Area forecast discussion 
National Weather Service Green Bay WI 
255 PM CDT Friday Aug 29 2008 


Short term...tonight through Saturday...high and dry is the 
forecast through the period. Zonal flow will begin to amplify over 
the state this weekend. Made minor changes to previous 
forecast...dropping mins slightly...as low level flow weakens 
towards morning and dews in the 40s at this time. With drier air 
upstream continuing to filter in...and expected low level winds 
will stay away from mention of fog tonight. Lowered dew points for Sat. 


Long term...Saturday night through Friday 
large high pressure will remain in control of the weather 
Saturday night through Monday night. This period of should be 
dominated by clear nights and sunny days with warm afternoon 
temperatures and relatively low humidity with dew points in the 
50s. 


By Tuesday...southerly flow will finally bring somewhat higher 
dewpoints to the area with most locations in the upper 50s to 
middle 60s Tuesday afternoon as cold front approaches Wisconsin 
from the west. A cold front will bring a chance of showers and 
thunderstorms to the area...beginning across the west late 
Tuesday night and across the entire area on Wednesday. The 
front will then stall south of the area Wednesday and Thursday. 
Over running expected to set up with remants of tropical storm/ 
Hurricane Gustav are expected to move into Wisconsin on Thursday 
and Friday. This will be much needed rain as much of the north has 
fallen into the moderate drought category per latest drought 
monitor. 


Temperatures will be well above normal for most of the week. 
Temperatures could approach record levels in some spots and 
September 3rd and 4th.

Aviation...VFR conditions expected through the weekend. Do not 
expect fog tonight given some wind just above the ground as short 
wave passes to our north. Marginal low level wind shear possible 
around 06z tonight with light southwest winds at the surface and 
west winds of 20 to 25 knots between 1 and 1.5k above ground level. Given marginal 
nature...left out tafs at this time.

Grb watches/warnings/advisories...
