FXUS64 KTSA 070133 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 833 PM CDT Sun Apr 6 2025 ...New UPDATE... .KEY MESSAGES... Updated at 155 PM CDT Sun Apr 6 2025 - Freeze expected across much of eastern Oklahoma and western Arkansas late tonight into Monday morning. - Another freeze possible Tuesday morning across northern areas. - Mostly dry week ahead. && .UPDATE... Issued at 832 PM CDT Sun Apr 6 2025 Upper trough axis is sliding across the forecast area this evening. Skies will clear from north to south as this occurs. Combine this with light and variable wind as weak surface ridge axis slides overhead and you get a favorable setup for good radiational cooling. High temps today were already nearly 20 degrees below average for this time of year, so with a good head start overnight lows will drop to near or below freezing over much of the forecast area by Monday morning. A Freeze Warning is in effect from 1 AM to 10 AM. Lacy && .SHORT TERM... (This afternoon into tonight) Issued at 155 PM CDT Sun Apr 6 2025 A few areas of light rain continue to linger across far northeast Oklahoma into northwest Arkansas early this afternoon as weakening mid-level shortwave pulls out of the region. This activity is expected to be out of the area by late afternoon. Clearing skies and light winds are on tap for the area later tonight as high pressure builds into the region.
