A COLD FRONT IS PUSHING SOUTH ACROSS TEXAS AND NORTH LOUISIANA THIS
AFTERNOON. SEVERE STORMS HAVE DEVELOPED ACROSS NORTHEAST TEXAS,
NORTH LA, AND SOUTHERN ARKANSAS AS THE FRONT AND ASSOCIATED UPPER
DISTURBANCE INTERACTS WITH THE WARM AND UNSTABLE AIR MASS.

SOUTHBOUND BEFORE GRADUALLY STALLING ALONG THE COAST EARLY TOMORROW.
MOISTURE WILL CONTINUE STREAM AHEAD OF THE BOUNDARY WITH PWATS
REACHING TO AROUND 2" WHICH IS AROUND THE MAX OBSERVED FOR THE DATE.
SHEAR IS FORECAST TO BE WEAK, HOWEVER LAPSE RATES ABOVE THE
WEAKENING CAP ARE SUBSTANTIAL ENOUGH TO PRODUCE SEVERE STORMS WITH
LARGE HAIL. A LOW END TORNADO CAN NOT BE RULED OUT, BUT HAIL, GUSTY
WINDS, AND VERY HEAVY RAIN ARE THE MAIN THREATS THROUGH LATE TONIGHT.

APRIL. HEAVY/EXCESSIVE RAIN IS AGAIN POSSIBLE FRIDAY.
FORECAST RAIN AMOUNTS THROUGH THE NEXT 72 HOURS ARE GENERALLY
BETWEEN 1.5 TO 4.5 INCHES, HOWEVER SOME LOCATIONS MAY RECEIVE
AROUND 6" OVER THE 3 DAYS. HIGHER TOTALS ARE FORECAST FROM
INTERIOR SE TX THROUGH CEN LA WITH THE LOWER AMOUNTS ALONG THE
COAST. THE EVENT MAY PUT A DENT IN THE DROUGHT WITH RAINFALL
DEFICITS FOR THE YEAR ROUGHLY RANGING FROM 4 TO 8".
A COOLER AIR MASS WILL ADVECT IN DURING FRIDAY WITH COOLER WEATHER
EXPECTED TO REMAIN IN PLACE THROUGH THE WEEKEND. THE RIDGE WILL
SHIFT EAST ACROSS THE GULF COAST SUNDAY WITH AN ONSHORE FLOW
