Meteor Captured on Radar

5:45 PM Mon, Feb 16, 2009 |
Mark Murray

At 11:03 am Sunday morning, a meteor streaked across our Texas sky. It was traveling at an estimated 15,000 to 40,000 miles per hour. It was captured by two National Weather Service Doppler radars as it passed about 20 miles north of Waco, or about 120 miles north of Austin. The image on the left was taken by the NWS Fort Worth radar as the radar beam was about 4,000 feet above the ground. The image on the right was taken when the radar beam was about 7,000 feet above the ground.

The National Weather Service Doppler radar in Granger, Texas (Williamson County) also saw the meteor. The image on the right was taken when the radar beam was about 9,000 feet off the ground. The image on the left was taken when the radar beam was about 14,000 feet above the ground.

Risk of Severe Weather on Tuesday

9:39 PM Mon, Feb 09, 2009 |
Mark Murray

Even though much of our severe weather occurs in the Spring, we all know that dangerous storms can strike during any month of the year. It looks like parts of Texas will be under the threat of severe weather from late Tuesday afternoon into the early morning hours Wednesday.

Tonight's computer model runs place the track of the upper-level low pressure just to our north for Tuesday evening. That would mean North Texas and Oklahoma would be under the greatest risk for damaging winds, large hail, and tornadoes. It's possible, that if the low were to drop just a bit farther to the south, that parts of Central Texas could see a few strong storms. The Tuesday forecast calls for cloudy skies which would limit daytime heating. If we see breaks in the clouds during the afternoon, the additional heating would make our atmosphere much more unstable, increasing our risk of storms in the Austin area. We'll also be closely watching the speed of the low. If it comes in faster than expected, that will also increase our threat of severe weather, because it will cross Central Texas closer to the warmest time of the day. If it doesn't reach us until late evening (which is what I expect), than that will lower the risk.

For now, the Storm Prediction Center has placed us under a "Slight Risk" of severe weather. Keep up to date with the latest on KVUE or on www.kvue.com.

Cedar Fever Season Update

"When will Cedar Season End?!?"

Good news, John! The worst of cedar season is behind us! It's rare that we see high cedar pollen levels after February 5th. We could still see some medium counts over the next week or 10 days, with low cedar counts through the end of the month!

It's about time!
