Area forecast discussion, Oct 3, 2:45 PM CDT, 8 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 245 PM CDT TUE OCT 3 2000 LATEST SURFACE ANALYSIS INDICATING LOW PRESSURE OVER S CENTRAL KS...WITH THE WARM FRONT ACROSS KANSAS CITY EAST TO JUST NORTH OF ST LOUIS. PRESSURE FALL INDICATE THAT THE LOW CENTER SHOULD CONTINUE TO MOVE SLIGHTLY NORTH OF ALONG THE FRONT...DRAGGING THE FRONT NORTH MORE TOWARDS THE CWA. WITH GOOD HEIGHT RISES BEHIND A TROUGH/FRONT MOVING ACROSS SRN MN AND S DAKOTA SE INTO IA...THE FRONT MAY NOT MAKE IT MUCH FURTHER NORTH. UPPER AIR CHARTS SHOWING THE 850 FRONT ACROSS SRN IA BORDER...WITH GOOD DRY AIR MOVING IN BEHIND. COLDER AIR STILL LAGGING ACROSS CANADA. MID LEVELS SHOWING GOOD CONVERGENCE ACROSS THE SAME AREA WHERE THERE IS GOOD CLOUDINESS ACROSS SOUTHERN MN AND SOUTH DAKOTA. STRONGEST PART OF THE JET IS EXTENDING FROM NRN MN ACROSS GREAT LAKES. THIS SHOULD PULL A GOOD AREA OF DIVERGENCE OVER THE CWA THIS EVENING... WHICH SHOULD SERVE TO ENHANCE PRECIP ONGOING IN THE AREA. WV SATELLITE IMAGERY INDICATING THE NEXT SHORTWAVE NOW MOVING ACROSS WASHINGTON AND SRN BRITISH COLUMBIA. 12Z MODELS SEEM TO HAVE INITIALIZED FAIRLY WELL...WITH THE ETA DOING THE BEST ON THE SURFACE FRONT AT THIS TIME...AS WELL AS A FEW OTHER SMALLER FEATURES. AVN BEGINS TO DIVERGE WITH THE SPEED OF THE NEXT SIGNIFICANT SHORT WAVE...BECOMING SLOWER AND MORE AMPLIFIED BY WEDNESDAY NIGHT...WHICH DELAYS THE ONSET OF THE PRECIP. FOR NOW... PREFER THE FASTER MOVING ETA/NGM. AT THE SURFACE THINK THAT THE NGM BRINGS THE SURFACE FRONT TOO FAR NORTH TONIGHT...THE NORTHERN TROUGH IS ALREADY BEGINNING TO DEPRESS THE FRONT SOUTH. ETA IS INDICATING THAT THE SURFACE FRONT SHOULD BE AT ITS MOST NORTHERN POSITION SOMETIME THIS AFTERNOON...AND IS ALREADY SINKING SOUTH AGAIN AT 00Z. FWC NUMBERS MAY NOT BE TOO BAD LATER IN THE FORECAST. TONIGHT...LLJ...MOISTURE...JET DYNAMICS...AND SHORTWAVE WILL FINALLY COME TOGETHER TO CAUSE MORE PRECIP ACROSS THE AREA TONIGHT...WITH A GOOD AREA OF MORE STRATIFORM PRECIP ACROSS THE NORTH...AND SOME THUNDER SOUTH. BIG QUESTION WILL BE IN THE TIMING OF THE PRECIP. FIRST WAVE SHOULD BE WITH THE CONVECTION NOW DEVELOPING OVER SOUTHWEST IOWA...AND THEN AGAIN WITH THE WAVE NOW MOVING OUT OF THE ROCKIES...WHICH SHOULD MOVE OVER THE AREA BETWEEN MIDNIGHT AND 6 AM. ITS LOOKING MORE LIKE TWO WAVES OF PRECIP OVERNIGHT...WITH ONE EARLY WITH THE THUNDER...AND AGAIN BETWEEN MIDNIGHT AND 6 AM MAINLY AS LIGHT RAIN. AM GOING TO DOWNPLAY THE SEVERE THREAT...IF IT DOES OCCUR IT SHOULD BE WITH THE SOUTHERN 2-3 TIERS OF ZONES...AND WOULD BE MORE HAIL THAN ANYTHING ELSE. TEMPS IN THE GOING FORECAST LOOK GOOD. WEDNESDAY...EXPECT SOME EARLY MORNING LINGERING PRECIP...MAINLY EAST. DONT EXPECT TO GO WITH MORE THAN SCATTERED POPS...SLIGHTLY HIGHER EAST. HIGHS STILL LOOKING GOOD...WITH SIMILAR NUMBERS IN GOING FORECAST AND CURRENT GUIDANCE. WILL STAY CLOSE. A GOOD BAND OF MOISTURE REMAINS OVER THE AREA...AND WILL GO WITH A MOSTLY CLOUDY WORDING FOR ALL ZONES. WEDNESDAY NIGHT...ANOTHER GREAT CHANCE OF PRECIP MOVING IN...WITH THE CATEGORICAL POPS MAKING ANOTHER APPEARANCE MOST ZONES. WORDING FOR PERIODS OF RAIN LOOKS GOOD. LOWS RANGING IN THE 40S SHOULD BE GOOD... JUST SLIGHTLY COOLER THAN TONIGHT. THURSDAY...THE PRECIPITATION CONTINUES AS THE SURFACE WAVE MOVES ACROSS MO INTO IL...BUT WILL ONLY GO WITH THE CATEGORICAL POPS SOUTH...AND LIKELY POPS NORTH. RATHER COOL HIGHS NEEDED...AND WILL BACK OFF FROM THE TEMPS IN GUIDANCE...BUT PROBABLY NOT AS COOL AND CURRENT ZONES. THURSDAY NIGHT...COOL AIR BEGINS TO MAKE IT INTO THE AREA...BUT WITH THE STRONG LAYER OF MOISTURE...FEEL THAT CLOUDS MAY KEEP TEMPS WARMER THAN PREVIOUSLY THOUGH...THOUGH CURRENT ZONES SHOULD ONLY NEED A LITTLE TWEAKING FOR LOCATION OF COLDEST TEMPS AND RANGE ACROSS THE REGION SHOULD BE A LITTLE LARGER. EXTENDED...FRI-SUN PROBLEM THIS TIME FRAME IS HOW SLOWLY TO MOVE OUT THE LARGE UPPER LEVEL TROUGH. THE EXTENDED MODELS ARE COMING MORE INTO AGREEMENT... ESPECIALLY IN KEEPING THE AREA UNDER THE INFLUENCE OF THIS TROUGH INTO THE MONDAY/TUESDAY TIME FRAME. AS LARGE AS IT DEVELOPS THIS WEEK I AM NOT OVERLY SURPRISED. AT THIS TIME WILL PUT PRECIP INTO FRIDAY... GENERAL CHANCE FROM NORTHEAST ZONES...AND SLIGHT CHANCE EARLY FOR SOUTHWESTERN ZONES. AS FOR TEMPS...FEEL FMR IS FAR TOO COOL... ESPECIALLY FOR SATURDAY MORNING. IN MODELS WHERE LL MOISTURE IS AVAILABLE...INDICATIONS ARE THAT WE SHOULD BE IN LOW CLOUDS THROUGH MOST OF THE WEEKEND...PERHAPS BREAKING OUT ON SUNDAY SOMETIME. FMR MUST BE PROGGING GOING CLEAR BY FRIDAY NIGHT. WHILE 850 TEMPS ARE DOWNRIGHT WINTER LIKE...THINK THAT THIS WILL JUST CONTRIBUTE TO THE CLOUDINESS... AND WE WONT HAVE A CHANCE TO RADIATE OUT TO THE ADVERTISED TEMPS. WILL RAISE TEMPS IN GOING FORECAST...AGAIN. .DVN... IA...NONE. IL...NONE. MO...NONE. LRE
