Northward transport of Gulf moisture is forecast by the end of the
week and into next weekend on most global deterministic and ensemble
guidance. There is no clear time period of specific concern at this
time, but the overall pattern appears favorable for potential severe
weather concern at some point. There is reasonable agreement in a
large scale pattern favoring a western CONUS upper-level trough and
ridging in the east which should keep the warm sector inland and
allow the potential mid-level shortwave troughs to eject out of the
western CONUS trough and interact with this seasonably warm/moist
warm sector.
