Area forecast discussion 
National Weather Service Lake Charles la 
314 am CDT Sat Oct 11 2008 


Discussion...patchy fog continued to develop across the region 
due as radiational cooling and light to calm winds prevailed. Thin patchy 
areas of fog will burn off this morning. Expect redevelopment 
Saturday night into Sunday morning basically under the same 
conditions. 


Looking at the bigger landscape...upper level high pressure with 
surface ridging across the region will continue to provide 
excellent outdoor weather today and Sunday. An upper level storm 
system across the western United States will push into the Central 
Plains Sunday night into Monday. This system will not have major 
impact through Monday as high pressure in the upper levels holds firmly 
in place. 


Meanwhile...the GFS model shows an upper level inverted trough 
moving westward along the northern Gulf Coast from Florida on 
Sunday into Louisiana by Monday morning. This disturbance may 
bring isolated to scattered showers on Monday. 


A weak front will push into the region on Wednesday reinforcing a 
east to northerly flow that will be already in place at that time. The 
front will wash out north of the coastline on Thursday. Scattered showers 
and thunderstorms will be possible as the front stalls and washes 
out Wednesday and Thursday. High pressure will settle back in next Friday 
just in time for the weekend. 


&& 


Aviation...patchy fog early this morning will burn off shortly 
after sunrise. Brief MVFR conditions is possible in the patchy fog 
areas...otherwise VFR conditions to prevail. Patchy fog will 
redevelop later Saturday night into Sunday morning basically 
repeating the same pattern. 


&& 


Marine...high pressure will continue to hold over the northwest 
Gulf today with generally tame seas and southerly winds. Sunday 
will bring slight higher seas and winds as southerly flow 
increases in response to low pressure developing across Colorado 
and Oklahoma.
