Upper Level Ridge Squeezes Rain Chances from Crossroads

A large upper level heat ridge is re-establishing itself from South Texas into the Desert Southwest late today,and its presence will shut down rain chance through the weekend. Also, look for the residual Gulf moisture to combine with trapped heat to create heat indices of between 105 and 109 degrees for the next several afternoons. By Monday, however, that upper ridge retreats to the west and allows a disturbance to move southeast out of the Rockies. That disturbance will bring a cold front into the region by Monday night and will be accompanied by scattered showers and thunderstorms. Isolated lingering showers will recur Tuesday, and temperatures by midweek will be a few degrees less hot.
