000 FXUS64 KMRX 210335 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1035 PM EST Tue Feb 20 2018 .DISCUSSION... Latest radar indicating shower activity over northern Alabama and Georgia that is struggling to hold together as it reaches the Tennessee border. Latest high resolution models indicating that some light shower activity will start to make it into Southeast TN by midnight and push northward overnight. However, coverage is expected to remain fairly isolated throughout the overnight hours. Temperatures have remained a little higher than previously forecasted in the grids, so did tweak those upward a bit, although 0Z MOS continues to support current overnight lows, so did not adjust those at this time. With very uncharacteristic warmth, expect all three airports to match or beat their record high low temperatures by morning. && .PRELIMINARY POINT TEMPS/POPS...
