It will be an interesting weather weekend for southeast Texas as we prepare for our first significant cold front of the fall.

Highs on Friday and Saturday will be near 90 degrees with 20 percent rain chances Friday and early on Saturday, increasing to 30-40 percent in the late afternoon and evening, as the front approaches and moves through.

As of Friday morning, the front will move through between 8 p.m. Friday and midnight Saturday with gradual clearing through the overnight and early morning, along with a drop in temperatures of about 30 degrees from Saturday's high.

On Sunday, look for a starting temperature near 60 degrees with breezy conditions and high near 80.

Monday's low will be even more definitive with lows near 50 and upper 40s in outlying rural areas quite possible.

KPRC meteorologists are also keeping an eye on Tropical Storm Karen which is moving to the north northwest at about 10 mph with sustained winds of 60 mph. That’s a decrease in strength from Thursday's consistent readings.

TS Karen is expected to slow down and possibly strengthen as it approaches the Louisiana coast by Saturday afternoon.

Landfall is expected east of Louisiana along the Northeast Gulf coast in the Mobile, Alabama, Pensacola, Florida area.

Karen is not expected to impact southeast Texas.
