Heavy rain will create a threat for flooding during this period. - Additional storm chances return late in the weekend into early next week. && .SHORT TERM... (This afternoon through Wednesday) Issued at 138 PM CST Tue Nov 18 2025 Another toasty November afternoon is unfolding across the region, with record-breaking temperatures expected. Optimal conditions for compressional warming are in place, as winds have veered out of the west to southwest ahead of a weak cold front in southern Oklahoma. This is allowing temperatures to soar into the mid to upper 80s for most locations this afternoon, with a few locations west of I-35 potentially reaching the 90 degree mark. The record high temperature at DFW Airport has already been broken as of 12:05 pm, breaking the previous record of 83 degrees set in 1973. Waco briefly reached 85 degrees at 11:58 am, breaking the previous record of 84 degrees set in 1905 and 1941. A weak cold front in southern Oklahoma is expected to slide across the Red River into North Texas late this afternoon and into the evening. Surface winds will likely resume a southerly direction this evening as the front enters the area, which may provide enough convergence along the front to result in the development of isolated showers across portions of North Texas. While there will be an axis of instability oriented from southwest to northeast across portions of North Texas, showers will either develop north of the instability or encounter too much mid-level dry air to amount to anything significant without a more substantial forcing mechanism. On the off chance a more robust updraft is able to develop, the main concern would be an isolated lightning strike. A 10% chance for showers and isolated storms has been introduced with this update to reflect this potential. Quiet weather is expected for most of the day Wednesday. Isolated showers will be possible across Central Texas beginning Wednesday morning, with some of this activity potentially continuing into the afternoon. Storm chances will begin to increase across western North and Central Texas late Wednesday afternoon (at the very earliest) as large-scale ascent moves in from the west with the arrival of a shortwave trough. However, most of the activity associated with this shortwave will hold off until Wednesday evening and will be discussed in the long-term discussion below. && .LONG TERM... (Wednesday night through next Monday) Issued at 138 PM CST Tue Nov 18 2025 Showers and thunderstorms will increase in coverage Wednesday evening through the overnight hours. Storms will begin across western North and Central Texas and gradually expand east throughout the night. Some of this activity (especially the initial activity) will have the potential to become supercellular, which will pose a threat for isolated large hail. This will primarily be for areas along and west of the I-35 corridor. Low-level wind fields aren`t particularly favorable for a tornado threat, but we`ll have to monitor the effects of the low-level jet and thunderstorm timing. There may be a very brief window where an isolated tornado can`t be ruled out, especially if storms develop earlier in the evening. Locally heavy rain will also be possible with any of the activity Wednesday evening/night. Coverage of showers and storms is expected to increase through the remainder of Wednesday night as the parent trough of the leading shortwave approaches from the west. Additional widespread showers and thunderstorms are expected to develop on Thursday and move east throughout the day. Given the minimal instability on Thursday, severe weather is not currently expected. However, occasional gusty winds can`t be ruled out, especially with any clusters/lines of storms that are able to develop. On the other hand, the threat for flooding will increase with this second round of showers and thunderstorms, but where flooding is anticipated will largely depend on where the heaviest rain occurs Wednesday night, as these two rounds will likely compound to create drainage issues for some locations. Expect rainfall totals between 1-2" on average across the region, but areas that see multiple rounds of heavy rain could receive upwards of 4"+ through Friday morning. A Flood Watch may be needed in the near future, but there is still some uncertainty in where these higher-end totals could occur. Therefore, we have held off on issuing one at this time but will continue to reassess, especially as additional CAM guidance comes in. Rain coverage will decline Thursday night as the trough eventually exits to our north/northeast. A cold front will move through the region on Friday and will be accompanied by cooler and drier air. Pleasant temperatures are expected over the weekend with highs in the 60s and 70s and lows in the 40s and 50s. Low rain chances will return on Saturday, with increasing chances Sunday into early next week as another low pressure system moves in from the west. Timing is still a bit uncertain given this is 5-7 days away, but latest ensemble guidance suggests we may have another potential for heavy rain. Stay tuned as more details come to light over the next few days. && .AVIATION... (18Z TAFS) Issued at 138 PM CST Tue Nov 18 2025 VFR will continue this afternoon, with SW winds near 10-15 knots. A weak cold front is expected to cross the Red River into North Texas late this afternoon or early this evening. Winds will resume a southerly direction this evening, which could provide enough lift for a few light showers to develop across North Texas near/south of the front, mainly between 00-04Z. The potential for any lightning will be low, but a stray lightning strike can`t be entirely ruled out. Chances for showers or an isolated storm will be around 10%. The front is not expected to reach any D10 terminals, with southerly winds prevailing through the overnight hours near 5-7 knots. MVFR ceilings are expected to develop across the region Wednesday morning, but current guidance keeps the ceilings outside of D10 at this time, though there will be a brief window between 16-20Z where intermittent MVFR ceilings will be possible at North Texas terminals. The potential for MVFR ceilings is slightly higher at KACT, so MVFR ceilings were maintained in the TAF. However, these could end up being more intermittent at KACT as well. Otherwise, isolated to scattered showers are possible in Central Texas Wednesday morning, but confidence in any impacts to KACT is too low to include in the TAF at this time. Southerly winds will prevail on Wednesday, with wind speeds AOB 10 knots. Rain/storm chances will increase Wednesday evening outside of the extended TAF period. && .PRELIMINARY POINT TEMPS/POPS...
