The core of the high will move east of the Northland tonight into Friday...and winds will become south to southeast for most areas. Middle to high clouds will increase late in the period. Previous discussion... /issued 308 PM CDT Thursday may 23 2013/ 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. && Point temps/pops... dlh 63 43 58 41 / 10 30 20 10 inl 70 44 64 43 / 10 30 20 0 brd 69 49 61 48 / 50 60 40 20 hyr 66 43 63 43 / 10 30 20 10 asx 57 41 61 40 / 0 10 10 0 && Dlh watches/warnings/advisories...
