.KEY MESSAGES... Updated at 1230 AM CDT Sat Sep 27 2025
- Min RH`s drop into the 20-30% range for the Brush Country/Inland Coastal Plains today, though fire risk remains above thresholds given weaker winds.
- Seasonable temperatures with fresher mornings thanks to drier air remaining in the region through mid-week.

.DISCUSSION... Issued at 1230 AM CDT Sat Sep 27 2025
The transition to a ridging pattern aloft will allow for the fresh mornings and more seasonal highs through Tuesday. Then a Four Corners shortwave moves through Texas, allowing more for a wind shift and helps maintain lower PWATS (1.0-1.2" across South Texas). This shortwave moves into the Southeast and just sticks around the region into the upcoming weekend. Having this in the vicinity and with surface winds having more southeasterly components to it will allow for seabreeze convection. For this reason, NBM is showing low chance (20-30%) PoPs over the western Gulf with only the coastal zones having the greatest chance for isolated showers and storms. Not much to brag about, but we`ll have a better idea of the spatial coverage of any shower activity in the subsequent days.
Main adjustments made to this forecast was for minimum relative humidity values for today as NBM had a wetter bias for yesterday`s afternoons forecast. For this reason, I blended down to allow Min RH to bottom out in the 25-35% range (except for the immediate coastline which will drop into the 40-60% range).
