...DISCUSSION...
Medium-range guidance continues to show a period of quiescent
weather through at least Thursday as upper ridging traverses the
Plains. A strong shortwave trough is expected to move into the
Plains on Friday, continuing northeastward into the upper MS Valley
while another shortwave moves into the southern Plains. This second
shortwave trough may encounter enough low-level moisture to support
thunderstorms over the weekend along the Gulf Coast. However,
variability within the guidance remains too high for much forecast
confidence.
