MONDAY...High Wind Potential. TUESDAY AND WEDNESDAY...No Hazards. THURSDAY...Very High Fire Weather Potential...High Wind Potential. FRIDAY...High Wind Potential. EXTENDED DISCUSSION... Fire weather conditions worsen Sunday with very dry fuels, low humidity, and windy conditions across eastern Oklahoma and northwest Arkansas. South winds gusting up to 35 miles an hour are anticipated during the day Sunday ahead of the cold front moving into the region Sunday afternoon. Behind the frontal passage, a wind shift out of the north with gusts of 30 to locally 40 miles an hour into Sunday evening are forecast. These conditions combined with near record to record high temperatures will create near critical grassland fire spread rates. The area of greatest concern remains across northeast Oklahoma, where locally critical spread rates could develop. Limited fire weather danger and cooler conditions start the next work week, though a warming trend and an increase in fire weather concerns develops for the second half of next week. weather.gov/tulsa contains additional information. $$
