...Every Now and
Again, We Have a Week that is Normal...
The
weather week opened on 7 May with a front approaching Louisiana from the
northwest, with a remnant front offshore.
The approaching front produced some severe weather in Louisiana, mostly
in northern Parishes. Hail was reported
in East Feliciana Parish, and damaging winds in Bienville, East Carroll, East
Feliciana, St. Tammany, Webster, and West Carroll Parishes. The front moved across Louisiana on the 8th. It produced rainfall, but without causing
additional severe weather. High pressure moved in to the region on 9-10 May,
but despite the mostly fair weather, double water spouts were produced off of
Grand Isle, which moved inland causing damage.
On 11 May, cyclogenesis took place off of the
Louisiana-Texas coast. This storm then
tracked across south Louisiana on 12th, causing isolated areas of
heavy rainfall, and thunderstorms nearly statewide. Fair weather moved into the region on the 13th.
For the week, Statewide precipitation averaged 1.2 inches, which was normal. However, rains were more abundant in southern
Parishes, and somewhat below normal in the northern half of the State (see
rainfall map below). Statewide
temperature averaged 73°F, which was also normal.
