12Z looks to be a south of I-70 drencher:  http://www.wpc.ncep.noaa.gov/qpf/p168i.gif?1467401621

 

WPC holding steady(no north shift)

 

CENTRAL PLAINS EASTWARD INTO THE MID MISSISSIPPI VALLEY  

 

THERE CONTINUES TO BE ABOVE AVG MODEL AGREEMENT THAT A HEAVY TO  

POTENTIALLY EXCESSIVE RAIN EVENT WILL UNFOLD ACROSS KS (AND  

POSSIBLY SOUTHERN NE AND NORTHERN OK) EASTWARD INTO MISSOURI  

TONIGHT INTO SATURDAY AS THE COMBINATION OF S/WV ENERGY EJECTING  

SLOWLY EASTWARD OUT OF CO INTERACTS WITH INCREASING LOW-LEVEL JET  

AND POOLING OF 1.75 TO 2.0 INCH PWS ALONG AND NORTH OF A  

QUASI-STATIONARY W-E FRONTAL BOUNDARY NEAR THE KS/OK BORDER. THE  

CONSENSUS OF 12Z GLOBAL GUIDANCE CONTINUES TO LIE NORTH OF THE  

HIGH-RES ENSEMBLE MEAN. WPC MAINTAINED CONTINUITY FROM THE  

PREVIOUS FORECAST IN TERMS OF KEEPING THE AXIS OF HEAVIER RAIN  

SOUTH OF THE GLOBAL ENSEMBLE MEAN AND (THUS) MORE CLOSELY TIED TO  

THE HIGH-RES CONSENSUS...WHICH IS WITHIN A MORE FAVORABLE  

DEEP-LAYER INSTABILITY PROFILE AND CLOSER TO (NOT FAR NORTH OF)  

THE SURFACE BOUNDARY. A ROBUST S-SW LLJ TONIGHT (50-55 KTS) INTO  

THIS LOW LEVEL BAROCLINIC ZONE WILL FAVOR INCREASED SOUTHWARD  

(UPWIND) PROPAGATION OVERNIGHT AS THE MCS CONTINUES TO  

DEVELOP/EXPAND....WHICH WILL FAVOR SOME TRAINING OF CELLS THROUGH  

THE EARLY-MID MORNING HOURS ON SAT. A STRIPE OF 1.5 TO 3 INCH  

AREAL AVG RAINS ARE EXPECTED ACROSS CENTRAL TO EAST-CENTRAL  

PORTIONS OF KS...THOUGH AS PER THE HIGH-RES CAM GUIDANCE...  

LOCALIZED TOTALS OF 4-5+ INCHES ARE CERTAINLY POSSIBLE.

but north of 12z

 

north trend continues(is this winter LOL)

 

18Z GFS seems to have two waves of precip 1st wave is A HAIR more north the second one more south closer to the 12z precip

I have been thinking the same thing as the models show significantly different tracks and flopping like a fish out of water. I've always thought models were more consistent with summer systems. A lot of moisture to work with, so there may be some forecast busts. Not good on a holiday weekend.

Yeah, it's gonna really put a damper (literally) on some people's holiday plans.

Still have the significant discrepancy with the 4 km run.

 

Yeah the 4km has the QC receiving <0.1" of rain, while the 12km dumps 5-6" lol.  This time of year I would go with the southern solutions, as the deep convection will likely hug the instability gradient further to the south.  12km precip output doesn't look very realistic considering even it keeps the instability fairly far south.

2009 was nasty

0.81 of rain that day in Springfield, and 71/65 the H/L extremes that day.

 

But 7/4/2009 pales in comparison to 7/4/1981 here in Springfield--exactly one calendar cycle to the day of the awful 4th of 2009.  The wettest 4th of July on record: 3.00 inches of rain.  However, the temps were almost a replica of 2009: 75/69 here on 7/4/81.

models have trended back south at the last minute and looking at trends seems to conform

 

I-70 in MO i think is most at risk for flooding

 

1-3 inches from I-70 south to lake of the Ozarks fell during the day

 

if the train sets up there could be bad since lots of hilly terrain and outdoor campers
