The main story for today is how tranquil it will be compared to previous days. The bulk of the day will be rain-free with sunshine returning to Maryland and it will feel comfortable as dew point values reside in the upper-60s and low-70s. Daytime high temperatures climb to the mid and upper-80s this afternoon, which is seasonable for this time of year.
As a front crosses through the region today, it will eventually stall out near Delmarva later tonight. This will help rain showers and isolated thunderstorms fire up from southwest to northeast around midnight which will linger into Thursday morning.
The areas that will most likely see showers and isolated thunderstorms will be around the Inner Harbor, Annapolis, across our northwestern counties, and areas along the Eastern Shore. Rainfall amounts may range anywhere from .25-1". The threat for severe weather is low but periods of heavy rainfall are possible so that might cause issues for areas that already received a significant amount of rain from Isaias yesterday.
As the frontal boundary stalls out to the southeast of Delmarva and remains in the vicinity through Thursday, it will keep extra clouds around and the chance for scattered showers and thunderstorms. As of right now, it is not looking like a total washout, but localized flooding is definitely not out of the question for flood-prone areas.
