Rare July cold front to bring drier air.
July cold fronts in Acadiana are usually extremely rare, but the third one of July 2014 arrives Tuesday morning. A few showers are possible with the passing front, followed by lowering humidity levels for Tuesday afternoon. Wednesday will feature the driest air with dew points in the lower to middle 60s, as compared to the muggy middle 70s of Monday afternoon. We’ll see rain chances return for Thursday and Friday. Enjoy the break!
Another shot of cool air.
A third cold front in July for South Louisiana?!?! Yes, as hard as it may be to believe, another potent cold front will push southward across the eastern 2/3 of the country for the last week of the month. The front looks to pass Acadiana on Tuesday, dropping our dew point from the muggy 70s into the much more pleasant 60s by Wednesday morning. The break from the high summertime humidity may stick around for a few days, so there’s good news ahead!
Hurricane Arthur makes landfall.
The first Category 2 hurricane since Hurricane Ike in 2008 made landfall late Thursday evening near Cape Lookout, North Carolina. Hurricane Arthur came ashore with maximum sustained winds of 100 mph after strengthening steadily on Thursday. The Outer Banks will feel the brunt of the storm throughout the night before Arthur moves off to the northeast and eventually transitions to a non-tropical system due to the cooler waters of the North Atlantic.
Tropical Storm Arthur.
The first named storm of the 2014 Atlantic Hurricane Season is on the move. Tropical Storm Arthur had maximum sustained winds of 70 mph as of 10 PM CDT on July 2, moving to the north. A turn to the northeast is likely Thursday as the system becomes a hurricane. The Outer Banks of North Carolina may be significantly impacted early Friday morning, before Arthur moves to the northeast over the Atlantic.
US Tornadoes 2014
Tornadoes are possible across the country’s mid-section Tuesday evening along a distinct warm front. We are actually due to see more tornadoes this severe weather season as the total so far in 2014 is as low as it’s been at this point of the year since 2005. That may change over the next 24 hours, but so far, 2014 has been a below-normal severe weather year.
Doppler Radar Estimated Rainfall, May 28, 2014
Here’s a look at Doppler radar estimated rainfall totals from Wednesday morning. The bulls-eye area is from Jennings to Lafayette along I-10. At the airport in Lafayette, 6.86″ fell in just nine hours between 2:00 and 11:00 AM. This was all caused by an upper-level area of low pressure to our northwest helping tap deep moisture from the Gulf of Mexico. Below is an animation of the heavy rain event, which in some spots dropped about 10-15% of our average annual rainfall in under 12 hours!
Drought conditions developing across SW Louisiana, May 22, 2014.
The latest Drought Monitor was released on Thursday and it confirms what we know – drought conditions are developing across Southwest Louisiana. Moderate to severe drought covers areas from Lafayette westward. The rain deficits are substantial year-to-date. Lafayette is down 7.23″ for the year thru Thursday, while Lake Charles is down 9.33″ compared to normal. There is little hope for any rainfall until the middle of next week when some energy above may move into the state.

Tuesday’s low of 20° at Lafayette was the coldest reading in four years and as cold as we’ve been in almost 18 years! The last time the temperature dropped into the teens was on February 5, 1996, when we hit 16°. There are a lot of similarities between the winter of ’95-’96 and ’13-’14, including a long-wave ridge over the Northern Pacific and persistent troughing over North America. Early 1996 featured a low of 21° in January at Lafayette, an 18° and 16° low in February, and a late 25° low on March 9. If we use 1996 as a guide, more bitterly cold air may be in store for South Louisiana before this winter departs.
Data revealed at an American Geophysical Union scientific meeting in San Francisco Monday is record-breaking. NASA satellite data shows the temperature in East Antarctica in August 2010 hit -135.8° F. On July 31, 2013, the temperature there hit -135.3°. The world record had been -128.6°. That is cold!!! By the way, the record for heat was set way back on July 10, 1913, when a thermometer recorded 134° at Death Valley, CA.
