000 FXUS64 KMRX 210140 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 940 PM EDT Tue Jun 20 2017 .DISCUSSION... Latest IR imagery shows fairly extensive cirrus shield extending NE out of the Gulf Of Mexico and across the Tennessee Valley this evening as Tropical Storm Cindy sits in the Northern Gulf. With forecast for a northward drift expected overnight, do not expect to see any end to cirrus ceilings area wide. Updated forecast to reflect increased cloudiness through tonight. Additionally, decreased POP`s in SW NC for remainder of the night as radar echoes are beginning to weaken S of the area and any pcpn looks to remain S of the area through the overnight hours, in agreement with latest HiRes HRRR and RAP13. Tweaked temperatures/dew points slightly in order to bring in line with latest observations. Dew points have dropped into the upper 50s and lower 60s across much of the area, helping to make it feel a little cooler and drier on this Summer Solstice...which occurs at 12:24 AM tonight. && .PRELIMINARY POINT TEMPS/POPS...
