A quick review of HW has the drought effecting
New England (local farmland burnt dry by the summer sun)
Middle Atlantic States (particularly hard hit)
Southeast (over the dry winter and spring)
Great Lakes States (rainfall is at 50%)
South Central States (re watertables. the drought has not helped matters much)
Great Plains (The drought has rendered the grass on the plains tinder-dry)
The Western states
Southwest (Rainfall Unaffected loss of northern rivers make agriculture impossible) The state details contradict this.
Pacific Northwest (Increased Rainfall)
At the detail levels most states mention the drought.
California (rainfall down 10 inches. severely limit agriculture)
New Mexico (drought made conditions worse)
Arizona (Identical to new Mexico)
Nevada (Without water)
Montana (Drought made more dry)
Colorado (no direct mention)
Wyoming (the drought will cut short the development of shale resources)
Utah (effected by limited snow fall due to drought)
Ok two regions seem to have greater than 50% loss in precipitation (Great Lakes and Middle Atlantic states)
As you noted in the description of prior droughts this is unprecedented (The Texas drought gets a mention at 40%). California is also down 45%. Almost all other regions seem to suffer different but similar fates.
When you look at my national charts showing that the driest year ever had only a 17% reduction in the total. The HW drought is off the charts compared to 120 years of history.
I can accept that the war could cause weird weather, but IMO the HW drought is all encompassing to a degree that staggers the imagination when compared to historical data.
