783 FNUS63 KABR 300800 RFDABR Rangeland Fire Danger Statement National Weather Service Aberdeen SD 300 AM CDT Tue Sep 30 2025 .DISCUSSION... A tight pressure gradient between the high to the east and a low to the west will continue to support a low-level jet over the region. Jet strength will be about 30 to 45 miles per hour, and as a result, gusts of 25 to 35 miles per hour are expected to mix to the surface beginning this afternoon over central South Dakota. Coverage will expand this evening to the rest of the CWA, and gusts up to 35 miles per hour are expected through Wednesday afternoon. By Wednesday evening, the near-surface pressure centers (and therefore the low- level jet) will begin to progress eastward, taking the stronger surface winds along with them. Abnormally moist air for this time of year (dew points in the upper 50s to low 60s) will keep minimum afternoon humidity well clear of any potential Red Flag concerns, ranging from 35 to 50 percent both today and Wednesday.
