…Slight Risk for Severe Storms on Monday…

…Locally Heavy Rainfall Possible Tonight through Thursday…

Timing & Area of Concern:

  • This Afternoon through Tonight:  Slight risk for severe storms along and north of a Kerrville to New Braunfels to La Grange line (including Austin) and Marginal Risk south of this line (including San Antonio).  Enhanced risk for severe storms along and north of a Burnet to Georgetown line.  Locally Heavy Rainfall possible late afternoon and tonight along and north of a Kerrville to New Braunfels to La Grange line (including Austin).
  • Monday through Tuesday:  Slight risk for severe storms across all of South-Central Texas Monday and Monday night  (Includes San Antonio & Austin).  Locally heavy rainfall threat possible Monday night and Tuesday along and south of Interstate 10 (includes San Antonio)
  • Wednesday through Thursday:  Locally heavy rainfall threat possible across portions of South-Central Texas. (includes Austin and San Antonio)

Threats & Impacts:

Severe Storms
  • Hail up to golf ball sized and winds up to 60 mph
  • Threat for hail larger than golf ball sized this afternoon and tonight along and north of a Kerrville to Georgetown line (see grey hatched area in attached graphic)
  • Isolated tornadoes possible, especially this afternoon and tonight in Tornado Watch area (see attached graphic)

Rainfall & Flooding

  • Today through Thursday:  3 to 6 inches across the eastern Hill Country and along and east of the I-35 corridor.  2 to 4 inches across the western Hill Country.  1 to 3 inches across the Rio Grande.  Isolated higher amounts possible. (see attached graphic)
  • Amounts are forecast over the course of 5 days.
  • Given these these forecast rainfall amounts, along with current hydrologic conditions, localized moderate river flooding will be possible for tributaries and mainstem rivers in areas generally along and east of I-35 corridor.  In addition, a flash flood threat of smaller creeks, streams, low water crossings, and other urban areas normally subject to flooding may also may also develop.
Overview:

A moist and very unstable airmass will interact with an upper level disturbance this afternoon and tonight, leading to scattered to numerous showers and storms.  The greatest threat this afternoon and tonight will be along and north of a Del Rio to New Braunfels to La Grange line, where severe storms will be possible, capable of producing large hail, damaging straight line winds and isolated tornadoes.  Locally heavy rainfall may also occur.

A weak cold front will move into South-Central Texas on Monday, resulting in a continued risk for strong to severe storms along with locally heavy rainfall.  The heavy rainfall threat may shift along and south of I-10 Monday night into Tuesday, depending on where the cold front ends up.

Long range models continue a good chance for rainfall Wednesday into Thursday, although details in exact rainfall amounts and severe potential are low at this time.

Confidence:

  • Severe Potential this afternoon and Tonight this Weekend:  Moderate to High
  • Severe Potential Monday:  Low to Moderate
  • Flooding and Rainfall Amounts:  Moderate

Is your pet ready for severe weather?

May 9th, 2015 at 8:35 am by under Weather

 From the National Preparedness Community:

“If you are like millions of animal owners nationwide, your pet is an important member of your household. Unfortunately, animals are also affected by disaster. The likelihood that you and your animals will survive an emergency such as a fire, flood, or tornado depends largely on emergency planning done today.

Here are five easy ways to prepare your pet for an emergency:

1) Identify a shelter: Before disaster hits call your local office of emergency management to see if you will be allowed to evacuate with your pets and that there will be shelters that take people and their pets in your area. And just to be safe, track down a pet-friendly safe place for your family and pets. Most boarding kennels, veterinarians and animal shelters will need your pet’s medical records to make sure all vaccinations are current.

2) Pack a pet kit: Take pet food, bottled water, medications, veterinary records, cat litter/pan, manual can opener, food dishes, first aid kit and other supplies with you in case they’re not available later. Each pet is unqiue, but each pet needs the basics in case of an emergency. 

3) Update your pet’s ID: Make sure identification tags are up-to-date and securely fastened to your pet’s collar. If possible, attach the address and/or phone number of your evacuation site. If your pet gets lost, his tag is his ticket home. 

4) Protect your pet during a disaster: Animals have instincts about severe weather changes and will often isolate themselves if they are afraid. Bringing them inside early can stop them from running away. Even if your dogs and cats normally get along, the anxiety of an emergency situation can cause pets to act irrationally. Understanding what to expect during a disaster is crucial.

5) Keep an eye on your pet after an emergency: The behavior of your pets may change after an emergency. Normally quiet and friendly pets may become aggressive or defensive. Watch animals closely. Leash dogs and place them in a fenced yard with access to shelter and water. Familiar scents and landmarks may be altered and your pet may become confused and lost. Remember to keep taking care of them even after the disaster.

  • Amounts are forecast over the course of 7 days, with the best chances for heavier rainfall occurring Sunday and again Tuesday through Thursday.
  • Given these these forecast rainfall amounts, along with current hydrologic conditions, localized moderate river flooding will be possible for tributaries and mainstem rivers in areas generally along and east of I-35 corridor.  In addition, a flash flood threat of smaller creeks and streams may also may also develop next week for portions of the Hill Country and I-35 corridor eastward.

Strong to Severe Storms

  • Hail up to golfball sized and winds up to 60 mph possible with any isolated severe storms

Overview:

A wet pattern will develop over South-Central Texas through the weekend and much of next week.  Very moist conditions, along with continued upper level disturbances and a a surface front next week, will interact to produce several rounds of showers and storms.  Scattered showers and storms will be possible this afternoon through Saturday, with possibly numerous showers and storms on Sunday.  Chances for showers and storms will continue each day next week.  Exact timing on storms next week is uncertain, but chances are generally higher for potential heavier rainfall Tuesday through Thursday.

It should be stressed that the forecast rainfall totals above are over 7 days, and exact amounts and locations that see the highest rainfall could change in future forecasts.

Confidence:

  • 7 Day Rainfall Amounts:  Moderate
  • Timing of Heavy Rainfall:  Low to Moderate
  • Severe Potential this Weekend:  Low to Moderate

Headline:

An active weather pattern is expected through the upcoming weekend into early next week across south central Texas. Strong to severe thunderstorms are possible, along with heavy rainfall and flash flooding.

Area of Concern:

While all of south central Texas is expected to see active weather, the greatest area of concern for severe weather on Friday and Saturday will be along and west of the Interstate 35 corridor. Concerns for severe weather are then expected to shift into areas along and east of the Interstate 35 corridor on Sunday and Monday.

Record overnight rains produce “flood wave” down Colorado River

May 6th, 2015 at 9:40 am by under Weather

Record rainfall of nearly 6″ inundated northeast Travis County and areas near Elgin overnight, flooding local low-water crossings and sending a tremendous amount of water down the Colorado River.

There was a point early Wednesday morning when the Colorado River was flowing near 10,000 cubic feet per second, matching the current flow in the Grand Canyon.
