.DISCUSSION...
Issued at 1057 PM CDT Thu Oct 2 2025
Broad mid-level ridging over the central part of the country has
easterly flow through the lower and mid levels. A little higher
around 500mb, a trapped low pressure circulation along the Gulf
Coast has been causing isolated shower and storm activity in the
region. Expect a wave of drier air to move through tonight/tomorrow.
An arc of 0.8 PWAT air will wrap around the upper-level disturbance
across the northern half of our area tomorrow.
This weekend and into early next week, the center of the upper-
level ridge will translate northeastward to the Mid-Atlantic Coast
as troughing over the West Coast deepens. The resulting negative PNA
pattern over the CONUS will result in southwesterly flow aloft and
squeeze to easterly flow at the Gulf Coast. Expect deepening
moisture (PWATs near 2.0 inches) and a disturbance lifting into our
region to bring rain chances Sunday into the new work week. A cold
front pushing south into the region by late week will then serve to
focus additional shower or thunderstorm chances with more active
flow aloft. /NF/
