The wind turns to the west around noon. Nothing in the next day and a half is wet enough to move plans for.
Colour and bar height both show how heavy the rain would look on radar. A dotted line means the model has no reading for that hour, which is not the same as no rain.
Hour by hour
Dry and warming through tomorrow

How well can the network see Webster Groves?
The nearest Doppler radar is KLSX (St. Louis, MO), 19 miles to the WNW. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Webster Groves its center is about 1,100 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Webster Groves, so low-level rotation and the leading edge of a gust front show up on it. Webster Groves is closer to its radar than 86% of US cities.
The closest instrument actually measuring the air is KCPS · St Louis/Downtown Arpt on the ASOS/AWOS network, 11 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Missouri observing network as of this build.
