One small difference to the models compared to yesterday. The upper level ridge building that has been going on should end tonight. The eastern side of the ridge should slowly collapse tomorrow into Sunday. As this transition progresses, it provides the opportunity for a return of a period of thunderstorms tomorrow night. Whether or not it rains tomorrow night, Sunday’s weather should remain hot, but with lower humidity. Sunday should be the hottest day with the highest temperatures (mid 90’s) but the heat index should peak today at slightly over 100 degrees. As for rain chances…10% this afternoon…20% tonight and tomorrow…30% late afternoon tomorrow and tomorrow night…10% Sunday.
