The National Weather Service in Tulsa has issued a severe thunderstorm watch for several northeastern Oklahoma counties through 11 p.m. Sunday.
Counties included in the watch are Adair, Cherokee, Craig, Creek, Delaware, Haskell, Hughes, Kay, Latimer, Lincoln, McIntosh, Mayes, Sequoyah, Tulsa, Wagoner and Washington.
A flash flood watch is in effect for most of northeastern Oklahoma through Monday morning.
Numerous showers and storms are likely through the afternoon and evening hours in Green Country. These storms are forming along a slow-moving frontal boundary situated, as of 3 p.m., northwest of I-44.
The primary threat with these storms into the early evening hours will be locally damaging winds along with flash flooding, especially in areas that have already received heavy amounts of rain in the past few days.
These storms will likely form into a complex and drop southeastward through the evening with some weakening expected after dark. Until then, stay weather aware and be prepared to seek shelter if and when storms threaten your area.
