Baltimore, Maryland – A cooler weather pattern is expected to settle across Maryland from July 23 through July 27, bringing temperatures below seasonal averages while rainfall is projected to remain close to normal statewide. After stretches of typical midsummer warmth, residents can expect several days of milder afternoons, cooler mornings and reduced humidity, with only periodic opportunities for showers.
According to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, in its 6-10 Day Outlook issued July 17, Maryland is favored to experience below-normal temperatures throughout the July 23-27 period. The state also falls within a near-normal precipitation zone, indicating there is no strong climate signal favoring either unusually wet or unusually dry conditions.
In Baltimore, cooler Canadian air filtering into the Mid-Atlantic is expected to hold afternoon temperatures several degrees below what is typical for late July. Lower humidity levels should make conditions noticeably more comfortable for commuters, outdoor workers and anyone spending time outside. While weak weather disturbances could produce scattered showers during the five-day period, rainfall is expected to remain close to seasonal averages, limiting the risk of widespread flooding.
Farther west, Frederick is expected to experience similar conditions, with below-average daytime highs and refreshing overnight lows. The cooler air mass will be especially noticeable during the morning hours, while afternoon temperatures remain comfortable compared to normal late-July standards. Occasional clouds and isolated showers are possible, but the current outlook does not indicate prolonged periods of rain or significant storm activity.
The cooler trend is expected to extend across the entire state, including Annapolis, Hagerstown, Salisbury, Cumberland and communities along the Chesapeake Bay and Eastern Shore. Coastal areas may remain slightly cooler thanks to breezes off the Bay and Atlantic Ocean, while western Maryland could see the largest departures below average, particularly during the overnight hours.
Although the Climate Prediction Center outlook does not pinpoint the exact timing of individual cold fronts or passing showers, confidence continues to increase that Maryland will remain in a cooler-than-normal pattern through July 27. Forecast updates from the National Weather Service will provide additional detail on daily temperatures and rain chances as the period approaches, but current guidance points toward an extended stretch of comfortable midsummer weather rather than a return to prolonged heat.
