Severe Weather Threat Day 2 Sun Oct 27

A Quasi-Zonal/Split Large-Scale Flow Regime Will Exist Over Much Of
The Conus On Sunday. A Weakening Southern Stream Mid-Level Trough Will Spread East-Southeastward Over The Gulf Coast States.
Meanwhile...A More Consequential Upper Trough/Polar Jet Will Dig
Generally Southward Over The Pacific Northwest And Northern Great

The Main Potential For Showers/Embedded Tstms On Sunday Is Expected To Be Across Parts Of East Tx/Upper Tx Coast Into La/Adjacent Ar. This Will Be Tied To Weak Ascent Associated With A
Southeast-Moving/Weakening Shortwave Trough And A Relatively Moist Airmass To The East-Southeast Of A Weakening/Stalling Frontal

Given The Anticipated Large-Scale/Mass Field Trends And Associated Weak Vertical Shear/Buoyancy...No Severe Tstms Are
Expected On Sunday.

Elsewhere...A Few Tstms Cannot Be Entirely Discounted Late
Sunday/Early Monday Morning Across Other Parts Of The Southern
Rockies To Southern Plains...Including Ok/North Tx Within An
Elevated Moist Advection Regime. However...Tstm Probabilities
Currently Appear Below 10 Percent For This General Scenario.
