- Above-average temperatures remain through the forecast period.
DISCUSSION
Issued at 134 PM CDT Sun Sep 20 2026
Mid-level high pressure continues, of course, but there is the potential for slightly more interesting things happening at the surface. Low rain (15-25%) chances will return Monday as PWAT values reach 1.7-2.0" and outflow boundaries from storms to the north move toward the coast, colliding with the seabreeze. Low rain chances will continue along the seabreeze Tuesday.
The NBM continues to indicate PoP values in the 20-50% range beginning Wednesday but, as the previous forecast mentioned, based on global models and understanding the NBM bias, expect these will continue to trend drier. South of the area, more moisture will result in higher rainfall totals. The NBM may be picking up on this and nudging it a little too far north. Either way, we'll keep an eye on this and update the forecast as needed.
AVIATION
