Looking further at HGR as to anomalous totals here are the 10 driest years in recorded history for HGR or the HGR area. If you take the current total of 16.6 and divide it by 254 (number of days already passed) you get an average of .065" per day over the year so far. Taking the .065 x 111 days left and add that total to the current total, you would end up 23.82" for the year or the second driest year since 1899. Only one year of the top 10 years, 2001, is anywhere near these records in recent times. The next most recent year in the top 10 is 1965. It is not as simple as this, but the rest of this year features normally drier months, so it is a legit discussion point. Using HGR because MDT totals do not reflect the greater level of drought along the southern tier.
