Sciascia Posted March 11, 2014 Report Share Posted March 11, 2014 Skilling showed his updated RPM model that kicked out a band of 7-8" of snow right across N IL. IMO, I think N IL will be under a WSW tonight. High rez models are picking up better with this type of situation.I'd say they'd play it safe with an advisory. Global models still aren't buying into NW ideas. Quote ...The Artist Formerly Known as RJSnowLover... Link to comment Share on other sites More sharing options...
Money Posted March 11, 2014 Report Share Posted March 11, 2014 As of 0z, there's a 1000.8 MB L just south of Wright, WY....Actually, it's 999.8 in W. SD. Quote Link to comment Share on other sites More sharing options...
Geos Posted March 11, 2014 Report Share Posted March 11, 2014 Current grid forecast has 1-3". Rain or rain/snow mix until 10pm before it starts snowing. Then ends everything about 6am.

Trinomial Posted March 11, 2014 Report Share Posted March 11, 2014 I can see the grid changing if the gfs moves towards the nam in the 00z runs. I feel like the nam has a decent track record with these types of storms. Quote Link to comment Share on other sites More sharing options...

Money Posted March 11, 2014 Report Share Posted March 11, 2014 NAM has started. I'm guessing a similar solution as 18z, maybe a hair south, but nothing drastic. All the high-res models are showing a stronger/nw solution. Dont think it changes. Quote Link to comment Share on other sites More sharing options...
Tom Posted March 11, 2014 Author Report Share Posted March 11, 2014 Another reason why I buy a northern solution is bc this storm during both cycle 1 & 2 cut through N IL and a NAM solution may be the way to go. This time there isn't much of a severe wx threat due to the cut-off LP near the Gulf of Mexico that is taking away that energy that would otherwise blossom out ahead of this system. During this 3rd cycle, the PV to the north is keeping the storm from cutting up through N IL this time around and the saving grace from a rain system. I think NAM keeps the strength for 00z runs and track is similar to 18z. It may come in even juicier as well. Quote Link to comment Share on other sites More sharing options...
Scott26 Posted March 11, 2014 Report Share Posted March 11, 2014 I'm going to attempt to extrapolate the NAM at 4 hours lol. Looks like the low is in the same position in Nebraska as 18Z maybe even a tick north. My guess this run is going to be about the same, but we will see. 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted March 11, 2014 Author Report Share Posted March 11, 2014 I told ya guys, high rez is the way to go with these dynamic systems. I'm afraid this may cut too far NW and give us mixing issues up this way if it blows up earlier. On the other hand, PV up north is strong enough to keep it south for N IL to be in the corridor of heavy snow. Quote Link to comment Share on other sites More sharing options...

But, unfortunately, this is probably the NAM just being the NAM with QPF.. Quote Link to comment Share on other sites More sharing options...
