.LONG TERM...
(Wednesday night through next Monday)
Issued at 232 AM CDT TUE APR 30 2024

Mid-level ridging extending from the Gulf through the eastern
CONUS Thursday will result in above normal temperatures for early
May. A convectively enhanced shortwave/MCV moves in from the west
late Thursday afternoon and Thursday night. Mid-level moisture
increases but low-levels remain fairly dry, so will only include
low chances for showers in the forecast. Quasi-zonal flow aloft
will then set up for the rest of the period, north/northeast of
subtropical ridging building over Mexico and the southwestern
Gulf. Various weak shortwaves emanating from the Southern Plains
combined with above normal PWATs for this time of year will result
in at least isolated to scattered showers and storms each day,
highest chances north further removed from the ridge. A bit more
coverage will be possible Friday afternoon and Friday night across
the far north as a cold front stalls to our north and then lifts
back to the north.
