.DISCUSSION...
Issued at 335 AM CDT Sun Aug 31 2025

Little in the way of hazardous weather impacts are expected for
our region through this week.

A persistent and unseasonably deep eastern CONUS longwave trough
will be the primary weather influence for the area as we go
through next. Most of the forecast will be on the dry side, but a
few sneaky disturbances sliding through the cyclonic flow aloft
will bring a few days of light rainfall potential with low to
medium rain chances that peak in the afternoon. This is especially
the case for Tuesday north of the I-20 corridor when a more
significant shortwave trough is expected to slowly cross the TN
Valley region.

By late week, reinforcement of the eastern CONUS trough may bring
cooler air into our forecast area. Lows in the upper 50s should
become more common by Friday night over northern portions of the
area, but the prospect for cooler air reaching south of I-20 is
looking less certain as the cool anomalies remain centered north
of our area. /EC/
