Here's a link to a webpage that may make your life easier. I get my basic weather forecasts from Weather Underground, which offers up a nice presentation of the info and predictions issued by the National Weather Service…and that site is helpful but I wanted to link you to one page in particular over there.
It's this one. They call it the WunderMap® and it's an interactive radar map on which you can find your address and see storms in your area. It's been raining here in L.A. the last few days and I've been keeping an eye on it. I can actually look at that map and say with reasonable certainty things like, "We're going to have light rain here in about twenty minutes and it'll last about thirty minutes then clear out." The other day, I figured out the perfect time to get out of the house, walk up to a market and get back home before the showers resumed. The main part of the site can tell you the forecast for tonight or tomorrow or next Tuesday…but the WunderMap® enables you to get a pretty educated guess on any precipitation in a chosen area for the next hour or two.
You'll need to enter the address and to then use the little control that lets you animate the radar maps. This will show you recent radar pictures in sequence overlaid on a map of your area. Note the time stamps on them. It should be something like one picture every five minutes. By zooming in and out on the map, you can get a sense of where the storms are around you, which direction they're moving and how fast they're moving. It's not infallible, in part because you're not infallible…but if you study it a bit, you should understand how you can read it to get valuable information. This kind of map is available elsewhere on the 'net, including on some sites that charge hefty subscription fees. This is free…and for a very small amount, you can join and access an enhanced, adless version of the website that's even better. It's a handy thing to have available.
