.Aviation [02/18z Issuance]...Vfr Conditions Will Continue Through
The Period As High Pressure Dominates The Central Gulf Coast. /13

.Short Term [Today Through Tonight]...There Several Upper Features
To Not...A Low Drifting Around The Western Gulf Of Mexico Between
Two Ridges...One Over The Desert Southwest And Another Ridging South Of Hurricane Earl. The Coupling Between The Latter Two Is Pulling Midlevel Dry Air Into The Area As Hurricane Earl Moves Up Along The East Coast. A Mid Level Trough Further North And Moving East Across The Missouri Then The Ohio Valley In The Next 24 Hours. This Will Bring Frontogenetic Processes Into Play At The Surface But They Are Rather Weak As Are The ThermalGradients, Advection And Other Kinematics That One Normally Sees Much Later In The Year.
Nonetheless There Is A Weak Boundary There That Will Approach The
Area By Early Friday. Precipitable Water Numbers Indicates The
Atmosphere Will Be Bone Dry For The Next Day With A Slight Rebound
About A Quarter Inch Is Possible Ahead Of The Front. Highs In The
Mid 90s Inland Today And Low 90s Along The Coast. /77

.Long Term [Friday Through Wednesday]...High Pressure Over The
Southeast Is Forecast To Break Down By The Latter Half Of The Week
As A Dry Frontal Boundary...Sinking Into The Deep South Late Friday
Will Move Offshore And Stall By Saturday. The Front Will Bring
Scattered Clouds Across The Forecast Area...But No Rain Is Expected.
High Pressure Will Then Rebuild Across The Southeast States Over The
Labor Day Weekend...Keeping The Forecast Area Dry. The Drier Air
Mass And Sunny Skies On Friday Will Allow Afternoon Temperatures To Climb Into The Mid 90s North Of I-10...And The Lower 90s South Of
I-10. Lows Friday Night Will Range From 64 To 70 Degrees Inland
Areas...And Range From 70 To 75 Degrees Coastal Sections. Maximum
Heat Indices Both Afternoons Will Range From 95 To 99 Degrees.

Cooler Temperatures Will Occur Over The Labor Day Weekend Through
The Middle Of Next Week With The Passage Of The Front. Highs Will
Range From 88 To 93 Degrees Each Day. The Coolest Temperatures This Forecast Package Will Occur Both Saturday And Sunday Night...With Lows Ranging From 56 To 62 Degrees Well Inland...And The Mid 60s To Lower 70s Over The Southern Zones. Low Temperatures Will Then Moderate Monday Through Wednesday. /22

.Marine...That Ridge Mentioned Over The Bahamas Will Dominate The
Weather Through Today Before It Weakens Ahead Of A Weak Cold Front Moving Toward The Gulf Coast And Offshore Late Friday Into Saturday. A Light North Wind Will Follow Behind The Front This Weekend. By Monday Next Week Light To Moderate East Winds Will Dominate The Picture With Little Rain In Sight. /77

.Fire Weather...Drier Air Will Slowly Push South Into The Area Over
The Next Few Days...With No Rainfall Expected Through Labor Day
