.UPDATE...
Issued at 813 AM CDT Sat Apr 20 2024
A much heavier than expected band of showers and isolated
thunderstorms developed overnight. The west to east band formed
on the north side of a surface frontal zone, generally along the
850mb cold front with help from a weak shortwave. These features
along with the weakening showers will move southeast of our area
by midday. Our far southern counties may have a few lingering
sprinkles on and off through the afternoon. Skies will vary
considerably across the area from mainly sunny northwest to near
overcast southeast. Varying mixes of clouds and sun will be seen
in between. Temperatures will be a few degrees cooler than normal
today with highs in the 60s. A steady north breeze will continue
10-15mph.
Another wave of light showers is expected late tonight into Sunday
morning, mainly south of I-40. Cooling north winds will continue
through the rest of the weekend with lows tonight in the 40s and
cooler highs for Sunday in the mid 50s to lower 60s.
The forecast was recently updated for the latest radar, temp, and
sky trends.
