2/1/2006 NOW: South East TX

[Bill Tabor]

Heading out. Late as usual. :lol:

 

[Alex Lamers]

First severe weather warning of the afternoon in Fayette County Texas from the San Antonio office. Penny sized hail is the threat. Does not appear to be rotating or well organized yet but I could see a marginally severe hail threat.

 

[Bill Tabor]

So far looks like the wave I was depending on toward VCT is late. Probably won't go til near HOU and near dark, or after dark.

Watch out LA Coast...interesting cell offshore. :!:

THE NATIONAL WEATHER SERVICE IN LAKE CHARLES HAS ISSUED A

* SPECIAL MARINE WARNING FOR...
COASTAL WATERS FROM INTRACOASTAL CITY TO CAMERON LA OUT 20 NM OVER
GULF OF MEXICO WATERS

* UNTIL 945 PM CST

* AT 839 PM CST...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A
THUNDERSTORM...PRODUCING A WATERSPOUT OVER COASTAL WATERS FROM
INTRACOASTAL CITY TO CAMERON LA OUT 20 NM...OR ABOUT 20 MILES SOUTH
OF CAMERON...MOVING NORTHEAST AT 30 MPH.

Good rotation through the cuts that I've seen. Mesocyclone nomogram indicates a strong mesocyclone on that cell at the 1.5º slice and a decent low-level rotation signature...even though the 0.5º slice is about 2250 feet in the air at this distance from the radar. Base velocity also indicates some >71 knot magnitude pixels...so there should be some severe weather from this cell. Does not appear to be producing much in the way of hail though.

I have the rotation pegged to get to Grand Chenier by 9:20 PM. Good news is that thats the only city on its pathcast through Cameron County, so rural area could be a benefit if a tornado touches down.

Given the WW and the SMW for waterspouts, would not be surprised to see a TOR here.

Yippee! Looks like I was right. The stronger MESO earlier has since weakened and broadened, making tornado potential much less likely. We shall see if it reorganizes any but looks like mainly a wind damage threat for now. 2 other warnings out...looks like it was a "nighttime show" after all, if you want to call it a show at all. :roll:

Cool. Finally some storms start. Looks like the other watch pretty well busted. I can't blame SPC though as I had the same forecast. Turns out my fear that the shortwave wouldn't show up in time came to pass. It kept slowing in later runs. I was hoping it would come through earlier during the afternoon when the low and cold front were still further west to assist in breaking the cap. I don't like to chase HOU metro and especially wouldn't want to at night.

SPC updated their page and the WCM from NWS Norman mention this too:
The Enhanced F-scale will be implemented February 2007.

There are very few jobs in meteorology.
