Might have to start taking this threat seriously as it's now less than 48 hours away

This is how I see the models in comparison to the GFS for wave 1

 

NAM/CMC/Euro Parallel: Slightly North

UKIE: South

Euro: Way North

 

Until I see some more consistency, not ready to commit to the SN/ZR threat. At this point its not a great chance IMHO just based on the narrowness of the band.

Over 150 water rescues in north-central KY and southern IN. Up to 8 inches of rain. Worst flash flooding here since March 1, 1997.

It's definitely a thread the needle event. A number of the GEFS are further to the north as well.

Even given the lower prob scenario, it would make for some shocked faces in the GTA if everything falls into place. The higher res guidance should help a lot, as they alluded to the north shift with that BZ band back in Feb I believe.

Made it to 66° here today with 0.11" of rain. 

 

Bo - probably safe to say you're going to have snow cover for a few weeks yet. Especially with you being in the shadier woods.

yeah, pretty common to have snow left in the wooded areas until Mother's Day and sometimes beyond.  I'm guessing this year,early may it will be gone... especially if these below normal temps continue.  Big difference from yesterday, with a high of 56... currently 23 and some light lake snow.  Most likely wont see 30 today.

That's crazy, the bad thing is the HPC 7 day QPF map shows widespread 4-5" more rain all around the same areas, and I wouldn't doubt that somebody gets way more than that if they get a tstorm train going again!

Going back a month some areas around here have seen in excess of 15 inches of precip. 6 weeks ago we were 4 inches behind on the year for precip and nearing a moderate drought. Now we are 6 inches above normal.

Lol, I take most of my vacations up to the UP. I have seen snow in the shady areas into the first week of June before a couple times. :D

I know!  When I came and met with the previous owner of this place, they told me they usually have snow in areas of the woods here then, but I was talking "snowcover".  May 1st last year, there was still 20"+ in my area... Don't think that will be the case this year obviously but, I know last year in early June there was areas of snow on my 20 acres still.  Makes for a very short Summer.

But that's ok.

two seasons in the UP... swat and shovel

Hardest hit areas of Louisville picked up another 1.5-2 inches of rain the last 2 hours. Storm totals are approaching 10 inches in spots. Flash-flooding rejuvenated.

What a crazy day in Louisville. Close to 6.50 inches of rain fell at my house and a major fire broke out at the General Electric Appliance Park sending plumes of ashes up in the air. I could see the smoke from my house and I live a good seven to 10 miles away.

 

Beargrass Creek is near my house and here's some photos I took this morning on my way to work. A lot of this had receded somewhat by the time I headed home. I've never seen the creek overflow its banks this bad.

sorry to hear about the flooding in KY.

 

I dont mind as much in the "off season" but the models have been just horrendous here w/ the first several rain events of spring. Far worse than in winter. Last night I was expecting a dousing rain and hoping it would end as snow (as models showed in far eastern MI) instead I got just a few light rain showers.

 

Cold morning, 25F at DTW.

Nice pics, Josh!

 

A beautiful Saturday morning in the north woods.  walked the perimeter of my land this morning and no snowshoes needed.  It's like walking on cement!  Saw some wolf tracks and a few bear tracks from when the snow was soft during the thaw.  No better way to wake up and start the day. :)

The NAM sucks lol. After 6 runs in a row of it showing 3-8" of snow around MBY tonight through Easter day, it caved to the GFS at 12z and only shows 2" or so. 2-3" would still get me close to average for the season though, I guess it will be another nowcast scenario like the monday night storm was where I got 4 inches in 4 hours.

SPC is showing probs for severe for Day 6.  Looks like something might be in the offing.  in their synopsis, the exact placement of where the severe weather lies is difficult to forecast right now, but it looks like some sort of outbreak, perhaps.

Some more for SPC, kind of odd to see something for a Day 6, but here's the synopsis.

DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0358 AM CDT SAT APR 04 2015

VALID 071200Z - 121200Z

...DISCUSSION...
LATEST RUNS OF THE MEDIUM-RANGE MODELS EXHIBIT DECENT AGREEMENT INTO
THE DAY 6 /THU. 4-9/ TIME PERIOD...PROJECTING THE WRN U.S. TROUGH TO
BECOME PROGRESSIVE AND TRAVERSE THE ROCKIES THROUGH DAY 5 BEFORE
SHIFTING INTO THE PLAINS DAY 6. FROM LATE IN THE DAY 6 PERIOD
ONWARD...SPREAD IN THE MODEL SOLUTIONS INCREASES SUCH THAT LOW
FORECAST CONFIDENCE PREVAILS DAYS 7 AND 8.

SEVERE-WEATHER RISK APPEARS RELATIVELY LOW EARLY IN THE PERIOD --
BUT A GRADUAL RAMP-UP IN RISK EACH AFTERNOON/EVENING THROUGH DAY 6
APPEARS LIKELY ACROSS THE U.S. AS THE WRN TROUGH APPROACHES -- AND
EVENTUALLY REACHES -- THE CENTRAL CONUS. THOUGH AIRMASS ACROSS THE
OK/ERN KS/MO/AR/N TX VICINITY DURING THE AFTERNOON ON DAY 4 /TUE.
4-7/ WILL LIKELY BECOME STRONGLY UNSTABLE...WEAK RIDGING PERSISTING
ALOFT -- AND ASSOCIATED/WEAK SUBSIDENCE -- SHOULD PERMIT CAPPING AT
THE BOTTOM OF THE EML LAYER TO PERSIST IN MOST AREAS. THIS SUGGESTS
THAT STORM INITIATION /AND ASSOCIATED SEVERE RISK/ SHOULD REMAIN
RELATIVELY ISOLATED.

SLIGHTLY MORE WIDESPREAD STORM DEVELOPMENT WILL BE POSSIBLE DURING
THE AFTERNOON ON DAY 5 /WED. 4-8/...AS WEAK HEIGHT FALLS BEGIN AHEAD
OF THE APPROACHING UPPER SYSTEM. WHILE EJECTION OF ANY APPRECIABLE
LEAD WAVE IS NOT EVIDENT ATTM...A LESS SUBSIDENT/MORE NEUTRAL
BACKGROUND LARGE-SCALE UVV SUGGESTS GREATER POTENTIAL FOR CAP
BREACHES/STORM INITIATION -- PRIMARILY ACROSS THE ERN KS/MO/OK
VICINITY. WITH STRONG INSTABILITY AND MODERATELY STRONG SHEAR
EXPECTED...ENVIRONMENT WILL FAVOR SUPERCELLS...AND ASSOCIATED RISK
FOR LARGE HAIL...DAMAGING WINDS...AND POSSIBLE TORNADOES.

WHILE ONGOING CONVECTION OVERNIGHT DAY 5 AND INTO EARLY DAY 6
LIKELY...ASCERTAINING DEGREE AND LOCATION OF SEVERE RISK DAY 6
PRESENTS SOME DIFFICULTY ATTM. WITH THAT SAID...THE ADVANCE OF THE
WRN TROUGH AND ASSOCIATED UVV INTO THE INTO THE CENTRAL PLAINS
DURING THE AFTERNOON AND EVENING WILL PERMIT WIDESPREAD CONVECTIVE
INITIATION -- FOCUSED INVOF THE COLD FRONT FORECAST TO BE ADVANCING
ACROSS ERN KS/CENTRAL OK NEAR PEAK HEATING. WITH SUBSTANTIAL
INSTABILITY LIKELY TO BE PRESENT AND A FAVORABLY SHEARED
ENVIRONMENT...A FAIRLY BROAD AFTERNOON AND EVENING ZONE OF RISK FOR
LARGE HAIL AND DAMAGING WINDS ALONG WITH A FEW TORNADOES IS EVIDENT
-- EXTENDING FROM IL SWWD ACROSS MO/AR INTO SERN KS/ERN OK AND
POSSIBLY INTO N CENTRAL/NERN TX.

If Tuesday's event is any sign (as the models overcorrected southward with that frontogenesis band of snow also), I think you're good.
