April: Warm & Muggy To End The Month. Showers Monday?

[Andrew]

Looking at video out from Dallas a lot of residents received a lot of damage and from initial pictures it does look like a tornado is very likely. Most likely dropping down and picking back up multiple times.

The system NW of Dallas looks to be weakening slightly....

Dallas area currently:

From Jeff:

Two supercells have produced large destructive tornadoes across the Dallas/Fort Worth metroplex. Extensive damage has occurred across the SE side of the City of Dallas and in the corridor from Arlington to SE of DFW Airport. One of the tornadoes may have been up to ½ of a mile wide at times and on the ground for over 30 miles.


WFAA Footage from Helicopter via CNN of 18-wheelers being lofted in Lancaster, TX:

Look at the video that Srain just posted: WOW!!

Another update from Jeff:

SPC has issued a Tornado Watch until 1000pm for the following counties in SE TX: Houston, Trinity, Polk, San Jacinto, Walker, Madison, Grimes, and Brazos.



Air mass over SE TX has become very unstable with cap over the northern areas weakening. Cells are beginning to develop north of HWY 105 northward into NE TX ahead of strong mid level lift along leading edge of impulse over WC TX and dryline nearing I-35. While significant tornadoes have occurred this afternoon over N TX, these tornadoes are tied closely to an east/west outflow boundary which has yielded favorable low level shear for violent tornadoes in that region. While shear values are high over the entire watch area…and tornadoes are possible…the main threat appears to be focused just north of SE TX over NC and NE TX where tornadoes are ongoing…and a few long tracked violent tornadoes are possible in this part of the watch.



Further south over the southern half of SE TX capping appears to be holding for the time being, but any storms that due develop will go quickly severe. Watching cumulus towering along the dry line west of Austin for possible initiation of additional storms.

PORTION OF THE LOWER MS VALLEY...

...THERE IS A SLGT RISK OF SVR TSTMS OVER A PORTION OF THE OH
VALLEY...

...NCNTRL THROUGH NERN TX...

GREATEST TORNADO THREAT WILL PERSIST INTO THE EARLY EVENING OVER
NCNTRL AND A PORTION OF NERN TX AS DISCRETE STORMS DEVELOPING IN
WARM SECTOR MOVE NEWD AND INTERACT WITH A STATIONARY E-W ORIENTED
OUTFLOW BOUNDARY. THE 0-2 KM HODOGRAPHS ARE LOCALLY ENHANCED WHERE A
MODEST 30-35 KT LLJ INTERSECTS THIS BOUNDARY.

...NRN LA THROUGH W-CNTRL AND SWRN MS...

STORMS DEVELOPING ALONG A CONVECTIVE OUTFLOW BOUNDARY HAVE ORGANIZED
A COLD POOL AND SHOULD CONTINUE TO PROPAGATE SWD INTO A MODERATELY
UNSTABLE ENVIRONMENT. VERTICAL SHEAR IS WEAK...BUT STEEP LAPSE RATES
AND 2000-2500 J/KG MLCAPE WILL SUPPORT A THREAT OF ISOLATED DAMAGING
WIND AND HAIL. HAVE EXPANDED THE SLIGHT RISK AREA EWD TO ACCOUNT FOR
THIS DEVELOPING SCENARIO.

...OH VALLEY REGION...

THE ATMOSPHERE IS DESTABILIZING IN VICINITY OF A QUASI-STATIONARY
FRONT THAT EXTENDS ACROSS NRN IL SWWD INTO NRN MO. MEANWHILE...A
VORT MAX LOCATED OVER CNTRL MO WAS MOVING SLOWLY NEWD. STORMS WILL
LIKELY DEVELOP WITHIN THE ZONE OF FRONTAL CONVERGENCE OVER N-CNTRL
IL BY LATE AFTERNOON AS THE BOUNDARY LAYER CONTINUES TO DESTABILIZE.
OTHER STORMS MAY DEVELOP FARTHER SOUTH FROM ERN MO INTO WRN IL. WEAK
VERTICAL SHEAR WILL SUPPORT MULTICELLS...BUT STEEP LAPSE
RATES...MODERATE INSTABILITY AND SUFFICIENT BOUNDARY LAYER
TEMPERATURE-DEWPOINT SPREADS WILL PROMOTE A THREAT OF ISOLATED
DAMAGING WIND AND HAIL.

Line is really extending south. Here in College Station things are still heating up and the sun it out in full force.

Andrew, get a gr shot of the cell just E of DT Dallas. FWD reporting tightening circulation heading toward Sunnvale.

How do I get a picture to get to the format I need to upload on here? I have some awesome pics some friends that saw the tornado where they were in Dallas and posted it on Facebook and would love to share on here.
