Area forecast discussion 
National Weather Service State College PA 
239 am EDT Sat Oct 11 2008 


Synopsis... 
high pressure will continue to control the weather through next 
Tuesday...resulting in warm sunny days and cool nights. A cold 
front will move across the area late Tuesday into Wednesday. Weak high 
pressure with slightly cooler temperatures will build into the 
area on Thursday. 


&& 


Near term /until 11 am this morning/... 
skies will be clear through late morning...with the exception of 
patchy River Valley fog through 930 am. 


&& 


Short term /11 am this morning through 6 PM Sunday/... 
plenty of sunshine will prevail later today...with above normal 
temperatures...as high pressure remains across the region. 


&& 


Long term /Sunday night through Friday/... 
plenty of sunshine will prevail into Tuesday...as a large 
ridge of high pressure surface and aloft remains across the 
eastern states. Heights will approach 594. Some patchy river 
fog possible. There will be a large range in min and maximum temperatures... 
as dewpoints remain fairly low...and winds will not be that 
strong. 


Some showers possible late Tuesday into Wednesday...as a front 
moves across the region. Heights stay above 570...so not 
looking at anything real cold. The real cold and stormy 
weather will stay across the western states. 


Models hint at heights falling off later in the week...with 
a weak low moving across or just to the south of the area on 
Friday. Thus went with chance probability of precipitation for Friday...gmos probability of precipitation. Went 
with gmos or near gmos temperatures for Friday. 


&& 


Aviation /07z Saturday through Wednesday/... 
blyr has dried out considerably over the last 24hrs with surface dewpoints 
running around 10f lower. Thus...believe fog will not be as 
widespread as yesterday morning and will not include it at any 
terminal sites early today. However...some uncertainty here...and can/T 
rule out a period of fog between 09-13z...mainly at bfd and ipt where 
conditions climatology suggests a 30 to 40 percent chance of MVFR or lower 
visibilities around dawn. 


Extended period of mainly VFR flying conditions and light/variable 
winds will continue into early next week courtesy of high 
pressure. Areas of radiational fog will form again in the Deep 
River/stream valleys of the alleghenies Sunday morning. 


A cold front is forecast to push into the region late Tuesday/early 
Wednesday...potentially accompanied by reduced cigs/vsbys. 


&& 


Ctp watches/warnings/advisories... 
none.
