Record-breaking warm weather advances beginning of growing season
Figure 1. Projected weather conditions at approximately 5,000 feet above sea level, 8 p.m. on Monday March 19, 2012. Color contours depict temperature (°C) while winds are expressed in arrow/vector form on grid points in white (direction of arrow indicates direction, length of arrow depicts velocity). Solid white lines depict general pressure pattern and air flow.
Figure 2. Observed (solid colored lines), normal (solid black line) and projected (dashed line) base 50°F growing degree accumulations for 10 warmest Marches on record at Benton Harbor, Mich. Projections for the 2012 data include latest short- and medium-range National Weather Service forecast guidance through March 31. Growing degree days are calculated with the Baskerville-Emin methodology.

Remarkable week-long March heat wave hitting U.S.
Figure 1. Is this March or June? Predicted high temperatures for Wednesday, March 14, 2012 over much of the Midwest are more typical of June than March.
Figure 2. New daily high temperature records were set at 208 locations yesterday, according to our new Extremes web page, with data from NOAA's National Climatic Data Center.

A highly unusual week-long heat wave is building over much of the U.S., and promises to bring the warmest temperatures ever seen so early in year to a large portion of the Midwest. The exceptional heat will also be exceptionally long-lasting: record-breaking temperatures 20 - 30 degrees F above normal are expected today through next Wednesday for much of the Midwest and Northeast U.S. The weather system responsible is a large upper-level ridge of high pressure that is "stuck" in place--a phenomenon known as a "blocking pattern." The jet stream is bending far to the south over the Western U.S., then bending far to the north over the Rockies and into Canada, and lies far to the north of the eastern U.S. Since the jet stream acts as the boundary between cold air to the north and warm air to the south, the current looping pattern is bringing colder than normal temperatures and snow to the mountains of the West, and summer-like warmth to the Eastern U.S. It is common for the jet stream to get stuck in a blocking pattern for a period of a week or more, but not in to this extremity. If the current model forecasts prove correct, a high pressure ridge over the U.S. bringing heat this intense and long-lasting in March will be unprecedented in the historical record, going back to 1872.
