Morning complex of severe storms brings damage to East Texas

October 6th, 2014 at 11:17 am by under Weather

10-6 SVR

Early Monday morning, individual severe thunderstorms moved from Oklahoma into NE Texas, merging into a complex of severe thunderstorms exhibiting a large “bow echo”.

A bow echo is when a line of thunderstorms is pushed outward into a bow shape, and indicates the presence of strong, damaging wind gusts in the storms.

Strong thunderstorms winds toppled numerous trees in rural East Texas.

West Antarctica’s meltdown weakens Earth’s gravity

October 4th, 2014 at 9:41 pm by under Weather

West Antarctica’s incredible weight loss can be felt from space, a new study reports.

So much ice has disappeared from West Antarctica in recent years that Earth’s gravity is now weaker there, researchers reported in the Aug. 28 issue of the journal Geophysical Research Letters.

Earth’s gravity fluctuates in small ways that are caused by changes in mass. When hefty ice sheets melt, there is less ice and thus less gravitational force pulling in that area.

This graphic shows the changes in Earth’s gravity field caused by West Antarctic ice loss, based on data from the GOCE satellites. The satellites ended their mission in 2013 when the spacecraft ran out of fuel, as planned, and broke apart during atmospheric re-entry.

Severe Weather Potential Thursday Night

October 1st, 2014 at 8:25 am by under Weather

spc

This is the latest Categorical Outlook map for severe weather from the Storm Prediction Center in Norman, OK.  They show the KXAN viewing area inside of the tail end of the yellow “slight risk” area for severe weather.  This means the potential for storms including gusty winds large hail, and heavy downpours will be around Thursday night.  Here is the latest write-up from the National Weather service:

SPC AC 010424
DAY 2 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
1124 PM CDT TUE SEP 30 2014

   VALID 021200Z - 031200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS FROM THE MIDWEST TO CNTRL TX...

   ...SUMMARY...
   BAND OF THUNDERSTORMS SHOULD FORM ALONG COLD FRONT AS IT PROGRESSES
   ACROSS THE PLAINS INTO THE MISSISSIPPI VALLEY.  DAMAGING WIND GUSTS
   ARE THE PRIMARY SEVERE THREAT WITH THE STRONGEST STORMS.

   ...MIDWEST TO CNTRL TX...

   LOW LATITUDE SHORT-WAVE TROUGH WILL EJECT ACROSS THE SRN
   ROCKIES/HIGH PLAINS EARLY IN THE PERIOD BEFORE EJECTING RAPIDLY NEWD
   INTO THE LOWER OH VALLEY AFTER MIDNIGHT.  PRIMARY FEATURE
   RESPONSIBLE FOR THIS RAPID EJECTION IS AN INTENSIFYING SPEED MAX
   THAT WILL DIG INTO THE CNTRL PLAINS BY 03/12Z.  THIS SECONDARY
   FEATURE SHOULD AID DEEPENING CYCLONE/SHARPENING FRONTAL BOUNDARY
   OVER THE UPPER GREAT LAKES LATE.

   ALTHOUGH FRONTAL INTENSIFICATION IS NOT EXPECTED UNTIL LATE IN THE
   PERIOD...CONVECTION IS EXPECTED TO DEVELOP ALONG PROGRESSIVE
   BOUNDARY BEGINNING FAIRLY EARLY IN THE PERIOD.  LATEST MODEL
   GUIDANCE SUGGEST AMPLE BOUNDARY LAYER MOISTURE WILL ADVANCE AS FAR
   NORTH AS NRN IL BY LATE AFTERNOON WITH PW VALUES AOA 1.5 INCHES. 
   WHAT LITTLE CINH IS OBSERVED AT 12Z AHEAD OF THE FRONT WILL DIMINISH
   BY 17-18Z SUCH THAT THUNDERSTORMS SHOULD READILY DEVELOP ALONG WIND
   SHIFT ACROSS ERN KS/OK.  THIS ACTIVITY SHOULD MATURE INTO A
   EXTENSIVE SQUALL LINE STRETCHING FROM THE MID MS VALLEY...SWWD INTO
   NERN TX BY LATE AFTERNOON.  GREATEST BUOYANCY IS EXPECTED TO RESIDE
   FROM THE OZARK PLATEAU SWWD INTO TX AND HAIL IS MOST LIKELY ALONG
   THIS PORTION OF THE SQUALL LINE.  MEAN SWLY WIND WILL BE ON THE
   ORDER OF 30-35KT...MORE THAN ADEQUATE FOR PROGRESSIVE SQUALL LINE
   THAT SHOULD ADVANCE TOWARD THE MS RIVER DURING THE EVENING HOURS. 
   WHILE DEEP LAYER SHEAR IS MORE THAN ADEQUATE FOR DEEP
   ROTATION...STORM MODE FAVORS LINEAR DEVELOPMENT AND DAMAGING WINDS
   ARE THE PRIMARY SEVERE THREAT.
