The best time for the shower looks to be Wednesday morning as the short wave moves through. High temperatures Wednesday will depend on how much sun can break through the clouds.
The radar loop suggests that we will remain in a pretty constant rainfall pattern for the next several hours with some embedded pockets of heavier rainfall.
Soak up the sun Tuesday while you still can because clouds are rolling in quickly out ahead of a coastal storm that is expected to impact our area over the next couple of days.
As time continues to tick away on September, it looks as if our chances for seeing any more measurable rain this month in the greater Baltimore area are getting quite slim.
There are some clouds in the area early Thursday, and the regional radar mosaic is also showing some rain in areas south and east of Baltimore.
One look at the regional radar Friday will show the trouble that we’ll be dealing with. The Greater DC Metro Area was absolutely pummeled by heavy rain during the night, and there are still numerous Flash Flood Warnings that remain in effect.
We have a few residual showers and t-storms across the region right now, and we should be allowing for these the next couple of hours as a slow moving cold front is being held back by a weak wave of low pressure that has developed along it.
Highs Tuesday should top out in the low/mid 60s while a cool air mass is still in place.
There was a lull in activity earlier this morning as a dry slot of air wrapped its way into the circulation of the area of the pesky low pressure system over the mid-Atlantic.
High pressure has provided us with a beautiful stretch of weather but will slowly begin moving offshore Sunday.
The active pattern over the region continues as one storm system slowly departs Wednesday with a second system approaching Thursday. In the near-term, rain will continue through the first part of the day before tapering off early Wednesday afternoon.
Although recent satellite imagery shows an extensive plume of high, thin clouds Wednesday — which stretches from the Atlantic Ocean all the way back to the Ohio Valley, these will manage to break for some sun.
