I hereby allocate the next 2 hours to an open discussion about whether or not Tim only posts good or bad maps and whether he's a consummate truth teller or whether it is low key trolling. This forum to resume at 7:30 for the 00z GFS.
*hits gavel*
The weekly drought map shows no dramatic changes. But more and more, little by little, the upper regions of our biggest rivers are showing very dry or some drought. The Mississippi, Snake, Missouri, Colorado, and Rio Grande are all, at least, very dry. Your'e right Andie. Not looking good for a hot summer ahead. The Ohio, Tennessee, and other larger rivers of the Southeast are currently free of dry conditions. But these rivers lack a snow pack source and will be subject to rapid drying as the summer heat comes on. The Sacramento and west coast rivers are ok..backed up by good snowpack.
I'm actually curious to know if there is evidence for lower groundwater supplies in western WA/OR after a water year with 80-90% of normal precipitation vs. one with 110-120% of normal. I've always assumed that the groundwater supply fully recharges in winter.
Completely different story east of the Cascades, obviously.
