.MESOSCALE UPDATE...
Issued at 625 PM CDT Sat Sep 27 2025
Drier air across the region continues to result in pleasant
evening conditions across the forecast area. Based on this
morning`s low temperatures, and with another good night of
radiational cooling expected, I lowered Sunday morning lows down a
degree or two in some spots. Otherwise, outside of the usual
tweaks to hourly elements of the forecast based on current
trends, no major adjustments will be made to the forecast on this
evening`s update. /19/

.DISCUSSION...
Issued at 224 PM CDT Sat Sep 27 2025
For the most part, high pressure will be in control of the weather
for the forecast area through the upcoming work week, and no
significant frontal passages are expected. As the tropical system
moves slowly up the southeast coast, there could initially be a
trough passage that corresponds with a slight uptick in rain
chances in our area. But that will be followed by an increase in
dry air advection in the boundary layer along with slightly
cooler temperatures as well, especially by late week. Otherwise,
no significant changes in the airmass are expected.
Given the long duration stretch of below normal rainfall, we will
be monitoring for any increased fire weather threats. As of now,
the RH/Wind elements look like they should remain below threshold,
but that could change if boundary layer mixing is greater than
forecast. /EC/
