.PREV DISCUSSION... /ISSUED 317 PM CDT WED APR 15 2015/

SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...
UPPER AIR ANALYSIS THIS MORNING SHOWED A LOW OVER THE GREAT BASIN
WITH THE TROUGH ASSOCIATED WITH IT BROADENED ACROSS THE SOUTHWEST.
THIS HAS ESSENTIALLY ZONAL FLOW OVER TEXAS. AT THE SURFACE HIGH
PRESSURE WAS CENTERED OVER EAST TEXAS. THE PRESSURE GRADIENT OVER
OUR EASTERN COUNTIES WAS LOOSE AND WINDS WERE LIGHT. OVER THE
WESTERN HALF IT WAS TIGHTER AND WINDS WERE FROM THE SOUTH. DEW
POINTS HAVE INCREASED BY AROUND FIVE DEGREES. THE UPPER LOW IS
EXPECTED TO DROP TO THE SOUTH BEFORE EJECTING TO THE EAST. THIS
WILL TURN THE UPPER FLOW TO SOUTHWEST. AT THE SAME TIME LOW LEVEL
FLOW WILL BECOME BETTER ESTABLISHED FROM THE SOUTHEAST AND
MOISTURE WILL CONTINUE TO INCREASE. THERE IS A CHANCE FOR
THUNDERSTORMS TONIGHT...BUT BETTER CHANCES TOMORROW. INSTABILITY
WILL INCREASE DURING THE DAY THURSDAY WITH MUCAPE RANGING FROM
2000 TO 3500 J/KG. SPC HAS US IN A SLIGHT RISK FOR SEVERE
THUNDERSTORMS. AFTERNOON AND EVENING LOOK TO BE THE BEST
TIMEFRAME. MOST LIKELY THREAT IS LARGE HAIL AND DAMAGING WINDS.
THE TORNADO THREAT IS LOW...BUT NOT ZERO.

LONG TERM (FRIDAY THROUGH WEDNESDAY)...
THE UPPER LOW WILL MOVE SLOWLY FROM THE SOUTHWEST TO THE CENTRAL
PLAINS. THIS WILL MEAN CONTINUING CHANCES FOR THUNDERSTORMS FRIDAY
AND SATURDAY. INSTABILITY WILL CONTINUE TO BE SIGNIFICANT FRIDAY
AND SPC HAS US IN THE SLIGHT RISK ON DAY THREE...BUT THIS HAS NOT
BEEN UPDATED DURING THE DAY. THINK THE SEVERE RISK IS LESS FRIDAY
THAN THURSDAY. PW FRIDAY WILL BE ABOVE 1.5 INCHES ACROSS THE
SOUTHERN HALF OF THE CWA...SO THERE MAY BE A LOCALLY HEAVY RAIN
RISK. BY SUNDAY THE UPPER LEVEL TROUGH WILL MOVE TO THE EAST OF
THE REGION AND THIS WILL BRING AN END TO RAIN CHANCES. THEN WEAK
RIDGING WILL BRING A PERIOD OF DRY WEATHER INTO THE NEW WEEK.
