AUSTIN (KXAN) — Austin observed its hottest day in a week and a half Wednesday, with highs reaching 102 degrees. Even hotter weather is in the forecast this weekend when rare Excessive Heat Warnings may be issued.

IN-DEPTH: Day and night temperatures are running the highest fever we have ever observed to date, and we have recorded more 100-degree days to date than ever before at Camp Mabry. Wednesday was Austin’s 27th 100-degree day so far this year — close to Austin’s typical total for an entire year.

Hot, dry and mainly sunny conditions can be expected each day through the week as a strong, August-like ridge of high pressure dominates over the southern U.S. Sinking air underneath this ridge will keep rain out of our forecast for awhile, with only the occasional rounds of morning clouds expected.

Although a quiet Atlantic basin during hurricane season is not necessarily a bad thing, a lull in tropical activity also means no meaningful or significant moisture coming in from the Gulf to bring us wetting rain.

Temperatures this weekend will challenge daily records and could prompt rare Excessive Heat Warnings in the Austin area. Whatever your plans, plan to stay hydrated and cool.
