PORTIONS OF SD AND FAR SOUTHWEST MN THIS MORNING.
DISCUSSION...AN AREA OF MODERATE TO LOCALLY HEAVY SNOWFALL HAS
REMAIN FOCUSED ACROSS CENTRAL PORTIONS OF NEB AND SD...ASSOCIATED
WITH A PRONOUNCED SHORTWAVE IMPULSE OVER THE CENTRAL PLAINS. A
GRADUAL INCREASE IN SNOWFALL RATES IS FORECAST TO OCCUR THROUGH
MID-LATE MORNING AS THE PRIMARY SURFACE LOW /OBSERVED NEAR ST.
JOSEPH MO AS OF 08Z/ CONTINUES TO DEEPEN AND MATURE WHILE SHIFTING

AS THE SURFACE FREEZING LINE SHIFTS EASTWARD...A CHANGEOVER TO SNOW
SHOULD OCCUR ACROSS SOUTHWESTERN MN AND WILL CORRESPOND WITH AN
INCREASE IN PRECIPITATION RATES...ESPECIALLY AFTER 12Z.
Schools being cancelled as the snow starts to ramp up now.
This storm was supposed to be over Minneapolis. Look where it is right now... a bit south more now. That should change the heavy snow forecast areas by at least 25 miles.
998mb Storm. Tightening Isobars over MN & SD (WIND!)

Good for me. The farther south it goes, the cooler it'll get here.
I'll call this "The Purple Band" without getting technical.
Thing of beauty on the map and special to be under. HEAVY snows under that band which usually doesn't shift too far off. Should stay within my outline.
Snowfall reports starting to come in as the sun comes up there now
The Blizzard, She is here. Not quite light enough to take any pictures. Will take a couple short videos "from the windows" shortly and upload them. Provided we keep Internet connection,through the storm.
By Saturday sunrise its over and done in Minnesota. Snow starts in Michigan and Ohio Saturday afternoon
