FOR EXTENSIVE BANDS OF CIRRUS FROM ONGOING CONVECTION OVER W TX TO
CONTINUE TO OVERSPREAD THE REGION THROUGH THE OVERNIGHT

LA/SCNTRL AR...WHERE 05Z TEMP/DEWPOINT DEPRESSIONS ARE LOW. A SCT
CU FIELD SHOULD DEVELOP AREAWIDE BY LATE MORNING/MIDDAY WITH
DIURNAL HEATING...WITH ADDITIONAL CIRRUS SPILLING E DURING THE DAY

.PREV DISCUSSION... /ISSUED 1019 PM CDT SAT APR 19 2014/

DISCUSSION...
CIRRUS SPREADING FARTHER EAST INTO THE REGION THIS EVENING SHOULD
HELP SLOW THE TEMPERATURE FALL FOR MOST AREAS. NEVERTHELESS...STILL
SEVERAL MORE DEGREES TO GO TO REACH OVERNIGHT MINIMUMS AND EXPECT
WE WILL ACHIEVE THEM AT MOST SITES BUT DID ADJUST TEMPS JUST A BIT
OVER PARTS OF E TX WHERE CIRRUS IS MORE DENSE ATTM AND TEMPS HAVE
ONLY MANAGED TO FALL INTO THE MID TO UPPER 60S AT TYR/LFK AS OF
03Z. ALSO TWEAKED THE SKY GRIDS TO BETTER ALIGN WITH CURRENT SKY
COVER AND EWRD EXPANSION OF CIRRUS. OTHERWISE...THE GOING FORECAST
IS IN GREAT SHAPE AND NO OTHER CHANGES ARE PLANNED. UPDATED
PRODUCTS HAVE ALREADY BEEN SENT. /19/
