K, but if it were to remain a weak storm and move swiftly through, it would really help with the rainfall deficits this year... Parts of SE TX and LA could really use some rain, and a weak TS that doesn't overstay its welcome is a nice cure.

HGX thoughts:

FCST INTO THE MID/LATER PARTS OF NEXT WEEK HINGES ON WHAT THE
TROPICAL STORM ALEX ENDS UP DOING. IT IS FCST TO MOVE OVER THE
YUCATAN THIS WEEKEND AND EMERGE IN THE SRN GULF LATE SUNDAY. FROM
THERE THE OFFICIAL TRACK TAKES IT TO AROUND 275 MILES SOUTH OF
MATAGORDA BAY (OR 150 MILES SE OF BROWNSVILLE) LATE WED NIGHT...WHICH
IS GENERALLY A LITTLE TO THE RIGHT OF THE LATEST 6Z GUIDANCE
SPAGHETTI PLOT. GFS IS SHOWING A BROAD 1006MB LOW IN THAT SAME
GENERAL VICINITY AT THAT TIME THEN DRIFTS IT AROUND OFF THE UPPER
TX COAST FOR A FEW DAYS. FWIW...ECMWF TAKES IT TOWARD TAMPICO WED
MORNING...NOGAPS & CANADIAN TO S TX WED/WED NT. KIND OF AN
INTERESTING UPPER PATTERN AT THAT TIME WITH A MID LEVEL HIGH OFF
BAJA...ANOTHER EXTENDING INTO THE ERN GULF...AND A THIRD ONE IN
THE PLAINS (AND THE TROPICAL SYSTEM SANDWICHED BETWEEN THEM ALL).
UNTIL ALEX MOVES BACK INTO THE GULF AND REORGANIZES AND THE UPPER
PATTERN/DOMINATING STEERING FLOW BECOMES MORE CLEAR...THE FCST FOR
SE TX WILL REMAIN HIGHLY UNCERTAIN. FOR NOW...PLAN ON NUDGING POPS
UP OFFSHORE AND CLOSER TO THE COAST NEXT WEEK AS THE OVERALL
CIRCULATION APPEARS TO BE FAIRLY LARGE.

STILL A BIT EARLY TO SAY WHAT TIDES WILL DO AS WELL BUT WOULD
ANTICIPATE A SLIGHT RISE AS AN E/ENE FETCH BEGINS SETTING UP.

0z GFDL has shifted S to Brownsville. I suspect we will see the track adjusted further to the S now that the GFDL is becoming more in line with the other models.

Rapid intensification is a possibility today given the coverage of cold convection and the appearance of numerous hot towers. From SHIPS:

Prob of RI for 25 kt RI threshold= 42% is 3.6 times the sample mean(11.8%)
Prob of RI for 30 kt RI threshold= 25% is 3.0 times the sample mean( 8.1%)
Prob of RI for 35 kt RI threshold= 2% is 0.3 times the sample mean( 5.7%)
Prob of RI for 40 kt RI threshold= 1% is 0.3 times the sample mean( 4.1%)

Good Morning everyone. I see that we have our first tropical storm of this year's hurricane season as 3:55a.m. Does it look like Tropical Storm Alex is moving west-northwest or northwest to any of you?

Alex is a very large June system. More models are coming in line with Euro which points to a NE MEX landfall. Joe Bastardi is also calling for a NE MEX landfall but did state it could be close to S TX. He believes this will become the first hurricane of the 2010 season.

I thought that dome of high pressure was predicted to siphon it a little more to the north to somewhere in between Brownsville and Houston.

The ridge over the eastern GOM would push Alex more west,....

I urge everyone to not assume that what you read today about Alex will be valid tomorrow. This storm is moving slowly, and is expected to strengthen quickly, especially after it moves into the Gulf. As conditions change over the coming days, it is every bit possible that the track moves back up the Texas Coast. We may be going to see that Mexico landfall in the end, but it is in no way set in stone...At least not yet. Everyone from Brownsville to New Orleans had better pay attention.

I went yesterday and bought my Hurricane supplies for the season. It was the right time.

Alex is looking pretty healthy for a minimal TS, and large to boot.

I'm in agreement with biggerbyte that Alex shouldn't be taken for granted.

the TCHP graphic sort of shows where the center is/was sucking up heat from the ocean, so you can use it as a reference of sorts

then there's always CIMSS, which is likely more accurate

Here's a plot of some of the better models, along with the OFCI (official interpreted) track from the NHC. Note that the only track NOT well inland in 5 days is NHC. They're WAY too slow with moving Alex on the last two days, just 1-2 kts forward speed. We have Alex inland about 120 miles south of Brownsville before noon Wednesday. Oh, and I'm fairly confident it'll be a hurricane, possibly Cat 2 or greater. Just don't see the shear to hurt it in the Gulf. And with a good 48-60 hrs over water, it could become a large and powerful hurricane. Just depends on how much the core is disrupted over the Yucatan. Such a large circulation won't be disrupted as much, though.
