SOUTHEASTERN PANHANDLE IN THE FORM OF THUNDERSTORMS. STEEPENING
LAPSE RATES...STRONGLY SHEARED PROFILES...AND IMPRESSIVE OMEGA
VALUES WILL CONTRIBUTE TO STORMS DEVELOPING ALONG A PACIFIC
FRONT/DRYLINE. KEPT CHANCES PULLED WEST ACROSS A GOOD CHUNK OF THE
ROLLING PLAINS WITH INITIALLY BACKED SURFACE WINDS AHEAD OF THE
DEEPENING SURFACE LOW. A FEW STORMS MAY PRODUCE SOME ISOLATED LARGE

OF CAPE. FARTHER NORTHWEST...SNOW WILL BEGIN TO DEVELOP AND
OVERSPREAD THE AREA. TEMPERATURES WILL FALL BELOW FREEZING FROM
NORTHWEST TO SOUTHEAST...WITH AREAS NORTH AND WEST OF A MEMPHIS TO
JUSTICEBURG LINE SEEING ALL SNOW BY MIDNIGHT. LOCATIONS SOUTH AND

TRAVERSES THE AREA. THIS LOW LOOKS TO CUT THROUGH THE SOUTH AND
ROLLING PLAINS...BRINGING HEAVY SNOW AT TIMES ON ITS NORTHWEST SIDE
IN VICINITY OF THE DEFORMATION ZONE. ISENTROPIC ANALYSIS SHOWS
ABUNDANT LIFT HERE WHERE A TROWAL AXIS WILL WRAP AROUND THE LOW
ENCOMPASSING THE EXTREME SOUTHERN PANHANDLE AND NORTHERN/CENTRAL
SOUTH/ROLLING PLAINS. IN ADDITION...EXTREMELY IMPRESSIVE 12 HOUR H50

OF 60 MPH AT TIMES. STORM TOTAL SNOWFALL AMOUNTS WILL RANGE FROM 6
INCHES AND ABOVE ACROSS THE EXTREME SOUTHERN PANHANDLE...TO 3 TO 6
INCHES ACROSS THE NORTHERN TO CENTRAL SOUTH AND ROLLING PLAINS.

THE MORE SOUTHERN TRACK ALSO SEEMS TO WARRANT AN ADVISORY FOR YOAKUM

So rain for our area tonight or is it all North and East? Is there a thread for just local weather and forecasts?

Excellent point. Unless you read this thread carefully you'd think the Houston/Galveston area was in for a major winter storm, not just the possibility of maybe a strong thunderstorm or two, wind, and cooler temps.
This is the KHOU weather board.

At the same time the board has branched off to a much larger community than before. We have members from Oklahoma, Arkansas, Louisiana and all places in between.

I'm more concerned about the winds after the front comes through and the red-flag warning. What kind of damage could we see out of that? Anyone have ideas?

power outages might be a concern with high winds

this site has links for all states http://vielmetti.typepad.com/vacuum/201 ... -maps.html

locally of course, here's centerpoint http://gis.centerpointenergy.com/outage ... index.html they even have a NexRad layer available for their map, but it's static
Paul Robison

Does NOAA expect winds over 60mph in our area? Or will 40 mph winds be enough to put most of the area in the dark?

Since our weather forum is branching out to a much wider audience, which, by the way, I think is a huge compliment to the amazing wealth of knowledge provided by our members - I think it would be beneficial to either break the forum into regional sections, or at least start multiple monthly threads for the various areas referenced. It gets a little difficult to find out what's going on in Houston when I'm mostly seeing posts about north Texas, and have to skim through so many posts to find out what the weather is going to do in HGX. That's just my 2 cents though.

That's a good idea to split the topics or forum to different regions. Makes it easier to find the posts you want.

Please split the threads. The discussions should focus on the KHOU region unless the weather far to the north will have a critical and direct impact on the Houston region.

With our current platform we can certainly accomplish what has been suggested. As we continue to grow and our membership and viewers of our weather community expands, we will never forget our 'roots' as a SE Texas based weather board that a Houston CBS affiliate television station funds and supports our efforts. We'll work on a solution that will provide the best of a ever growing Regional Weather Community as well as focus attention to our local weather as we do in providing Jeff's e-mail updates and major weather events that extend beyond our Region as we do in our Hurricane Central area as well as the in depth coverage of Super Storm Sandy. With growth comes some growing pains. And in the grand scheme of things, that is a positive problem not a negative. We have been working behind the scene for months to make improvements and upgrades for the expansion of what once was a little local weather community. Together we have built a weather board that we all can be proud of. Our weather community is now monitored by major media outlets from Coast to Coast. That is direct reflection on the quality of information from our knowledgeable members and the contributions our Pro Mets add that lends credibility to this great weather community. After all, we are one of the longest lasting weather boards on the web dating back to 2001.

To make it simple, just have one thread about weather outside of Houston that could cover discussion about north TX and all 49 other states and then the other just Houston locally. I don't want this forum to turn into a storm2k page. There is so many pages and topics each day it can drive me crazy. Just my two cents. But honestly, what we have going on now doesn't bother me.

Sorry for trolling, but I do want to know this:
Could tomorrow's expected near-40mph wind gusts produce damage similar to hurricane irene?

NOTE from the washington post:

As Hurricane Irene bears down on the region, the National Weather Service forecasts sustained winds of 30 to 40 mph in the District and the suburbs Saturday night into Sunday, with gusts up to 50 mph. Ocean City can expect much more bluster — sustained wind up to 90 mph and gusts even faster.

Just how much damage will all this blowing cause?

At 20 mph, trees will sway and leaves may strip off.

At 30 mph, dead branches can fall. If you’re daring — or dumb — enough to walk outside, prepare to grab one of those swaying trees to keep upright. Lawn furniture will blow around unless it’s heavy or well-secured.

But stuff doesn’t really start to fly until the wind blows even harder.

At 40 mph, branches start to rip off trees, even “well-secured branches,” said James B. Elsner, a geography professor at Florida State University who studies hurricanes.

Um, no. It will be a breezy day around here, but nothing that we haven't seen a couple of times each winter after a strong front.

Nothing close to Irene will happen or anything to that intensity. Just some stronger than normal winds.

And of course, the thin line of storms that looked encouraging about an hour ago has now fallen apart to nothing but sprinkles and continuing to lose its punch as it approaches central TX. Looks like we'll get dry slotted again Portastorm! :cry:
