AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1109 PM CDT MON OCT 25 2010

.DISCUSSION...
ISSUED 815 PM CDT MON OCT 25 2010

LOW PRESSURE CONTINUES TO DEEPEN OUT ALONG THE MISSOURI RIVER THIS
EVENING AND ONCE THE LOW SHIFTS NE INTO NRN IOWA IN THE NEXT SEVERAL
HOURS...LOOK FOR THE COLD FRONT TO BEING RACING EWD. STRONG 500 MB
HEIGHT FALLS OVER WESTERN NEBRASKA (150 METERS!) SHOULD SHIFT EWD
WITH TIME THIS EVENING WITH THE UPPER WAVE FORECAST TO BECOME
NEGATIVELY TILTED BY 09Z. SCATTERED SHOWERS AND THUNDERSTORMS WILL
BE POSSIBLE THIS EVENING WITH THE STRONG MOISTURE AND THERMAL
ADVECTION PATTERN AHEAD OF THE DEEP LOW...BUT THE MAIN SQUALL LINE
WITH DAMAGING STRAIGHT LINE WINDS STILL LOOKS TO BE PUSHING IN
TO OUR WESTERN AREA BETWEEN 2 AND 3 AM AND SHOULD BE EAST OF OUR
AREA BY 10 OR 11 AM TUESDAY. WIND SHEAR PROFILES SUGGEST THE
POTENTIAL FOR ISOLD BRIEF TORNADOES AS WELL ALONG THE FAST MOVING
CONVECTIVE LINE. ONCE THE STORMS CLEAR OUR AREA LATE TUESDAY
MORNING...STRONG GRADIENT WINDS ARE EXPECTED AS THE DEEP UPPER AND
SFC LOWS TRACK INTO MINNESOTA.

CURRENT ZONES HAVE THE EVENING TRENDS WELL IN HAND SO OTHER THAN
THE USUAL UPDATES TO THE EARLY EVENING TEMP GRIDS...NO ZONE FORECAST
UPDATE WILL BE NEEDED AT THIS TIME.

.AVIATION...
ISSUED 1105 PM CDT MON OCT 25 2010

LITTLE CHANGE FROM PREVIOUS DISCUSSION...TIMING OF SQUALL LINE
INTO OUR TAF SITES AND STRONG GRADIENT WINDS THE MAIN FORECAST
CONCERNS THIS PERIOD. COLD FRONT WAS STARTING TO PUSH ACRS
WRN IA LATE THIS EVENING WITH SCATTERED SHOWERS AND THUNDERSTORMS
DEVELOPING WELL AHEAD OF THE FRONT. THE MAIN THREAT WILL BE WITH
THE LINE OF STORMS WHICH IS STILL EXPECTED TO PUSH IN AFTER 07Z
ACRS OUR WEST AND APPRCHG OUR EASTERN AREAS BY DAWN TUESDAY.
POCKETS OF MVFR CIGS HAVE MOVED INTO THE AREA DURING THIS EVENING
AND EXPECT THAT TO BE THE STORY OVERNIGHT. LOOK FOR THE POTENTIAL
FOR SFC WIND GUSTS APPRCHG 60 MPH WITH THE SQUALL LINE. WINDS JUST
OFF THE SFC WERE 50-60 KTS ALREADY THIS EVENING AND ANY ORGANIZED
CELL WILL HAVE THE POTENTIAL TO BRING DOWN GUSTY WINDS. SFC WIND
GUSTS HAVE HELD UP THIS EVENING AND WITH THE CONVECTION INCRG TO
OUR WEST WILL TAKE OUT THE LLWS. EXPECT SFC WIND GUSTS TO BE UP
TO 40 MPH IN A FEW AREAS...OUTSIDE OF ANY CONVECTION.

THE SQUALL LINE AND COLD FRONT WILL RACE TO THE EAST OF THE TAF
SITES BY NO LATER THAN 15Z TUESDAY...WITH STRONG GRADIENT WINDS
PREVAILING THRU THE REMAINDER OF THE PERIOD. ANY MVFR CIGS SHOULD
LIFT OFF TO OUR NORTH AND EAST BY LATE MRNG OR EARLY AFTN. SFC WINDS
TNT WL CONTINUE FROM A SSE (150-180 DEGREES) DIRECTION...AND THEN
VEER MORE INTO A SSW (210-240) DIRECTION TUE MRNG WITH A FEW GUSTS
APPRCHG 45 KTS...ESP ACRS THE NORTH.

.PREV DISCUSSION...
ISSUED 300 PM CDT MON OCT 25 2010

SHORT TERM...TONIGHT THROUGH THURSDAY...
ALL OF THE SIGNIFICANT WEATHER FOR THE SHORT TERM WILL BE PACKED
INTO TONIGHT AND THE FIRST PART OF TUE. A POWERFUL UPPER JET
CONTINUES TO FLOW FROM THE WEST COAST INTO THE ROCKIES. THIS IS
ALREADY CAUSING CYCLOGENESIS OVER THE WRN PLAINS WITH WELL DEVELOPED
LOWS CENTERED OVER SD AND KS. THE KS LOW WILL SWING NE AND MEET UP
WITH THE DAKOTAS LOW...PRODUCING RAPID DEEPENING OVER MN. THE
TRAILING COLD FRONT WILL MOVE EWD AND BE ACCOMPANIED BY A THIN
FORCED LINE OF CONVECTION WHICH WILL LIKELY ENTER THE WRN FORECAST
AREA SHORTLY AFTER 06Z. CONVECTIVE INSTABILITY WILL BE KIND OF
WEAK...BUT THE STRONG FORCING AND AGEOSTROPHIC CIRCULATIONS ALONG
WITH PRECIPITATION LOADING SHOULD FOSTER EFFICIENT DOWNWARD MOMENTUM
TRANSFER. THUS...DAMAGING WINDS WILL BE THE THE PRIMARY SEVERE
WEATHER THREAT UNTIL THE FRONT CLEARS THE IL/IN BORDER BY 15Z TUE.
VEERING WINDS IN THE LOWER KILOMETER OR TWO MAY ALSO SUPPORT SMALL
SUPERCELLS OR LEWPS EMBEDDED IN LINE SEGMENTS.

EVEN AFTER THE FRONT PASSES THROUGH...A STRONG PRESSURE GRADIENT
WILL BE MAINTAINED WITH WLY TO SWLY WINDS AT OR ABOVE ADVISORY
CRITERIA THROUGH AT LEAST THE DAYLIGHT HOURS TUE. WILL KEEP THE WIND
ADVISORY GOING AS IS...BUT EXTEND IT SWD TO ENCOMPASS THE REMAINDER
OF THE FORECAST AREA. THE ADVISORY MAY NEED TO BE EXTENDED INTO TUE
NIGHT AND/OR WED...BUT THIS CAN BE ADDRESSED IN LATER FORECAST
ISSUANCES. THE REMAINDER OF THE SHORT TERM WILL DRY BUT TURNING
COOLER TOWARD THU.

LONG TERM...FRIDAY THROUGH MONDAY...
THE LONG TERM LOOKS FAIRLY TRANQUIL AS THE DEEP LOW NORTH OF THE
GREAT LAKES CONTINUES NWD THROUGH CANADA AND THE SURFACE PRESSURE
GRADIENT RELAXES. SURFACE HIGH INITIALLY OVER THE MID MS VALLEY FRI
WILL MOVE OFF THE EAST COAST BY EARLY NEXT WEEK. THE OVERALL UPPER
PATTERN WILL TRANSITION TO A LESS AMPLIFIED AND OVERALL FASTER ZONAL
FLOW. A DEEP UPPER LOW THAT COMES INTO THE WEST COAST FRI WILL
LIKELY WEAKEN AS IT GAINS SPEED AND MOVES INTO THE PLAINS AROUND SUN
OR MON. THE ECMWF AND GFS HAVE YET TO COME TO A CONSENSUS REGARDING
THE EVOLUTION OF THIS FEATURE...SO WILL LEAVE POPS BELOW MENTIONABLE
VALUES FOR NOW FOR SUN AND MON. AFTER A COOL START ON FRI WITH LOWS
IN THE LOW TO MID 30S AND HIGHS IN THE 50S... TEMPERATURES WILL
MODERATE TO MORE SEASONABLE LEVELS FOR THE WEEKEND.
