NWS Forecaster Discussion
168 fxus64 kmrx 181859 afdmrx Area forecast discussion National Weather Service Morristown Tennessee 259 PM EDT Friday Jul 18 2008 Short term (tonight and saturday)... there will be little change in the overall pattern in the next 24 hours...so will basically follow persistence. MOS guidance indicates some fog around the area tonight...however the model dewpoints are running too high this afternoon...so their depiction of fog may be overdone as well. A strong midlevel capping inversion will again prevent deep convection from developing tomorrow afternoon. 850 mb temperatures and 1000-850 mb thickness increase tomorrow...so expect highs a few degrees higher than today. But MOS has been running a bit warm...so leaned toward the slightly cooler met guidance. Long term...(saturday night through friday)... high pressure ridge at the surface and aloft continues Saturday night and weak low pressure off the coast of the Carolinas will be far enough away for dry conditions across the forecast area Saturday night. Sunday Ridge starts to shift southwest and weak shortwave energy moves into Tennessee Valley from the northwest ahead of surface low and nearly stationary cold front moving across the southern Great Lakes. Heating and instability enough to set off isolated showers and thunderstorms during the middle afternoon to early evening. Monday there should be a better chance all day as front moves into Ohio Valley and shortwave energy spreads out ahead of front. For the rest of the week models generally keep front across or just south of forecast area so have chance showers and thunderstorms through Friday. GFS keeps ridge stronger over forecast area Monday and Tuesday and front farther north but European model (ecmwf) brings short wave energy and front into Tennessee by Tuesday with drier air across the NE section briefly Wednesday. Followed the preffered European model (ecmwf). Temperatures will be near 90 to lower 90s Sunday through Tuesday and then cooler with more clouds and rain chances as upper trough moves into NE part of the country. && Preliminary point temps/pops...
