Warm and mostly sunny through the day. Increased clouds in the north will cool temps a bit. Isolated showers and thunderstorms over the northern mountains.
A Red Flag Warning is in effect Thursday and Friday for portions of central and southern Wyoming as favorable weather conditions (very low relative humidity and gusty winds) develop. This covers Uinta and Sweetwater counties and portions of Lincoln, Sublette, Fremont, Natrona counties, and all portions of the South Pass area. New fires could spread quickly in these favorable weather conditions.
Here is the 3-month climate outlook for September, October and November. The white area is for locations with equal chances of above or below temperatures or precipitation. The majority of Wyoming will have a chance of above normal precipitation, except for a sliver in the west. Temperatures show above normal chances of 40% or better.
