Surface high pressure across the western Gulf tonight slides farther eastward on Friday allowing southeasterly flow to return. Friday into the middle of next week looks be rather quiet with above normal temperatures and dry weather as a mid-level ridge builds over the region.

High temperatures Friday through Thursday are expected to reach the 80s each afternoon, except along the coast. High temperatures on Wednesday may reach 90 degrees in a few locations across the Upper Valley and the Rio Grande Plains.
