Oh I'm definitely in the wrong city. Born and raised in Houston and have a career in O&G so don't have a lot of choice on locale for now. Definitely going to retire outside of Texas one day.

Srain,
Maybe you should have Dan The WxMan introduce himself to the folks on the board.

The just Updated Climate Prediction Center Global Hazards Outlook has raised the NW Caribbean/Gulf threat to High Confidence for Tropical Development.
High confidence of tropical cyclone development in the northwestern Caribbean through the 20th. http://www.cpc.ncep.noaa.gov/products/p ... /index.php …

I'm in the wrong city too! LOL Born and raised in Wisconsin. Every summer I wonder why I moved here, but been in Texas 30+ years now. And when I go to sleep I look at the awesome man I moved here for.
And than winter comes and I go ahhh.... this is not so bad.
I work in O&G also, on the accounting side of things.

Up to 70%
A broad trough of low pressure is producing a large area of
cloudiness and showers over most of Honduras and the northwestern
Caribbean Sea. Conditions appear to be favorable for gradual
development of this large disturbance while it moves slowly
northwestward across the Yucatan Peninsula this weekend and into
the south-central Gulf of Mexico early next week. Regardless of
development, heavy rains are likely to spread over portions of
Central America, the Yucatan Peninsula, and western Cuba during
the next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...70 percent.

The overnight guidance is split between two camps regarding where the NW Caribbean Tropical Disturbance may eventually track. The ECMWF suggests a broad weak system moving into Mexico near or just N of Tampico while the UKMet is a bit stronger with the disturbance moving along the Texas Coast an inland very close to the Upper Texas Coast.
The second camp of the GFS, GFS Parallel and the Canadian move the disturbance NE into Alabama/Western Florida.
There continues to be tremendous uncertainty regarding the eventual track as well as the shear axis/cool cored upper trough expected to meander West from the Central Gulf Coast toward the NW Gulf early next week. Typically we see heavier showers and thunderstorms just to the East of these Tropical Upper Tropospheric Troughs which leads to forecasting complications. Other issues such as shortwave activity dropping South out of the Central Plains and a flattening SW Heat Ridge next week with approaching upper air disturbances arriving across the Pacific NW further complicates what our sensible weather may hold.
A Reconnaissance Aircraft is scheduled to investigate the Tropical Disturbance on Monday. My hunch is we may see an INVEST designated later today as the Overnight Ensemble Tropical Cyclone Genesis Outlook has increased to a 100% chance of TC Genesis during the next 48 to 72 hours.

Updated Weather Prediction Center Extended Range Discussion with the Bolded and Underlined Commentary regarding the likely Gulf System...
EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1200 PM EDT SAT JUN 17 2017
VALID 12Z TUE JUN 20 2017 - 12Z SAT JUN 24 2017
...RECORD HEAT OVER CALIFORNIA AND THE DESSERT SOUTHWEST THIS
WEEKEND WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK...
...A DISTURBANCE CURRENTLY BEING MONITORED BY THE NATIONAL
HURRICANE CENTER COULD BRING HEAVY RAINFALL TO THE GULF COAST NEXT
WEEK, BUT THE FORECAST REMAINS EXTREMELY UNCERTAIN...
...PATTERN OVERVIEW/MODEL EVALUATION...
AN EXPANSIVE UPPER RIDGE WILL REMAINED ANCHORED OVER CALIFORNIA
AND THE DESSERT SOUTHWEST THROUGH THE MIDDLE OF NEXT WEEK. FLOW
SHOULD BE FAST AND ZONAL NORTH OF THE STRONG RIDGE FROM THE
PACIFIC NORTHWEST TO THE NORTHERN ROCKIES, WHILE A DOWNSTREAM
BROAD UPPER TROUGH WILL IMPACT THE EASTERN HALF OF THE NATION
EARLY TO MID NEXT WEEK. CONFIDENCE IN THE LARGE SCALE FLOW OVER
THE U.S. BEGINS TO BREAK DOWN BY THE END OF NEXT WEEK, ESPECIALLY
OVER THE NORTHWESTERN U.S. WHERE DETERMINISTIC GUIDANCE IS SHOWING
A WIDE RANGE OF SOLUTIONS WITH THE EVOLUTION OF AN UPPER LOW
POTENTIALLY DROPPING SOUTHWARD OUT OF THE GULF OF ALASKA LATE NEXT
WEEK. MODELS ARE ALSO SHOWING A WIDE RANGE OF SOLUTIONS EARLIER
IN THE FORECAST PERIOD WITH THE DEVELOPMENT OF A POTENTIAL
TROPICAL SYSTEM IN THE GULF OF MEXICO EARLY NEXT WEEK. THE CMC,
GFS, AND EVEN THE LATEST 06Z GEFS MEAN TRACK A SYSTEM TOWARDS THE
CENTRAL GULF COAST/FLORIDA PANHANDLE ON TUESDAY, WHILE THE UKMET,
ECMWF, AND ECMWF ENSEMBLE MEAN BRING A SYSTEM WESTWARD TOWARDS
EASTERN MEXICO/SOUTH TEXAS. THE GEFS AND ECMWF INDIVIDUAL
ENSEMBLE MEMBERS EACH CLUSTERED AROUND THEIR DETERMINISTIC RUNS,
SUGGESTING BOTH THE GFS AND ECMWF ARE WITHIN THE RANGE OF POSSIBLE
SOLUTIONS.
THE WPC MEDIUM RANGE FORECAST STARTED WITH A BLEND BETWEEN
DETERMINISTIC AND ENSEMBLE MEAN GUIDANCE, BUT THEN RELIED MORE
HEAVILY ON THE GEFS/ECMWF ENSEMBLE MEANS BY DAY 6-7
(FRIDAY-SATURDAY) IN ORDER TO ACCOUNT FOR THE UNCERTAINTY WITH
FLOW OVER THE NORTHWESTERN U.S. LATE NEXT WEEK. ALSO, THE
FORECAST WAS MANUALLY ADJUSTED TOWARDS THE ECWMF/ECWMF ENSEMBLE
MEAN SOLUTION OVER THE GULF OF MEXICO EARLY IN THE FORECAST PERIOD
SINCE IT MATCHED BETTER WITH CONTINUITY. HOWEVER, ADDITIONAL
MODIFICATIONS MAY BE NEEDED AFTER THE 17Z WPC/NHC TROPICAL
COORDINATION CALL.
...WEATHER HIGHLIGHTS...
CONSECUTIVE DAYS OF RECORD BREAKING HEAT ARE EXPECTED BENEATH THE
STRONG UPPER RIDGE PARKED OVER CALIFORNIA AND THE DESSERT
SOUTHWEST THROUGH THE MIDDLE OF NEXT WEEK, WITH DAYTIME
TEMPERATURES POSSIBLY EXCEEDING THE 120 DEGREE MARK IN SOME
LOCATIONS. HEAVY RAINFALL COULD THREATEN THE GULF COAST STATES,
BUT THE TIMING, LOCATION, AND MAGNITUDE OF THE EVENT STILL HINGES
ON THE VERY UNCERTAIN FORECAST OF A DISTURBANCE LIFTING OUT OF THE
YUCATAN (PLEASE REFER TO THE NATIONAL HURRICANE CENTER FOR THE
LATEST INFORMATION). TO THE NORTH...DAILY ROUNDS OF CONVECTION
WITH PERHAPS SOME NOCTURNAL MESOSCALE COMPLEXES WILL BE POSSIBLE
OVER THE UPPER MIDWEST...MIDDLE MISSISSIPPI VALLEY...AND OHIO
VALLEY.

What are the early gut feelings that you guys are having. Understanding there's a lot of uncertainly, some of you, I'be been talking with since Rita, and your early gut feelings are good starting point for me. Happy Father's Day all.

Saturday afternoon Update from Jeff:
NHC has raised the chances for tropical cyclone development to 80% and designated the area of low pressure in the western Caribbean Sea as 93L.
Surface observations and high resolution GOES 16 images show a surface low has formed over the Gulf of Honduras with surface pressures having fallen from 1012mb yesterday to around 1009mb this morning. Deep convection has developed to the north and east of this broad surface reflection and the surface low is moving NNW around 5-10mph. Since the National Hurricane Center has now tagged a surface circulation model guidance is being run on the system with a fixed 1009mb center. This might help reduce the very large guidance spread in track solutions across the Gulf of Mexico. Looking at some of the early runs coming in of the ensemble members might suggest the western track solution is preferred.
Note: USAF mission planned for Monday is now being scheduled to launch on Sunday and into the western Caribbean Sea to determine if a tropical depression has formed. Expect additional multiple missions into the Gulf of Mexico next week as the system lifts NW into the SC Gulf of Mexico.
Also NHC has tasked a possible USAF mission into the Atlantic wave east of Windward Islands for Monday if needed
Residents along the US Gulf coast should closely monitor the progress of this system as it appears likely that a tropical storm will be in the Gulf of Mexico next week.

The 12Z ECMWF suggest 93L will develop and head toward the NE Mexico/S Texas Border bringing copious rainfall across the entire Texas Coast.

The afternoon Updated Weather Prediction Center Day 3 through 7 Surface Charts are now available. Looks like the WPC/NHC Coordination call has brought some changes that may have some potential rainfall and higher tidal impacts across Coastal Texas into Louisiana.
