A slow moving storm system is moving east to allow part of eastern Iowa to see sunshine. If you draw a line from Decorah to Cedar Rapids, the area east of that line is cloudy and area west of it is sunny. The clouds will clear all of eastern Iowa this evening.

Updated Snow Forecast as of 9:30 PM

The heaviest of band of snow has been across southern Minnesota and crossing the state line into Iowa this evening. Snow reports have ranged from 1-4″…. the heaviest in Minnesota. The most unstable part of the atmosphere is across southern MN where the snow is falling at 1″ per hour. The forecast is for it to come south a bit overnight. The snow extends back into South Dakota.

Mar 4 MW Radar

The southern edge of the heavier snow will come close again to Waterloo and Dubuque (along Highway 20). There is a lot of uncertainty about how much snow makes it as far south as roughly Highway 20. I will keep the narrow band of 1-3″ on the southern edge of heavier band circled above. Here is the latest WSI RPM snow forecast.

Mar 4 RPM

Here is the graphic I will show during the 10 pm news (see below). ¬†There is going to be such a sharp cutoff. I could possibly narrow the 1-3″ snow band a bit more. I am going to leave it this way for the show.¬†Mar 4 Updated Snow Forecast

 

We will see how this plays out. I will post snow totals here on the blog tomorrow morning.

10PM Weather Updated

If you live along and north of Highway 20, you might have a brief light rain shower. Once it passes the sky will become clear. The radar below shows how small of an area it covers.

Update Sunday at 7:30 PM

There is a warm front at 850 mb and is trying to produce some snow, but as of this point I have only had one report of a few flurries along the IA/MN state line. The 850 mb warm front is going to be the culprit for any sleet or possible freezing rain south of I-80 as the precipitation begins to fall later tonight.

Feb 16 Warm Front

 

The evening sounding from Davenport shows a lot of dry air in place over eastern Iowa. This has been taken into account with the current forecast. The atmosphere will become saturated between now and midnight.
