This NOAA satellite image taken April 6, 2011 at 10:45 AM EDT shows variable cloud cover from the Great Lakes and the Ohio Valley through the Central Plains and into the Four Corners as a long frontal boundary extends through the regions. On the western end of this front, light rain and high elevation snow showers develop in parts of the Great Basin. On the eastern end of this front, a wave of low pressure triggers rain and light snow showers from areas of southern Michigan and northern Ohio through Pennsylvania and New York. Meanwhile, low pressure to the north keeps breezy conditions over the Northeast. To the south, high pressure over the south Atlantic coast provides dry and calm weather activity from Texas through the Southeast. Low relative humidity values, warm temperatures, and gusty southerly/southwesterly winds lead to an increased risk of fire weather activity from southeastern Arizona through much of northern Texas, the Ozarks, eastern Alabama and southwestern Georgia. less
