Early this afternoon…a warm front was developing from Ponca City to Fairview to Woodward. Gulf moisture had surged into much of Oklahoma and North Texas. The western edge of humid air extended from Knox City and Vernon in Texas…to near Clinton and Fairview in Oklahoma. As vertical mixing increases this afternoon…the western edge of Gulf moisture will become better defined as a dryline. The dryline may mix eastward slightly…but should remain positioned over western Oklahoma and western North Texas. Meanwhile…low pressure will deepen in Colorado…resulting in increasingly gusty southerly winds. Fire weather concerns will be greatest west of the dryline…while a few strong thunderstorms are possible east of the dryline and near the warm front. Thunderstorm development is not expected until 4 PM or later.
