AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
158 PM CDT THU APR 5 2007

.DISCUSSION...
MAIN SHORT-TERM CONCERN WILL BE THE CHILLY TEMPS OVER THE NEXT
FEW DAYS...AS NORTHWESTERLY FLOW PATTERN CONTINUES ACROSS THE
MIDWEST. IN THE LONGER-TERM...EMPHASIS WILL BE ON TIMING OF
APPROACHING STORM SYSTEM FOR THE MIDDLE OF NEXT WEEK.

18Z SURFACE CHART SHOWS RIDGE OF HIGH PRESSURE STRETCHING ACROSS
THE CENTRAL PLAINS...MAINTAINING A COOL NORTHWESTERLY FLOW ACROSS
MUCH OF THE EASTERN CONUS. ALOFT...LARGE LOW CONTINUES TO SPIN
OVER THE EASTERN GREAT LAKES...WHILE RIDGING BUILDS WEST OF THE
ROCKIES. NEXT SHORT-WAVE OF INTEREST TO CENTRAL ILLINOIS IS
EVIDENT ON WATER VAPOR IMAGERY...DROPPING SOUTHEASTWARD THROUGH
ALBERTA AND SASKATCHEWAN.

&&

SHORT TERM...TONIGHT THROUGH SUNDAY...
LINGERING CLOUD COVER ASSOCIATED WITH GREAT LAKES LOW WILL DEPART
THE AREA EARLY THIS EVENING...LEAVING BEHIND MOSTLY CLEAR SKIES.
MEANWHILE...AN UPPER DISTURBANCE TRACKING FROM THE CENTRAL ROCKIES
TOWARD THE SOUTHERN PLAINS MAY SPREAD A FEW MID/HIGH CLOUDS ACROSS
PARTS OF THE REGION OVERNIGHT. BASED ON LATEST SATELLITE
LOOPS...AS WELL AS NAM-WRF RH PROFILES...THINK BULK OF CLOUD COVER
WILL REMAIN JUST W/SW OF THE KILX CWA TONIGHT. WILL THEREFORE GO
WITH MOSTLY CLEAR SKIES. GIVEN THE CLEAR SKIES AND DIMINISHING
WINDS...GOOD RADIATIONAL COOLING CONDITIONS WILL SET UP...ALLOWING
TEMPS TO DROP SEVERAL DEGREES LOWER THAN THEY DID LAST NIGHT.
CURRENT SURFACE DEWPOINTS ARE ONLY IN THE TEENS AND LOWER
20S...HOWEVER WITH WINDS REMAINING AROUND 10 MPH OVERNIGHT...DO
NOT THINK TEMPS WILL DIP QUITE THAT COLD. WILL GO WITH LOWER TO
MIDDLE 20S ACROSS THE BOARD...JUSTIFYING THE CONTINUANCE OF A
FREEZE WARNING ACROSS THE ENTIRE CWA.

SHORT-WAVE ACROSS CANADA DROPS SOUTHEASTWARD ON FRIDAY...BRINGING
AN INCREASE IN CLOUD COVER. LATEST FORECAST SOUNDINGS DO NOT
INDICATE QUITE AS MUCH CLOUD COVER AS PREVIOUSLY FORECAST...SO
WILL CUT BACK ON THE SKY COVER A BIT...AND GO WITH A PARTLY SUNNY
FORECAST. WAVE TRACKS ACROSS THE AREA LATE FRIDAY...BRINGING A
RE-ENFORCING SHOT OF COLDER AIR. 1000-500MB THICKNESSES ARE
PROGGED TO DROP BELOW 5200 FRIDAY NIGHT AND SATURDAY...INDICATING COLDER
TEMPS. IN ADDITION...STRONG LOW-LEVEL CAA PATTERN AND DEEP
CYCLONIC FLOW ALOFT...SUGGEST A CHANCE FOR SNOW FLURRIES THROUGH
THE PERIOD. BASED ON DEEPEST LOW-LEVEL MOISTURE PROFILES...WILL
KEEP THE FLURRIES GENERALLY ALONG AND NORTH OF I-72 FRIDAY NIGHT
AND SATURDAY. WILL ALSO ADJUST TEMPS DOWN A BIT...FOLLOWING THE
COLDER MET GUIDANCE NUMBERS MOST CLOSELY. COLDEST NIGHT OF THIS
ARCTIC OUTBREAK WILL BE FRIDAY NIGHT...WHEN TEMPS DIP TO AROUND 20
DEGREES...WITH TEENS IN FAVORED LOW-LYING AND RURAL LOCATIONS.
WOULD BE EVEN COLDER...BUT CLOUDS AND WIND SHOULD KEEP TEMPS FROM
FALLING FURTHER. COLD WEATHER EXPECTED TO LINGER INTO SUNDAY...HOWEVER
TEMPS SHOULD BEGIN TO MODERATE SOMEWHAT AS UPPER FLOW BECOMES LESS
CYCLONIC AND HEIGHTS START TO RISE.

LONG TERM...MONDAY THROUGH THURSDAY...
IN THE EXTENDED...UPPER FLOW BECOMES MORE ZONAL...ALLOWING A
DEVELOPING STORM SYSTEM TO APPROACH THE REGION BY THE MIDDLE OF
NEXT WEEK. MEDIUM RANGE MODELS HAVING DIFFICULTY WITH REGARDS TO
TRACK AND TIMING OF SYSTEM...WITH GFS APPEARING TO BE THE LEAST
CONSISTENT OF THE MODELS. 00Z RUN OF THE GFS FEATURED A SOUTHERLY
TRACK OF THE UPPER/SURFACE FEATURE...INDICATING A POSSIBLE
OVERRUNNING RAIN EVENT ACROSS CENTRAL ILLINOIS ON WEDNESDAY. 12Z
RUN IS DRASTICALLY DIFFERENT...SPEEDING SYSTEM UP BY ABOUT 24
HOURS AND SHIFTING IT WELL NORTHWARD ACROSS NORTHERN ILLINOIS.
MEANWHILE...BOTH CANADIAN AND ECMWF HAVE BEEN MUCH MORE CONSISTENT
RUN-TO RUN WITH A FURTHER NORTH SOLUTION. HAVE THEREFORE OPTED TO
THROW OUT THE 12Z GFS...IN FAVOR OF THE CANADIAN/GFS CONSENSUS.
STICKING WITH THE SLOWER AND FURTHER NORTH TRACK...WILL KEEP
TUESDAY DRY...WITH ONLY SILENT 20 POPS. FAVORED TIME FOR RAIN
SHOWERS WILL BE TUESDAY NIGHT INTO WEDNESDAY. AFTER THAT...COOLER
AIR SETTLES BACK INTO THE REGION FOR THE END OF NEXT WEEK...AS UPPER
FLOW AGAIN BECOMES NORTHWESTERLY.
