Primary concerns to the fire area will be the potential for an isolated thunderstorm and more so thunderstorm outflow winds, that will be capable of creating a sudden increase in wind speeds as well as sudden wind shifts. Isolated thunderstorm chances today will extend from now through around 2000MST this evening. Odds of seeing outflow winds in excess of 35 mph is around 50% and the favored direction to see an outflow is from the south to east. The ambient conditions will continue to favor south to southwest until shifting east to southeast around 1800-1900MST. The east to southeast wind this evening will be capable of gusting upwards of 25-30 mph through midnight. Winds should subside overnight with a persistent east, to northeast drainage, through Saturday morning. Heading into Saturday afternoon ambient winds should veer southerly with speeds remaining light. The potential for thunderstorms Saturday afternoon will be slightly higher than today, up to 30-40%, beginning as early as 1300-1400MST. However, cloud cover may limit the thunderstorm potential. Temperatures Saturday will not be as hot as today and moisture will be on the rise over the next 24 hours.
