066 FXUS64 KLZK 232322 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 522 PM CST Sat Nov 23 2024 ...New AVIATION... .SHORT TERM... (This evening through Monday) Issued at 216 PM CST Sat Nov 23 2024 Latest satellite imagery indicates scattered cirrus across the state this afternoon. Surface observations indicate temperatures again above normal for late November. A high pressure axis analyzed from eastern Texas to to eastern Iowa will move eastward early in this period. The resulting southerly low flow will promote warmer, and well above normal temperatures for Sunday. On Monday, a cold front will approach from the northwest. Forecast soundings suggest limited moisture and instability will be available when the front approaches, which should limit overall convective potential. && .LONG TERM... (Monday Night through next Saturday) Issued at 216 PM CST Sat Nov 23 2024 Not a lot of value added changes have been made to the forecast as the latest guidance has not really waivered that much from previous solutions. Overall a rather progressive pattern is expected with some chances of precipitation, mainly centered on Thanksgiving day. Period initiates with upper low traversing the US/Canadian border. Associated frontal boundary and its associated wind shift will be clearing the far SE corner of the CWA. Any lingering precipitation with this boundary will quick exit off to the east. Cooler air will follow this boundary but temperatures will still be approaching seasonal averages. Surface high pressure will provide a dry Tuesday but will quickly move off to the east by late Wednesday as yet another shortwave approaches in the broad cyclonic flow. Guidance indicates surface low pressure developing over central Oklahoma and moving off to the NE through the holiday, latched on to another frontal boundary. Rain chances over the north can not be discounted late Wednesday but the best chances of precipitation appear to be Wednesday night through midday Thursday with widespread showers expected. Pattern is not very favorable for thunderstorms but a few rumbles of thunder can never be ruled out. Pattern does also not appear to be favorable for any type of winter weather but it would not be surprising if a few flakes of snow are observed early Thanksgiving morning. Rainfall amounts will not be excessive with most areas seeing a quarter of an inch of rain or less. The remainder of the period does appear to be dry but a developing ridge along the west coast will result in a pronounced NW aloft over the region. Temperatures will actually drop to below average levels from Thanksgiving and beyond with surface high pressure largely dominating although some subtle shortwave features are still seen. && .AVIATION... (00Z TAFS) Issued at 519 PM CST Sat Nov 23 2024 VFR conds are expected through period however mid/high clouds will increase in coverage through the day on Sun. Wind shear is anticipated at Wrn and Nrn sites overnight, which should diminish during the day on Sun once surface winds and gusts increase. SW winds may gust up to 15-25 kts on Sun afternoon ahead of an approaching cold front. && .PRELIMINARY POINT TEMPS/POPS...
