![]() Stage two water restrictions have started and will continue for the foreseeable future. Lake Buchanan is steady with an elevation of 994.04 feet (46% full, 16.5 feet below average)Ĭombined storage is still below 900,000 acre-feet. Lake Travis is falling with an elevation of 630.88 feet (39% full, 35 feet below average) ![]() We currently have just a 20% rain chance with an otherwise cloudy and mild day in store with morning 60s and afternoon 70s on tap. forecast, weather conditions and Doppler radar from The. While there will still be some energy & lift in our local atmosphere, it looks like moisture won’t be in great supply for additional rain. Check out our current live radar and weather forecasts for Austin, Texas to help plan your day. That’s another half inch to one inch of rain falling through the day.ĬHRISTMAS DAY - The forecast for Christmas day itself in Central Texas is a bit uncertain at the moment, but it is trending drier as of this writing. Depending on the timing and path of that system, rain chances could increase further. This will be your best day of the Holiday weekend to get some last-minute shopping done or head to one of the many holiday events taking place across Central Texas.ĬHRISTMAS EVE - The lion’s share of the second (stronger) storm system will roll into Texas on Sunday with a 50-60% chance for showers and storms. SATURDAY - We’re bringing rain chances down on Saturday to just 30% as storm system #1 departs to the east and storm system #2 approaches from the west. A quick half inch of rain is possible for some, especially from Austin to the northeast. THURSDAY - The first of two storm systems will swing through the northern end of Texas, and with that comes an increased 40% chance for more substantial (but still light) rain showers especially through the afternoon and evening.įRIDAY - 50% rain chance through the middle of the day could come with a stray storm or two. That’s a 30% rain chance, though no meaningful accumulation is expected and you’ll otherwise be just fine without the rain gear. The National Weather Service in Austin/San Antonio has issued a At 729 PM CDT, Doppler radar indicated thunderstorms. ![]() WEDNESDAY - Southerly winds are back and will bring in enough moisture to get some light drizzle to develop in the morning hours. Temperatures will be familiar with morning lows in the low 40s and highs in the upper 60s. We’ll keep the forecast quiet through Tuesday as well, though you’ll notice much more upper-level cloud cover loading up overhead. For the non-allergic among you, it was some 10/10 December weather for Central Texas. You may not have wanted to be outside though considering the spike in Cedar pollen that came with the dry and (at times) breezy air behind the front. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.The incredible weekend weather continued Monday, albeit a bit cooler behind a weak cold front with highs in the 60s. Hail is a good reflector of energy and will return very high dBZ values. Contact the helpdesk for operational issues. Review the Radar FAQ for help with the transition to the new site. The radar products are also available as OGC compliant services to use in your application. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. The NWS Radar site displays the radar on a map along with forecast and alerts. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
