Grey Skies and Gathering Clouds: Baltimore Enjoys a Quiet Sunday Before Severe Monday Storms

A Grey and Quiet Start to the Day

Baltimore residents waking up this Sunday, March 15, 2026, will find the city blanketed under a thick layer of grey clouds. As the lead editor for baltimore.news, I have been monitoring the latest atmospheric data from the National Weather Service and local radar stations. While today’s weather may seem unremarkable at first glance, it serves as the final period of relative calm before a significant storm system arrives early tomorrow. Currently, there are no active weather warnings for the city for the daylight hours, but that is expected to change quickly as we move into the start of the work week.

Morning and Afternoon Breakdown

The morning hours will remain chilly but dry, with temperatures starting in the low 40s and slowly climbing as the day progresses. By mid-afternoon, Baltimore is expected to reach a high of approximately 53°F to 56°F. While these temperatures are relatively mild for mid-March, the total absence of sunlight will make it feel considerably cooler to those walking along the Inner Harbor or attending local events. Key atmospheric details for the daytime include:

• Cloud Cover: Near 100% overcast conditions throughout the entire day.
• Wind: Steady breezes originating from the east-southeast at 10 to 15 mph.
• Humidity: Staying around 61%, creating a damp environment even before the rain begins.
• Precipitation: A low 15% to 20% chance of light sprinkles or patchy drizzle before 4:00 PM.

Evening Transitions: Rain on the Way

The atmosphere will become increasingly unstable as we head into the evening hours. By 7:00 PM, the probability of rain will begin to climb significantly. Forecasters are predicting light rain and consistent showers to move into the Baltimore metropolitan area shortly after sunset, with the chance of precipitation peaking at 75% overnight. Temperatures will stay relatively stable in the high 40s after dark, prevented from dropping further by the insulating effect of the heavy, moisture-laden cloud cover.

Looking Ahead: Monday’s Severe Weather Alert

While Sunday remains manageable for outdoor errands and travel, residents are urged to prepare for a designated First Alert Weather Day on Monday, March 16. A powerful storm system is tracking toward Maryland, bringing with it a 95% chance of heavy rain and potent thunderstorms. This system carries a risk of damaging wind gusts and even isolated tornadoes for the central Maryland region. Use today’s dry periods to secure any loose outdoor items and ensure that storm drains near your property are clear of debris.
