Increased instability and humid conditions will put Baltimore at risk for a shower or thunderstorm Monday, particularly during the afternoon and evening hours.
Aside from spotty showers and thunderstorms, the first half of the night likely turns out dry in Baltimore. Things will begin to turn by the second half of the night as a robust southwesterly flow leads to deepened moisture.
Showers and thunderstorms could begin as early as 1 or 2 a.m. around the Baltimore Metro, increasing in coverage toward daybreak. With P-WAT values exceeding 2.00 inches, it is worth mentioning the threat for localized flooding, especially in low-lying and poor drainage areas. A general 0.25 to 0.50 of an inch of rain is expected with locally higher amounts.
All in all, it could be a difficult and slow-going Tuesday morning commute.
A couple of showers and thunderstorms could linger into the afternoon and evening hours, however the bulk of the activity will occur during the morning.
