Area forecast discussion, Nov 9, 8:40 PM CST, 9 hours 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 840 PM CST MON NOV 9 1998 FCST PROBLEM FOR TONIGHT AND TUESDAY IS STRONG/DAMAGING GRADIENT WINDS EXPECTED WITH INTENSE LOW PRESSURE IN THE PLAINS. THIS LOW IS PROGD TO DEEPEN SIGNIFICANTLY AFTER MIDNIGHT WITH PRESS FALLS OF GRTR THAN 1 MB PER HOUR AS IT TRACKS TO WRN LK SUPERIOR BY TUE AFTN. THIS VERY TIGHT GRADIENT WILL RESULT IN RAPIDLY INCRSG WINDS ACRS CENT IL LATE TONIGHT AND DURING THE DAY TUESDAY. TWO MAJOR CONCERNS WITH THE AFOREMENTIONED SCENARIO. FIRST... SHOWERS AND THUNDERSTORMS XPCTD TO DEVELOP AHEAD OF THE ADVANCING CDFNT WILL BE MOVG RAPIDLY WITH 850MB WINDS PROGD TO BE GRTR THAN 70 KNOTS. I FEEL THAT A MODERATE SHOWER...AND ESPECIALLY A THUNDERSTORM...WILL BE CAPABLE OF TRANSFERING PLENTY OF MOMENTUM TO THE SURFACE TO RESULT IN DAMAGING WINDS TOWARD THE EARLY MORN HOURS. SECOND AND BIGGEST CONCERN IS THE GRADIENT WINDS FORECAST FOR TUESDAY. WITH THE MAGNITUDE OF THE INTENSE LOW PRESSURE SYSTEM I BELIEVE THAT HIGH WIND WARNING CRITERIA (SUSTAINED WIND 40 MPH OR GRTR...OR GUSTS 58 MPH OR HIGHER) AND DAMAGING WINDS CAN BE EXPECTED FOR SEVERAL HOURS ON TUESDAY IN CENT IL FROM MID-MORNING INTO EARLY AFTERNOON. FWC WIND FORECASTS SUPPORT THIS NOTIION...INDICATING SUSTAINED WINDS OF 38-48 MPH ACRS ALL OF CENT/ERN IL LATE MORN-ERLY AFTN TUESDAY. CURRENT PROFILER DATA IN THE LOWEST GATES JUST DOWNSTREAM OF A 992MB SFC LOW IN THE SRN PLAINS ALREADY SHOW 40 KT WINDS...WITH FURTHER STRENGTHENING XPCTD AS THE LOW DEEPENS. AS A RESULT...WOULD LIKE TO GET THE WORD OUT ASAP INSTEAD OF WAITING FOR 4AM ZONES. BELIEVE A WIND EVENT OF THIS MAGNITUDE SHOULD HAVE PLENTY OF ADVANCE NOTICE. THUS...WILL BE UPGRADING WIND ADVISORY TO A HIGH WIND WARNING FOR LATE TONIGHT AND ESPECIALLY ON TUESDAY. COORD WITH CHI...STL AND DVN. MILLER
