Synopsis...
The Large Scale Pattern Will Begin To Reamplify Over The Conus On
Sunday...Highlighted By Gradual Longwave Trough Development
Over The Canadian/Northern Conus Rockies And Plains.
Relatively Stable/Dry Conditions Will Considerably Limit Tstm Potential Across The Conus.
For East Tx/Arklatex...
The Onset Of A Warm Advection/Elevated Moisture Return Regime Could Account For A Low Probability Tstm Potential Sunday Night/ Early Monday Across The Arklatex Region...As A Cold Front Otherwise Spreads Southeastward Toward The Region.
However...Given The Likelihood Of Weak Forcing For Ascent/Lingering
Capping Aloft...Tstm Probabilities Currently Appear To Be Below 10
Percent Prior To 12z Monday.
