St Paul Storm Posted December 15, 2021 Report Share Posted December 15, 2021 42F and dense fog right now here. Sounds of water rushing down the gutters as the snowpack gets obliterated. MPX talking possible gusts near 80mph with the storms later. There is an eerie calm this morning with no wind at all. Hard to fathom what’s about to take place in a few hours. I’m going to be clearing the drains in my yard and the street from ice and snow to make sure I don’t run into flooding issues. Fortunately with storm motion of 70mph excessive rainfall shouldn’t be too much of an issue. 2 Quote Link to comment Share on other sites More sharing options...
james1976 Posted December 15, 2021 Report Share Posted December 15, 2021 Agreed. Was about to comment on the eerie feeling. I'm at work with the doors and windows open. Feels like late spring. Already 57 and its muggy with a light breeze. A few clouds are floating by from the SW and they are moving quickly. 1 Quote Link to comment Share on other sites More sharing options...

St Paul Storm Posted December 15, 2021 Report Share Posted December 15, 2021 Special Weather Statement…YIKES!: Description ...TODAY'S VOLATILE DAY OF WEATHER HAS NOT BEEN SEEN BEFORE IN MID DECEMBER... An unprecedented outbreak of severe thunderstorms for this time of year is likely early this evening. The line of thunderstorms will race northeast across southern and eastern Minnesota into Wisconsin between 5 PM and 9 PM. Widespread wind damage from gusts possibly exceeding 80 mph will accompany the storms. Tornadoes are also possible. The highest risk of severe thunderstorms is southeast of a line from Redwood Falls to Rush City. Storms will be moving between 60 and 70 mph! Conditions will deteriorate very quickly. Unless preparations are made ahead of time, it may be hard to take adequate shelter when one notices storms beginning to approach. These are expected to be high end damaging wind producers, so pay close attention to warnings issued later today. 1 3 Quote Link to comment Share on other sites More sharing options...

Hawkeye Posted December 15, 2021 Report Share Posted December 15, 2021 It's like a warm spring morning. It's humid, everything is wet, and the air has that moist odor. The strongest wind will likely remain west of Cedar Rapids, but 60 mph is possible as the front passes through between 7-8pm.

Iowawx Posted December 15, 2021 Report Share Posted December 15, 2021 SPC now has CR in the enhanced risk. HRRR is suggesting gusts around 65mph. Could be stronger with the line of storms. 1 Quote Link to comment Share on other sites More sharing options...

OmahaSnowFan Posted December 15, 2021 Report Share Posted December 15, 2021 Verbiage from SPC update a bit ago. https://www.spc.noaa.gov/products/outlook/day1otlk.html?fbclid=IwAR0R8QHmQeszqTcsrDgJEKB1vJo1FK4xGl-mZduLaACqYZSpLBdYeQwRSLs Though the elevated mixed layer plume will act to cap the moistening boundary layer, strong forcing for ascent with the surging dryline and within the left-exit region of the intense mid-upper jet streak will quickly remove convective inhibition in a narrow zone along the dryline by mid afternoon (20-21z), when convective initiation is likely across east central/southeast NE and northeast KS. Extremely strong wind profiles will accompany the ejecting midlevel trough, with speeds approaching 125 kt at 500 mb and 70-80 kt not far above the ground. Effective bulk shear will also be quite strong at 70-80 kt. The strong linear forcing for ascent and cap will support a narrow line of storms, though the very strong deep-layer shear vectors/long hodographs oriented across the boundary, and increasing low-level buoyancy by mid-late afternoon, should allow some supercell structures within the band of storms. Downward momentum transport by the convection will result in the potential for widespread wind damage with peak gusts potentially in the 75-100 mph range, and embedded circulations will be capable of producing a few fast-moving tornadoes (one or two of which could be strong) with both right-moving supercells and embedded QLCS mesovortices. 2 Quote Link to comment Share on other sites More sharing options...

You can see the HRRR here at 9pm how one band has just moved through the CR corridor and another on it's heels. That's what it's been showing here as well. Strong winds right before the storms and of course during the storms, then a relative period of "calm" before the winds switch to the west and increase again. Last night gusts were showing 85 mph in the second batch. Quote Link to comment Share on other sites More sharing options...
OmahaSnowFan Posted December 15, 2021 Report Share Posted December 15, 2021 Given things getting pulled back a bit and Omaha being more in the crosshairs, I plan on heading out to the Missouri Valley/Onawa area along I-29 so I can be still be close enough to storms as they head through the metro area and head back home if there is any damage, etc. I plan on trying to stay with the storm until maybe shortly after dark also depending on storm speed, visibility, etc. After I leave those storms I might stay up in northwest Iowa to experience the secondary rush of extreme winds that were being forecast up to 85 mph last night. 5 Quote Link to comment Share on other sites More sharing options...

Heck the SPC didn't even have a marginal risk on it's first 3 day outlook. But the CAPE keeps increasing and most models all show 1000+. I'm getting more and more concerned with the Omaha area. The HRRR is slowing things down allowing storms to form and mature well west of here now and move into a very volatile environment. 1 3 Quote Link to comment Share on other sites More sharing options...
