NWS Forecaster Discussion
664 fxus63 kpah 071111 aaa afdpah Area forecast discussion National Weather Service Paducah Kentucky 615 am CDT sun Sep 7 2008 Update for 12z aviation... Discussion... weak high pressure should keep conditions essentially dry today through Monday. The scattered light showers moving along the Interstate 64 corridor will continue off to the east. Broad long wave trough over the Continental U.S. Will likely result in clouds from time to time across the forecast area. Monday evening a cold front should be just northwest of the area. It is forecast to push south across the region Monday night into into Tuesday...so will continue with our low chance probability of precipitation for showers and perhaps a few thunderstorms. Dry middle week weather will be replaced by unsettled conditions late in the week as high pressure over the NE U.S. Moves away and return flow sets up. && Aviation... brief LIFR visibility and ceiling at kcgi early this morning. Otherwise around 15z VFR ceilings and visibility at all sites. Winds will be relatively light with a northerly component. Overnight tonight bring fog back into all sites after 06z Monday with MVFR visibility possible at kcgi. && Pah watches/warnings/advisories... Kentucky...none. MO...none. Illinois...none. In...none. && $$
