640 FXUS64 KLZK 150855 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 255 AM CST Fri Nov 15 2024 ...New SHORT TERM, LONG TERM, AVIATION... .SHORT TERM... (Today through Saturday Night) Issued at 253 AM CST Fri Nov 15 2024 Surface observations and the satellite perspective confirm the quiet start to the day across the forecast area. Temperatures currently range from the mid 30s across the higher elevations to the mid 40s over the Delta under clear skies. T/TD depressions are small enough across parts of the state that a little patchy fog or even patchy frost remains possible and will not make any wholesale changes to the grids or the frost advisory this morning. Area will remain under the influence of high pressure both aloft and on the surface today and tonight before the axis of said ridge moves to the east Saturday. The ridge will be over the SE CONUS by the end of the period as a significant trough drops into the west. Upper pattern will buckle in response with southwest flow developing over the CWA with an uptick in moisture as a front moves into the nations midsection. The forecast will remain dry through the period but clouds will be on the increase late Saturday and into Saturday night as the next system approaches. Temperatures will warm into the 60s today and Saturday with lows tonight ranging from the upper 30s to mid 40s. Overnight lows Saturday night will be a little warmer as southwest flow increases. && .LONG TERM... (Sunday through Thursday) Issued at 253 AM CST Fri Nov 15 2024 SUNDAY/MONDAY: In the upper lvls, a H500 ridge will be positioned over the Southeastern region of the CONUS with southwesterly flow over Arkansas. A quickly ejecting trof out of the Desert Southwest region of the CONUS will rapidly make haste over the Southern Plains region of the CONUS. At the sfc, a low pressure center will be placed across southwestern Oklahoma with a stationary boundary extending eastward into the Mid-West region of the CONUS and a southward extending cold front that will be along the I-35 corridor in Texas. The combination of these two features at the upper lvls and sfc will equate to unsettled weather, but it will be a fast-moving system that impacts the state of Arkansas and CWA on Sunday into the day on Monday with mostly rain, but a thunderstorm or two is not out of the question; however, a severe weather outbreak is not anticipated. Temperatures over this two day period will be well-above normal for this time of the year with both low and high temperatures around 10 to 15 degrees above average for mid-November. TUESDAY/WEDNESDAY/THURSDAY: The upper lvl trof moves over the Great Lakes region of the CONUS with a well defined cyclone at the base of the trof, but slows considerably. At the sfc, a cold front completes the journey through Arkansas pushing rain east of the state. POP chances do exist over this period due to the close proximity of the upper lvl cyclone and near sfc trof, but does not look to be a considerable confident signal for widespread rainfall over Wednesday and Thursday. Tuesday looks to remain rain-free besides POPs across far eastern Arkansas as the cold front sweeps across the eastern flank of Arkansas and moves into Mississippi and Tennessee. Temperatures over this three day period will begin on Tuesday around 10 degrees above normal, but as a series of cold fronts sweep through the state on Tuesday and the airmass behind the front will funnel in temperatures that will be near average to below average by Thursday into the late week across Arkansas as a combination of northwesterly flow in the upper lvls will assist in this transitions of temperatures from near average to below average for mid-November. && .AVIATION... (06Z TAFS) Issued at 1127 PM CST Thu Nov 14 2024 High pressure both aloft and on the surface will bring widespread VFR conditions to the terminals through the period. Some patchy fog will be possible around sunrise for a few locations. Winds will generally be light with a NE component over eastern AR with more of a W to SW wind over the west, && .PRELIMINARY POINT TEMPS/POPS...
