Amazing storm over northern Colman County at least when looking at the max updraft fields. Saw a rapid increase of max updraft going from around 15 at 2250 to 29 at 2300. MESH increased to less than .75 inch at 2250 to over 2 inches at 2300…with max div abv 8km above 23. Needless to say we warned — just looking for reports now. MRD/TT
