Today Through Tuesday...
Our Weather Locally Will Continue To Be Dominated By The Proximity
Of The Large Upper High Over The Next Couple Of Days.
Temps At 850-Mb Will Be Just Shy Of Where They Were Yesterday And We Generally Shaved About A Degree Off The Temps That Were Observed On Saturday.
We Are Forecasting Actual Temps To Exceed 100 Mainly Over
Southwest Ga Today.
Upper 90s Will Extend South To About I-10 And West To Al.
Coastal Areas Will Benefit From The Sea Breeze With Temps Being Held In The 80s.
Heat Indices Will Be High Enough To Meet Local Advisory Criteria (108-112 Inclusive). We Extended The Southern Boundary Of The Advisory Just A Bit.
850-Temps Will Drop Off A Bit On Monday And Max Temps Should Come Down A Couple Of Degrees.
Slightly Higher Dew Points Will Compensate Though So That We Still Expect Advisory Level Heat Indices Along And North Of The Interstate.
By Tuesday, Heat Indices Should Remain Just Below Criteria With Most Inland Areas Seeing Highs Settle Back Into The Mid 90s, Far From Pleasant But A Step In The Right Direction.
As For Pops, Little Has Changed In Our Thinking Relative To
Convective Development. The Upper Ridge Will More Than Likely Be Too Strong To Allow Any Convection To Get Going Today. The Brief Shower We Saw Yesterday Quickly Dissipated.
That Said, The Piedmont Trough Will Be Closer To Us And Several Of The Convection-Allowing Models Insist That Storms Will Get Going To Our North And Possibly Impact Our Zones.
We Have Decided To Maintain Our Slight Chance Pop Forecast For Our Al And Ga Zones As Well As Inland Portions Of The Fl Panhandle.
While There Is Still A Considerable Chance That Convection Will Not Get Going, We Feel This Level Of Pop Is Warranted Due To The Extreme Instability That Will Be In Place. The 00z Ktae Sounding Indicated A Pronounced Elevated Mixed Layer With Good Mid Level Lapse Rates.
Any Storm That Gets Going Will Have The Potential To Grow To Severe Levels With Strong Wind Gusts The Primary Threat. We Are Still Not Confident Enough In This Forecast To Explicitly Mention Severe Storms In The Grids, But We Have Included Gusty Wind Wording. Similar Conditions (And Similar Caveats) Will Be In Place On Monday.
The Upper Ridge Is Expected To Begin Weakening Just A Bit And We Have Extended The Slight Chance Pop To Include All But Our Southeast Fl Big Bend Zones. Note That Spc Has Indicated That These 20-Pop Areas Have A 5% Chance Of Severe Storms Occurring Within 25 Miles Of A Point In The Day 1 And Day 2 Outlooks, Respectively.
The Ridge Will Further Weaken On Tuesday And We Bring In Some Low-End Chance (30) Pops Across The Northern Half Of The Forecast Area.
