Happy Sunday night,
Confidence is increasing in a significant severe weather threat Monday, March 16th across Maryland. The Storm Prediction Center has issued a rare Level 4 out of 5 (Moderate Risk) for severe storms. The last time a risk this high was issued for parts of our area was August 7, 2023.
Overnight tonight, a warm front will lift northward, increasing low-level moisture across the region. At the same time, a dip in the jet stream will strengthen winds aloft. The combination of moist air at the surface and strong winds higher in the atmosphere will create an environment capable of producing large hail, damaging winds, and a few tornadoes.
The greatest threat appears to be between 2 PM and 8 PM, when a squall line moves from west to east across Maryland. These lines of storms are notorious for producing powerful straight-line winds, which could gust between 60–75 mph.
Now is a good time to review your severe weather safety plan and make sure you and your family are prepared.
Stay weather aware tomorrow.
