Drought forges ahead


http://ticker.mesonet.org/archive/20200709/20200707_OK_trd.png

Shrugging off recent rainfall, flash drought surged to the east this week, now 
covering much of northeast Oklahoma. There were some improvements in the drought
picture across the western Panhandle, but the rain still had benefits elsewhere, 
mainly by stopping further development and intensification.

So that's some good news. And even better news...rain is falling RIGHT NOW across
those newly hatched areas of drought in northeastern OK.

Big deficits remain across much of the northwestern half of the state when you
look at the long term picture, with more significant deficits showing up across
the far northeast as we look at the flash drought's spread. Check out the 
different areas that pop out on the 30 day maps vs the 90 day maps. 

30 days

The deficits across the Panhandle go back to last fall, and the damage from
that longer term drought is evident in these pictures sent to us from a rancher
near Kenton in western Cimarron County. It's very plain to see the difference
in fortunes from times of plenty vs what we see out there this year...basically
the surface of the moon. Same location in both pics.

With that death dome of high pressure moving back over the state from the west,
I'm afraid the drought will worsen once again across western Oklahoma before
we see more improvements. Highs in the 100s with strong winds will make short 
work of that moisture that fell, and the prospects for rain are going to be 
nil for awhile.

I don't think I need to mention the heat again. 

But what sort of sadist would I be if I didn't? HERE COMES THE HEAT, courtesy
of the death dome! Two droughts enter, three droughts leave.

The heat starts today. The burned up moose out front should have told ya.

Summer in Oklahoma. Woe be to those years where we enter with drought already in 
place.
