Daily chances for afternoon and evening thunderstorms exist through the rest of this week. Some storms may be strong to marginally severe in nature with damaging winds, torrential rainfall, small hail and frequent lightning.
While widespread severe weather is not expected, it is important to stay tuned to your favorite local weather app in case a Warning needs to be issued. You can also follow us on Twitter for automated alerts.
Primary Hazard(s): Heavy rainfall leading to flooding, severe thunderstorms capable of 60+ MPH winds
Secondary Hazard(s): Tornadoes
Confidence in Hazard(s): High
SUMMARY:
On Tuesday, severe thunderstorms are possible mainly for central Alabama, with the primary hazards being damaging winds although tornadoes cannot be ruled out. A greater risk more widespread damaging wind gusts will be for areas Pelham points south. Currently, an Enhanced Risk (Level 3/5) is in place for these areas. For the Slight Risk and Marginal Risk areas, this will be a conditional threat. There will also be a great concern for flash flooding as heavy amounts of rainfall move through.
On Wednesday afternoon, a more widespread threat of severe weather is possible state-wide, especially across north-central Alabama. The potential exists for all modes of severe weather, including tornadoes, damaging winds and hail.
PRIMARY HAZARD(S): Non-thunderstorm winds of 25-35 MPH, gusts as high as 50 MPH. Destructive thunderstorm winds of 60-80 MPH associated with thunderstorms.
SECONDARY HAZARD(S): Tornadoes
Potential Impacts: Winds of 25-57 MPH can cause tree limbs to fall onto power lines and result in power outages. Winds of this magnitude can also blow around loose, unsecured furniture. Winds of 58 MPH or higher start causing damage to roofs, siding, and trees.
A few brief tornadoes are also possible as the line moves through. Tornadoes can cause damage to vehicles, structures and harm people. Know what to do when a Warning is issued.
Confidence in Hazard(s): High
SUMMARY: A vigorous line of strong to severe thunderstorms will move across the region Wednesday evening and Wednesday night. Parts of the area have been highlighted in a MODERATE RISK (Level 4/5) for severe weather. The rest of the Coverage Area is in an ENHANCED RISK (Level 3/5). Bottom line, the entire southeast will see severe weather tomorrow afternoon and evening.
DISCUSSION:
SPC highlights, model ensembles continue to hint at a fairly widespread damaging wind event shaping up for Wednesday afternoon into the night. No longer looking at it rolling into Thursday except for perhaps the eastern part of the state outside of our Coverage Area due to the speed of the line of thunderstorms.
SUMMARY: Gusty winds, severe thunderstorms which may include large hail and winds of 60-70 MPH, flash flooding, and tornadoes are all possible Tuesday evening into Wednesday morning – especially across our western/southwest Coverage Area. Tomorrow is a day to stay weather aware anywhere in the state and not to stay too focused on the colors of Outlooks. They are only a point of reference as severe weather will be possible anywhere in the state tomorrow evening into Wednesday morning.
DISCUSSION: Forecast guidance continues to show the potential for an all-episode severe weather outbreak across central/south Mississippi Tuesday afternoon, and lingering into west/southwest Alabama by the evening. The slow progression of the system will also lead to a flooding threat. As the system approaches from the west, winds will begin to increase into the 25-35 MPH range.
In addition to the threat of severe storms, most of the Coverage Area has been placed in a Moderate Risk for excessive rainfall:
SUMMARY: Warm gulf moisture will aid in severe thunderstorms development Friday morning and again in the afternoon. The primary risk with round 1 will be damaging winds of 50+ MPH, with round 2 all modes of severe weather are possible, including tornadoes, large hail, and damaging winds. This will greatly depend on how much the atmosphere destabilizes after round 1. Flash flooding will be a threat for portions of central Alabama that have received heavy rainfall.
SUMMARY: North Alabama has been upgraded to a Winter Storm Warning, with central Alabama remaining under a Winter Weather Advisory. Total snow accumulations will range from 2-4″, with the highest amounts close to the Tennessee state line. Lesser amounts from 1-2″ are possible from Cullman County points south.
DISCUSSION: Winds will begin to increase overnight ahead of the cold front, with moisture quickly following. Precipitation will begin as all rain then change over to snow/sleet then eventually change over to all snow. The snow and sleet may be heavy at times. Temperatures are not expected to rise above freezing on Saturday. Expect surface temps to bottom out and fall below freezing overnight, with bridges and overpasses first. Travel may become difficult due to slick spots.
Additionally, sustained winds of 20 MPH will be possible with the passage of the cold front, with gusts over 40 MPH, especially in higher terrain.
RECOMMENDED ACTIONS: Prepare for power outages due to high winds, plan on slippery road conditions and sudden drops in visibility. Slow down and use caution if you must drive Saturday morning.

SUMMARY: In addition to the threat of flooding, thunderstorms that develop this evening will be capable of damaging winds and a few tornadoes.
DISCUSSION: A line of strong to severe thunderstorms will approach from the north this evening. Conditions will be favorable for the development of severe storms within the line and a few tornadoes – especially if isolated cells form ahead of the main line. Looking at model data, this scenario is possible.
As previously posted, a Flood Watch is also in effect for northern Alabama this afternoon through midnight Wednesday.
SUMMARY: Moderate to heavy rainfall will cause rainfall amounts from 2-5 inches, with isolated higher amounts. This will cause flooding issues, especially in flood-prone and low-lying areas.
DISCUSSION: Flood Watch goes into effect at midnight tonight and goes until midnight Friday for north Alabama, and until 6:00 AM for central Alabama. This system is moisture that is feeding a vigorous winter storm system to our north.
