The Activity Should Reach The Mccomb And Baton Rouge Areas By
Early This Evening...the Northshore And New Orleans Metro Areas By
Midnight...and Move East Of The Area By Sunrise. Damaging Winds And
Heavy Rainfall Will Be The Main Threats With Any Severe Storms That
Develop.


New Orleans Local Weather thread - ROLLTIDE - 04-26-2007 12:14 AM

This Hazardous Weather Outlook Is For Portions Of Southeastern
Louisiana And Southern Mississippi.

.day One...tonight

A Slight Risk Of Severe Thunderstorms Continues Across Southeast
Louisiana...southwest Mississippi...and Coastal Mississippi Tonight.
These Thunderstorms Are Expected To Form Ahead Of And Along An
Advancing Cold Front. The Main Threat For Severe Thunderstorms Will
Transition From The Mccomb And Baton Rouge Areas Early Tonight...to
The New Orleans And Gulfport Areas After Midnight. All Of The
Severe Thunderstorm Activity Should Clear The Region Before
Sunrise. Damaging Winds And Heavy Rainfall Will Be The Main Threats
With Any Severe Storms That Develop.

.short Term...
No Surprises With This 7 Day Fcast. Temps Should Fall Close To
Where They Were Yesterday With A Few Degrees Tacked On. Some Ht
Falls Are Noticed As Weakening 700mb Thermal Trough Moves Over The
Area Today. So Cooling Temps Should Be Felt Over The Entire Area
Today. Enjoy It...it Doesn`t Last Long This Time Of Year.

.long Term...
The Long Term Will Be Plagued With A Continual Warming Trend And
Little In The Way Of Any Major Changes.

.short Term...
Some Slight Changes Coming Toward The Middle Of Next Week. But For
The Short Term No Problems Expected. A Very Weak Trough Will Pass
The Area Today With About The Only Notable Thing Being Cloud
Cover. Will Keep The 10% With No Mention For A Sprinkle Or Two.

.long Term...
The Northern Branch Will Be More Active Than The Southern Branch
Jet...which Is Normal For This Time Of Year. The Southern Branch
Actually Becomes Almost Non-existant By This Time Of Year As The
Northern Branch Pulls Well Northward Over Northern Canada. This
Will Conitinue For The Next Several Days Where The Sluggish
Systems Slow And Stall As They Reach The Area. Wed Looks To Be No
Surprise As This Should Be The Scenario. The Upper Trough That
Develops By Tue Quickly Moves Through Passing Up The Sfc Low Over
Tx. As The Upper Ridge Builds To The North...the Mid/sfc Low Has
Nowhere To Go. This May Cause A Problem Over East Tx And Western
La By Mid To Late Next Week As Moderate Impulses Move Out To The
Ne Around The Low Causing Sh/ts To Train Over The Same Areas.
Placement Will Be The Only Concern For This Area With Respect To
Getting Rain Or Not.

.discussion...high Pressure At The Surface Continues To Prevail
This Morning Across The Eastern Gulf With Southerly Flow
Continuing To Usher Moisture Into The Region. A Gradual Movement
Toward The Atlantic Basin Is Expected With The High Pressure For
Much Of The Work Week As Modified Polar Surface Boundaries Move
Into The Lower Mississippi Valley Around Mid Week. Little Surge
Behind These Boundaries Though Look To Keep These Features Well
North Of The Forecast Area With Relatively Warm And Humid
Conditions Persisting Into The Weekend Period. A Weak Shortwave
Trough Aloft Though Looks To Slowly Traverse Across The Southeast
States On Thu Which May Lead To Some Much Needed Shower And Tstm
Development Mainly Thu And Possibly Continuing Into The Weekend
Period. At This Point...rain Chances For This Weekend Look To Be
In The Slight Chance Cat Although Would Not Be Surprised To See
Future Model Runs Be A Bit More Aggressive With The Passing
Shortwave Aloft Which Is Typical For This Time Of The Year.

...flood Watch Now In Effect From Late Tonight Through Friday
Afternoon...

The Flood Watch Is Now In Effect For

* Portions Of Southeast Louisiana And Southern Mississippi...
Including The Following Areas...in Southeast Louisiana...
Ascension...assumption...east Baton Rouge...east Feliciana...
Iberville...livingston...lower Jefferson...lower Lafourche...
Lower Plaquemines...lower St. Bernard...lower Terrebonne...

Han****...harrison...jackson...pearl River...pike...walthall
And Wilkinson.

* From Late Tonight Through Friday Afternoon

* A Strong Upper Level Disturbance Moving Across Texas Today Will
Move Slowly Across The Lower Mississippi Valley Tonight And
Friday. A Moisture Rich Atmosphere Will Be In Place As Southerly
Flow Persists And Increases In Strength Tonight And Friday Over
The Area. Rainfall Rates Of One To Two Inches Per Hour Will Be
Possible At Times With Thunderstorms Late Tonight And Friday
Resulting In The Threat Of Flooding. Some Numerical Forecast
Models Are Indicating Copious Rainfall Amounts That May
Materialize...including Accumulations Between 3 And 6 Inches
Within Six Hour Periods. If This Occurs...then Flooding Can
Ensue And Possibly Become Extensive.


* Potential Impacts Of Flooding Include Extensive Ponding And
Flooding Of Streets And Urban Areas Where Torrential Rains May
Briefly Overwhelm Drainage System Capacity. Excessive Rainfall
Runoff Typically Causes Rives And Streams To Rise Rapidly. Most
Area Steams Are At Low Flows And Should Be Able To Accommodate
Low To Moderate Rain Rates And Accumulations. If Rain Rates
Become Torrential...typically Exceeding Two Inches Per
Hour...then River And Stream Flooding May Result. The Lower
Mississippi River Forecast Center Will Be Evaluating The River
Flows Throughout The Day And May Issue A Hydrologic Outlook
Highlighting Any Potential River Flood Concerns.

A Flood Watch Means There Is A Potential For Flooding Based On
Current Forecasts. You Should Monitor Later Forecasts And Be
Alert For Possible Flood Warnings. Those Living In Areas Prone To
Flooding Should Be Prepared To Take Action Should Flooding
Develop. The Early Issuance Of This Watch Is To Provide Ample Time
For Individuals And Municipalities To Take Preparedness Measures
To Lessen The Flood Threat. Take Time To Clear Storm Drains And
Catch Basins Of Debris.

In The Wake Of A Very Active Day On Friday...much More Tranquil
Weather Conditions Will Prevail Across The Forecast Area Through
The Upcoming Week. An Amplified Upper Air Pattern Will Prevail
Across The Conus During The Period With An Upper Level Ridge
Building From The Gulf Coast To The Great Lakes Region Over The
Weekend While A Deep Trough Remains Over The Western U.s. And Another
Trough Moves Across The Northeast And Becomes Anchored Off The
East Coast Early In The Upcoming Work Week. The Upper Ridge
Initially Extending From The Gulf Coast To The Great Lakes And
Then Over The Gulf Coast And Southeast U.s The Will Dominate The
Local Area Weather Through Much Of The Period. A Weak Disturbance
Moving Out Of Texas May Ignite Isolated Convection Today...however
With The Upper Ridge Becoming Fully Entrenched Across The Region
By Sunday Little In The Way Of Convection Is Anticipated For The
Last Half Of The Weekend. Much Of The Upcoming Work Week Will Be
Dry...although There Will Be Some Chance For Convection Again
Monday As Another Weak Disturbance Affects The Area And The
Remains Of A Back Door Frontal Boundary Attempts To Work Into The
Area. Drier Air Will Filter Into The Forecast Area By Tuesday As
Surface High Pressure Shifts South And Southwest Along The East
Coast And Into The Southeast. The Western U.s. Upper Trough Will
Slowly Work Its Way East Into The Central And Southern Plains And
Weaken By The End Of The Week. This May Bring A Little Better
Chance Of Convection Back Into The Area Friday Or Saturday.
