General Discussion: The cold front moved through Amarillo around 6AM this morning, and temperatures dropped about 20 degrees within 3 hours. This will be the first strong cold front of the season – and it will push all the way through Texas over the next 36 hours, clearing South Texas Friday afternoon. Ahead of the front, very warm to hot temperatures along with fairly high humidity. Some temperature records are likely to be broken today with widespread 90s this afternoon. The front will move through Dallas-Fort Worth tonight – before midnight, then move through Austin and San Antonio around daybreak on Friday. The front will reach Houston by late-morning. Much cooler behind the front Friday and Saturday. 30 degree differences common between today and the next couple of days. Temperatures will begin to rebound warmer Sunday afternoon. Next Monday into Tuesday should be quite warm again – borderline hot in many cases with 90-degree highs again possible. Another cold front is due around Wednesday of next week. This front doesn’t look as strong and temperatures could very well rebound much warmer again Friday into next weekend. It’s very much a temperature roller coaster – and noting that there’s still plenty of very warm/hot potential ahead in October.

Today: The strong cold front will be moving through West Texas today with some very large differences ahead of versus behind the front. A strong north wind will develop behind the front. Highs well into the 90s for most of ERCOT today. Showers and thunderstorms will form along and ahead of the cold front, possibly severe in North Texas this evening/tonight. The storms will become more scattered and less intense as they move south-southeast along and ahead of the front late tonight into tomorrow.

Tomorrow: Most locations will see their high temperature for Friday recorded overnight tonight. Temperatures will take a nose dive when the front moves through – along with a gusty north wind. Temperatures Friday afternoon will only be in the 50s in Dallas, upper 50s to near 60 in Austin and San Antonio, and low 60s – possibly falling lower than that – in Houston. Much of the Panhandle will see its first freeze tomorrow morning. Scattered showers and thunderstorms tomorrow morning across Central Texas to the Coast, moving into South Texas tomorrow afternoon. May be a separate area of rain in southern portions of West Texas as well Friday afternoon. Not as strong nor widespread as when the precipitation reaches North Texas this evening – but most locations will at least have a chance of rain.

This Weekend: Quite chilly on Saturday with morning lows in the 40s and afternoon highs in the 60s common. Turning warmer on Sunday afternoon with 70s and 80s returning. Rain chance in/near Houston on Sunday.
