[PBARC] Severe Weather threat

[E Glenn Wolf Jr]

All,

The next in this series of severe storms arrives in the service area 
from the NW early tomorrow morning. WSI has set every network in the 
Entergy System to Yellow for Thursday (this is the first time I can 
remember every network activated for the same 12-hour time period). All 
areas have the potential for seeing severe weather. Please see the WSI 
Special Weather Statement and NWS images in the Details section.

Areas now forecasted to be most at risk appear to be EC and SE EAI, all 
of EMI, ETI (north of RT 190), and northern portion of ELL and the area 
of EGSLA and ELL (north of I-10 and I-12). As the front reaches the 
system these areas are subject to adjustment.

There is another system due on Saturday night-Sunday, but we will 
provide information on that system later. Please monitor the WSI 
Forecast/Alerts and the NWS Watches/Warnings for your local area.

Be Safe,

Bill

****THREAT FOR WIDESPREAD SEVERE STORMS ACROSS MUCH OF ENTERGY STARTING 
LATE TONIGHT THROUGH ALL OF THURSDAY.***
*
An area of low pressure will drop into the southern Plains and 
strengthen. The storm will then track across northern AR during the day 
Thursday with the associated cold front passing through the service 
area, as well. The storm and front exit MS and southeast LA Thursday 
evening.

*ARKANSAS:* A line of strong to severe storms will develop in eastern 
OK/northeast TX late tonight and move into western AR around sunrise 
Thursday. The line of storms will likely become more intense as it 
passes across the state during the morning and afternoon. The storms 
should leave eastern AR by late afternoon. The southern half of the 
state has a better chance of getting more severe storms than the 
northern half. Severe amounts of lightning, large hail, and wind gusts 
over 50 mph will be likely. Isolated tornados will also be possible, 
especially in southern and eastern AR.

*MISSISSIPPI:* The line of severe thunderstorms is expected to enter 
Mississippi by early afternoon and exit the service area by early 
evening. There is a very good chance for severe lightning, large hail 
and wind gusts over 60 mph. The chance for tornados now appears better 
over MS than previously thought.

*LOUISIANA:* The line of strong to severe storms should enter northwest 
LA shortly after sunrise and make its way across the entire state, not 
exiting southeast LA until early-mid evening. The networks in Central as 
well as the Egsi East and Eli South regions of Southern have the highest 
chance of experiencing severe lightning, large hail, and wind gusts over 
60 mph, along with isolated tornados. The remainder of Southern and all 
of Metro could get storms with moderate to severe lightning, wind gusts 
over 50 mph, and hail, with a slight chance of tornados.

*TEXAS:* The best chance for strong to severe storms will be in the 
eastern half of Huntsville, Woodville, Silsbee, and Orange starting just 
before sunrise in Huntsville. The threat should end by late morning as 
the storms exit into LA. Those networks could get storms with moderate 
to severe lightning, wind gusts over 50 mph, as well as some hail. The 
threat for any tornados is much lower than AR/LA/MS.
The rest of the networks still have a chance of getting some strong 
storms, as well, during the morning hours.
