.SHORT TERM...(TODAY THROUGH SATURDAY NIGHT)
ISSUED AT 105 AM CDT THU APR 30 2015

A SLIGHT CHANCE OF A SHOWER EXISTS TODAY...MAINLY FOR OUR EASTERN
COUNTIES...AS LOW PRESSURE DROPS SOUTH ACROSS THE MIDDLE OHIO
RIVER VALLEY. MOST PCPN WILL BE TO OUR EAST.

THE REMAINDER OF THE SHORT TERM LOOKS DRY AS TROFFING IN THE UPPER
ATMOSPHERE TRANSITIONS TO A NORTHWESTERLY FLOW ALOFT...IN RESPONSE
TO THE LOW PUSHING OFF TO THE EAST AND WEAK TELECONNECTED RIDGING
TO OUR WEST. THIS WILL LEAD TO A MINOR/GRADUAL WARMING TREND
HEADING INTO THE WEEKEND...GOING FROM 60S/40S TO 70S/50S.

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 105 AM CDT THU APR 30 2015

RIDGING ACROSS THE SOUTHERN U.S. WILL SET UP A BUFFER OVER THE PAH
FA...AS HEIGHT FALLS TO OUR NORTH AND A LONG WAVE LOW OVER THE
SOUTHWEST U.S. SHOOT PIECES OF ENERGY AROUND THE PERIPHERY OF THE
FA. SMALL PCPN CHANCES WILL EVENTUALLY MAKE THEIR WAY INTO OUR
COUNTIES...DURING THE LATTER HALF OF THE LONG TERM TIME FRAME.
CHANCES WILL BE PASSING/GLANCING...AS THE FLOW PATTERN TRANSITIONS
TO LONG WAVE TROFFING OVER THE WEST...AND RIDGING OVER THE
EAST...WITH OUR FA STUCK IN BETWEEN BUT COMING UNDER THE INFLUENCE
OF INCREASED MOISTURE/LIFT. A WARMING TREND CONTINUES...WITHS
TEMPS CLIMBING TO AROUND 80/AROUND 60.
