Flood watch issued for rapid snow melt this week

We're about to witness a dramatic transformation across the Upper Midwest this week.

Minnesota looks like an icy alien world from space in NOAA's MODIS Terra 1,000-meter resolution visible image today. Deep snowpack enhances the outline of rivers and lakes across Minnesota.

Instant spring

We're about to feel a rapid warming trend this week. Southerly winds spike temperatures into the 40s as soon as Tuesday afternoon. The magnitude of warmth in our inbound air mass may push temperatures to the 50-degree mark across parts of Minnesota by Wednesday afternoon.

My read is that the temperature output below could be a few degrees too conservative by Wednesday.

Spring is not far away. Highs in the 60s make it as far southeast Iowa Wednesday.

March Rain Ahead

The surge of warmth this week is courtesy of an inbound storm system pulling up warmer air from the Gulf of Mexico. The cold side of the storm will produce heavy snow in the eastern Dakotas and western Minnesota. Eastern Minnesota may pick up a couple snowy inches on the backside Thursday as colder air returns.

The Canadian model handled last weekend's storm system well. Here's the sequence of events Tuesday to Thursday this week via the Canadian model.
