Large Gradient for November

02 Dec 2011 05:59 AM
Precipitation totals for November ranged from around double of average over southeast Iowa to around 10% of average over northwest Iowa as shown by the featured map. This pattern did not help the dry conditions that have been worsening over portions of the northern plains. A winter storm is set to arrive this weekend with a dry work week expected after that.
