Atmospheric River to Begin to Impact the Northwest U.S.; Gusty Winds in the Northeast U.S.

A strong atmospheric river moving into northern California later Tuesday will bring a threat for moderate to heavy rainfall and flooding, gusty to high winds, and mountain snows for parts of the Northwest U.S. through at least Wednesday. Gusty winds and isolated rain and snow showers will continue in the Northeast U.S. Tuesday behind a cold front. Read More >

Rare is the snow pile that survived high temperatures climbing into the mid 60s on Monday! The power of that strengthening March sunshine, combined with light winds, can really push those temperatures above what is expected. There were few complaints about the unexpected warmth.

Below is a map showing those high temperatures from Monday across the Upper Midwest:

Temperatures for much of this week should average above normal. One hitch in the forecast will be later in the week, when winds turn onshore. These winds will result in areas near Lake Michigan remaining much cooler than inland areas Wednesday afternoon through Friday. Inland areas will likely rise into the lower to middle 50s, while lakeshore areas remain in the middle to upper 40s. The normal high temperatures for this week are mainly in the lower 40s.

Daytime temperatures today are expected to peak into the mid 60s once again!

Here's the Climate Prediction Center's outlook for temperatures over the next 2 weeks:

6-10 Day Outlook

8-14 Day Outlook

The best chance for showers will be tonight, as a cold front moves across southern Wisconsin. Slight chances for thunderstorms are also forecast tonight. Chances for showers will continue Wednesday into Thursday, as the front stalls to the southeast of the area. We may see some fog develop at times tonight into Wednesday as well, with winds weakening and moist air lingering over the area.
