Southern corn leaf blight has been sporadic in AL this year. The disease is caused by the fungus Bipolaris maydis. Lesions are tan, somewhat rectangular & have reddish-brown margins. Resistant hybrids & foliar fungicides are available for control of SCLB #CPN #PlantDisease #Corn

Hey, we're shocked too! 7-9 inches own in SE OK, and a good dose for all but NW OK. We'd kill for that hair, though. #okwx #okmesonet

Oh no, a dreaded *CLICK FOR EMBIGGENATION* day! 2 rounds of storms, the first (and less likely) will be this afternoon and evening along the dryline. Scattered strong supercells may form and have a substantial risk of all severe hazards. ticker.mesonet.org #okwx #okmesonet

Could we see 100s in the Panhandle this weekend? I mean, it ain't out of the question. Might as well have summer a week after our visit from winter. Oklahoma doing Oklahoma stuff! ticker.mesonet.org #okwx #okmesonet

After nearly 6 years, Oklahoma is drought-free again! The last time: July 23, 2019. Don't worry about the yellow, that's D0, showing areas going OUT of drought. It's not a drought category. Lots more rain on the way! ticker.mesonet.org #okwx #okmesonet
