What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 26, 3:04 PM CDT, 1 hour 10 minutes earlier.

Area forecast discussion, Jul 26, 3:04 PM CDT, 1 hour 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
305 PM CDT TUE JULY 26 2005

.DISCUSSION...
MUCH NEEDED RAINFALL IS ON THE HORIZON. THE QUESTIONS FOR TONIGHT
IS HOW LONG WILL IT LAST AND HOW MUCH WILL WE GET. COOLER AIR WILL
ACCOMPANY THE RAIN AS A COLD FRONT SWEEPS THROUGH THE STATE TONIGHT
AND EARLY WEDNESDAY. SEASONABLE TEMPERATURES WILL BE THE RULE FOR
THE REST OF THE WEEK AND INTO THE WEEKEND...BUT THERE WILL ALSO BE
ALOT OF DRY AIR AND LITTLE CHANCE FOR RAIN.

SHORT TERM...TONIGHT THROUGH FRIDAY...
THE LATEST SURFACE ANALYSIS INDICATED A FRONT FROM CHI-GBG TO A
LOW NEAR UIN. THIS WAVE WILL MOVE ALONG THE FRONT EARLY THIS EVENING
ENHANCING RAINFALL WEST OF THE IL RIVER. MOST OF RAIN IS
POST-FRONTAL WITH LIGHT SHOWERS AND EMBEDDED T-STORMS. A PRE-FRONTAL
TROF NEAR I-57 AND BETTER INSTABILITY WILL ALSO FOCUS SCATTERED
T-STORMS THIS EVENING...WITH MORE WIDESPREAD RAIN ANTICIPATED LATER
IN THE EVENING AND OVERNIGHT. WITH THE HOT AND HUMID AIR IN PLACE
OVER SOUTHEAST IL AND PARTLY CLOUDY CONDITIONS ANTICIPATED EARLY IN
THE EVENING...WILL KEEP THE HEAT ADVISORY GOING SOUTH OF I-70 UNTIL
7 PM.

THE COLD FRONT IS EXPECTED TO MOVE THROUGH SE IL BY WED MORNING.
SCATTERED POST-FRONTAL SHOWERS ARE EXPECTED TO CONTINUE SOUTHEAST OF
A SHELBYVILLE-DANVILLE LINE DURING THE MORNING...AND SOUTH OF I-70
INTO EARLY AFTERNOON. THE REST OF THE FORECAST AREA WILL ENJOY MUCH
COOLER CONDITIONS WITH TEMPERATURES IN THE UPPER 70S WEDNESDAY
AFTERNOON. HIGH PRESSURE RIDGING ACROSS THE STATE ON THURSDAY WILL
RESULT IN DRY CONDITIONS AND TEMPS IN THE LOWER 80S.

AN UPPER TROF IS EXPECTED TO SWING DOWN INTO THE UPPER MIDWEST LATER
ON THURSDAY...BRINGING A WEAK COLD FRONT TOWARD NORTHERN IL BY
EVENING. AS THIS FRONT SLOWLY APPROACHES NW AND NCENT IL FRIDAY...
THERE COULD BE A FEW SHOWERS WITH THIS. WILL LEAVE OUT A MENTION IN
THE ZONE FORECAST FOR NOW...BUT WILL PUT A 20 POP IN THE GRIDS NORTH
OF A CANTON-PIA-EL PASO LINE. OTHERWISE...TEMPS TYPICAL FOR LATE
JULY AND A FEW CLOUDS ARE ANTICIPATED.

LONG TERM...SATURDAY THROUGH TUESDAY...
HIGH PRESSURE AND AN EASTERLY FLOW WILL KEEP THE WEATHER DRY AND
TEMPS AT OR JUST ABOVE SEASONAL NORMALS THROUGH THE WEEKEND AND INTO
EARLY NEXT WEEK. THE EXCEPTION MAY BE SOUTH OF I-70 WHERE PART OF A
WEAK UPPER TROF NEARLY STATIONARY IN THE TN VALLEY MAY RESULT IN
MORE CLOUDS AND SCTD SHOWERS IN SOUTHERN IL MON AND TUE AFTERNOONS.
AT THIS TIME IT LOOKS LIKE THEY MAY STAY FAR ENOUGH TO SOUTH OF THE
FORECAST AREA...SO WILL LEAVE OUT OF THE FORECAST AND GRIDS FOR NOW.

.ILX WATCHES/WARNINGS/ADVISORIES...
