Valid 101200Z - 151200Z



...DISCUSSION...

A progressive upper-level pattern is forecast during the Day

4-8/Sun-Thu period. Early in the period, an upper trough will move

from the Plains to the eastern U.S. through Day 5/Mon. Stronger

northwesterly flow will overspread the Plains during this time,

while a cold front will sag southward across TX and Gulf Coast

states. This will suppress boundary layer moisture across much of

the CONUS, but could bring some potential for strong thunderstorms

to parts of TX and the Southeast, though severe thunderstorm

potential appears marginal. 



By Day 6/Tue, a deepening surface low is forecast across the central

Plains as a weak shortwave impulse migrating through northwesterly

flow aloft glaces the region. Increasing southerly low-level flow

will begin to transport Gulf moisture northward across portions of

the central U.S. through Day 7/Wed, and some increase in

thunderstorm potential is expected. At the same time an upper ridge

will begin to emerge over the Plains, which could lead to capping.

Additionally, quality of moisture return is uncertain with northward

extent. Overall, severe potential appears marginal throughout the

Day 4-8/Sun-Thu period.
