Severe T-Storm Warnings

March 12th, 2012 at 12:25 pm by under Bill's Blog, News, Weather

  4:20 PM:  Dang, I just took a call from someone who wanted to know if the time change was supposed to be last weekend!!!   Severe T-Storm Warnings for Montcalm, Mecosta, E. Newaygo, Clare and Osceola Counties for marginal hail and wind.   Check the Fremont Cam.   3 reports of pea-sized hail from the Muskegon area.  Also hail at Stony Lake when the storm went thru (Oceana Co.)  Pea-sized hail and gusts to 40-50 mph in Whitehall.  Update from GRR:  ” Checked with Benona Shores Golf Course near Little Sable Point, they had Estimated 30 mph wind gust with pea size hail that fell from the storm…quick mesoscale update:  still have rather extensive cloud cover and very marginal instability. the storm prediction center is not thinking a watch will be necessary anytime real soon, however there is still potential for a few strong to severe storms by late aftn/eve.”  Bill adds – seeing the potential for (as of now) small hail and a below-severe criteria gust front with the storms coming into NW Muskegon and Oceana Co.  A small bowing segment went thru N. Oceana Co. – leave a comment if you had some wind up there. The Storm Prediction Center has issued a meso-discussion for N. Illinois, N. Indiana and SW Michigan.  Severe Thunderstorm or Tornado Watch Possible.  Golfball-sized hail already near Racine WI – storm tracking over Lake Michigan now.  Hail also reported west of Chicago.  Special Marine Warning for Holland north.  Significant Weather Advisory for Oceana/Muskegon.  North of a line from Grand Haven to Mt. Pleasant.  T-Storms…not a ton of lightning, but some – certainly a chance of gusty winds and hail.  Chance of a tornado in this area is not zero, but pretty small as of now.  They say:  “PRESENT INDICATIONS ARE THAT SOME FORM OF THIS IL CONVECTION WILL PERSIST INTO THE AFTERNOON WHILE DEVELOPING NEWD TO EXTREME SE WI/SRN LAKE MI…AND EWD TOWARD SRN LOWER MI. THE MODEST INSTABILITY WILL COMBINE WITH STRONG DEEP-LAYER SHEAR /EFFECTIVE BULK SHEAR AOA 50 KT/ AND EFFECTIVE SRH OF 150-250 M2/S2 TO SUPPORT A RISK FOR BOTH SUPERCELLS AND BOWING SEGMENTS…WITH AN ATTENDANT RISK FOR DAMAGING WINDS AND A COUPLE OF TORNADOES. THE PRIMARY SEVERE RISK IS EXPECTED TO BEGIN BY 21Z AND PERSIST UNTIL ROUGHLY 03Z. DAMAGING WIND THREAT SHOULD SLOWLY INCREASE THROUGH EARLY AFTERNOON FROM PORTIONS OF NRN IL/SERN WI EWD TOWARDS SWRN LWR MI. …BUT CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED FOR A POSSIBLE WW THIS AFTERNOON.”  Areas south and east of Kent County will have a slightly higher threat of severe weather between the hours of 4 PM and 10 PM.  Here’s the latest satellite loop, showing the breaks in the clouds and a surface weather map.  More sunshine will mean we get warmer and the warmer we get during the mid-afternoon, the better the chance for any severe weather.

    Storm is almost here in Muskegon very dark toward the lake looks like a small shelf coming in.

  2. Cort S. (Plymouth, NH) says:

    I see a confluence axis running from Big Rapids to Hudsonville to South Haven on the satellite image. It’s trying to pop up some showers along that axis, which will move to the NE at 50 mph. If only we had more instability…

    1. Stephen says:

      What about the popcorn farts starting in Illinois?

      1. kentwoodchicken says:

        Perhaps they need Tums!

      2. Cort S. (Plymouth, NH) says:

        That’s another confluence axis. That’s the trigger I was hoping for later this evening.

    2. Tom in Alger Heights says:

      Cort…got a link to what you’re looking at?

      1. Cort S. (Plymouth, NH) says:

        Mesoanalysis: http://climate.cod.edu/flanis/2km.php?loop=2&type=vis&region=MI

        Winds from the south in Benton Harbor and Kzoo, and southwest in Holland.

        1. Tom in Alger Heights says:

          Cool…thx

  3. Deb (Ludington) says:

    I am not an expert but whats a shelf???

    1. Cort S. (Plymouth, NH) says:

      A shelf cloud: http://www.srh.noaa.gov/jetstream/synoptic/shelf.htm

      A cloud that looks like a shelf, on the leading edge of a line of thunderstorms.

    2. INDY says:

      Deb T-TIME is over u I hope u got ready!!!! shelf clouds stack’ed clouds from the storm that is miles away!! INDYY

  4. Tom in Alger Heights says:

    Steady sun near the corner of Broadmoor and 44th. Can feel the temps going up and a steady SW wind. No thermometer at the office.

  5. kentwoodchicken says:

    I had confluence axis once- antibiotics cleared it up tho’.

    1. Stephen says:

      HAHAHAHA nice!

      1. kentwoodchicken says:

        I’ll be here all week! be sure to tip your server! BWWAAK!

    2. Tom in Alger Heights says:

      Ummm…yuck???

      1. kentwoodchicken says:

      2. Yup (Grandville) says:

        Don’t worry, Tom lacks a sense of humor.

      1. Stephen says:

        Dime to quarter sized hail Cort! That was amazing. From no precip to pouring rain then hail!

        1. Cort S. (Plymouth, NH) says:

          Take pictures! Place dimes, pennies, nickels, quarters (whatever you have) in the picture for reference!

          Make sure you’ve measured the size of the hail correctly. (A dime is 0.7 inch, a penny is 0.75 inch, a nickel is 0.88 inch, and a quarter is 1 inch.) Submit a report to the NWS: http://www.crh.noaa.gov/grr/spotter/

        2. Stephen says:

          Brang a few pieces inside. measured .8 for the biggest piece.

  11. Nicole in kentwood says:

    Kind of getting bummed. Was at least hoping for a thunderstorm.

  12. INDY says:

    Nice line on the roll in nothern ILL. we have to track that one!!! INDYY

  13. Stephen says:

    Had a few pieces of quarter sized hail!!

    1. Travis (Oxford, MI) says:

      Must not be too bad. No watch/warnings with that line.

      1. Stephen says:

        Wasnt bad was pouring rain then about 2 minutes of pea to dime sized hail then a quick burst of some quarter sized pieces. I’m happy now if it doesn’t storm anymore ill be ok since i got mine :)

  14. Nan says:

    The sun is coming out here in Kalamazoo. Wondering how much de-stabilization that will provide.

  15. dano (Norton Shores) says:

    Thunder lightning and heavy rain..

  16. Graham Wellington says:

    Any chance this thing escalates into a Killstorm?

    1. Stephen says:

      a what?

      1. Graham Wellington says:

        Thanks Cort, the weather amateurs on this board have a lot to learn from us professionals.

      2. Stephen says:

        ahhh i HATE the simpsons.

    2. DF (SE Mich) says:

      LOL!

  17. Marshall (Eaton Rapids) says:

    The sun is coming out in between cloud cover here, warming up little by little.

  18. Aaron says:

    I work in Grand Haven. Strange cloud just went over head, it looked like a barrel rolling down a hill. Never saw horizontal rotation like that, looked pretty cool.

    1. Matt(Grand Haven) says:

      Yeah, very fast moving scud clouds. Moving in all different directions!

    2. Kate (44th and Breton) says:

      someone posted pics of that to wzzms facebook wall, some lowering in the clouds

    3. Cort S. (Plymouth, NH) says:

      Roll cloud?

      http://www.youtube.com/watch?v=HEZCM1rIqaA

      It’s like a shelf cloud but it’s disconnected from the thunderstorm.

      1. Aaron says:

        It was rolling for sure. That is all about I can be sure of. Was a fairly large cloud. My coworker and I have never seen anything rotate like that. Really cool to see, should have taken a video.

        1. Matt(Grand Haven) says:

          Yeah, I was watching a broken area and it had several small areas of pretty intense rotation!

  19. Stephen says:

    Looking at the line in Illinois / So Wisc starting to organize.

  20. bnoppe(Albion) says:

    are those small pop up storms in IL the focal point for storm devlopment later

    1. Stephen says:

      making a line seems like.

  21. thundercat says:

    In Muskegon by Orchard View Schools never got any hail here. Saw the line coming in couple flashes of lightning a 5 minute down pour then done. Nothing exciting…..sigh

  22. bnoppe(Albion) says:

    64 and sunny in ALbion clouds are blocking the sun about 40% of the time

  23. fixxxerswrist says:

    i am aching i know this means storms are a brewin, would be nice to see some 80s and 90s though this march is still not very warm i see 50s next week, not 70s, i need exercise but master just sits at the computer all day gains weight doesn ot look for work

  24. Deb (Ludington) says:

    So are there going to be anymore storms this afternoon severe???

    1. Cort S. (Plymouth, NH) says:

      Probably not for you. This part of Michigan in the Red has the best chances: http://www.spc.noaa.gov/products/outlook/day1probotlk_1630_wind.gif

  25. 1/2″ hail reported in Muskegon county!

  26. jtwolters says:

    What’s the chance of them issuing a Tornado Watch for Ottawa County? We have plans tonight that probably will be canceled if there is a Tornado Watch.

    1. Stephen says:

      Looks like line segments i really don’t see any watches being issued.

      1. jtwolters says:

        Excellent. While I would absolutely love some good storms and exciting weather, it doesn’t work in tonight’s schedule for me! ha ha! :)

      2. kalamazooguy says:

        With the clearing and everything going on according to meteorology friends in Northern Illinois. A watch will probably be issued later for our area…might not be a Tornado Watch though.

  27. Stephen says:

    The lakes starting to fart now! Popcorn farts are starting up.

  28. Jeff (SE Ionia County) says:

    Feelin like the dew points are up today !

  29. Cort S. (Plymouth, NH) says:

    There’s a hail core that was overhanging M-37 just south of White Cloud. Now it’s dumping out just Southeast of White Cloud. Possibly greater than half inch.

  30. M in Montcalm says:

    Checking in at 63 degrees and sunny. Someone said if it gets to 66 then more chance for severe, right? Catch ya’ll later!

  31. Harry (Battle Creek) says:

    The Southern most end of that line of storms in Newaygo county is becoming more surface based.

  32. Cort S. (Plymouth, NH) says:

    Looks like we’ve reached Convective Temperature… showers starting to pop from GR and over Lake Michigan to Chicago. Just need some more instability and a stronger, more focused trigger.

    1. Swatz_Zoo(Cedar Springs) says:

      63 at the YARDofDUCKS playing in their pool with the sun popping in/out of the clouds, I have 3 more degrees to go yet will I make it? Will I see any storms? Only time and Mother Nature can tell me that. I wonder if Charles is getting any footage or decent chases yet? Haven’t taken the camera out yet, just sitting and waiting and wondering.

      1. Cort S. (Plymouth, NH) says:

        He’s probably taking lots of good cloud time lapse.

  33. INDY says:

    Nice cells popping over the lk …INDYY

  34. fixxxer says:

    Showers in wyoming. Still not feeling it for kent. Hardly no sun today here.

  35. Stephen says:

    SPC Update in a minute or 2

    1. INDY says:

      Watch coming!! INDYY

  36. Kate (44th and Breton) says:

    Storms near Newaygo now severe

  37. Stephen says:

    Outlook stayed the same. Muskegon to the east and southward.

  38. Montcalm County – Wow – I am surprised – I really thought severe would be in the south end of the state!
    https://nwschat.weather.gov/vtec/#2012-O-NEW-KGRR-SV-W-0001

    1. Swatz_Zoo(Cedar Springs) says:

      LOL, just as I figured and as usual just on the edge of that storm and will miss it unless it intensifies.

  39. Swatz_Zoo(Cedar Springs) says:

    I’m about 1/2hr East of Newaygo, hmmmm, the sun isn’t shining now and seems a bit darker. Haven’t checked radar yet though. I don’t know if my area will have enough surface temp to keep a thunderstorm sustained, still at 63

  40. INDY says:

    Storms are popping in Kent county INDYY

      No wonder Charles moved to Greenville, they get all the storms, I’m 15min West of Greenville straight shot and Cedar isn’t even listened on the areas impacted, oh why am I NOT surprised!! Temp just went down so my chance of storms are pretty slim now I think. 62.6

  42. INDY says:

    Sunshine temp 67* out at the YARDofBRICKS !!!! The sun is popping storms like crazzy check it out!! INDYY

    1. Swatz_Zoo(Cedar Springs) says:

      I can’t load the radar or NWS. LOL, to funny my son who went to Skywarn with me opened the window and screen and his body is 1/2 in 1/2 out looking to th sky, he said he heard little rumbles. My true weather spotter! LOL!

  43. Cort S. (Plymouth, NH) says:

    Slight risk of severe weather still exists across all of central and southern Lower Michigan.

    http://www.spc.noaa.gov/products/outlook/day1otlk.html

    Here’s the stuff that really matters, from the SPC. Worth a read:

    …MIDWEST/GREAT LAKES AREA THROUGH TONIGHT…
    CORRIDOR OF STRONGER SURFACE HEATING HAS RESULTED IN 19Z
    TEMPERATURES HAVING REACHED THE MIDDLE 60S TO LOWER 70S FROM SWRN
    LOWER MI SWWD. INITIAL LOBE OF FORCED ASCENT AND SMALL MCS OVER
    W-CNTRL LOWER MI SHOULD PROPAGATE E/ENEWD ON THE FRINGE OF THE
    GREATER HEATING. MORNING CONVECTION-ALLOWING AND OPERATIONAL MODEL
    GUIDANCE CONTINUE TO SUPPORT THE SCENARIO FOR CONVECTION
    BACKBUILDING SWWD AS WEAK COLD FRONT SWEEPS ACROSS THE WARM SECTOR.
    IT APPEARS PROBABLE A SW/NE-ORIENTED BAND OF TSTMS WOULD FORM BY
    EARLY EVENING FROM SRN LOWER MI INTO NRN IND. DEEP-LAYER FLOW WOULD
    BE NEARLY PARALLEL TO THIS TYPE OF ORIENTATION AND MAY MITIGATE A
    MORE ROBUST DAMAGING WIND THREAT. STILL…DID EXPAND SLIGHT RISK
    SLIGHTLY SEWD WITH POTENTIAL FOR AN ORGANIZED /BUT WEAKENING/ LINE
    PROGRESSING INTO NRN OH/LK ERIE VICINITY TONIGHT.

  44. INDY says:

    Not bad for March 12th just get ready for April and May Tornado’s for sure!! INDYY

    1. INDY says:

      And mid 80′s!!!! INDYY

  45. Deb (Ludington) says:

    Looks like a new MD or is it just me but they say watch is possible from Ottowa to Newaygo to Big Rapids east

    1. INDY says:

      Tornado Watch…..DDDD DDDDD DDDD!! INDYY

      1. Bruno (Northview H.S.) says:

        But “Pea Brain” said we wouldn’t get anything! Ha-ha-ha :)

        1. INDY says:

          Under the covers he’s rolls with a finger in his nose!! INDYY!

    2. Stephen says:

      No new MD

  46. weather watcher Oceana/Newaygo says:

    That was an intense yet brief storm that rolled through. I was in Hesperia when it came through and the rain was coming down in waves as the wind was whipping it along. If the strength of this storm is any indication of what the storms could be like later..to the south of me. Hang on to your hats.

    It wasn’t really warm and the cloud cover was abundant. The storm had little to build from. Yet it left quite a punch.

  47. INDY says:

    Like I said this morning 11am sun 4pm BIG storms yaaaaaa !!!! RIGHT ONNNN!! WARNINGS ARE OUT!!! INDYY

    1. Bruno (Northview H.S.) says:

      Good Job Indy!! You were right on!!

  48. Deb (Ludington) says:

    Just heard a report of a tree on the power line in Big Rapids they sure got it worse than me
