AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
925 PM CST TUE JAN 11 2005
.DISCUSSION...WILL KEEP DENSE FOG ADVSY GOING ALL NIGHT ACRS THE
NORTH...WITH FLOOD WATCH FOR TOMORROW NIGHT AND THURSDAY MORNING FOR
THE POTENTIAL FOR ADDITIONAL WIDESPREAD HEAVY RAINFALL OVER MOST OF
OUR FCST AREA. LATEST SURFACE MAP INDICATES WARM FRONT JUST SOUTH OF
STL TO NEAR MTO...DRIFTING SLOWLY NORTH. MODELS CONTINUE TO SHOW
FEATURE PASSING ACRS THE FCST AREA LATE TONIGHT OR FIRST THING WED
MORNING. FOG TO BE THE THICKEST TO THE NORTH OF THE BNDRY. WL KEEP
DENSE FOG ADVSY WHERE IT IS AND EXTEND IT UNTIL 600 AM WEDNESDAY
WHEN FRONT SHOULD SHIFT TO OUR NORTH TAKING THE WIDESPREAD FOG WITH
IT. RAIN CHANCES CONTINUE OVERNIGHT AS LOW LVL FLOW INCREASES INTO
SFC AND 850 MB FRONT WITH BEST THREAT FOR RAIN SHIFTING NORTH WITH
BNDRY.
&&
.PREV DISCUSSION...
MODELS INITIALIZED WELL AND ARE IN VERY GOOD AGREEMENT IN THE SHORT
TERM. ETA IS NOW FASTER WITH THE FRONT ON WED NIGHT AND MORE IN LINE
WITH THE GFS. SO BIGGEST CONCERN FOR THIS PACKAGE WILL BE AMOUNT OF
PCPN WITH THE FRONT WED NIGHT AND ALSO CHC OF SVR WX FOR TOMORROW.
TEMPS WILL ALSO BE TRICKY WITH RISING TEMPS OVERNIGHT AND SLOWLY
FALLING TEMPS ON THUR. BOTH MODELS CONSISTANT FROM PREV RUNS SO WILL
FOLLOW A BLEND FOR THIS FORECAST.
SHORT TERM...TONIGHT THROUGH FRIDAY...
SFC BOUNDARY STILL DOWN IN SOUTHERN IL WITH SCATTERED SHOWERS AND
THUNDERSTORMS MOVING EASTWARD NORTH OF THE FRONT. AS LOW LVL JET
INCREASES TONIGHT...RWS/TRWS WILL CONTINUE NORTH OF THE FRONT DURING
THE OVERNIGHT HOURS. WITH GO WITH LIKELY POPS ACRS THE AREA AND KEEP
THUNDER IN THE CNTRL AND SOUTH. DENSE FOG STILL A PROBLEM IN THE
NORTH SO WILL KEEP ADVISORY FOR OVERNIGHT...TIL ABOUT 3AM. BELIEVE
THIS WILL BE ABOUT THE TIME THE FRONT WILL LIFT BACK NORTH ACRS THE
AREA...THEN WILL JUST HAVE LIKELY RAIN ACRS THE GBG-BMI AREA. WITH
SOUTHERLY WINDS CONTINUING ACRS THE AREA OVERNIGHT...TEMPS WILL
PROBABLY BE STEADY OR SLOWLY RISING.
FUN COMES TOMORROW AS AREA GETS INTO THE WARM SECTOR AHEAD OF THE
MAIN SYSTEM. SOUTHERLY WINDS WILL CONTINUE TO ADVECT WARM MOIST AIR
INTO THE AREA. DEWPOINTS PUSH INTO THE 50S...BRINGING MORE
SPRING-TYPE WEATHER TO THE AREA FOR LATE WED INTO WED NIGHT. AS THE
MAIN 500 TROF BEGINS TO LIFT OUT OF THE SOUTHWEST...A SFC LOW WILL
MOVE OUT INTO THE PLAINS. SVR WX IS A BIG CONCERN TOMORROW AS LAPSE
RATES ARE 7-8...LIS AROUND -3 AND CAPES AROUND 500. FOR JAN THIS
APPEARS TO BE VERY UNSTABLE AIRMASS. MDL ALSO FORECASTING DECENT
FRONTOGENSIS AND OMEGA ALONG WITH THE INSTABILITY AND MOISTURE FOR
WED EVENING INTO WED NIGHT. UPPER LVL DIVERGENCE ALSO MOVES OVER THE
AREA DURING THE SAME TIME. WITH WBZ HEIGHTS JUST BELOW 8000
FT...THINK HAIL IS POSSIBLE WITH THE STRONGER STORMS. TO ADD TO THE
FUN...PW VALUES INCREASE TO 1.0-1.25 WHICH IS 300PCT ABOVE NORMAL.
NOW ADD THE FACT THAT ANY STORMS THAT DEVELOP WILL BE MOVING
NORTHEAST AND THE LOW LVL INFLOW IS FROM THE SOUTHWEST...THIS BRINGS
THE CHANCE OF TRAINING OF STORMS OVER THE AREA. SO HEAVY RAIN IS
POSSIBLE AND TRAINING STORMS COULD CAUSE SOME FLASH FLOODING OVER
PORTIONS OF THE AREA. WITH NORTHERN AREAS HAVING SOMEWHAT FROZEN
GROUND...AND CNTRL AND SOUTHERN COUNTIES ALREADY SWOLLEN AND
SATURATED...HAVE GONE WITH A FLOOD WATCH FOR THE ENTIRE AREA FOR WED
NIGHT. SO WED AND WED NIGHT WILL BE A MESSY TIME AROUND THE
AREA...WITH POSSIBLE SVR WEATHER AND FLOODING.
FRONT WILL PUSH THROUGH THE AREA WED NIGHT AND BRING NORHTWESTERLY
WINDS. EVEN THROUGH MDLS HAVE BACKED OFF ON SNOWFALL BEHIND THE
FRONT WILL CONTINUE WITH CHC OF SNOW IN FCST AS COLDER AIR ADVECTS
INTO THE AREA.
HIGH PRSS WILL THEN BUILD INTO THE AREA FOR THE REMAINDER OF THE
WEEK AND BRING MUCH BELOW TEMPS AND DRY WEATHER. DONT SEE THIS AS
RECORD TEMPS...BUT STILL WILL BE MUCH BELOW NORMAL.
LONG TERM...SATURDAY THROUGH TUESDAY...
AREA REMAINS IN BROAD CYCLONIC FLOW FOR THE WEEKEND AND NEXT WEEK.
COULD BE A CHC OF LIGHT SNOW AS A WEAK WAVE MOVES IN FROM THE
NORTHWEST ON SUNDAY. BUT FOR NOW WILL KEEP DRY AND WAIT FOR COUPLE
OF MORE MODEL RUNS. LONG RANGE MODELS NOW NOT AS DEEP WITH THE TROG
SO THEY HAVE TRENDED TO WARMER TEMPS. WONT JUMP ON THE BANDWAGON
RIGHT NOW BUT WILL TREND THAT WAY. HOWEVER...SOMETHING FUTURE
FORECASTERS WILL HAVE TO LOOK AT IF MODLS CONTINUE WITH THE SAME
TREND.
&&
.ILX WATCHES/WARNINGS/ADVISORIES...
IL...FLOOD WATCH FOR ENTIRE CWA FOR WED NIGHT.
.....DENSE FOG ADVISORY TONIGHT ROUGHLY ALONG AND NORTH
OF A RUSHVILLE TO BLOOMINGTON LINE.
