BALTIMORE — A six-hour severe weather window threatens the Baltimore metropolitan area Thursday afternoon, with forecasters warning of destructive wind gusts up to 70 mph and hail reaching two inches in diameter.
The National Weather Service has issued a Weather Impact Alert for 2 p.m. to 8 p.m. Thursday. The most violent period will compress into a two-hour span between 4 p.m. and 6 p.m., when atmospheric instability peaks.
This is not a typical summer thunderstorm.
Meteorologists point to a potent upper-level disturbance colliding with a highly unstable air mass and strong wind shear. That combination creates conditions favorable for rotating storms. Isolated tornadoes remain possible.
The threat spans the I-95 corridor. Baltimore City, Baltimore County, Anne Arundel County, and Howard County all sit in the highest risk zone.
Urban flooding poses a secondary danger. Low-lying spots and poor drainage areas could see rapid water accumulation. The evening commute will likely be treacherous.
The Hour-by-Hour Breakdown
| Time Window | Threat Level | Primary Risks |
|---|---|---|
| 2 p.m. – 3 p.m. | Isolated storms develop west of the city | Brief heavy rain, lightning |
| 3 p.m. – 4 p.m. | Storms intensify, entering Baltimore County | Wind gusts to 55 mph, small hail |
| 4 p.m. – 6 p.m. | Peak intensity — most dangerous period | 70 mph gusts, 2-inch hail, tornado risk |
| 6 p.m. – 8 p.m. | Storms push east toward the Chesapeake | Diminishing winds, lingering heavy rain |
Storm chances return tonight with a secondary round of showers, though the severe threat diminishes significantly after 8 p.m.
Preparedness: What to Do Before 2 p.m.
Charge all electronic devices. Secure outdoor furniture and loose yard items. Move vehicles into covered parking if available.
Assemble emergency supplies. Flashlights, batteries, first-aid kits, and bottled water should be within reach. A NOAA weather radio serves as a critical backup when cell networks fail.
Know the difference between a watch and a warning. A watch means conditions are favorable. A warning means the hazard is imminent or occurring. Act immediately on warnings.
The safest tornado shelter in a home is an interior room on the lowest floor. Bathrooms and closets without windows offer the best protection. Avoid corners and exterior walls.
Post-Storm Protocol
Stay away from downed power lines. Assume any line is live. Check for gas leaks by smell — if you detect one, evacuate and call 911.
Document all damage with photographs before any cleanup. This evidence is essential for insurance claims. Report outages directly to BGE at 1-877-778-2222 or through their mobile app.
Avoid flooded roadways. Six inches of moving water can knock a person down. Twelve inches can carry away a vehicle.
The Thursday storm may prove the most severe of the season. The six-hour window is short, but its consequences can linger for days.
Do not wait for sirens. Review your plan now. Stock your kit now. Monitor local forecasts now.
