A Significant Pattern Change Evolves During The Long Term Period With Hpc Preferring The Gfs Handling Of The Cut Off Low Over The Baja Area. A Longwave Trof Pattern Evolves Over The Eastern States Through Saturday With The Cut Off Low Opening Into An Open Wave And Being Absorbed By The Amplifying Pattern.

This Allows For The Surface High Previously Over The Central Plains To Build Into The Southeastern States On Thursday With Another Dome Of High Pressure Building Into The Plains And Bringing Another Reinforcing Cold Front Through The Forecast Area Friday Night Into Saturday.

With Increased Confidence In The Pattern Supporting A Trend Towards Cooler Temperatures...Will Have Slightly Below Seasonable Temperatures Through Saturday Trending A Bit Cooler Through Sunday In The Wake Of The Reinforcing Cold Front.

The Potential Development Of A Surface Low Over The Southwestern Gulf On Thursday May Still Occur...But Current Guidance Is Weaker With This Evolution And Takes The System More Eastward Across The Southern Gulf. This Leaves The Sole Mechanism For Possible Precipitation To Be A Series Of Vigorous Shortwaves Ejected From The Weakening Cut Off Low Over The Baja Area.

Moisture Looks Overall Too Limited To Keep A Mention Of Precip Over The Land Areas Thursday Through Thursday Night...But Does Look Sufficient To Keep Small Pops Thursday Night Through Friday Night Mainly Over The Southern Portion Of The Area.
