Maryland Weather Overview
Maryland weather radar covers a compact but complicated weather state, from Garrett County mountains to the Chesapeake Bay and Atlantic beaches. Maryland has a humid subtropical climate in the central and eastern lowlands, with cooler uplands in the west and about 43.6 inches of precipitation statewide each year. NWS Baltimore/Washington (WFO LWX) handles Maryland warnings and forecasts, so the Maryland weather radar map is especially useful for tracking storms across Baltimore, Annapolis, Frederick, Hagerstown, and Ocean City.
Flooding is the weather threat Maryland residents check most often. The Ellicott City flash floods of 2016 and 2018 showed how fast water can rise in steep Patapsco Valley terrain, while NOAA lists 14.75 inches near Jewell/Friendship in 24 hours during July 1897. Maryland weather radar helps spot slow-moving thunderstorms before roads fill with water. The June 2012 derecho also proved how quickly severe wind can cross the state, knocking out power across the Baltimore-Washington corridor.
Coastal storms and winter weather round out the risk picture. Hurricane Isabel in 2003 pushed damaging Chesapeake Bay surge into Maryland communities, and nor'easters can shift the state from rain to snow within miles. NOAA records show a 109°F Maryland high, a -40°F low at Oakland in 1912, and 31 inches of snow at Clear Spring in 1942. Use Maryland weather radar during tropical remnants, winter storms, and summer thunderstorm days; the Maryland weather radar view keeps those fast-changing patterns in one place.
Maryland Weather Risks & Safety
Nor'easter Risk
Nor'easters are Maryland's biggest multi-threat storms — heavy snow, powerful winds, and coastal flooding all at once. They track up the Eastern Seaboard from fall through early spring and can grind the city to a halt for 24 to 48 hours. On the radar you can see the precipitation bands wrapping around the storm center and track exactly where the heaviest snow or rain is falling. Past nor'easters have buried Maryland under record snowfall with widespread power outages.
Flooding & Flash Flood Risk
Flooding can develop quickly in Maryland when slow-moving thunderstorms produce intense rain. Low-lying areas and roads with poor drainage can become dangerous while rain is still falling. Check the radar to see where the heaviest rain is falling and which areas to avoid. The standing rule: turn around, don't drown. Never drive through flooded roads, even if they look shallow.
Severe Thunderstorm Risk
Thunderstorms near Maryland may bring lightning, strong winds, hail, or heavy rain. Radar helps track precipitation position and movement, but it does not by itself confirm lightning at a location or the wind and hail conditions on the ground. Read current NWS forecasts, watches, and warnings for the expected hazards and timing. If a warning covers your location, follow its shelter instructions.
Hurricane & Tropical Storm Risk
Tropical cyclones can affect Maryland when their tracks bring strong winds and heavy rain into the area. Seasonal timing and peak activity vary by ocean basin, so follow official tropical weather outlooks and local advisories. On the radar, you can track the storm's center, rain bands, and changes in precipitation as it approaches. Keep your emergency plan current and follow local guidance when a tropical storm or hurricane threatens Maryland.
Winter Storm Risk
Winter storms near Maryland can bring snow, ice, wind, and difficult travel. Radar helps show where precipitation is occurring and how it is moving, but this precipitation layer cannot reliably determine whether rain, freezing rain, or snow is reaching the ground. It also cannot show whether a road is icy. Check the local temperature forecast, current observations, National Weather Service alerts, and road reports before travelling. Follow the preparation and travel advice in official local notices.
How to Use Maryland Weather Radar
Check Current Maryland Conditions
Start with the real-time weather summary for Maryland. Temperature, wind, humidity, and sky conditions help you judge whether storms over the Chesapeake Bay, Baltimore, or western Maryland are already affecting travel.
Watch the Live Doppler Map
Use the Maryland weather radar animation to see rain, snow, and thunderstorm cells moving across I-95, I-70, US 50, and the Eastern Shore before they reach your county.
Review Hourly and 7-Day Forecasts
Scroll to the hourly forecast for storm timing, then check the 7-day outlook for nor'easters, tropical remnants, and summer thunderstorm patterns watched by NWS Baltimore/Washington.
Monitor Coastal and Winter Threats
During Chesapeake Bay surge events, winter storms, or Ocean City coastal flooding, refresh the radar often. Maryland weather can shift quickly between western snow, central rain, and Eastern Shore wind.
