  tomorrow afternoon due to breezy southwest winds and low
  humidity.

.SHORT TERM...  (Through Late Sunday Night)
Issued at 219 PM CDT Sat Mar 28 2026

After a chilly morning that saw widespread freezing temperatures,
another warmup is in store over the next several days as southerly
winds become re-established. We will also see the return of
shower/thunderstorm chances Tuesday onward as we enter a more
unsettled pattern.

In the near-term, the focus continues to be on some lingering fire
weather potential thanks to the presence of an exceptionally dry
airmass.

.LONG TERM...  (Monday through Next Saturday)
Issued at 219 PM CDT Sat Mar 28 2026

The peak of the warmth arrives Monday and Tuesday, as a broad, but
low-amplitude ridge nudges eastward and steady warm/moist advection
continues on both days.

Wednesday onward, the day-to-day details become much less clear, but
latest trends suggest that an active/wet pattern will likely
continue as another more substantial trough follows with additional
chances for showers/thunderstorms late in the week.
