UPDATE: A severe thunderstorm WARNING has been issued until 12:30 pm for portions of Acadiana, including Calcasieu, Jefferson Davis, Allen, Beauregard. Damaging winds and/or hail are possible in the warned area. Seek shelter immediately if you are in the path of this storm.
As promised, rain chances will be increasing today as a series of low pressure areas will move across the region. The first will slide through during the afternoon, dragging a weak front through, allowing rain to develop. Upper level support will accompany this front, so some rains could be heavy by this afternon.
Tonight, the front will settle over the Gulf waters, allowing some slightly cooler air to move in. Saturday will will be mostly cloudy, with more scattered variety showers and storms with highs in the 60s.
A surface low will develop over the southern Texas coast by Saturday night and start riding toward the northeast. The GRAF model pulls the low south of Louisiana, keeping the heaviest of the rain offshore, while the EURO model puts the low onto the Louisiana coast bringing heavier rains into Acadiana and southeast Louisiana. It will get windy and temperatures will drop during the afternoon Sunday as rains diminish.
If the low tracks the way the GRAF says, we'll see 2-3 inches of rain over most of Acadiana.
If the EURO solution verifies, we could see more than 4 inches in many areas between now and Sunday afternoon.
After the system pushes away, it will wrap around very cold air. Next week looks to be the coldest weather we've seen since last winter. Highs will struggle into the low 50s for highs, with 30s for lows early next week.
