Complaints About Nighttime Cold Bias Over Snow

• Indianapolis SOO John Kwiatkowski said,”Lately we have noticed a very severe cold bias in the MESO ETA surface temps around here. A similar problem has also appeared in the MAV, but is not so pronounced. Since the problem seems to have developed about the same time we picked up a snow field in the Great Lakes area (although we never had more than a few tenths in our CWA, and most of that is gone), there has been speculation we have a snow initialization problem.”
