Area forecast discussion, Sep 19, 3:15 AM CDT, 11 hours 22 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 315 AM CDT MON SEP 19 2005 .SYNOPSIS...WEAK LOBE OF HIGH PRESSURE EXTENDS FROM CENTRAL PLAINS INTO IOWA BEHIND COLD FRONT WITH LOWER DEWPOINTS AND SLIGHTLY COOLER AIR. SATELLITE AND SURFACE/UPPER AIR ANALYSIS ALL SHOW QUIET CLEAR SKIES WITH SFC HIGH MOVING NORTHEAST TODAY INTO GREAT LAKES TONIGHT. && .SHORT TERM...(TODAY AND TONIGHT)...LIMITED MIXING TODAY AND TRAJECTORIES TODAY FROM EASTERN NEBRASKA SUPPORT HIGHS MAINLY LOWER 80S WITH A FEW UPPER 70S FAR NE...OR LOW END OF GUIDANCE TODAY DESPITE CLEAR SKIES BUT WEAKENING LATE SEPTEMBER SUN ALSO HARDER TO SEE MAJOR WARMUP TODAY. LIGHT WINDS TODAY AS HIGH PASSED ACROSS AREA. TONIGHT...AGAIN CLEAR WITH LIGHT SOUTH TO SOUTHEAST WINDS FOR MODERATE RADIATIONAL COOLING. SOME INCREASE IN DEWPOINTS BUT BASED ON AREA OBS HAVE GONE LOW END OF GUIDANCE OR MAINLY UPPER 50S FOR LOWS...OR ONE MORE COMFORTABLE NIGHT BEFORE HUMIDITY RETURNS LATER IN WEEK. ..NICHOLS.. && .LONG TERM...(WEDNESDAY THROUGH NEXT TUESDAY)... MAJOR CHANGES HAVE BEEN MADE TO THE EXTENDED TO REFLECT WHAT WILL LIKELY BE OCCURRING. STRONG SOUTHWEST FLOW ON WEDNESDAY TO BOOST TEMPERATURES TO WELL ABOVE NORMAL FOR THIS TIME OF THE YEAR. THIS COMBINED WITH A LACK OF A TRIGGER WILL KEEP WEDNESDAY DRY. IMPRESSIVE COLD FRONT DIVING SOUTH AND SHOULD BE JUST ENTERING THE NORTHERN CWFA BY 12Z THURSDAY. SHOULD SEE SOME CONVECTION RIGHT ALONG THE FRONT BUT GIVEN THE STRONG WAA ALOFT...MOST PRECIP WILL BE POST FRONTAL. FRONT SHOULD BE JUST SOUTH OF I80 BY 18Z THURSDAY WITH IT NEARLY OUT OF THE CWFA BY 00Z FRIDAY. ALL MODELS SHOW STRONG CONSENSUS ON THIS TIMING. TEMPERATURES FOR THURSDAY WILL LIKELY REMAIN STEADY OR FALL FOLLOWING FROPA. A NICE GENERAL RAIN LOOKS TO BE IN THE WORKS FOR THURSDAY NIGHT INTO FRIDAY NIGHT. THIS WILL KEEP TEMPERATURES MUCH LOWER THAN PREVIOUSLY THOUGHT (ESPECIALLY FRIDAY). I STILL THINK I/M TOO WARM REGARDING MAX TEMPS FOR FRIDAY BUT HEADING IN THE RIGHT DIRECTION. ON SATURDAY...THE FRONT STARTS MOVING BACK NORTH. THE GFS IS PUSHING THE FRONT NORTH WAY TOO FAST AND IT SHOULD ONLY GET TO ABOUT THE WI/IL BORDER BEFORE STALLING AGAIN. THE FRONT SHOULD BEGIN MOVING SOUTH AGAIN SATURDAY NIGHT INTO SUNDAY. GLOBAL MODELS INDICATE THE REMNANTS OF RITA WILL BEGIN ARRIVING SUNDAY NIGHT. THIS MOISTURE COMBINED WITH ANOTHER STRONG COLD FRONT MOVING THROUGH THE AREA SHOULD BRING ANOTHER GENERAL RAINFALL TO THE REGION. ALTHOUGH WAY TOO EARLY TO TELL...THIS SECOND RAIN EVENT COULD PRODUCE SIGNIFICANT AMOUNTS. RAIN SHOULD SHUT OFF DURING THE DAY MONDAY AS COLD CANADIAN HIGH PRESSURE PUSHES THE FRONT SOUTH OF THE REGION. BASED ON THE 00Z ECMWF...TUESDAY MORNING SHOULD HAVE A CRISP FALL TOUCH TO IT WITH CHILLY TEMPERATURES. ...08... && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE. MO...NONE. && NICHOLS/08
