Monday, the upper low will continue to deepen over parts of southeast TX and limited boundary-layer moisture will advect northward in response to its approach.  Ridging aloft and weak lapse rates will limit instability, but should storms evolve, especially along the coastline, the shear in place definitely supports supercells and isolated tornadoes.  Nevertheless, much needed rain will develop in drought-stricken Texas and flash flooding is possible in some areas, with up to 4 inches of total rainfall possible by tomorrow night / early Tuesday.

Tuesday, rain will linger across SE Texas as the upper low moves further east across extreme Eastern TX.  Deeper moisture is expected to push north through SE AR, LA, MS and AL, where a warm front will exist.  Again, instability will be limited, but shear profiles are supportive of supercells, including tornadoes.  Heavy rain will also exist in these areas and flash flooding is definitely possible across the mentioned areas.
