Discussion...Areas/spots of flash flooding remain possible currently. 00Z radar mosaic imagery depicts several areas of concentrated showers and thunderstorms in higher terrain north of Phoenix, AZ and across mainly rural areas of northwestern, central, and northeastern New Mexico. The convection was rotating around a weak upper low centered near the AZ/NM border. The combination of this low, orographic lift, and modest surface heating/instability continues to support a few areas of 0.5-1.0 inch/hr rain rates. Meanwhile, locally sensitive areas/burn scars across the discussion area (especially in New Mexico) continue to pose flash flood potential given the aforementioned scenario.=20 Near sensitive areas, only little rainfall is needed to cause issues with excessive runoff. Flash flood potential should continue through 04Z or so. Models depict a gradual decrease in instability/rainfall rates over time in concert with a loss of surface heating. Flash flood potential should begin to lessen - especially after sunset.
