NWS Forecaster Discussion
122 fxus63 kpah 070752 afdpah Area forecast discussion National Weather Service Paducah Kentucky 252 am CDT sun Sep 7 2008 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... anticipated scattered-broken low VFR deck coming in on a little upper wave energy has reached cgi and is imminent upon remainder of taf sites in next couple hours. Temporary breaks may allow for some fog development...likely most restrictive to visibilities at cgi. The aforementioned deck could/should scatter out tomorrow especially PM hours in light westerly-northwesterly flow regime as causative wave moves downstream. && Pah watches/warnings/advisories... Kentucky...none. MO...none. Illinois...none. In...none. && $$
