....DISCUSSION...
With appreciable low-level moisture remaining mostly offshore and
minimal instability forecast, severe potential across the CONUS
appears negligible on Day 4/Tuesday and Day 5/Wednesday. Another
upper trough is forecast to progress eastward over the western
states in this time frame. Modest low-level moisture should return
northward over the southern Plains ahead of a surface lee cyclone.
While some severe threat may materialize across parts of TX/OK on
Day 6/Thursday ahead of these features, forecast instability
currently appears too marginal to introduce a 15% severe area. An
isolated severe risk may continue into Day 7/Friday over parts of
the central Gulf Coast states as the upper trough advances eastward
over the MS Valley. However, considerable uncertainty regarding the
quality and northward extent of low-level moisture return preclude
any severe probabilities at this time.
