DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1119 AM CDT FRI MAY 07 2010

VALID 071630Z - 081200Z

...THERE IS A MDT RISK OF SVR TSTMS OVER PORTIONS OF INDIANA AND
OHIO...

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE ARKLATEX INTO THE
UPPER OH VALLEY...

...OH VALLEY...
A STRONG PROGRESSIVE SHORTWAVE TROUGH OVER SD/NEB WILL TRACK EASTWARD TODAY...WITH ITS ASSOCIATED 100+ KNOT MID LEVEL JET NOSING ACROSS THE UPPER MIDWEST AND INTO THE GREAT LAKES REGION. A LARGE FETCH OF SOUTHERLY LOW LEVEL WINDS WILL RAPIDLY TRANSPORT GULF MOISTURE NORTHWARD AND HELP TO DESTABILIZE A LARGE PORTION OF THE MID/LOWER MS...OH...AND TN VALLEYS.

SCATTERED THUNDERSTORMS ARE ONGOING THIS MORNING ACROSS LOWER MI TO THE NORTH OF THE SURFACE WARM FRONT. THIS ACTIVITY IS EXPECTED TO LIFT AWAY FROM THE WARM SECTOR AND ALLOW STRONG HEATING MUCH OF THE DAY ACROSS IL/IND/OH. PRESENT INDICATIONS ARE THAT THUNDERSTORMS WILL INITIATE BY MID-LATE AFTERNOON NEAR SURFACE LOW OVER EASTERN IL/NORTHWEST IND. STORMS WILL LIKELY RACE EASTWARD ACROSS THE MODERATE RISK AREA THROUGH THE LATE AFTERNOON AND EVENING WITH THE RISK OF WIDESPREAD DAMAGING WINDS AND HAIL. LOW LEVEL VERTICAL SHEAR IN VICINITY OF THE WARM FRONT WILL ALSO BE CONDUCIVE FOR SUPERCELLS AND A FEW TORNADOES.

I was out in Perrysburg this morning and have never seen clouds like the ones hanging overhead about 9:30 a.m. today. They were huge and rippled looking, like something out of a movie just before the clouds open up and the alien ships appear.

Updated the original post with some more links and graphics. Current observations have a developing CU (cumulus) field through Indiana and far western Ohio where the sun is able to help get things baking. Short term model guideance has convection initiating in the next 2-3 hours in Indiana moving into Ohio 1-2 hours later. Forecast instability at the time will be sufficient for some higher end severe activity, but wind profiles should keep the tornado threat down a bit. However, should any local areas of enhanced shear develop that will be moot. Wind profiles do scream a very high widespread damaging wind event. So do not be shocked to see reports of 70-80 mph with the stronger storms.

So, in normal peoples terms, are we expecting heavy downpours?

posted by draven4099 on May 07, 2010 at 02:10:49 pm     #  

Puts me in mind of Texas Flood

posted by madjack on May 07, 2010 at 02:18:17 pm     #  

LOL Sorry. Forgot you all aren't really exposed to this all that often. Here, local TV weather can get fairly technical and everyone has an idea of what they mean...even though I tried to avoid that as much as possible.

This situation, heavy downpours really should not be your concern. The main threats right now appears to be hail 1-2" in diameter, a few tornadoes (should remain below EF2), and widespread wind damage with winds well over 70 mph in most storms.

In other words, think out of the normal terms you are use to hearing from the rejects you have doing local weather there (well besides WTVG - for the most part).

NWS STORM PREDICTION CENTER NORMAN OK
0159 PM CDT FRI MAY 07 2010

AREAS AFFECTED...PARTS OF NRN IND...SERN LWR MI...AND NRN OH

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 071859Z - 072030Z

THE RISK FOR SEVERE STORMS APPEARS LIKELY TO INCREASE WITHIN THE NEXT FEW HOURS. A TORNADO WATCH MAY BE NEEDED WITHIN THE NEXT HOUR OR SO.

RAPID DESTABILIZATION IS ONGOING ALONG A RETREATING WARM FRONT EXTENDING TO THE EAST OF A SURFACE LOW NOW IN THE PROCESS OF MIGRATING ACROSS EAST CENTRAL ILLINOIS INTO NORTHERN INDIANA.
STRONGEST NEAR SURFACE THERMAL/MOISTURE ADVECTION CURRENTLY APPEARS FOCUSED ACROSS NORTHEAST INDIANA/NORTHWEST OHIO INTO SOUTHEASTERN LOWER MICHIGAN...WHERE RAPID SURFACE PRESSURE FALLS ARE ONGOING.
THIS FORCING APPEARS LIKELY TO GRADUALLY SHIFT EAST NORTHEASTWARD TOWARD THE LOWER GREAT LAKES REGION THROUGH THE REMAINDER OF THE AFTERNOON HOURS...AS AN INTENSIFYING 500 MB JET STREAK NOSES EASTWARD OUT OF THE CENTRAL PLAINS. AS THIS OCCURS...AND WEAK MID-LEVEL COOLING CONTRIBUTES TO ERODING INHIBITION...INCREASING AND INTENSIFYING CONVECTIVE DEVELOPMENT IS ANTICIPATED. THE BULK OF NEW STORMS MAY INITIALLY FORM TO THE COOL SIDE OF THE WARM FRONT...BUT ACTIVITY MAY DEVELOP IN CLOSER PROXIMITY TO THE WARM FRONTAL ZONE...PERHAPS SOUTHWARD INTO THE WARM SECTOR...AS EARLY AS 21-22Z.

IN THE PRESENCE OF STRONGLY SHEARED...40-50 KT SOUTHWESTERLY DEEP LAYER MEAN FLOW...AND MIXED LAYER/MOST UNSTABLE CAPE IN EXCESS OF 1000 J/KG...CONDITIONS WILL BE SUPPORTIVE OF SUPERCELLS. IT IS STILL A BIT UNCLEAR WHETHER CONVECTION WILL QUICKLY GROW UPSCALE INTO A SEVERE MESOSCALE CONVECTION SYSTEM...OR TEND TO REMAIN DISCRETE IN NATURE...BUT HIGHEST POTENTIAL FOR TORNADOES IS EXPECTED TO EXIST IN STORMS FORMING WITHIN THE FRONTAL ZONE. IT APPEARS STORM MOTION COULD PARALLEL FRONT...WHICH COULD ALLOW FOR AN ISOLATED STRONG TORNADO...BEFORE A TRANSITION TO PRIMARILY DAMAGING WINDS TAKES PLACE LATER THIS EVENING...FARTHER TO THE EAST.
OTHERWISE...LARGE HAIL IS ALSO LIKELY IN STRONGEST STORMS.

Any Gabrielson of SevereStudios is on the severe cell moving into Ohio. Nothing really all that big. Some low hanging stuff, but it is detached from the base ofe the cell so really nothing to worry about for right now. Some upward motion, but the storm still isn't in a very favorable configuration yet.

I'm using GRLevel 2 Analyst Edition. http://www.grlevelx.com

It's used by nearly every NWS office in the plains now and also several TV stations. Extremely powerful radar program that chasers and consumers can get without shelling out a ton.

Tornado warned cell in Henry county continues to look rather unimpressive. However, it is also in an area that is almost 80 miles from the nearest radar site, so the view of it isn't all that clean. Nothing spotted by any the dozen or so chasers that are on it right now.

AREAS AFFECTED...ERN IND...OH AND WRN PA

CONCERNING...TORNADO WATCH 143...

VALID 072325Z - 080100Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 143 CONTINUES.

A SEVERE THREAT WILL PERSIST ACROSS NRN OH THIS EVENING AND MAY DEVELOP SWWD ACROSS CNTRL OH INTO SRN IND. A FEW TORNADOES...LARGE HAIL AND ISOLATED WIND DAMAGE WILL BE POSSIBLE. AS THE STORMS MOVE INTO NE OH...WW 143 WILL LIKELY BE EXTENDED.

A CLUSTER OF SEVERE STORMS IS ONGOING FROM NW OH NWD ACROSS LOWER MI ON THE NOSE OF A 40 TO 50 KT LOW-LEVEL JET. THIS FEATURE ALONG WITH STRONG DEEP LAYER SHEAR IS CREATING A FAVORABLE ENVIRONMENT FOR SUPERCELLS. THE LATEST WSR-88D VWP FROM CLEVELAND SHOWS ABOUT 70 KT OF 0-6 KM SHEAR AND 0-3 KM HELICITY OF 500 M2/S2. THIS SHEAR ENVIRONMENT SHOULD SUPPORT A TORNADO THREAT EWD ACROSS MUCH OF NRN OH AS THE SUPERCELL IN WOOD COUNTY MOVES EWD AT 50 KT REACHING THE CLEVELAND AREA BY 0130Z. IN ADDITION...THE 18Z SOUNDING FROM WILMINGTON SHOWS A 850 TO 500 MB LAPSE RATE AROUND 7.0 C/KM WHICH ALONG WITH THE STRONG VERTICAL SHEAR SHOULD SUPPORT A THREAT FOR LARGE HAIL. VERY LARGE HAIL MAY OCCUR WITH THE MORE DOMINANT SUPERCELLS. A WIND DAMAGE THREAT MAY DEVELOP ESPECIALLY IF A LINE CAN ORGANIZE.

Storm with the tornado warn shows a pretty high base with no lowerings at all. Probably something that should have been left alone for a bit as hail and damaging winds are the main threats.

Watching the 13ABC coverage online...I feel sorry for you folks with the quality of weather coverage. LOL

posted by toledoinmd on May 07, 2010 at 09:39:55 pm     #  

Linecrosser - Well the velocity images of the radar aren't going to display the hook imagery you are talking about. Also the storms today really weren't in ideal configuration. Going to use probably the best example in history we have right now, the strongest tornado that was actually measured.

You can see the perfect hook echo formation on base reflectivity.

Base velocity is only going to show wind speeds and direction.

Of course for kicks...here are some 3D images from the same system showing the internal rotation at all levels and the 3D representation of the higher end echoes.

My wife and I waited out the storm in our car in the old Crane Creek parking lot along Lake Erie after birdwatching at the Magee Marsh boardwalk. The storm made me a little nervous for a bit. Visibility dropped to nearly zero from the torrential rainfall that blasted by in horizontal sheets. The strong winds rocked the car and caused the barely visible nearby trees to dance a little too much. Small hail fell for a short time. Debris whipped by. Afterwards, the parking lot was littered with small tree branches. The one side of my car was plastered with green leaves ripped from the trees. The rainfall intensity was amazing. That was the strongest storm I've seen since the one in June 2008 that toppled our neighbor's mature red oak tree into our front yard.
