[SusieinLP]

We just had quite a downpour here. Looks like more is on the way....

[sambucol]

When is the rain going to clear out of here?

[svrwx0503]

It is amazing how heavy rain continues to re-develop across northern Brazoria and southern Ft. Bend counties after all of the activity we have already seen across these areas. Latest radar once again showing a slow increase in convection across the aforementioned areas moving north and northwest into south and southwest Harris counties. This has been a very interesting event to say the least.

[svrwx0503]

When is the rain going to clear out of here?

Things may try to settle down later this evening but additional rounds of rain will be possible through tomorrow morning. The axis of deepest moisture will be slowly shifting west away from the metro area slowly over the next 12--18 hours which should slowly move this rain out of here. It still looks like a very unsettled week around here through.
