Texas heat wave smashes more records; 93L more organized

Texas' Texas-sized drought and heat wave is setting new records, as August temperatures regularly topping 100° continue to impact most of the state. The high temperature hit 102° at the Houston Intercontinental Airport yesterday, a record for the date, and the 16th consecutive day of 100°+ heat. The 16-day streak is a new record. The previous record was 14 straight days, ending on July 19, 1980.

The low temperature yesterday morning at Dallas/Fort Worth International was 86°--the all-time highest minimum temperature recorded there. This is the 4th time this summer Dallas has had an 86° minimum temperature, with the other dates being July 26, August 3, and August 4. Prior to this year, the hottest minimum temperature ever recorded in Dallas was 85° on September 1, 1939 (which they also matched this summer on July 25, August 7, and again this morning.) Thus Dallas has matched or exceeded their all-time hottest minimum temperature from previous years seven times this year. It's extremely rare for a station with a long observation history spanning more than fifty years to break an all-time record seven times in one year; if anyone can find an example of this in the past, I'd love to hear about it. The National Climatic Data Center records page is a good place to look. Dallas has had 40 days with a minimum temperature of 80° or higher this year, breaking the previous record of 39 days, set in 1998. Dallas had a streak of 40 straight days with a maximum temperature above 100° which ended August 10, good for 2nd place all-time, next to a 42-day streak in 1980.


Figure 1. The amount of rain needed to break the Texas drought is in excess of 15 inches (purple colors) over most of the state. This year's drought is officially Texas' worst one-year drought on record. Image credit: NOAA/NWS.

According to the National Climatic Data Center, twelve other major airports set or tied their all-time high minimum temperature two or more times this summer: San Angelo, TX (four times); Lake Charles, LA (three times); Bristol, TN; Indianapolis, IN; Trenton, NJ; Newark, NJ; West Palm Beach, FL; Shreveport, LA; Beckley, WV; Texarkana, AR; Lake Charles, LA; Lubbock, TX; plus, Fort Worth Meacham Field. This year's total of fourteen airports that broke their all-time high minimum temperature multiple times this summer is similar to last year's total of ten sites. Most notable last year was West Palm Beach, Florida, which tied it's all-time high minimum temperature of 83° five times in 2010.

Fifteen major airports have tied or broken their all-time highest temperature multiple times this summer: Tyler, TX (three times); Tallahassee, FL (three times); Fort Smith, AR; Harrison, AR; Tulsa, OK; McAlester, OK; Longview, TX; and Oklahoma City, OK, Ypsilanti, MI; Altoona, PA; Dubois, PA; Salisbury, MD; Raton, NM; Amarillo, TX; and Dalhart, TX. For comparison, only three stations broke their all-time maximum temperature record multiple times in 2010: Wilmington, DE; Norfolk, VA; and Richmond, VA.

Caribbean disturbance 93L
A westward-moving tropical wave in the Central Caribbean a few hundred miles south of Hispaniola, Invest 93L, has increased in organization overnight, building up a modest amount of heavy thunderstorms. Low-level spiral bands have begun to form on all sides of the storm this morning. There are currently no signs of a surface circulation, though there is plenty of large-scale rotation apparent on satellite imagery. Dry air surrounds 93L and has infiltrated the center of the disturbance, giving 93L a doughnut-like appearance. However, the disturbance is steadily moistening its environment and is under low wind shear of 5 - 10 knots, so this dry air should gradually mix out today and allow 93L to continue to organize. There is a hurricane hunter mission scheduled for this afternoon at 2pm EDT to see if a tropical depression is forming.

93L will bring heavy rain showers to southern Haiti this afternoon and to Jamaica tonight. By Thursday, 93L's forward motion will slow to 10 - 15 mph, and the storm will bring heavy rains to Northern Honduras and Northeast Nicaragua. These rains will spread to Belize and Mexico's Yucatan Peninsula by Saturday. The latest SHIPS model forecast shows wind shear remaining in the low range and the atmosphere steadily moistening as 93L enters the Western Caribbean on Thursday. All of the models agree that the ridge of high pressure steering 93L to the west will remain strong, forcing the storm into a landfall Friday in Northeast Nicaragua or Northeast Honduras. It is possible that 93L will have time to intensify into a Category 1 hurricane before then, though landfall as a tropical storm would be more likely, given the dry air that 93L needs to overcome. Regardless of development, the storm will bring very heavy rains of 4 - 8 inches or more to Nicaragua and Honduras. These rains are likely to cause dangerous flash flooding and mudslides. NHC gave 93L a 30% chance of developing into a tropical depression by Friday morning in their 8am outlook; I'd put these odds at 50% now, given the continued increase in organization seen on satellite images.

Elsewhere in the tropics
A tropical wave near 14°N 34°W, about 500 miles west-southwest of the Cape Verde Islands off the coast of Africa, is moving westward near 15 - 20 mph. This wave has little heavy thunderstorm activity associated with it due to dry air, but an impressive amount of large-scale spin is obvious in visible satellite loops. This wave is expected to arrive in the Lesser Antilles Islands by Saturday. Three of our four reliable models for predicting tropical storm genesis predict that this wave could develop into a tropical depression sometime Friday through Sunday. A west-northwest track through the Northeast Caribbean bringing the storm near Puerto Rico by Sunday or Monday is favored by most of the models.

Harvey, if 93L makes it, will just add to the record of weakness for this season. 8th tropical storm, I can't believe it.

Hopefully 97L will break this absurd chain of tiny storms that barely deserve a name.




doesn't surprise me at all....i dont even expect major development until august 15th on. it's not out of the realm of possibilities to get a large cane in the atlantic region w/ a deep drop in millibars before august 15th, but it usually doesn't happen. however we are moving through the alphabet relatively fast compared to say, 2004 katrina (k) 8/25.

Heat watch: Today may be August’s hottest

Please, make it stop.

Houston hit 103 degrees Wednesday and it could get hotter today.

So far this summer, and alas it’s far from over, College Station, Huntsville, Conroe and Houston’s Hobby Airport have all beaten the record for the most 100-degree days in 1980.

Bush Intercontinental, Houston’s official weather site, now has just four to break its record as well.

Of course we’ve already set the record for most 100-degree days in a row, with 17 and counting, breaking a streak of 14 recorded in 1980

At least we’re not going to set a record high temperature for today, as it doesn’t look like we’ll get to 108 degrees, which the city recorded in 1909. Interestingly that’s just 1 degree below the warmest temperature ever measured in Houston, 109 degrees, reached Sept. 4, 2000.

I remember that brutal first week of September 11 years ago, do you?

FORECAST

The high pressure ridge remains in place, and should be strongest today before beginning to slightly weaken Friday, according to the National Weather Service. This slight weakening could open the door to showers Friday, but expect them to be isolated.

Other than that it’s business as usual, with today probably reaching 103 to 105 degrees, and highs across most areas in Houston north of downtown reaching 100 through the early part of next week.

Record drought at root of area trees' deaths

Texas' historic drought is taking a toll on trees in parks and other public spaces, a problem complicated by restrictions on outdoor water use imposed by Houston-area cities.

In Galveston, which banned outdoor watering last week but relaxed the restrictions this week, officials are struggling to protect 8,000 trees planted to replace those killed by Hurricane Ike in 2008. A company hired to plant and maintain the trees is using non-drinkable water to irrigate them.

In Houston, hundreds of trees in Memorial Park and other city parks have perished.

Galveston officials on Tuesday loosened the city's ban on outdoor watering to allow residents to water landscaped areas before 10 a.m. and after 8 p.m. on designated days. The decision came after the Texas Commission on Environmental Quality rescinded its Aug. 11 mandate to eliminate all outdoor lawn and landscape watering in cities that draw water from the Brazos River Basin.

Hey NOLA... I gotta admit, if I'm gonna have a streak of 7-8 in a row before Aug 21, I'd rather it be the TSes than the hurricanes, like the EPac is doing. 7 hurricanes in a row is cool for the EPac, because with this setup they're almost certain to go out to sea. If we'd have gotten those 7, we'd have had multiple massive landfalls - all before the height of the season!

It is not JFV, I no what handle JVF is using here so please stop always thinking a new handle is JVF, even the ones stating they are JFV, like JFV2015. That is an imposter. We here have made JFV famous. The less we talk about him the less people will try to pose as him.

Although 93L looks better on satellite, for some reason CIMSS vorticity analysis is not that impressive, and show 93L isn't even stacked well at this time.

agreed :) texas needs it bad, but what y'all really need is slow drizzle enough to let the soil moisten up so there is retention possibility. otherwise big rain fast is gonna flood like las vegas w/o washouts.

93L looks like its going to straight to Harvey and skip the TD status, although anyone else see the outflow he produced protruding to his north and west? Might be some dry air issues still.
