Can You Find the Cold & Warm Fronts?

March 26, 2012: Fronts and Temperatures.
The two maps to the left show the frontal systems yesterday afternoon across the lower 48 states along with the high temperatures for the day. It is a perfect example of frontal systems and the associated air masses (and temperatures) on either side of the fronts. Note the area of red color with temperatures into the 80's F ahead of the cold front extending from western Nebraska down to New Mexico. This area of red with 80 F temperatures also stretches across the southeastern U.S. and is south of an advancing cold front. What a dramatic temperature difference on the other side of this frontal system with high temperatures only in the 30's F and 40's F and 50's F across the upper Midwest, Great Lakes and New England Region. High temperatures in the Pacific Northwest were also much cooler and are generally in the 40's and 50's F.

NOAA: Winter 2011-12 Much Warmer than Normal
On average, the 2011-2012 winter was a mild one for the contiguous United States. When NOAA’s National Climatic Data Center crunched the numbers for December, January and February—”meteorological” winter for 2011-2012—it stacked up as the fourth warmest of the past 117 winters. The seasonal average temperature was 36.8 degrees Fahrenheit, which is 3.9 degrees above the 20th century average.

Records "Look-Up" Maps

Look Up Records and Map Them.

What a great site for anyone interested in looking up record temperatures, precipitation amounts and snowfall amounts. This program at NCDC allows you to choose the time frame, the variable, and the location and the records are then mapped for you.

The map to the left shows the record high temperatures on March 12, 2012 produced at this site. Be patient when accessing the site, it loads slowly.
