Evening Radar Update

20130509-213919.jpg

Many parts of the state are dealing with storms this Thursday night. The most severe area is the Hill Country where a complex of storms is diving southeast. We have already seen multiple tornado warnings but no confirmations of tornadoes. There have been lots of hail, golf ball and bigger. The area from Austin south to San Antonio is untouched, meaning there is energy in the atmosphere to keep the severe threat high overnight. Hail and winds would be the main threats but cannot rule out an isolated tornado.

In southeast Texas, strong storms continue from Houston to deep east Texas. This activity has been isolated severe but are producing flooding rain and lots of lightning. Activity will be pushing east towards Louisiana but could see more storms by morning in Houston and along the coast.

Finally, in the Panhandle, storms continue to organize into a complex or MCS. Severe threat is low but this complex will be watched as it dives southeast towards northwest Texas and the Big Country.

Today’s Weather – Tuesday, April 30th

Good morning and happy Tuesday!   We’ve got spotty showers are out between Sweetwater and Abilene this morning.  An upper level low is still spinning around over the coastal regions with a large area of rain off the coast of Galveston this morning and some spotty showers along the coast near Victoria.  This low will continue to move east towards Louisiana during the day today and should exit the region overnight.  Expecting another round of showers and a few thunderstorms to develop along the coastal and southeast regions this afternoon, especially during peak daytime heating.  Local forecasters are not confident in the exact placement and timing of storms this afternoon as this will depend on the eventual track and speed of the low.  Current hi-resolution forecast models show most of the rain and storm activity to remain just offshore, but a few other models are bringing the chance of rain onto the coast and into southeastern Texas later this afternoon, so it’s worth mentioning that it could happen.  And if it does happen, localized flooding could be an issue.  Another area expecting potential storm activity later this afternoon is the southern panhandle region.  There is a chance for storm development along the dryline later this afternoon during peak daytime heating, mainly along and east of the I-27/US87 corridor and south towards the Midland/Odessa areas.  Widespread severe is not expected at this time, but a few of the stronger cells that develop could contain very gusty outflow winds, especially as they begin to decay and collapse around sunset.  Elsewhere, just very warm with highs in the upper 70′s across eastern Texas, mid to upper 80′s across central Texas, and highs into the mid 90′s across the western portions of the state.  We’re still on track for an unseasonably strong cold front to move through the state beginning tomorrow afternoon and reaching the coastal regions by Thursday.  We’ll have more updates on that, plus the rain/storm potential accompanying this front, later today!

Severe T-Storm Watch for extreme Northeast/East Texas

The Storm Prediction Center has issued a Severe Thunderstorm Watch until 10 PM. This watch includes extreme Northeast and East Texas, or the two-tiers of counties closest to Arkansas and Louisiana. The watch runs along and east of Clarksville, Mount Pleasant, Longview, Henderson, and Nacogdoches. Large hail will be the main threat with some hail possibly larger than two inches. Here are a list of counties included in the watch. Further west, a strong cap should prevent any thunderstorms from developing this afternoon.

TEXAS COUNTIES INCLUDED ARE

     
     BOWIE                CAMP                CASS

Saturday Morning Update – Storms/Rain/Strong Cold Front Tonight

Good morning!  At the time of this writing, we had quite an eventful morning across southern portions of the DFW metro area with severe storms and copious amounts of hail.  These storms have now moved off into northeast Texas and are, so far, remaining below severe criteria.  The Storm Prediction Center has most of east central Texas under a Standard Risk for severe weather today; however, they do not have high confidence in the overall risk and location of any severe weather potential.  Forecast model guidance has not performed very well with handling of the current atmospheric setup and position/movement of the current frontal boundary, so expect some slight changes in the risk areas as the day progresses.  The main area of concern for the rest of this morning will be the southern end of the current storm complex where the aforementioned storms have already produced hail and other atmospheric mischief.   This will continue to push eastward and on into Louisiana over the next several hours.

For tonight, an upper level disturbance will approach pushing a strong cold front through north Texas overnight and through the remainder of the state by Sunday afternoon.  Additional storm development along the frontal boundary later today is possible, so we’ll be monitoring that and will have further updates for you at later this afternoon.  Snow/blowing snow are likely up in the northern Texas panhandle this afternoon and evening as well.  Winter Weather Advisories have already been posted for this region in effect from 3pm today until early Sunday morning.  David Drummond will have additional details out later today for the panhandle region.

Pineland, TX Tornado Rated EF-1 – First Fatal Texas Tornado since 2007

0355The National Weather Service in Shreveport has completed their survey of damage near Pineland, TX. They have confirmed that an EF-1 tornado with winds up to 105 MPH touched down. This tornado traveled 4.5 miles and was on the ground for nine minutes. Sadly, a 74 year old woman was killed when her mobile home was rolled and then demolished by falling trees. This was a rare case where no severe thunderstorm or tornado warnings were in effect. After reviewing radar data, I can confirm that this storm did not show any strong indications of producing a tornado. Research will be done into this event to find out what went wrong in the warning process. We don’t often see fatal tornadoes go without warning, but this one really did strike without warning. This is the first fatality to occur from a tornado in Texas since April 24, 2007.

Here is the storm survey from the National Weather Service in Shreveport, Louisiana.
