Previous Discussion: /Through Monday Afternoon/

Record-breaking heat will be the main headline today as high temperatures soar into the mid/upper 90s across North Texas and triple digit heat in Central Texas. The late-season heat wave we've been experiencing for some time will linger for one more day before a cold front arrives tonight.

Before any major changes begin, the ingredients will be in place for temperatures to quickly rise this afternoon. The combination of record hot 850mb temperatures, southwesterly winds and compressional warming due to the incoming cold front will push temperatures into record territory. For DFW, we'll continue to advertise a high of 97 degrees which ties the previous record.
The limiting factor for additional warming in North Texas will be the arrival of a pre-frontal trough which will limit the amount of warming under northwesterly winds. Across Central Texas, the delay in the arrival of the pre-frontal trough will allow for temperatures to soar into the triple digits. Waco's record high temperature for today stands at 96F. This is 6 degrees below today's forecast temperature.

The cold front will arrive tonight, ending our record-breaking heat we've dealt with the last few days. Tonight, winds will increase to between 10-15 mph out of the north with gusts approaching 20 mph. A few locations west of the I-35 corridor will fall into the 50s with the rest of the region remaining in the 60s.

The cold front is expected to clear through all of North and Central Texas tonight. Temperatures on Monday will be 10-15 degrees below today's highs, a welcomed relief for many. Highs should be in the upper 70s to 80s for much of the region. Winds will continue out of the north/northeast between 10-15 mph.

LONG TERM
/Issued 252 AM CDT Sun Oct 13 2024/ /Monday Night Through Next Week/

The extended range forecast will be detailed by much cooler and more seasonable temperatures with dry conditions continuing.
Afternoon temperatures on Tuesday will slightly rebound to the mid and upper 80s to low 90s after an initial cold front pushes through the region on Monday. This will be short-lived as a second, more potent cold front sweeps through the region late Tuesday night into Wednesday morning. The passage of this second reinforcing cold front will drop afternoon highs into the mid 70s and low 80s areawide through the rest of next week. Overnight lows will fall into the mid 40s and low 50s for much of North and Central Texas as well, allowing for fall-like weather conditions.

Along with this cooler air, conditions will remain quite dry with the second cold front passing through the region rain-free.
Because of this, rain chances appear to remain quite low through the entirety of next week. There is a continued signal for the return of a more active pattern across the area next weekend. It is still a bit too soon to hone in on specifics as far as potential impacts go, but continue to check back for forecast updates as details become more refined over the coming days.

/NEW/ /12Z TAFs/

VFR and southerly winds continue across North and Central Texas this early Sunday morning. This will continue for several more hours before winds begin to veer this afternoon. Winds will go southwesterly to northwesterly over the course of today before a cold front turns North Texas winds out of the north tonight.

Aside from the expected wind shift, no significant weather impacts are expected through this TAF cycle.
