While it can still be subject to last minute shifts like every other model, when it's consistent like this it's not often that it's wrong, from my experience. The 00z 3km NAM is actually not too far off from the 18z Euro now. I wouldn't be surprised to see other 00z runs settle somewhere around there too. The NAM showing the heaviest totals near your back yard and NW Iowa seems like a good bet to me. And the NAM has been really good as of late.

Tom Posted January 27, 2023 Report Share Posted January 27, 2023 06z RDPS...I remember the Canadian model was one of the best to use tracking clipper systems during the '13-'14 season among others. Some of the models are suggesting the lake get involved depending on the track of the wave, NE IL may score a few inches if things line up right. 1 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted January 27, 2023 Report Share Posted January 27, 2023 LOT has some interesting wording suggesting convection within the meso bands that will develop...they are also suggesting snow ratios to be 12:-14:1... There will be several sheared mid-level short-wave impulses interacting with a quasi-stationary frontal boundary draped across the area in a zone ranging between roughly I-80 on the north end of model guidance and US-24 on the south end of model guidance during the day on Saturday. The lower and mid-level wind response to these disturbances acting upon a tight baroclinic zone (thermal gradient) will help induce a frontogenetic circulation and likely a narrow (~2-4 county wide) snow band producing moderate to heavy snow. Finally, upper level jet dynamics are also expected to aid in the large scale ascent. A few additional pieces of the puzzle will be steep mid-level lapse rates within and above the DGZ plus a plume of 150-200% of normal PWATs to tap into. The reduced static stability and potential for even some upright convection is a common trait of mesoscale snow band events. Izzi touches on bit on the lake enhancement scenario... Finally, improving lake induced thermodynamics and convergence should help at least loosely organized lake enhancement take shape late Saturday night. Inversion heights are expected to be modest, but good convergence and lake induced CAPE (100-300 J/kg) could yield some additional minor accumulations near the lake in a zone from the Chicago shore and points south and into parts of northwest Indiana, depending on how quickly the convergence axis shifts. The lake effect snow threat should wind down by mid day Sunday. Temperatures will only recover to near/around 20 northwest and mid-upper 20s elsewhere Sunday afternoon, with slowly diminishing northerly winds keeping wind chills in the single digits and teens. 2 Quote Link to comment Share on other sites More sharing options...

westMJim Posted January 27, 2023 Report Share Posted January 27, 2023 The temperatures have fallen here in the last hour and looking out the window the wind has also picked up as well. At this time there is a little bit of red/pink to the sky looking to the west. That is a little odd as the sky to the east is clear but there are clouds to the west and they (the clouds) are red.

tStacsh Posted January 27, 2023 Report Share Posted January 27, 2023 Models are all over the place still. So I'm going with the globals at this point. Euro and GFS are very similar. Canadian is south. Nam is way too far north. 1 1 Quote Link to comment Share on other sites More sharing options...
CentralNebWeather Posted January 27, 2023 Report Share Posted January 27, 2023 I think the Canadian will be pretty close to what pans out in my area. It has stayed very steady with these amounts. Still believe in the Arctic air that a band or two could set up and drop higher amounts of snow over a small area, but those are nowcast and radar. 2 Quote Link to comment Share on other sites More sharing options...
