Delayed floods

Awoke to find it had not rained overnight at all at the rancho, nor much of anywhere else around the Austin area. Big areas of storms still on the radar but still west of the Hill Country. Forecasts, however, bring it all in here by mid-day, just in time for Mr. Boy’s pickup from school, with rainfall rates of 1 to 4 inches an hour. So it’s too early to accuse the meteorologists of crying wolf.

Training storms

Storms hooked together one after another like a train, moving southwest to northeast, is what we’re expected to get overnight, according to the weather service’s Flash Flood Watch statement. Rainfall rates in excess of 2 inches an hour with isolated rain totals of 3 to 5 inches possible by morning.

Radar watching

Keeping up with the approaching storms listening to the bouncing of the ball Mr. B. is playing with in his room. The weather service’s Web radar is the best. Hope it keeps working. It sometimes picks storm events to crash. If it does I can watch them on KXAN and KVUE, though they are thirty minutes to an hour behind, to the weather service’s twelves minutes or so.

I saw the last batch on the service radar coming swiftly from the southeast, so when I went to the grocery I was probably the only person in that store not to be surprised when I came out and it was pouring. Soon stopped and I hardly got wet. But the western storms, some of which have already dropped almost 6 inches in the San Saba River, northwest of us, are moving much more slowly. Since they’re due to continue east through tomorrow night, it’s not hard to believe in river flooding. No rivers around the rancho, fortunately. The Guadalupe and Colorado well south of us are the likely candidates.

Historical preciptable water

National Weather Service has an ominous few lines in its weather discussion. We’ve already had one fast-moving set of storms with no thunder or lightning but plenty of sudden, short rain:

MODELS CONTINUE TO SHOW PW (Preciptable Water) LEVELS CLOSE TO HISTORICAL RECORDS…. THIS DOES NOT NECESSARILY TRANSLATE TO HISTORICAL FLOODING AS MARCH IS NOT CLIMATOLOGICALLY ONE OF OUR PEAK FLOODING MONTHS. THE CONTINUOUS THREAT OF RAIN SHOULD EVENTUALLY TRANSLATE TO A THREAT OF MAINSTEM RIVER FLOODING WITH THE WEST TO EAST PROGRESSION OF RAIN LIKELY TO HAVE A LARGER INFLUENCE OVER THE EASTERN HILL COUNTRY AND I-35 CORRIDOR AREAS. 

Flash floods possible

Tonight’s forecast storms–brought to us by a low pressure system moving in from the west and colliding with an atmosphere laden with moisture from the Pacific and the Gulf of Mexico–could be memorable, according to Bob Rose. He was predicting on Friday 2 to 4 inches across the Hill Country, and that was still in other forecasts last night and this morning. The only problem is the ground is still wet from recent rains, so creeks and streams could rise rapidly enough for some flash flooding.

Road warriors

Forecast for tomorrow morning’s 30th annual Capitol 10K is cloudy, mid-60s and very humid with spotty showers. Courtesy of LCRA meteorologist Bob Rose who will be running his 18th race. I’ve managed to not run in every one of them, since their inception in 1977, though I have observed many a finish line. This year I believe I’ll vacuum fallen live oak leaves while Mom takes Number One Son to his tennis lessons.

Clouds streaming overhead

Wind from the southeast at about 15 mph is bringing in lots of moisture in clouds off the Gulf of Mexico, while a low pressure system out west is sucking in Pacific moisture and clouds from off the Baja Penninsula. Clouds just flowing across the rancho tonight, from the southeast, and it’s still 70 degrees. Not much rain expected, tho, until the low moves east on Saturday and Sunday, and then as it will only skirt us, just a moderate inch or so. Would be nice to have several inches, but it isn’t to be, apparently. Following Bob Rose’s forecast on Tuesday rather nicely.
