re: Let's Do It Again: Severe Threat 3/30 - Line of Severe Storms leaving SELA. AL in it now

Thanks Duke ... just texted our youngest to be aware of the possibility in North Mississippi.

Basically a triangle from Alexandria to Memphis to Pensacola. Good luck, Mississippi!

Notables from short research I just did of large moderates - these aren't all of them just some I found quickly
4/18/2013 - 120,925 sq. mi.
4/27/2014 - 119,987 sq. mi.
*Day 2 today* - 107,285 sq. mi.

Rapides Parish cancelled school for tomorrow.

DFW still looking scary overnight? Alerts tell me hail, damaging winds and tornadoes but hoping the timing knocks at least the tornadoes out while we are sleeping.

Unfortunately, for your area and a bit West, the parameters will maximize into the late night/early morning. That is why there is only a Slight Risk back in Oklahoma. Don't get lulled by placement of the risk level. You're caught in the time gap between days.

One try on the state line SE of Meridian:

Not much you can pick apart with that one. That SRH....

Let's go chase, baw. We'll stream it to the OT.











I kid....I wouldn't chase this down there followed by that line. Nope.

James Spann's afternoon update for central AL:

SIGNIFICANT SEVERE WEATHER THREAT TOMORROW NIGHT: The weather is dry across Alabama this afternoon with a partly sunny sky... temperatures are mostly in the 75-83 degree range. The sky will stay mostly fair tonight with a low in the 50s, but eyes will be to the west, where storms will form in a zone from Texas to Iowa ahead of a dynamic storm system that will bring potential for a significant wind event to the state tomorrow night.

This weather system has very strong wind fields, which will overcome limited instability to create a severe weather threat to the Deep South. SPC has expanded the "moderate risk" (level 4/5) to include areas west of a line from Florence to Birmingham to Greenville to Andalusia. The rest of the state is in an "enhanced risk" (level 3/5).

TIMING: A line of severe storms will likely push into the northwest corner of the state around 6-7 p.m. tomorrow... it will be near I-59 (Gadsden/Birmingham/Tuscaloosa) by around 11 p.m... and then it moves into the rest of East Alabama after midnight.

THREATS: There is potential for relatively widespread wind damage with the line of storms as it passes through, with winds possibly gusting to 65 mph or higher in many places. Also, a few tornadoes could spin up within the line. Some hail is possible, but that isn't a major threat with this type of system.

GRADIENT WIND: It is important to note that gradient winds (not related to thunderstorms) tomorrow afternoon and evening could gust as high as 40/50 mph. This in itself will bring potential for some downed trees and power outages.

RAIN: Rain amounts of 1-2 inches are likely for most places, and some flooding issues are possible. We don't expect as much rain as we experienced last week, however (some places saw up to 5 inches of rain with that event).

CALL TO ACTION: This has potential to be a high end wind event for much of Alabama; plan for power outages. Secure loose objects that might go flying away with strong winds. Pay close attention to severe thunderstorm warnings tomorrow night; if you live in a mobile home I would consider treating a severe thunderstorm warning like a tornado warning and be in a community shelter or business that is open and available as a shelter.

Be sure you have two reliable ways of hearing warnings (NEVER a siren)... a NOAA Weather Radio and your phone; and be sure emergency alerts are enabled on your phone. Have the free ABC 33/40 weather app installed.

The sky will clear during the day Thursday as dry air returns to the state; the high Thursday will be around 70 degrees.
