Short term...(tonight through friday)...current surface analysis 
indicate clear skies across the forecast area as the ridge 
dominates the weather. It will continue to move east but will 
dominate the weather across the region through midday Friday. 
Skies will be clear tonight and the min temperatures will drop below 
freezing in most places away from the lake. Will have areas of 
frost across the area for early Friday morning. The high will move 
east of the region Friday as a warm front approaches the forecast 
area from the west. The clouds will increase west to east Friday 
afternoon as it approaches and low probability of precipitation in southern Cass by late 
afternoon. 


Long term [friday night - wednesday]... 


High pressure over eastern Canada and the eastern United States will 
help to keep the Northland dry early this weekend...but there will 
be increasing chances of showers and storms from the west due to low 
pressure in the plains. Temperatures should be slightly below normal 
early this week...but there will be a warming trend next week. The 
middle to late week period could be rather active for thunderstorms 
across or near the Northland. The GFS/Gem/ECMWF suggest one or two 
warm fronts lifting through or near the Northland middle to late next 
week...which could be the focus for thunderstorms. The second warm 
front indicated by the GFS and European model (ecmwf) for later in the week could be 
the more active front. It is too early to have any clear idea on the 
potential for severe weather...but this second warm front may be the 
most likely opportunity of the week for the Northland at seeing any 
severe weather.
