The calm before the rainstorm

How much rain do you think will fall?

After some showers in the afternoon, we have a brief in the lull in the rain - auspiciously timed to allow the final home game at Nationals Park this evening. But a massive shield of rain fed by moisture deep into the tropics (cool water vapor loop) lurks to the south.

We're sticking with our prediction for a general 2-4" rainfall event (with some locally higher amounts), but NOAA's Hydrometeorological Prediction Center is a little more aggressive: forecasting 3-6" (with some potential for 6-10" totals). The heaviest rain is expected between about 4 a.m and 10 a.m.
