Area Forecast Discussion National Weather Service Little Rock AR 1240 AM CDT Sun Nov 1 2020 .AVIATION... VFR conditions are expected through Sunday evening. A cold front will move through the state overnight/Sunday morning. North to northwest winds at 10 to 20 mph are expected behind the front on Sunday, with some gusts from 25 to 30 mph. (46) && .PREV DISCUSSION...(ISSUED 240 PM CDT Sat Oct 31 2020) Short term...Tonight through Monday The latest surface analysis places surface high pressure to the south and east of the state and low pressure well to the north. The result was a splendid late October day with plenty of sunshine, light winds and very pleasant temperatures. It was a welcomed respite from the gloomy and unsettled conditions of late. A dry cold front will move across the state tonight. The front is lacking both moisture and dynamics and only a few clouds and a wind shift will mark its passage. Winds will come up briefly after fropa with another shot of cool and dry air in its wake. Trick or treaters will not have to worry about any precipitation but it may be a bit chilly for the youngsters as we progress through the evening. High pressure, both on the surface and aloft will then build over the region Sunday afternoon and evening. Winds will subside and clear skies will set the stage for some chilly temperatures by Monday morning. Freezing temperatures will be possible across the north and the situation will need to be monitored for possible headlines. Temperatures will average below normal through the period with the cold frontal passage and the high building in. Highs will be in the 50s and lower 60s. Long term...Monday Night through Saturday NW flow aloft will become more Werly as zonal flow returns throughout the CONUS over the first half of next week. Surface high pressure will shift eastward during this time as well, with southerly flow warming temperatures to slightly above average by next Friday. An upper SWT will move through the SW CONUS, approaching the central/southern Plains regions by mid week. High pressure over the eastern CONUS/western N Atlantic will slow the progression of this trough and it will move slowly through the central/southern Plains regions mid-late week. A surface low will develop over the same region. The upper trough will eventually shift to the SE by the weekend. By that time, upper level high pressure will be building into the southern Plains from the S/SW CONUS but surface high pressure in the forecast area will be weakened. && .LZK Watches/Warnings/Advisories...NONE. &&
