The synoptic, upper-air pattern will begin a change today. Amplified ridging will build along the west coast of the United States and deep troughing will ensue across the eastern 2/3 of the CONUS. This will allow a Canadian airmass to dive south into Texas over the weekend. The cold front should approach the Red River counties of North Texas by tomorrow afternoon. Compressional warming ahead of the front will allow for temperatures to climb into the upper 90s as far south as the I-20 corridor for highs on Friday. Showers and thunderstorms will break out along the front. Rain chances will spread form north to south as the front progresses south. This is not expected to be a heavy rain event as it will be relatively short in duration as the front passes. Behind the front, much drier and subsident continental air will spread in as the surface high builds southward. Temperatures will be a good 8 to 12 degrees cooler behind the front with highs in the 80s and lows in the mid-to-upper 60s. Not bad for June in Texas!
