.SHORT TERM... (Today and tonight) Issued at 1203 AM CDT Fri Sep 26 2025
Quiet conditions will prevail through the short term period as the upper level ridge moves overhead from the west as an H5 shortwave trough and associated low moves onshore the SOCAL coastline. This synoptic pattern will induce lee cyclogenesis, veering winds across the region out of the southwest. These warm southerly winds combined with increasing thickness and height values with the ridge overhead will influence much warmer temperatures this afternoon in the 80s and 90s. Additionally, the forecast looks dry across much of the region as large scale subsidence beneath the ridge suppresses precipitation potential. Tonight, expect temperatures to be warmer compared to what we saw overnight Thursday in the mid to upper 50s as light southerly winds continue.

.LONG TERM... (Saturday through Thursday) Issued at 1203 AM CDT Fri Sep 26 2025
The upper level ridge, although rather weak, will remain on hold through much of the weekend as the upper level trough and associated low slowly tracks through portions of the Desert Southwest. By Saturday the low will be centered across the SOCAL/AZ region while the FA remains encompassed by the western side of the ridge. Flow aloft looks to remain relatively zonal through most of Saturday before we see flow begin to back out of the southwest late Saturday night into Sunday morning. This moist southwest flow aloft will work to transport beneficial subtropical/monsoonal moisture into parts of the region. Similar to previous forecasts, the upper level system will begin to weaken while ejecting into the Four Corners region by Sunday. Resulting in much of the lift and beneficial moisture to our west across portions of NM and AZ as flow aloft becomes more southerly, with H5 jet and moisture plume centered across central NM. This will likely limit the overall precipitation chances across the region with the highest chances fixated across areas along the TX/NM state line. Although precipitation looks less likely, we could see some slight relief come Sunday but first we must get through another unseasonably warm day on Saturday with highs in the mid 80s to lower 90s. To start the new week, height falls correlated with the H5 trough moving towards the Rockies along with southwest winds backing out of the southeast in response to the surface high shifting east will aid in slightly cooler highs Sunday into the start of next week. There is some indication amongst models of a stratus deck lingering through portions of the day on Sunday but confidence in this is quite low to factor in potential effects of this to the highs. An additional upper level trough will begin to dig into the PacNW by mid-week next week, shifting a ridge into the West Texas region which will bring the return of unseasonably warm and dry conditions.
