Prelim analysis. 2019 precipitation was extremely anomalous over parts of the Central/Northern Plains. Areas in #NEwx and #SDwx had at least 20-inches more annual precipitation than prior annual maxes over past 50 years. This is a +5 sigma standardized anomaly! #HappyNewYear pic.twitter.com/YK0h7b517O
