...Cool and Wet Week in Louisiana...

The weather week opened on 1 February with high pressure that persisted through the 3rd. Despite the high pressure, no freeze was occurred in the State. On the 4^th, cyclogenesis occurred in the western Gulf of Mexico, and the storm system tracked over Louisiana bringing widespread rains. Rain totals were light in northern Parishes and quite heavy across most of southern Louisiana. Totals of 3-4 inches were commonplace. This weather pattern was common in December 2009, and indicative of El Nino winters in the region. Conditions began to clear on the 5^th, as high pressure moved back in to the area. This pattern persisted from 5-7 February, though again, no freezing temperatures occurred.

For the week, Statewide precipitation averaged 2.4 inches, which was 1.2 inches above normal. Louisiana's temperature averaged 46°F, which was 5°F below normal.
