reber500 Posted May 3, 2012 Share Posted May 3, 2012 I'm surprised that the Storm near Oak with the Hook hasn't rapped up/ cycled yet.. Link to comment Share on other sites More sharing options...
andyhb Posted May 3, 2012 Share Posted May 3, 2012 I'm surprised that the Storm near Oak with the Hook hasn't rapped up/ cycled yet.. The storm that formed on its flanking line is currently interfering with its inflow. This was pretty impressive a few minutes ago... Link to comment Share on other sites More sharing options...
Buckeye05 Posted May 3, 2012 Share Posted May 3, 2012 I'm surprised that the Storm near Oak with the Hook hasn't rapped up/ cycled yet.. Well the rotation is weakening now because of the merge. Wait a bit for it to get it's act back together. Link to comment Share on other sites More sharing options...
reber500 Posted May 3, 2012 Share Posted May 3, 2012 Storm that was near Oak isn't even showing decent rotation on SRM.. But it does have some weak rotation on Base.. Link to comment Share on other sites More sharing options...
SouthernNJ Posted May 3, 2012 Share Posted May 3, 2012 The second storm behind the first one has taken the energy away and is forming its own decent meso. Link to comment Share on other sites More sharing options...
reber500 Posted May 3, 2012 Share Posted May 3, 2012 It looks like the Storms North of Superior it's becoming one of those situations where there is two Supercells all congealed into the same storm, just with two separate areas of rotation/ two hooks...

reber500 Posted May 3, 2012 Share Posted May 3, 2012 What a beast in Southern ND right now... Noticed that a few minutes ago.. Looks like a Monster...

SouthernNJ Posted May 3, 2012 Share Posted May 3, 2012 Sizeable funnel cloud close to Davenport NE. The circulation more than supports this spotter report. Link to comment Share on other sites More sharing options...
reber500 Posted May 3, 2012 Share Posted May 3, 2012 Wow... That Storm near Davenport has got it's act together quick, pretty classic supercell, with pretty good rotation.. ALTHOUGH the Rain cooled air looks like it may out run the storm thus getting rid of the Tornado threat, unless it cycles.. Link to comment Share on other sites More sharing options...

MNstorms Posted May 3, 2012 Share Posted May 3, 2012 MESOSCALE DISCUSSION 0670 NWS STORM PREDICTION CENTER NORMAN OK 1106 PM CDT WED MAY 02 2012 AREAS AFFECTED...PARTS OF CENTRAL MN AND NERN SD CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE VALID 030406Z - 030430Z PROBABILITY OF WATCH ISSUANCE...60 PERCENT SUMMARY...WW WILL BE COORDINATED FOR POTENTIAL ISSUANCE ACROSS PARTS OF CENTRAL MN INTO NERN SD. DISCUSSION...AT 04Z...A SURFACE FRONT EXTENDED FROM NERN SD ESEWD THROUGH CENTRAL MN TO THE TWIN CITIES METRO INTO CENTRAL WI. A MODERATELY UNSTABLE AIR MASS RESIDING ALONG AND S OF THIS BOUNDARY WITH A FEED OF LOW LEVEL MOISTURE EXTENDING NWD ACROSS SERN SD/SWRN MN APPEARS TO BE SUPPORTING THE ONGOING STRONG TO SEVERE STORMS OVER WEST CENTRAL MN AND NERN SD. THE NRN CHIPPEWA STORM IS LIKELY LOCATED ON OR VERY CLOSE TO THE WNW-ESE ORIENTED BOUNDARY...AND THUS MAY BE SURFACE BASED. WATER VAPOR IMAGERY AND OBJECTIVE ANALYSES SUGGESTED A FEW PERTURBATIONS/JET MAXES MOVING THROUGH THE ERN DAKOTAS TO CENTRAL MN WHICH SHOULD SUSTAIN THE ONGOING ACTIVITY AND SUPPORT NEW TSTM DEVELOPMENT. EFFECTIVE BULK SHEAR OF UP TO 50 KT WILL MAINTAIN THE LIKELIHOOD FOR ROTATING UPDRAFTS AND THE ATTENDANT THREAT FOR LARGE HAIL AND DAMAGING WINDS.

OceanStWx Posted May 3, 2012 Share Posted May 3, 2012 I had to miss out yesterday being on the forecast desk and having spotter training last evening, but I did want to post something I noticed during the morning. The visible satellite from around 10 AM yesterday morning. You can clearly see the arcing OFB from the morning convection, but there was also a secondary boundary that made itself present as daytime heating commenced (running SW to NE). Looking at surface obs, this roughly marked the boundary of richer surface moisture. Mid to upper 60s dewpoints resided south of the boundary, and low 60s to upper 50s to north. The boundary actually made very slow progress north during the day, about 30 miles in total. Sure enough it was along this boundary that the reported tornado occurred, despite being south of or on the southern edge of the moderate risk.

Interesting......a new outflow boundary looks to be setting up on the Iowa/MN border from todays convection. Really visible on the loop. Link to comment Share on other sites More sharing options...
MNstorms Posted May 3, 2012 Share Posted May 3, 2012 Interesting......a new outflow boundary looks to be setting up on the Iowa/MN border from todays convection. Really visible on the loop.
