.PREV DISCUSSION... /ISSUED 334 PM CDT THU APR 17 2014/

DISCUSSION...
RAIN IS FINALLY BEGINNING TO FORM OVER PARTS OF WESTERN AND
NORTHERN OKLAHOMA...ALTHOUGH INTENSITY IS STILL VERY LIGHT. LOW
RAIN CHANCES WILL CONTINUE OVERNIGHT OVER PARTS OF CENTRAL AND
EASTERN OKLAHOMA...AND ADJACENT PARTS OF NORTH TEXAS...BUT AGAIN
AMOUNTS ARE EXPECTED TO BE QUITE LIGHT.

AFTER A QUIET DAY TOMORROW...RAIN CHANCES WILL RESUME SATURDAY AS
WARM AND MOIST AIR SURGES NORTH AGAIN. RAIN/THUNDERSTORMS ARE
LIKELY TO CONTINUE OFF AND ON THROUGH MONDAY AS A SERIES OF WAVES
ALOFT DRIFT OVER THE SOUTHERN PLAINS. A FEW OF THE STORMS MAY BE
STRONG OR SEVERE ON SUNDAY AFTERNOON AND EVENING...BUT THE OVERALL
POTENTIAL APPEARS LOW...AND SIGNIFICANT ORGANIZATION IS
IMPROBABLE.

ANOTHER STORM SYSTEM SHOULD ARRIVE WEDNESDAY AND
THURSDAY...BRINGING ANOTHER CHANCE FOR RAIN AND STORMS. THE SETUP
ON THURSDAY MAY SUPPORT SEVERE STORMS...BUT IMPORTANT MODEL
DIFFERENCES GREATLY REDUCE CONFIDENCE IN THIS PART OF THE
FORECAST.

TEMPERATURES WILL REMAIN NEAR OR ABOVE THE SEASONAL AVERAGE FOR
MOST OF THE PERIOD.

&&

.OUN WATCHES/WARNINGS/ADVISORIES...
OK...NONE.
TX...NONE.
