Area forecast discussion, Nov 17, 5:41 AM CST, 2 hours 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
541 AM CST TUE NOV 17 2009

.DISCUSSION...
ISSUED 249 AM CST TUE NOV 17 2009

LATEST SFC ANALYSIS INDICATED 1010 MB LOW PRESSURE JUST NORTH OF
KPAH...HAVING MOVED VERY LITTLE SINCE 00Z. TIGHT GRADIENT BETWEEN
LOW AND 1030 MB HIGH DRAPED ACROSS THE NRN GRT LAKES CONTINUED TO
PRODUCE 15-25 MPH NE WINDS. ALOFT...W/V IMAGERY SHOWED UPPER LOW
SLOWLY SWIRLING EAST NEAR KSGF. 00Z U/A ANALYSIS SHOWED A STRONG
70-90 KT JET STREAK ROUNDING THE BASE OF THE MID LEVEL TROUGH IN
ARK. IMPRESSIVE UPPER DYNAMICS AND PVA ON THE N/E SIDE OF THE
UPPER LOW COUPLED WITH FAVORABLE LEFT EXIT REGION OF 250 MB JET
MAX...WAS SETTING UP A SOLID DEFORMATION ZONE BAND OF
RAIN...ARCING FROM WRN KENTUCKY...NW THROUGH CENTRAL IL...AND BACK
INTO IA AND MO. RECENT COOLING CLOUD TOPS ON IR SAT IMAGERY IN SE
ILLINOIS INDICATING NEXT ROUND OF HEAVIER RAINS DEVELOPING AND
SWEEPING NW. FORECAST CHALLENGE CONTINUES TO BE RAIN TRENDS AND
AMOUNTS AS THE SYSTEM SLOWLY LIFTS UP THE MISSISSIPPI VALLEY
THROUGH WED.

SHORT TERM...TODAY THROUGH THURSDAY
EXPECT STEADIER DEFORMATION ZONE RAINS TO LIFT NORTH ACROSS THE CWA
THIS MORNING...AND CONTINUE TO AFFECT AREAS NORTH OF I-70 WELL
INTO THE AFTERNOON. X-SECTIONS AND FCST SOUNDINGS SUGGEST THE DRY
SLOT WILL PUNCH NORTH THROUGH AT LEAST THE SOUTHERN THIRD OF THE
STATE BY MID AFTERNOON...LEAVING JUST SOME LIGHT SHOWERS OR
DRIZZLE IN SHALLOWER MOISTURE PROFILES IN THE SE BEYOND MIDDAY. BY
EVENING MOST OF THE MDT RAINFALL SHOULD EASE AS THE WARM
CONVEYOR/MOISTURE SOURCE BECOMES FARTHER DETACHED FROM THE UPPER
SYSTEM. THROUGH THE DAYLIGHT HOURS ANOTHER HALF TO 3/4 INCH IS
POSSIBLE WITH THE HEAVIER TOTALS FOCUSED ON THE CENTRAL AND
NORTHERN CWA. WILL CONTINUE FLOOD WATCH UNTIL 00Z WED SW OF A
CANTON TO LINCOLN LINE...MAINLY FOR RISES ON AREA CREEKS AND
STREAMS. STIFF NE WINDS WILL CONTINUE TO BLOW...AND ALONG WITH
THICK CLOUD COVER AND PRECIP...HIGHS SHOULD BE IN THE SAME
TERRITORY AS THE PAST COUPLE DAYS...MID 40S NORTH HALF TO LOWER
50S SOUTH OF I-70.

UPPER LOW WILL SLOWLY LIFT NORTH THROUGH WRN IL TUE NIGHT/WED
CONTINUING SCATTERED SHOWERS...HOWEVER COVERAGE AND QPF WILL BE
MUCH LIGHTER THAN THE MON/TUE TIMEFRAME SAW. HEART OF LOW/MID
LEVEL COLD POOL MOVES OVERHEAD WED...SO ANOTHER DAY OF CHILLY
TEMPS EXPECTED. 850 MB TEMPS FALL BELOW 0 C BY WED EVENING...BUT
LLVL THERMAL PROFILES STILL TO WARM TO ALLOW ANY FLAKES TO REACH
THE SFC...EVEN IN THE NW. WITH RIDGING HOLDING STRONG EAST OF THE
GRT LAKES...UPPER SYSTEM WILL BE SLOW TO DEPART NRN IL...AND WILL
HAVE TO EXTEND MENTIONABLE POPS INTO THU ACROSS THE NORTH.

LONG TERM...FRIDAY THROUGH MONDAY
MEDIUM RANGE MODELS CONTINUE TO STRUGGLE WITH THE EVOLUTION OF THE
SFC AND UPPER FEATURES DURING THE EXTENDED PERIODS. 00Z ECMWF
SWINGS A WEAK NRN STREAM WAVE ACROSS THE UPPER MIDWEST LATE FRI
AND SAT...HOWEVER MOISTURE REMAINS TIED UP ALONG THE GULF COAST
WITH A SEPARATE SRN STREAM WAVE. LATEST GFS RUN REALLY DAMPENS THE
NRN STREAM SYSTEM AS IT DIVES INTO THE MIDWEST...WHILE THE SRN
WAVE SKIRTS ALONG THE GULF COAST AND SE U.S. THROUGH THE WEEKEND.
THIS WOULD LEAVE THE MIDWEST HIGH AND DRY WHILE THE NEXT UPPER
TROUGH DIGS EAST OF THE ROCKIES INTO EARLY NEXT WEEK. WITH LOW
CONFIDENCE ON THE OVERALL PATTERN DEVELOPMENT...WILL NOT MAKE ANY
CHANGES TO THE EXTENDED POP GRIDS...AND THERE IS A CHANCE WE COULD
REMAIN DRY THROUGH THE PERIOD. TEMPERATURES ARE EXPECTED TO RUN A
FEW DEGREES ABOVE NORMAL.

&&

.AVIATION...
ISSUED 532 AM CST TUE NOV 17 2009
NOT A LOT OF CHANGE. PREDOMINANTLY MVFR AND IFR CIGS FOR TAF
SITES. SOME DRY AIR MOVING INTO SYSTEM ALLOWING FOR VFR
BREAKS...BUT JUST FOR SHORT PERIODS OF TIME AS RAIN AND 4SM TO 5SM
VSBYS ARE THE RULE. AS LOW MOVES OVER CWA LATER IN THE FCST
PD...THE VSBYS EXPECTED TO DROP AS PRECIP REDUCES TO DRIZZLE FOR
THE OVERNIGHT HOURS WITH SOME SHOWERS. SOME GUIDANCE TAKING VSBY
DOWN TO LIFR FOR SPI AND DEC...BUT WILL START THE TREND DOWN AND LEAVE
THAT FOR TEMPO GROUPS IN SUBSEQUENT FCSTS.
