What happened

The episode as NWS PAH wrote it up.

The drought which began in May worsened considerably across southern Illinois as summer progressed. By the end of July, all of southern Illinois was upgraded to extreme to exceptional drought. The exceptional drought conditions were south of a line from Mount Carmel to Murphysboro. The remainder of southern Illinois was upgraded to extreme drought conditions. Soil moisture deficits continued to increase. By the end of July, 90 to 100 percent of the region's topsoil and subsoil moisture was reported as short or very short. Many crops were showing stress, and the situation became dire for many farmers. A majority of the corn and soybeans were listed in poor to very poor condition. Increasing amounts of livestock and pasture were showing stress. The percentage of pastures rated as poor or very poor continued to grow. Ponds across the region were dry or drying quickly. Even with the isolated rainfall from thunderstorms, fire danger remained high. Bans on outdoor burning were in place for most of southern Illinois, including Alexander, Gallatin, Hamilton, Jackson, Pope, Saline, Union, and Williamson Counties. Additionally, numerous individual towns and villages issued burn bans. Fourth of July fireworks shows were cancelled or banned in many places. Streamflows were running below normal. Residents of the Village of Thebes in Alexander County were asked to voluntarily conserve water by refraining from washing cars and watering lawns. At the Carbondale co-operative observer site, only 1.64 inches of rain fell in July, which was slightly less than one-half of the normal amount. The drought began in May and continued into August.

.SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT)
ISSUED AT 215 PM CDT SAT JUN 30 2012

TEMPERATURES ARE RUNNING CLOSE TO VALUES OBSERVED THIS TIME
YESTERDAY. HOWEVER MAY BE A DEGREE OR TWO LOWER FOR HIGHS IN SOME
AREAS. UPPER RIDGE SHIFTED TO OUR SOUTH AND EAST...THOUGH WE ARE
STILL UNDER ITS INFLUENCE. THE UPPER HIGH WILL CENTER JUST
SOUTHEAST OF THE REGION THROUGH THE SHORT TERM PERIOD. MOISTURE IS
FORECAST TO INCREASE ON THE PERIPHERY OF THE RIDGE. THIS COMBINED
WITH DIURNAL INSTABILITY AND A WEAK CAP MAY ALLOW FOR SOME
CONVECTIVE DEVELOPMENT...VERY ISOLATED...AND NOT A GIVEN. THE NAM
HAS DONE REASONABLY WELL WITH PLACEMENT AND CHANCES OF CONVECTION
WITH RECENT EVENTS. IT HINTS AT THIS POSSIBILITY TOMORROW AND
AGAIN MONDAY.

WILL LET THE EXCESSIVE HEAT WARNING CONTINUE. NO REASON TO MAKE
ALTERATIONS AT THIS POINT IN THE GAME. WILL FAVOR THE NAM MOS
GUIDANCE AS WELL. ITS BEEN WELL VERIFIED THAT GFS MOS WAS AND IS
TOO COOL AND WILL BE DISCARDED.

.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 215 PM CDT SAT JUN 30 2012

A DOMINANT MID LEVEL RIDGE OVER A LARGE PART OF THE COUNTRY...
INCLUDING THE PAH FORECAST AREA...WILL CONTINUE TO SIGNIFICANTLY
AFFECT OUR WEATHER THROUGH DAY 7. THE DROUGHT CONDITIONS AND LACK OF
RAINFALL WILL CONTINUE TO WORK IN TANDEM TO PRODUCE MORE OF THE HIGH
TEMPS WE HAVE SEEN LATELY. ON TUE HOWEVER...THERE IS A GLIMMER OF
HOPE FOR MAINLY PARTS OF SRN IL/SWRN IND/KY PENNYRILE REGION AS A
WEAKNESS IN THE RIDGE DEVELOPS ACROSS THE LOWER MS/OH VALLEYS. THIS
FEATURE COULD COMBINE WITH INCREASED PWATS AND INDUCE ENOUGH
INSTABILITY FOR WIDELY SCT TSTM ACTIVITY. THIS LIMITED CHANCE OF
MEASURABLE PCPN MAY LINGER INTO WED MAINLY IN SWRN IND/PENNYRILE
REGION. WE DECIDED TO GO ALONG WITH PCPN PATTERNS SUGGESTED BY THE
CENTRAL REGION MODEL BLEND...BUT DOWNPLAYED THE POP A BIT...BASED ON
THIS CURRENT DRY REGIME. BEYOND WED...THERE WERE SOME WEAK PCPN
SIGNALS IN THE BLEND...BUT THE MED RANGE MODELS SHOW THAT THE JET
STREAM AND THE RIDGE WILL MIGRATE NWD...THUS WE KEPT THE FORECAST
DRY.

ADDED IN SOME WMODEL TRENDS FOR THE TEMPS...WHICH MADE THE DIURNAL
SWING OF TEMPS A FEW DEGREES GREATER...REFLECTING RECENT OBS.
AFTERNOON DEW POINTS WERE ENHANCED BY RAW MODEL DATA TO ATTEMPT TO
FORECAST A MIXDOWN OF DRIER AIR FROM ABOVE. IT DOES APPEAR THAT BY
DAY 7 /SAT/...DEW POINTS MAY APPROACH 70...BUT UNTIL THEN...DEW
POINTS SHOULD BE SUCH THAT THE HEAT INDICES WILL BE VERY CLOSE TO
THE TEMPS.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1145 PM CDT SAT JUN 30 2012

NO SIGNIFICANT WEATHER TONIGHT WITH LIGHT AND VARIABLE WINDS AND
MAYBE SOME MID/HIGH CLOUDS FROM CONVECTION UPSTREAM. SOME MVFR
FOG IS POSSIBLY BRIEFLY AT KCGI TOWARD 11Z OR 12Z. MOISTURE STARTS
TO INCREASE IN THE 800MB-700MB LAYER ON SUNDAY...WHICH COULD
PROMPT THE DEVELOPMENT OF SOME VERY HIGH BASED CUMULUS AND EVEN
SOME ISOLATED SHOWERS OR THUNDERSTORMS...BUT COVERAGE AND EXACT
LOCATION OF DEVELOPMENT IS STILL SUSPECT RIGHT NOW SO WILL LEAVE
IT OUT OF THE FORECAST. HIGH DENSITY ALTITUDES WILL CONTINUE AS
WELL DURING THE DAY AS WE REMAIN IN THIS HOT HIGH PRESSURE REGIME.
