Northwest flow upper air pattern continues across the eastern

zonal pattern as an upper level low across the southwest CONUS
moves east over the Rockies and into the Plains on Sunday. Other

.LONG TERM... (Monday through Next Friday)
Issued at 200 PM CDT Fri May 10 2024

The aforementioned upper low will move across the Midwest Monday
and Tuesday and bring the region another good soaking. This system
has more of a "cool season" look to it with limited instability,
so the threat of strong or severe thunderstorms remain very low
for our CWA. Rainfall amounts are expected to range from a half
inch across the northern CWA to better than an inch along and
south of Interstate 70. Temperatures will be cooler Monday and
Tuesday with cloud cover and precipitation holding high
temperatures in the upper 60s and lower 70s.

Skies clear and temperatures rebound in the wake of this system on
Wednesday with highs surging back into the upper 70s and lower 80s.
The threat of thunderstorms return by Thursday evening and the
pattern looks more favorable for those storms to be strong or
severe.
