.MESOSCALE UPDATE...
Issued at 944 AM CST Tue Jan 13 2026

Not much to talk about for the morning update. Broad troughing over
the east CONUS will help keep weather conditions quiet and dry
across the southeast region. Sky conditions will be generally clear
over our forecast area this morning as a quick look at GOES 16
visible satellite shows a few high cirrus clouds over portions of
the area. Cloud cover will begin to increase from the southwest
later this afternoon. Afternoon highs will peak into the upper
50s/low 60s areawide. /CR/

.DISCUSSION...
Issued at 1131 PM CST Mon Jan 12 2026

Through early next week...

The synoptic pattern will be largely suppressed through the period
amid broad troughing over east CONUS. This will keep conditions
fairly dry and cooler than normal. The exception is Wednesday as a
Baja low ejects, resulting in weak moisture return. Therefore, rain
chances south of I-20 around 20-30%. A series of reinforcing cold
fronts mid to late week will maintain dry air. Conditions will be
favorable for freezing/subfreezing overnight lows through at least
early next week, which is below normal for this time of year. That
said, dangerous cold is not anticipated for much of the area, but
GTR may have to be monitored for cold headlines. Will keep posted in
future updates. We start to break the regime around mid next week,
the very end of the forecast period with subtle height rises and
restoration of southerly flow. This should bring lows back above
freezing for much of the area, with the exception of the Golden
Triangle (lows in the upper 20s), by Tuesday night. /SAS/

showers for southeast TAF sites after midnight for a couple of
hours, with additional light showers (14/14Z-18Z Wednesday) from
an approaching front at GLH, GWO and GTR. Some low-level wind
shear (LLWS) up to 30 to 35kts at 2kft is possible overnight to
mid- morning from 14/07-14Z Wednesday. Southerly winds around
10mph will turn westerly to northerly near the end of the 18Z TAF
cycle and gustier into Wednesday afternoon. /DC/
