Monthly precipitation totals over most of the Arctic Basin average about 15 mm (0.59 in) from November through May, and rise to 20 to 30 mm (0.79 to 1.18 in) in July, August, and September. [6] The dry winters result from the low frequency of cyclones in the region during that time, and the region's distance from warm open water that could ...
Over the contiguous United States, total annual precipitation increased at an average rate of 6.1 percent per century since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent).

A winter storm will drop snow from Houston, Texas to New Orleans, Louisiana as an arctic air mass extends a historically cold January. Snow, sleet and freezing rain are set to fall across parts of ...
Rainfall in these regions averages between 300 and 600 millimeters (11.8 and 23.6 in) per year, with lower amounts across Baja California Norte. Average rainfall totals are between 600 and 1,000 millimeters (23.6 and 39.4 in) in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara.
Over 175 million people across the country are under some form of cold weather alert as the mid-Atlantic and Northeast ready for another round of rain and snow and southern states brace for frigid ...
Precipitation totals in mm While temperature is typically visualized using a line, some climographs opt to visualize the data using a bar. This method's advantage allows the climograph to display the average range in temperature (average minimum and average maximum temperatures) rather than a simple monthly average.
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather.
