Flash flooding is possible as severe storms and rain showers move across the Baltimore region Monday afternoon and evening, marking the start of a period of wet weather forecast this week.
A flash flood watch was in effect through 10 p.m. and a severe storm watch was in place through 11 p.m. across Central Maryland. Widespread showers and thunderstorms were forecast to develop along a stalled front hanging over the Mid-Atlantic.
The National Weather Service wrote on Twitter Monday night that while the area might see some isolated showers and thunderstorms, “additional severe weather is not expected.”
That pattern of stormy weather is expected to “repeat itself each day through Thursday,” National Weather Service meteorologist Luis Rosa said.
Severe thunderstorm warnings were issued in parts of Anne Arundel, Howard and Baltimore counties and Baltimore City around 4:30 p.m. Monday. Meteorologists warned 60 mph winds and 1-inch hail could be possible in the storms.
They also said some areas could see flooding rain. A widespread quarter to half inch of rain is forecast Monday afternoon and evening, but meteorologists warned that some areas could see significantly more rainfall in short periods of time.
“There is potential for showers to move repeatedly over the same areas and to produce intense rainfall rates in a short period of time that may lead to flash flooding,” meteorologists warned.
Rising heat and humidity was expected to fuel storms and downpours, meteorologists said. Temperatures reached 90 degrees by 1 p.m. at Baltimore-Washington International Thurgood Marshall Airport, and with humidity factored in, it felt like 92 degrees.
The flash flood watch is in effect in Carroll, Baltimore and Harford counties and in Baltimore City. The severe storm watch is in effect in Baltimore, Anne Arundel and Harford counties and Baltimore City.
