.PREV DISCUSSION 403 AM CST...
TROPICAL PLUME OF MOISTURE SPREADING NORTHEAST ACROSS TEXAS THIS
MORNING WILL EVENTUALLY BRING RAIN TO THE REGION...ESPECIALLY THE
EASTERN HALF OF NORTH TEXAS THIS AFTERNOON AND TONIGHT. THE THREAT
OF SEVERE WEATHER HAS DECREASED FROM EARLIER THOUGHTS THE PAST DAY
OR TWO...AND WE FEEL THAT HEAVY RAIN WILL BE OUR BIGGEST PROBLEM
DURING THE NEXT 24 HOURS.

IN THE CWA...WE HAVE NOT HAD SIGNIFICANT RAINS THE PAST WEEK...WITH
THE EXCEPTION OF LEON AND ROBERTSON COUNTIES SUNDAY.
OTHERWISE...THERE SHOULD NOT BE A PROBLEM WITH SEVERAL INCHES OF
RAIN OVER A FEW HOURS AS THE GROUND SHOULD HANDLE IT AS WELL AS
VEGETATION SHOULD STILL ABLE TO HELP.  FOR NOW...WE WILL JUST
MENTION HEAVY RAINS POSSIBLE ALONG AND EAST OF THE I35 CORRIDOR THIS
AFTERNOON AND EVENING IN THE ZONES AND HAZARDOUS...AND NOT ISSUE A
WATCH.  THIS WILL BE MONITORED FOR UPDATES AS NEEDED.

PRECIP SHOULD END WEST TO EAST THIS EVENING AS UPPER LOW MOVES
RAPIDLY EASTWARD...GIVING US GOOD WEATHER THROUGH FRIDAY. THERE HAS
BEEN SOME VARIABILITY IN THE HANDLING OF THE SYSTEM THIS
WEEKEND...SO WE HAVE ONLY REMOVED PRECIP FROM FRIDAY AND LEFT THE
REMAINDER AS IS FOR NOW. 42
