A cold front slowly sinking south into the Carolinas and Mid-South is bringing a return to near-normal temperatures along with much needed rainfall for many locations that have experienced 100+ degree temperatures over the past few days. Scattered strong to severe thunderstorms are likely to develop in the vicinity of this front as it moves slowly southward. Out west, a combination of moist southerly monsoonal flow aloft and easterly surface upslope flow is likely to produce scattered showers and thunderstorms from the Front Range of Colorado into Mexico through Wednesday. This will help to alleviate the drought and limit wildfire growth potential. Over parts of Oregon, Washington state, and Idaho, some strong thunderstorms will be possible as mid-level disturbances track around the northern periphery of a high pressure ridge that is centered over the Desert Southwest.
There are critical Fire Weather areas for southwestern and south-central Montana, parts of Idaho, and far northwestern Wyoming today. Dry thunderstorms are predicted for the same areas. Red Flag Warnings continue for the interior Northwest and northern Rockies, where abundant lightning over a region of dry fuels may pose a threat for new fire starts.
