SATURDAY NIGHT SPECIAL...

March 12, 2017

 

Most of the new 0z models are in (except for the EURO) and there is not much to nit-pick or be conflicted about. The track remains closely clustered among the various solutions leading to high confidence that much of my area along and north of I-80 will see 4-8" of snow starting Sunday night and ending later Monday. 2-4" will occur further south. The suggested track takes the surface low from Sioux City, Iowa to Ottumwa to Ft. Madison and on to Springfield, Illinois.

Northeast of the track by 100-150 miles will lay a moderate to heavy band of snow that should range from 4 to 8". Winter storm watches continue in my local area near and north of I-80. At some point Sunday these will be upgraded to winter storm warnings or winter weather advisories.

The winter storm is just now entering the Pacific Northwest getting set to dig into the Midwest the next 24 hours. Snow will break out in my local area towards evening Sunday and will continue through early afternoon Monday before tapering to flurries.

Here's the latest snowfall forecasts as of 11:00pm. First the GFS.

Now the NAM:

Finally the NAM 4k hi-res.

Here's the latest odds of at least 1" of snow from the Weather Prediction Center.

Sunday the models get down to business as the storm enters the Midwest. Hopefully no last minute shifts as the fine tuning gets serious. I'll have the latest so be sure and check back as we enter the down and dirty phase of the run-up forecast. Roll weather....TS
