It was a windy, warm day with wind gusts from the south-southwest as high as 40 mph & temperatures as high as 61 degrees.
Scattered showers & couple isolated t’storms are developing. These are occurring along & just ahead of a surface cold front. It does not look like it will get a lot colder behind the front.
The data tonight is definitely warmer for Wednesday & Thursday with highs in the 50s with much less wind & lots of sunshine.
There are two storm systems dropping in the Northwest. One is in British Columbia/Alberta & the other is off the coast of California, so I am not going to call it an Alberta Clipper any longer. Both pieces will combine & eventually, a new surface low will be spawned east of Denver. This will tend to move east-southeastward like a clipper, but have abundant moisture, behaving more like a traditional Colorado low.
This has the potential to bring a significant snow event of 8-14″ of snow from eastern Colorado to Nebraska with perhaps 4-8″ of snow in Iowa. We will be on the edge of a snow band on the northern fringe of the precipitation associated with the system. Right now, a band of 3-5″ may still reside Davenport, Iowa to Kankakee, Illinois to Plymouth, Indiana. The viewing area may see 0.4″ in our south to around 3″ in our far north.
Another note is that part of the precipitation will be rain in the southern half of the viewing area.
Timing is still generally Friday night-Saturday.
It looks quite windy with the system with gusts of 35 mph to perhaps 40 mph, but the snow looks quite wet & slushy.
