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.
