AREA FORECAST DISCUSSION

417 PM CDT SAT APR 18 2009

.DISCUSSION...
VERY INTERESTING SFC FEATURE WITH ROTATION IN CHAMBERS LOOKS TO
MOVE INTO JEFFERSON AFTER 5 PM WILL MONITOR THIS STORM CLOSELY.

NEARLY STATIONARY UPPER LVL LOW SPINNING OVER SE COLORADO HAS
KICKED OUT ANOTHER IN A SERIES OF SHRTWVS THAT IS CURRENTLY
TRAVERSING COASTAL TEXAS. SFC TROF IS PROVIDING THE FOCUS FOR
TSTM DEVELOPMENT WITH THE LOW LVL JET DRAGGING MOISTURE INTO SE
TX AND SRN LA. PRECIP WATER RUNNING ABOUT 1.8 INCHES. AT THIS
TIME WITH CAPES AT 1000J/KG AND HEL OF 223 M2/S2. THIS SFC
BOUNDARY IS PROGRESSING SLOWLY ALLOWING STORMS TO TRAIN ACROSS SE
TX WITH RAINFALL TOTALS IN EXCESS OF 1 TO 2 INCHES IN TYLER...
JASPER... AND HARDIN COUNTIES. A STRONGER STORM IS PRODUCING
RAINFALL TOTALS FROM 3 TO 5 INCHES IN CHAMBERS COUNTY...THIS STORM
IS MOVING INTO JEFFERSON COUNTY AT THIS TIME AND A FFW HAS BEEN
ISSUED.

STORMS TONIGHT WILL CONTINUE A SLOW MARCH EASTWARD WITH TORRENTIAL
RAINFALL EXPECTED OVER PORTIONS OF SE TX AND SW LA. A FLASH FLOOD
WATCH FOR THIS REGION WILL CONTINUE UNTIL MIDNIGHT. A TORNADO
WATCH IS ALSO IN EFFECT AS SHEAR OVER SE TX AND SRN LOUISIANA WILL
ALSO SUPPORT TORNADO DEVELOPMENT THIS EVENING. STORMS ENDING
OVER SE TX AND EXTREME SW LA AROUND MIDNIGHT AND AFTER MIDNIGHT
FOR S-CNTRL LA.

UPPER LVL LOW LOOKS TO GET A KICK OFF TO THE EAST AS NRN JET DROPS
DOWN INTO SOUTHERN PLAINS STATES TOMORROW. THIS WILL PUSH THROUGH
A FRONTAL SYSTEM FINALLY DRYING OUT SE TX TMRW MRNG AND SRN LA BY
THE AFTERNOON HOURS.

What is this going to mean for those of us to the east? Stronger storms? Tornados?

Anyone?

I gave her my opinion, but what do I know?


It's been raining cats & dogs for many hours here. Moderate to heavy intensity... back and forth, but always steady rain with no breaks. No crazy totals like KatDaddy and not even in the Allison family (Allison caused major flooding around here), but still... a LOT of rain!

But hey... it's letting up in the Houston area, so at least we know there's an end in sight.

Sorry.

My part of Texas isn't in a drought, so we didn't really need it. We still had some leftover standing water and/or mushy grounds in various spots from last weekend's storms, or the ones before that. Fortunately, a lot of the areas in Texas that really did need the rain, got some.... maybe too much. It's always feast or famine around here.

Geezum.... look at all the locations for this flash flood warning.

And I thought my eyes were bugging a few hours ago. Jeez! It's pitch black here in Bear Creek.

[edit] Looking at radar trends, I'm getting extremely worried about training setting up over western Harris county. Can someone tell me I'm just over-reacting?

It is not an over-reaction. This rain stretches all the way to S of SA. It has now set up training from what I see on the radar.and the urban and small stream flood advisory is definitely warranted. I am preparing to go further into skywarn mode and may have to begin reporting from my area. It has been pouring at our house for the last 20-30 minutes with no let up. What I was concerned was going to happen with the massively unstable air mass is apparently beginning to happen and we may be looking at a massive flood event over much of the Houston metro and SE TX area. Please everyone in the Houston metro/SE TX area stay home. The streets will probably begin to fill quickly and become impassable in many areas unless this lets up soon and radar does not indicate that at this time.

Edit: 12.49pm-Our streets are now becoming impassable. The water is higher than I have seen it in a long time here.

Edit: 1:15 pm-Cars flooded out in our streets and the water is higher than every time except one(Allison)that I have seen in the 22 years we have lived in this house. It is still pouring and when I checked the gauge 20 minutes ago we were already at 3.5" and that was probably low due to the location of the gauge. Definitely a major flood event unfolding now in the Houston area. Everyone please be safe. I have already reported to NWS and we were just issued a Flash flood warning for Harris and Montgomery Counties.

Edit: 1:36 pm-Just emptied 4" out of the rain gauge and it is still raining though it has let up some. Streets still impassable. Radar returns to the SW concern me, especially if those move N of or along I-10(not that I'm not concerned for other areas, but areas N of I-10 have been POUNDED already).

Final total for me today after the rains stopped was 4.6". With the rains from yesterday(1.7") that makes 6.3" for the two days!!! No more drought for us!
Unfortunately those radar returns to my SW have ended up causing extensive flooding with water in homes in the SE portions of the Houston metro area(Clear Creek area, etc.). I can not even imagine what it would be like in my area if we had received those rains on top of the 4" from earlier today!
SG are you ok over in your area? Rockets are kicking butt and taking no names so far!!! GO ROCKETS!!

[KatDaddy]

It was on an Allison level. Amazing rainfall which maxed out at 15.57" per hour.

Airport recorded 6.07" of rain since 3pm today. Friday night total was 1.49". So we got a total of 7.56" in about 24 hours.

Criminal, a drunk driver talking on a cell phone in a car overloaded with children drove off the road and down an embankment.

Airport recorded 6.07" of rain since 3pm today. Friday night total was 1.49". So we got a total of 7.56" in about 24 hours.

Where did you see that? Can't be Lafayette as they recorded 2.22" of rain yesterday according to the official climate data report on the Lake Charles NWS site. Storm totals are in the 3"-4" range for Lafayette and the yards are loving it!

I added up everything in the 6 hour column (3 day history) that they had listed which seems to have changed today. At one time last night they had us at 2-3" in just one hour.

[JenBayles]

We flooded again in Bear Creek. Cars and trucks flooded in the street and a little water in some houses. We were trapped until about 4:30. On top of that, my mother has very bad and complex health issues and I couldn't reach her. Once the water cleared we were off the ER at Memorial City where she was admitted for a gastric bleed and a hemoglobin of 6 - less than half of normal. Long story that I don't care to get into, but it's not looking good.

I'll post flood pics as soon as I can. I'm so sick of flooding here in Bear Creek, and NONE of our County, State or Federal officials will do a dam thing about it. They just keep permitting more and more development in our watershed. After all, can't shoot the golden devlopment-tax goose...
