SATURDAY UPDATE ON NEXT WEEKS SNOW SYSTEM:
The theme I've been promoting the past few days is that next weeks winter storm is becoming better organized with each passing day. The system is digging and phasing and that's what you look for in a deepening storm. In fact, today's data has a closed circulation at both 850 and 500mb. Here's what the system looks like at jet stream level 500mb. The circulation center is near Des Moines Tuesday evening.
The 850 circulation about a mile up is passing through NE Iowa. The rule of thumb is the heavy snow falls NW of the 850 low where temperatures are cold enough to support it. That eliminates all of my area for any accumulating snow. See the center below passing just west of Decorah, Iowa.
With that path the heavy snow band continues to shift NW and its becoming clear that the NW third of Iowa, southern Minnesota and NW Wisconsin will do the shoveling and plowing Tuesday and Tuesday night. Below you can see the EURO snowfall forecast.
The GFS is likely too far SE with its accumulations into parts of EC Iowa and southern Wisconsin.
With the surface low heading over eastern Iowa Tuesday that will thrust enough warm air into my area for rain instead of snow.
This is a much warmer scenario than having the low pass south and some places in far SE Iowa and WC Illinois may give 60 a run Tuesday afternoon. Widespread 50s can be expected near and south of I-80. There might even be a few thunderstorms in that part of my area.
Finally winds switch to the NW Wednesday and much colder air surges in behind the storm. Holiday travelers can expect tough conditions in Minnesota and NW Wisconsin early Wednesday but conditions will improve by afternoon as the snow ends up that way. A new trend on the EURO is some light snow that could drift into my area later on Thanksgiving day. At this point little if any accumulation is expected. Thus. little if any travel issues. More on that in later forecasts. I just wanted to get it out there that my area will be spared the snow from the more significant event Tuesday. Roll weather...
