Area forecast discussion 
National Weather Service Grand Forks ND 
940 am CST Thursday Dec 4 2008 


Discussion... 
forecast challenge for update will be cloud trends...temperatures 
and snow potential. 


Fairly broad band of low level relative humidity/MVFR ceilings in wake of passing middle 
level shear axis will swing through forecast area today. This in addition to 
low convective temperatures in the middle teens with cold pool overhead 
should result in plenty of cloud cover. Upstream Canadian metars 
indicating -sn however visibilities for the most part >6 miles so will 
maintain mainly flurry mention. Even with lack of snow 
cover...eventual clouds will limit any temperature recovery and 
temperatures at best will reach convective temperatures in the middle 
teens. Will make some minor adjustments to cloud trends otherwise 
current forecast in good shape. 
&& 


Aviation...expect MVFR ceilings to overspread forecast area from northwest to southeast mainly 
during afternoon hours. Could see some -sn however visibility not expected 
to drop below VFR range.

Fgf watches/warnings/advisories... 
ND...none. 
Minnesota...none.
