A dryline positioned from Alva to Clinton to Altus Oklahoma to Vernon and Benjamin Texas at 3 PM. It is forecast to move to a line from Cherokee to Watonga to Lawton Oklahoma to Seymour Texas by 5 PM.
To the west of the dryline southwest winds from 25 to 35 mph with higher gusts will occur along with temperatures in the 90s to around 100 degrees and relative humidity below 15 percent. Extreme wildfire potential will exist west of the dryline throughout the afternoon and well into the evening.
East of the dryline, winds will be from more of a southerly direction but will still be strong in the 20 to 30 mph range. Greater low level moisture content will be present east of the dryline but wildfire potential will still be very high. Caution should be taken to prevent the ignition and spread of outdoor fires this afternoon across the entire area.
A strong capping inversion is expected to prevent thunderstorm development through at least early evening. A strong cold front bringing an abrupt change to strong northwest winds in the 25 to 35 mph range is forecast to progress from far northwest Oklahoma at around 8 PM to a line from Hollis to Stillwater by around 1 am.
Though unlikely…thunderstorms could possibly form along the cold front east of Interstate 35 late tonight.
