Weather Update from National Weather Service

Posted By Roy Sedwick, Friday, January 3, 2014

Good afternoon TFMA – hope all of you survived the New Year celebrations.  I know it was hard to go back to work and start with a whole fresh new year, But isn’t it exciting to think about the possibilities and successes that 2014 will bring? Just wanted to give you  a heads up that we are going to be hit by some very frigid air coming in Sunday night into Monday and Tuesday of next week.  I am talking low teen’s.  Very cold!!!!!  At least no ice or snow is forecast.  With extended hours of below freezing, danger and risks increase for the four P’s – People, Pets, Pipes and Plants. If your community has a homeless population that often sleep outdoors, especially under bridges, etc., make an extra effort to warn these individuals and try to get them into shelters if possible.  Also, as good neighbors, please check on the elderly and handicap as they may need some help with extra blankets, a heater, some warm soup, etc.  Bring in pets and wrap exposed pipes.  A $2.00 dollar faucet cover is very cheap compared to the price of a flooded home from broken pipes.  And flood insurance doesn’t cover that type of flood!

Please review the three weather updates below and maintain contact with local media and the National Weather Service via NOAA All Hazards Radio or via their websites.  Stay warm and safe my friends.  We have a great new year to look forward to.  Thanks for your support

 Subject: Weather Update from National Weather Service -- Hard Freeze Next Monday/Tuesday South Central Texas Partners...

...HEADLINE...Arctic air outbreak early next week -- coldest conditions since February 2011.

...AREA OF CONCERN...The entire area, but especially the Hill Country and low-lying locations in river valleys along and east of I-35 (such as Austin Bergstrom).

...IMPACTS...Low temperatures in the teens in the Hill Country, and lower to mid-20s most other locations in the early morning hours on Monday and Tuesday. Our safety tips revolve around the 4 P's: People, Pets, Plants, and Pipes. People and pets will need to be indoors Sunday night into Monday and Monday night into Tuesday. Expect spikes in the homeless seeking shelters. Plants should be brought indoors if possible. Covering plants may be effective for hardier types, but may not work in some cases with temperatures below freezing for 10-14 hours each morning. Pipes are a concern in the Hill Country or in exposed situations such as mobile homes near rivers or streams. Usually 9 consecutive hours of temperatures at or below 21 F is enough for unprotected pipes to burst. Covering outdoor faucets, opening up indoor cabinets for warm air flow under sinks, flushing the water out of sprinkler systems, and wrapping exposed pipes offer protection.

...TIMING...Temperatures will be below 28 F from midnight until 10 am both Monday and Tuesday mornings.

...DISCUSSION...A strong cold front will usher in the coldest air since February 2011 into the region. It will be much worse for locations in the northern half of the U.S. -- be glad we live in Texas. Temperatures will fall well below freezing and stay there for 10-14 hours both Monday and Tuesday mornings. There will not be much wind (especially Tuesday), but wind chills will still fall into the single digits in the Hill Country to the lower teens elsewhere. People should at minimum wear hats, even better wearing gloves or mittens and covering their face (a handkerchief tied off in bank robber style works well). Hypothermia and frostbite should only be a problem with many hours of outside exposure.

Operational Weather Brief; Very Cold Temperatures Expected Early Next Week--Friday, 01/03

From LCRA – Bob Rose

Here is an update on weather conditions for this weekend and next week.  A strong arctic cold front will be moving across the region Saturday night into Sunday morning bringing much colder air to Central Texas that will last through next Tuesday.  This is shaping up to be some very chilly air!  For many locations, temperatures Monday night into Tuesday morning will be the coldest we’ve seen since the cold outbreak in February, 2011.  And to review, In February of 2011, the temperature at Austin-Camp Mabry reached 19 degrees and at Austin-Bergstrom, the temperature reached 16 degrees.  Fortunately, there will not be any precipitation with this cold air and milder readings will begin returning late Tuesday into Wednesday. For today and Saturday, the weather will be mostly sunny.  Southerly breezes will develop late this afternoon and this evening with speeds of 10-15 mph.  Today’s temperature is expected to warm to the middle 50s.  Lows Saturday morning will be in the upper 30s to low 40s.  Breezy and milder weather will be in place Saturday as southerly winds increase to 10-20 mph with gusts to 30 mph.  Expect a high temperature in the upper 60s. But a strong arctic cold front is forecast to drop south across the Plains states on Saturday, reaching the northern Hill Country by about midnight Saturday night.  The front will continue pressing south, moving across the Austin area around 3 am and clearing the middle Texas coast just after sunrise on Sunday.  No rain is expected with the cold front when it moves across the Hill Country or Central Texas regions but a few light showers may develop when it moves across the coastal plains.  Rain amounts, if any, will be very low.  Windy and much colder weather will develop behind the cold front Saturday night.  Lows Sunday morning will  be near 28-30 degrees across the Hill Country, in the mid and upper 30s across Central Texas and in the mid 40s across the coastal plains. Sunday’s weather will be sunny, windy and cold with northerly winds at 15-25 mph throughout the day.  The high temperature will range from about 40 degrees across the northern Hill Country to the low and mid 40s across Central Texas to the upper 40s across the coastal plains.  Wind speeds look to decrease some Sunday night, allowing for the development of very cold temperatures.  I expect a freeze at all locations.  Lows Monday morning are forecast to be near 20-23 degrees across the Hill Country, near 23-25 degrees across Central Texas and the upper 20s across the coastal plains. Monday’s weather will be sunny and cold as a reinforcing shot of arctic air spreads south across the area.  High temperatures will be in the upper 30s across the northern Hill Country, near 40-42 degrees across Central Texas and the mid to upper 40s towards the coast. With a clear sky and light winds, the temperature will turn quite cold Monday night into Tuesday morning.  I expect a hard freeze again at all locations.  Lows Tuesday morning are forecast to be near 17-22 degrees across the Hill Country, near 20-24 degrees across Central Texas and near 25-28 degrees across the coastal plains region.  Much of the Hill Country and Central Texas could see a freeze duration of 6 to 10 hours Monday night into Tuesday morning. Tuesday’s weather will be mostly sunny and continued cold with high temperatures in the low and mid 40s.  But scattered clouds and southerly breezes are forecast to return Tuesday night.  Both of these factors should lead to warmer temperatures Tuesday night.  Lows Wednesday morning will range from the low 30s across the Hill Country to the low 40s across the coastal plains. The weather for next Wednesday through Friday is shaping up to be mostly cloudy and a little warmer.  A developing trough of low pressure over the southwestern US is expected to pull clouds and moisture inland from the Gulf of Mexico.  We may see the development of some scattered light rain showers Wednesday through Friday.  High temperatures all 3 days will be in the upper 50s to low 60s.  Low temperatures will be in the 40s.  Long-range forecast solutions call for an increasing chance for rain and thunderstorms across the region next Friday through Saturday when the upper trough moves across Texas. Have a good weekend and stay warm.

Incoming Cold Air Outbreak

 Widespread freeze ongoing this morning across the area with lows down into the mid 20’s from Conroe to Huntsville and NE toward Lake Livingston. However a much bigger and stronger cold snap is on the way for early next week.  Upper level pattern will remain amplified through the period with high pressure ridging over the eastern Pacific into Alaska which will send another shot of very cold arctic air southward this weekend. Models continue to come in colder and colder with this air mass as more of the air mass pours southward down this plains before shifting eastward. This air mass means business and may set low temperature records in the northern plains which for January is very impressive…the forecast high temperature for Fargo, ND early next week is around -20F. Arctic boundary will plow through the region on Sunday with temperatures quickly falling into the 30’s and 40’s during the day. Luckily winds will stay up Sunday night, but still expect a widespread freeze and wind chill values into the 10’s and 20’s over the entire region.  Big concern is Monday night into Tuesday morning as arctic high builds overhead and winds go nearly calm under clear skies and very low dewpoints (8-16 degrees over the area). Expect temperatures to fall below freezing shortly after sunset and remain below freezing for up to 12-15 hours. Looks like lows could fall into the upper 10’s across our northern counties with low to mid 20’s along the US 59 corridor and even freezing at the coast. Will likely need a hard freeze warning for most areas for next Monday night as many areas will fall below 25 degrees for more than 2 hours. Tropical plants will need protection along with any exposed outdoor pipes and sprinkler systems. We are still a good bit of time before the event so temperatures could trend upward or downward over the weekend…but residents should take advantage of the "warmer” weather on Saturday to prepare for the upcoming very cold conditions.  Large arctic high begins to shift eastward next Wednesday allowing a moderation of temperatures and a return of moisture and possibly some low rain chances to the region.
