CURRENT ANALYSIS CONTINUES TO SHOW UPPER LEVEL TROF AXIS OVER THE
LOWER MS VALLEY. THIS...COUPLED WITH MOISTURE AND INSTABILITY
ACROSS C AND SC LA...ISO/SCT SHRA/TSRA CONTINUES OVER THIS REGION.
THE CONTINUATION OF 20-30% OF SHRA/TSRA FOR THE REMAINDER OF THE
AFTERNOON IS WARRANTED.

AFTER THE LOSS OF DAYTIME HEATING AND THE TROF AXIS MOVES FURTHER
EAST...THE SHRA/TSRA IS EXPECTED TO DIMINISH THIS EVENING. LOWS
EXPECTED RANGE IN THE MID 50S TO NEAR 60.

THE NEXT UPPER LEVEL DISTURBANCE ACROSS THE WESTERN U.S. WILL
MAINLY BYPASS OUR REGION AS HIGH PRESSURE AT THE SFC AND ALOFT
WILL HOLD FOR THE NEXT COUPLE OF DAYS. THUS...SLOWLY MODERATING
TEMPS BACK TO NORMAL WITH NO SIGNIFICANT PRECIP EXPECTED THIS
EASTER WEEKEND.

THE MIDWEST TROF DIGGING FURTHER SOUTH MON & TUE MAY ALLOW FOR A
WEAK FRONT TO MOVE THRU THE REGION MON NIGHT INTO TUE WHICH MAY
SCURRY UP ISO SHRA/TSRA. HOWEVER...THIS FRONT EXPECTED TO WASH OUT
ANYWAY WITH NO COOLING TEMPS BEHIND IT. SO...LOWS IN THE
LOWER/MID 60S AND HIGHS NEAR 80/LOWER 80S LIKELY FOR NEXT WEEK.
