TORNADO THREAT – LOUISIANA ARKANSAS TENNESSEE GEORGIA – 11 STATE ALERT

NWS Storm Prediction Center severe outlook November 4: Thunderstorms will have potential to produce isolated severe wind gusts and perhaps a brief tornado or two from Texas Louisiana border to mid-Mississippi Valley. Greatest severe weather risk Wednesday covers East Tennessee, eastern Alabama, southwestern North Carolina, northwestern South Carolina and much of northern and central Georgia, including Atlanta. Damaging wind gusts are expected to be main threat, but isolated tornadoes are possible beginning late Wednesday morning.

Real events today: On November 3 at 3 PM local time, NWS Shreveport issued tornado warning for Northwestern Lincoln Parish, West Central Union Parish, and East Central Claiborne Parish in Louisiana. Shortly after, Fox Weather confirmed tornado touched down in Bossier Parish, Louisiana, with debris reported near Barksdale Air Force Base area. No injuries reported but power lines down.

Total 11 states were placed on tornado alert November 3-4 night: Texas, Louisiana, Arkansas, Mississippi, Tennessee, Missouri, Iowa, Illinois, Kentucky, Alabama, Georgia. This is huge national report.

AccuWeather Senior Meteorologist Alex Sosnowski: Strongest storms could produce damaging wind gusts 50 to 60 mph, Local StormMax 75 mph. A few tornadoes, hail and flash flooding also possible. More than 21 million people across at least 7 states were at marginal to slight risk of severe thunderstorms on Monday November 3.

For today November 4, excessive rainfall threat Level 2 of 4 Slight Risk exists for 7 states: Louisiana, Arkansas, Florida, Mississippi, Tennessee, Missouri, Texas. The area of rain currently over ArkLaTex into Missouri will push into Slight Risk area late this afternoon evening.

Heavy to excessive rainfall will continue today across portions of Southwest and Four Corners Region, leading to flash, urban and small stream flooding. Significant river flooding expected through Monday. 15 river gauges in Arizona, Colorado and New Mexico set all-time record crests November 1. San Juan River at Pagosa Springs crested 19.71 feet, breaking old record 17.8 feet.

WARM AND HUMID – 78F WARM AND WINDY EAST COAST BEFORE RAIN

While West is -4F snow, East Coast is 78F warm, windy and humid before rain. This temperature contrast is driving severe weather.

Weather.com notes: November begins with unseasonable warmth across much of US, particularly warm for middle of nation. Afternoon temperatures from Texas to Minnesota on Monday November 3 were as much as 10 to 20 degrees or more above average. Eastern US from Florida to Washington DC to New York recorded 75 to 78F on November 3, which is 15F above normal for November.

This warm moist air from Gulf of Mexico is feeding severe storms. Humidity dew points in 65-70F range in Louisiana, Mississippi, Alabama, Georgia are more typical of August, not November. That is why tornadoes are possible in November – unusually warm.

But cold front will break warmth. Behind front, temperatures will drop to chilly side from Northwest to Rockies and far northern upper Midwest, but rebound by afternoon. East Coast will stay warm until Thursday, then heavy rain arrives.

FLORIDA FLOODING AFTERMATH

No USA national report is complete without Florida. As of November 4, Florida remains under emergency.

Hundreds rescued, 2 dead in Brevard and Broward, White City area south of Fort Pierce homes flooded around South 25th Street and Bell Avenue November 3.

Tree limbs could be blown down and few power outages may result. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.

SAFETY FOR THIS WEEK
