Area forecast discussion 
National Weather Service Green Bay WI 
344 PM CDT Sat Mar 20 2010 


Short term...today through Sunday 
of interest this afternoon...a few echoes appeared on radar along 
the Menominee Shawano County line. These returns are associated 
with prescribed burn of in this region and should diminish early 
this evening. 


Otherwise...tranquil pattern noted through Sunday. Some high 
clouds will stream across the southeast portion of the forecast 
area for the remainder of the afternoon and early evening hours. 
Will have becoming mostly clear in this region with mostly clear 
skies over the remainder of the region. Will go below guidance in 
the typically colder locations. 


Cold front expected to move across southern Canada on Sunday. 
Winds will become south or southwesterly over much of the area. 
Better mixing will take place across the north due to tighter 
pressure gradient and higher terrain to mix deeper. Have trended 
toward the cooler met guidance in the Fox Valley and Lakeshore 
region where poorer mixing will occur or lake breeze will kick. 
Leaned toward the warmer mav guidance across central and north 
central Wisconsin due to better mixing. 


Long term...Sunday night through Saturday. Like much of the 
winter season...all the action is staying to our south. The 
current big system over the Southern Plains that is producing snow 
from North Texas to Chicago will move almost straight 
east...leaving zonal flow across the Great Lakes for the next few 
days. An upper trough swings through Tuesday and Tuesday night 
that might bring some rain or snow showers. Then dry northwest 
upper flow through Thursday. An upper trough moving from the 
Central Plains could bring snow or rain next Saturday but there 
are differences in the models as to the track of the system.

Aviation...VFR conditions expected tonight and Sunday with no 
significant storms in sight. Northeast or north winds will become 
light and variable early this evening...then become west southwest 
Sunday morning.
