A very warm pattern for the Heartland

Looking ahead, a slow-moving storm centered over the upper Midwest will drift eastward, reaching the northern Atlantic States by Thursday. Another widespread outbreak of severe thunderstorms can be expected later Tuesday, especially from Michigan to eastern Texas. On Wednesday, lingering strong thunderstorms may spread as far east as the upper Ohio Valley and the lower Great Lakes region. Additional rainfall associated with the storm could reach 1 to 3 inches, especially in the Mid-South, Northeast, and along the southern Atlantic Coast. Elsewhere, much cooler air will arrive in the Far West, but heat will build by week’s end on the High Plains.

The 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions in the Far West. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal weather across the nation’s northern tier from the Pacific Northwest to the Great Lakes region.

2012 was warmest, second most extreme year on record for the contiguous U.S.

2012 was a historic year for extreme weather that included drought, wildfires, hurricanes and storms; however, tornado activity was below average, according to an analysis released today by NOAA’s National Climatic Data Center. The average temperature for 2012 was 55.3°F, 3.2°F above the 20th century average, and 1.0°F above 1998, the previous warmest year.

NOAA: Risk for major Spring flooding is low this year

No area of the country faces a high risk of major to record spring flooding, largely due to the limited winter snowfall, according to NOAA’s annual Spring Outlook, which forecasts the potential for flooding from April to June.

A colder, snowier Winter ahead for the Badger State?

La Nina is returning, and will continue through this coming winter season.

For south-central and southeast Wisconsin, this may bring increased chances for below normal temperatures and above normal precipitation (and snowfall). However, the correlation between La Nina and winter temperatures and precipitation in south central and southeast Wisconsin is not as robust as it is with El Nino.

The latest long range temperature forecasts from the Climate Prediction Center suggest equal chances for above, near and below normal temperatures for south central and southeast Wisconsin for meteorological winter (December 2011, January and February 2012).

The latest long range precipitation forecast from the Climate Prediction Center suggest increased chances for above normal precipitation for southeast and parts of south central Wisconsin for meteorological winter, with equal chances for above, near and below normal precipitation elsewhere across the area.
