.SHORT TERM... (Today through Sunday) Issued at 107 AM CDT SAT SEP 13 2025
We`ll have plenty of sunshine to enjoy this weekend with the expansive ridge dominating the weather pattern. Continental flow will continue to provide dry air to the region with widespread subsidence promoting stable conditions with relatively light winds. Temperature trends have mostly begun to stabilize, so highs will be similar to yesterday ranging from the lower 90s west to upper 80s east. High surface pressure extending southwest through the Mid- Atlantic into Central Alabama will promote cool northeasterly flow tonight with lows in the 60s.

.LONG TERM... (Sunday night through next Friday) Issued at 107 AM CDT SAT SEP 13 2025
By Monday, guidance indicates a slight variation in the pattern with the development of a closed upper-level low over the Mid-Atlantic region. This feature may retrograde slightly to the west which could introduce some moisture to the area towards the middle of next week, especially in our east, but the overall model consensus at this time is maintaining the dominant ridge axis centered over the Mississippi River through at least Wednesday, so long-term PoPs will remain below 10% for the time being, and hot conditions are expected with daily highs in the upper 80s to low/mid 90s. There are signals that the ridge axis will finally begin to break down towards the end of the week in response to longwave troughing extending south from Canada into the Central Plains.

.AVIATION... (12Z TAFS) Issued at 652 AM CDT SAT SEP 13 2025
A VFR forecast is expected for the next 24 hours at the TAF sites thanks to surface high pressure across E Conus. Winds will be generally light and variable. MGM/AUO may see enough mixing to see E-NE winds 4-8kts.

.FIRE WEATHER...
Expansive ridging will continue to promote a hot and dry weather pattern through the weekend and into next week. Min RHs will drop into the 30-40% range for most of the area again this afternoon and this trend will persist into next week. Although values are currently forecast to remain above critical thresholds, drying soils will likely lead to expanding drought conditions. Winds should remain generally light from the northeast with occasional gusts due to daytime mixing.
