June 21st and beyond heavy rain thread


A-L-E-K

Recommended Posts

Picked up 0.73" with the storms that rolled in just after midnight.  That bumps us up to 7.42" for the month too. 

 

I was talking to a farmer about the corn crop yesterday, and he was astounded at how fast the corn was growing.  He said it's been growing at 4" per day for the past few weeks, and will be ready to tassel in the next week or two.  This is ahead of schedule, which is pretty damn impressive given such a late start to the growing season.  There have been a few fields that have been impacted by some standing water, but even with the 7"+ rain so far this month most of the water actually soaked in pretty nicely in most areas. 

Would have to think the warm days/night and a good amount of sun/dry time has helped offset the heavy rain totals. I'm sure the outcome would be different if it had been cooler.

Yeah that definitely helped.  Today's 4-6" that fell over the area may sting a little however.  Hopefully since the crop is far enough along if there's any standing water for a short amount of time it won't impact things too negatively.  Of course the fields that will go under water near the flooding rivers will be a different story.

I know it's fairly early in the game....but cells seem to be firing a good 30 to 40 miles south of recent guidance (for now)....the train may shift south a bit compared to guidance

 

 

south has always been the way to go but the heaviest fell south overnight so :yikes:

I'm really hoping so. We've had over 3" in the last week here, low spots are really mushy still. Thus far, we haven't had any flooding issues (had 20" in the lower level in May!) and I really don't want to deal with it again. I have redone the sump with two 3/4HP pumps, the main on a pressure switch with another on a float switch a bit higher than the top of the main in case it gets overwhelmed. Our sump pit can get a heck of a lot of water coming in it when it rains heavy.

Best of luck Boog's!

 

PWAT's exploding over southern Iowa (as forecasted) .... 2.1+ with a solid 850 feed right into N IL now

 

hopefully the channel can set up north of the those that got hammered this morning alek.....but it's gonna be tight...not a lot of wiggle room...and unfortunately, the wiggle room takes it right into the heart of the metro

MESOSCALE PRECIPITATION DISCUSSION 0192
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
620 PM EDT SAT JUL 12 2014

AREAS AFFECTED...EXTREME SOUTHEAST NE...CENTRAL/SOUTHERN IA...FAR
NORTHERN MO...CENTRAL/NORTHERN IL...EXTREME SOUTHEAST WI

CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE

VALID 122210Z - 130215Z

SUMMARY...CONVECTION WILL DEVELOP AND INCREASE IN COVERAGE AND
INTENSITY THE NEXT FEW HOURS OVER THE MIDWEST. POTENTIAL FOR
CELL-MERGERS AND TRAINING CONVECTION WILL HEIGHTEN THE FLASH FLOOD
POTENTIAL.

DISCUSSION...THE LATEST VIS SAT IMAGERY SHOWS AN EXPANDING CU/TCU
FIELD IN THE WARM SECTOR AHEAD OF A SYNOPTIC SCALE COLD
FRONT...AND AHEAD OF LARGER SCALE HEIGHT FALLS IMPINGING ON THE
UPPER MIDWEST FROM SRN CANADA. THE BOUNDARY LYR IS VERY WARM AND
UNSTABLE WITH SBCAPE VALUES AHEAD OF THE COLD FRONT OF 4000 J/KG
TO 4500 J/KG. MID LEVEL LAPSE RATES ARE NOT PARTICULARLY
STEEP...BUT STRONGER LOW LEVEL LAPSE RATES AHEAD OF THE FRONT
COUPLED WITH IMPROVING LARGER SCALE ASCENT ALOFT SHOULD BE ENOUGH
TO ALLOW CONVECTION TO DEVELOP AND EXPAND IN A LINEAR FASHION
SW/NE ALONG AND AHEAD OF THE FRONT.

THE CONVECTIVE MODE BASED ON THE AFOREMENTIONED SBCAPE VALUES AND
EFFECTIVE BULK SHEAR VALUES OF 35 TO 45 KTS SHOULD SUPPORT AN
INCREASE IN MULTI-CELLULAR AND SUPER-CELLULAR CONVECTION THE NEXT
COUPLE OF HOURS. THE ENVIRONMENT THIS EVENING WILL INITIALLY FAVOR
CELL-MERGERS...BUT SHOULD BECOME INCREASINGLY FAVORABLE FOR
TRAINING CONVECTION...ESP AFTER 00Z GIVEN THE MEAN LAYER FLOW
PARALLELING THE COLD FRONT...AND WITH THE NOSE OF A VERY MOIST 40
KT SWLY LOW LVL JET ARRIVING BY AROUND 00Z.

ALL OF THE GLOBAL MODELS AND THE LATEST HI-RES MODELS STRONGLY
SUPPORT MORE ORGANIZED CONVECTION DEVELOPING OVER THE NEXT FEW
HOURS...WITH A HEIGHTENED RISK OF TRAINING CONVECTIVE LINE
SEGMENTS AFTER 00Z.

FFG VALUES ARE LOCALLY RATHER LOW...AND WITH PWATS EXPECTED TO
INCREASE TO NEAR 2 INCHES THIS EVENING...RAINFALL RATES OVER 2
INCHES/HR WILL BE EXPECTED. THIS COUPLED WITH POTENTIAL FOR
TRAINING CONVECTIVE BANDS WILL ELEVATE THE RISK FOR FLASH FLOODING.

NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
511 PM CDT SAT JUL 12 2014

.MESOSCALE DISCUSSION...
510 PM CDT

STORMS ARE INITIATING ACROSS SOUTHERN AND EASTERN IA AND HAVE
PROMPTED THE ISSUANCE OF A TORNADO WATCH THAT EXTENDS AS FAR EAST
AS NORTHWEST IL. LATEST HAND SURFACE ANALYSIS INDICATES A POOL OF
75+ DEW POINTS ACROSS SOUTHEAST IA INTO CENTRAL IL ADVANCING
NORTHWARD WITH MANY SURFACE OBS IN THIS AREA INDICATING
GUSTINESS. AT THE LEADING EDGE OF THIS A WARM FRONT WITH STRONG
MOISTURE CONVERGENCE IS INCHING NORTHWARD NEAR INTERSTATE 88
AHEAD OF A 1012MB SFC LOW IN CENTRAL IA. SUCH A SETUP OF A SLOWING
NORTHWARD-MOVING WARM FRONT AHEAD OF A NOT-TOO-STRONG LOW PRESSURE
WITH GOOD REPLENISHING MOISTURE REALLY SPELLS TROUBLE FOR HEAVY
RAINFALL TONIGHT WITHIN THE REGION. MOST FAVORED THIS EVE WOULD BE
ALONG AND IMMEDIATELY NORTH OF THIS WARM FRONTAL AXIS...SO THE
NORTHERN FORECAST AREA INCLUDING ROCKFORD. AS CONVECTION
EVOLVES/EXPANDS EASTWARD THROUGH MID-LATE EVENING...SOME
SOUTHWARD PROGRESSION IS THEN LIKELY INTO OVERNIGHT. SO THE ENTIRE
AREA REMAINS UNDER AN INCREASING RISK FOR HEAVY RAINFALL CAPABLE
OF FLASH FLOODING...WHICH OBSERVATIONAL TRENDS SUPPORT.

The outline area is only further south because of another md they issued earlier for areas north of this one

 

I see what you're saying.  The quote below was odd to read from the disco you mentioned considering the one I posted came out just a few minutes later....

 

EDIT:  nevermind....the disco you mentioned was from over 2 hours ago....who know's....we'll see

 

 

THE 12Z ECMWF AND 12Z GFS MODELS TEND TO HAVE A SOMEWHAT BETTER

HANDLE FOR THE TIME BEING ON THE EXPECTED AXIS OF

CONVECTION...WITH THE 12Z NAM...12Z ARW AND 12Z NMMB ALL LIKELY

TOO FAR SOUTH AT LEAST IN THE SHORT TERM.

IDK, setup doesn't scream heavy rain to me right now

 

LLJ should begin kicking in over the next few hours (RAP has a 925-850mb winds of 40-45kts developing after Midnight here). 

 

That's going to help with getting more of those water-logged boomers to pop up, despite the somewhat marginal instability.

of course but the warm front isn't going to get hung up like i thought earlier…convection will be transient

Rainfall rates of 1-2" per hour with those storm rolling into NW IL.

 

Heavy corridor or rain is going to lay down between MKX and RAC.

 

Edit: Racine County is going to pick up a good deal of rain in the next few hours.

MESOSCALE PRECIPITATION DISCUSSION 0194
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
955 PM EDT SAT JUL 12 2014

AREAS AFFECTED...NORTHEAST MO...SOUTHEAST IA...CENTRAL/NORTHERN
IL...SOUTHEAST WI...SOUTHWEST MI...NORTHWEST IN

CONCERNING...HEAVY RAINFALL...FLASH FLOODING LIKELY

VALID 130150Z - 130620Z

SUMMARY...CONVECTION WILL CONTINUE TO DEVELOP AND REMAIN WELL
ORGANIZED WHILE ADVANCING EAST ACROSS THE MIDWEST THE NEXT FEW
HOURS. POTENTIAL FOR CELL-MERGERS AND TRAINING CONVECTION WILL
SUSTAIN A FLASH FLOOD THREAT.

DISCUSSION...THE LATEST IR SAT IMAGERY SHOWS MULTIPLE LINEAR BANDS
OF STRONG COLD-TOPPED CONVECTION AND A FEW SUPERCELLS EXTENDING
FROM SERN IA NEWD ACROSS NRN IL AND INTO SERN WI AS A COLD FRONT
ADVANCES SEWD INTO THE REGION. THE ACTIVITY IS INTERACTING WITH A
MODERATELY UNSTABLE BOUNDARY LYR AHEAD OF THE FRONT WITH MUCAPE
VALUES OF 2000 J/KG TO 3000 J/KG...ALONG WITH A SWLY LOW LEVEL JET
OF 40 TO 50 KTS WHICH IS HELPING TO TRANSPORT VERY MOIST AIR NEWD
AHEAD OF THE FRONT. IN FACT...THE LATEST THE GOES-SOUNDER AND GPS
DERIVED PWATS SHOW A POOL OF 2 INCH PWATS OVER CNTRL/SERN IA AND
INTO NWRN IL ATTM.

ALL OF THE GLOBAL MODELS AND THE LATEST HI-RES MODELS STRONGLY
SUPPORT A CONTINUATION OF ORGANIZED CONVECTION OVER THE NEXT FEW
HOURS...EXTENDING DEEPER INTO CNTRL/NRN IL...SERN WI...SWRN LWR MI
AND EVENTUALLY NWRN IN BY 06Z IF NOT SOONER. THE SUSTAINABILITY OF
THE CONVECTION WILL BE HIGHLY DRIVEN BY AN INCREASING SWLY LOW LVL
JET OVERNIGHT AHEAD OF THE FRONT AND AHEAD OF STRENGTHENING HEIGHT
FALLS ASSOC WITH AN AMPLIFYING UPR TROUGH OVER THE UPR MIDWEST.
GLOBAL MODELS SUPPORT 2 INCH PWATS AND OVER 50 KTS OF LOW LVL JET
OVERNIGHT PROVIDING RATHER STRONG ALBEIT SOMEWHAT ELEVATED
THERMODYNAMICS. RAINFALL RATES SHOULD REMAIN HIGH AT UP TO 2
INCHES/HR AND WITH THE EXPECTATION OF ADDITIONAL CELL-MERGERS AND
CELL TRAINING...THERE WILL REMAIN AN ELEVATED THREAT FOR FLASH
FLOODING.

FFG VALUES ARE LOCALLY RATHER LOW...ESP NEAR AND SOUTH OF
KORD...SO THIS WILL ONLY ENHANCE THE FLASH FLOOD THREAT. WILL
CONTINUE TO MONITOR.

Grand Rapids area looks to be getting the training t'storms right now.

 

Looks like an easy 2"+ of rain along that corridor, based on what's fallen over Lake Michigan.

Yeah, I've been watching that. I'm hoping the worst keeps trending to the NE, toward the Bay, but at least some of that will come through FNT, I'm just hoping for not much over an inch.
