What happened

The episode as NWS PAH wrote it up.

One of the warmest and driest Mays on record worsened the rare spring drought over southern Illinois. By the end of May, the drought was severe in the counties along the Ohio River. Moderate drought conditions existed elsewhere to the southeast of a line from Fairfield to Carbondale. At Carbondale, spring of 2012 was the second driest spring on record. Only 6.50 inches of rain fell from March through May. The month of May was the driest on record. Only 0.40 inch fell at Carbondale in May. Soils continued to dry out, and topsoil moisture deficits began to be reported. Streamflows were running below normal by the end of the month.

.SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT)
ISSUED AT 232 PM CDT FRI MAY 11 2012

OVER THE NEXT 18-24 HOURS CLOUDINESS WILL CONTINUE TO LOWER AND
INCREASE AS A STORM SYSTEM MOVES SLOWLY NORTHEAST OUT OF THE
SOUTHERN PLAINS.

A WEDGE OF DRY AIR IN THE LOWER LEVELS WILL BE DIFFICULT TO
OVERCOME...BUT MODELS ARE NOW IN DECENT AGREEMENT IN SHOWING
SATURATION IN THE LOWER LEVELS ALLOWING OVERRUNNING PRECIP ON THE
NORTH SIDE OF THIS SYSTEM TO SPREAD NORTHWARD INTO OUR CWA
STARTING LATE SATURDAY MORNING. BY 00Z SUNDAY (7 PM SATURDAY)
PRECIP CHANCES WILL HAVE MADE THEIR WAY ACROSS THE ENTIRE
CWA...WITH THE BEST CHANCES OVER THE SOUTHERN SECTIONS.

THE SURFACE LOW ASSOCIATED WITH THIS SYSTEM IS FORECAST TO SLOWLY TRACK
FROM NORTHEAST LOUISIANA AT 7 PM THIS EVENING...TO SOUTH CENTRAL
TENNESSEE BY 7 PM SUNDAY...TO FAR EASTERN KENTUCKY AT 7 AM MONDAY.
DYNAMICALLY SPEAKING...THIS TRACK WILL GENERATE THE BEST PRECIP
CHANCES GENERALLY ALONG AND SOUTHEAST OF THE OHIO RIVER...ESPECIALLY
LATE SATURDAY NIGHT INTO SUNDAY.

FORECAST STORM TOTAL QPF WILL RANGE FROM AROUND AN INCH OVER THE
SOUTHEAST SECTIONS OF OUR CWA TAPERING OFF AROUND A QUARTER INCH
OVER THE NORTHWEST SECTIONS. A SLIGHT DEVIATION IN STORM TRACK AND
TIMING COULD MAKE A SIGNIFICANT DIFFERENCE IN QPF AMOUNTS.
INSTABILITY VALUES THROUGHOUT THE EVENT NOT TOO IMPRESSIVE SO
TRIED TO TONE DOWN THUNDER CHANCES AS MUCH AS POSSIBLE.

AS THE STORM SYSTEM MOVES NORTHEAST OF THE REGION SUNDAY NIGHT...PRECIP
CHANCES WILL BEGIN TO DIMINISH FROM WEST TO EAST.

.LONG TERM...(MONDAY THROUGH FRIDAY)
ISSUED AT 232 PM CDT FRI MAY 11 2012

ON MONDAY...MODELS SHOW THE SURFACE COLD FRONT WILL BE WELL THROUGH
THE REGION...BUT THE ECMWF KEEPS SOME VERY LIGHT QPF ACROSS THE
SOUTHEAST HALF OF THE PAH FORECAST AREA...WHILE GFS PUSHES ALL
PRECIP EAST OF THE FA BY 12Z MONDAY.  KEPT SOME POPS FOR THE EASTERN
THIRD OF OUR COUNTIES...BUT TRIMMED DOWN THE COVERAGE AND ALSO WENT
FROM CHANCE TO JUST SLIGHT CHANCE POPS.  TEMPERATURES WILL BE A
LITTLE BELOW NORMAL WITH DECENT NORTHERLY WINDS BEHIND THE FRONT.
THE UPPER TROF WILL MAKE WAY ACROSS THE AREA MONDAY NIGHT...WITH NO
MOISTURE TO WORK WITH...SKIES SHOULD CONTINUE TO CLEAR FROM WEST TO
EAST.

SURFACE HIGH PRESSURE BUILDING OVER THE CENTRAL PLAINS WILL KEEP OUR
REGION DRY WITH NORTHERLY WINDS THROUGH WEDNESDAY NIGHT.  OVERNIGHT
LOW WILL BE NEAR SEASONAL...BUT GRADUALLY WARMING DAYTIME HIGHS CAN
BE EXPECTED WITH PLENTIFUL SUNSHINE.  BOTH GFS AND ECMWF SHOW A WEAK
SURFACE LOW NEAR THE REGION LATE WEDNESDAY INTO WEDNESDAY NIGHT.
GFS PRODUCES A BIT OF QPF...WHILE ECMWF KEEPS US DRY.  AGAIN...WITH
LITTLE MOISTURE TO WORK WITH...STAYED WITH A DRY FORECAST BUT
INCREASE CLOUD COVER A LITTLE BIT.

ON THURSDAY...THE SURFACE HIGH WILL MOVE EAST OF THE FA.  WINDS WILL
BECOME LIGHT SOUTHERLY.  THIS WILL CONTINUE OUR WARM UP THROUGH
FRIDAY...WITH HIGHS THURSDAY AND FRIDAY IN THE LOWER TO MIDDLE
80S.
