024 Dry conditions are expected during this forecast period. KLZK radar returns indicate some mid level returns (~10kft), moving quickly east across northern sections of the forecast area. Satellite imagery indicates MVFR ceilings remaining over southern sections of the forecast area, continuing to diminish in areal coverage. On Monday, With clear conditions, and a compressional component to boundary layer flow, well above normal afternoon temperatures are expected. A cold front will quickly move southeast across the forecast area late Monday night and early Tuesday. Near normal temperatures are expected Tuesday. No precipitation is expected to be associated with this feature. && .LONG TERM... (Tuesday Night through next Sunday) Issued at 219 PM CST Sun Dec 29 2024 Behind Monday Night's strong cold front, high pressure associated with the coldest center of a Continental Polar (cP) airmass will move across Arkansas. Despite the really cold sounding name, a cP airmass is the most common to build in behind any decent cold front moving across the central United States during the winter months, and this airmass, being typical for this time of year, will bring us quite typical temperatures. Under high pressure, skies are expected to be mostly clear through the remainder of the work week with highs topping out in the lower to mid 50s in central and southern portions of the state, and holding up in the lower to mid 40s in the north. Overnight lows will get close to the freezing mark each night across central Arkansas while temperatures generally remain above freezing south and below freezing in the north. No significant precipitation is expected behind the front, but there is a tiny chance for a rain shower across southeastern Arkansas Thursday evening as winds briefly come around to the south as high pressure moves east of the state. Most rain is likely to remain south of the state across Louisiana, but have a 20 percent chance of rain for a few hours Thursday evening just in case some isolated rain showers sneak north of the state line. Another weak and dry front is expected to push across the state on Friday, reinforcing dry air across the state. As we head into the upcoming weekend a storm system just off the coast of Japan will make its way over the northwestern United States and drop southeast towards the central and south Plains. This storm system will spread surface cyclogenesis to the lee of the Rockies beginning Saturday which will have the effect of bringing northerly winds across the state around to the south with an increase in upper level cloud cover. Southerly winds are expected to bring some Gulf moisture up over the cool airmass over the state bringing an increase in rain chances due to elevated warm and humid air advection aloft early Sunday morning, expanding in intensity and coverage during the day on Sunday as large scale forcing for ascent associated with the Japan upper level trough spreads over the state. Behind Sunday's storm system is when the forecast becomes less consistent. The operational/deterministic 12Z GFS and ECMWF both bring in a follow up upper level that brings in a Continental Arctic (cA) airmass across the central and eastern United States beginning Sunday night into the following work week. These deterministic models do appear to be on the colder side of ensemble guidance so confidence in this verifying is not all that high at this time, but cooler than normal temperatures are quite likely during this time. If a true cA airmass moves in place, temperatures could potentially be well below normal, otherwise temperatures may simply sit just a few degrees below normal. Certainly something we'll need to keep a close eye on throughout the week. As it stands right now, as the rainfall comes to an end across Arkansas late on Sunday, there is a decent chance of a brief change over from rain to snow before precipitation ends. This change over seems to occur as dry air moves in aloft, so no accumulation is expected, if the changeover occurs at all of course. && .AVIATION... (00Z TAFS) Issued at 547 PM CST Sun Dec 29 2024 VFR conds are expected to give way to IFR/LIFR conds overnight across all but Nrn sites. Thinking dense FG and low stratus will develop between 08z-16z. Conds should improve beyond 16z on Mon as SW winds become gusty between 15 and 25 kts. Skies should clear from SW to NE through the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
