The South Central Texas Weekend Weather And Tides Forecast - 7/8-10/2011

Day/Date: Friday, July 8, 2011 - Time: 7 AM CDT

The South Central Texas Weekend Weather Outlook

This weekend's weather will again be much like what we experienced last weekend. The daytime air temperatures, under mostly sunny to partly cloudy skies will be in the mid-90s inland with the lower-90s felt along coastal areas with Southerly breezes in the 6-12 knot range.
Nighttime weather conditions, under partly cloudy skies, will see air temperatures in the mid-70s inland with the upper-70s felt along coastal areas. The breezes will be out of the South and will stay in the 6-12 knot range.
Because this is the Summertime along the Gulf coast, don't forget the possibility of normal 'sea breeze' development each day during daytime hours. As the 'sea breeze' builds, the warm, humid air associated with it rises encountering cooler air aloft which increases the chance of a shower or thunderstorm, hail and gusty winds along coastal areas. It's possible for the effects of the 'sea breeze' to be felt as far as 10 miles inland.
However, keeping an eye on the sky should allow you to perform and enjoy any outside activity you may have planned so get out there and do your thing!

Gulf Of Mexico Marine Weather Forecast:

The maritime weather forecast today for the Gulf Of Mexico, out to 60 nautical miles, calls for S winds at 4-8 knots with seas of 1-2 ft. having a period of 7 seconds. Saturday, the winds will continue from a S direction with velocities in the 4-8 knot range with wave heights in the 1-2 ft. range having a period of 7 seconds. Sunday will see the winds shift slightly to a SE direction with velocities in the 6-12 knot range with wave heights of 2-3 ft. having a period of 6 seconds.
With the onset of warm weather along the Gulf coast comes the possibility of normal 'sea breeze' development each day during daytime hours. As the 'sea breeze' builds, the warm, humid air associated with it rises encountering cooler air aloft which increases the chance of a shower or thunderstorm, hail and gusty winds along coastal areas. It's possible for the effects of the 'sea breeze' to be felt as far as 10 miles inland.
A '1rst Quarter Moon' ("Neap Tide") occurs today Friday, July 8, 2011.
Tidal levels will be near normal today and will range between +1.2 and +1.7 ft. for the first set and at -0.1 ft. for the second tide - a low one.
They will remain near normal Saturday and Sunday, with Saturday's tide(s) ranging between +1.5 and +1.9 ft. and between -0.4 and +1.6 ft. for the second set. Sunday the tide(s) will range between +1.6 and +2.1 ft. for the first set and between -0.6 and +1.6 ft. for the second one.
The average tide is referenced from the 'Mean Lower or Low Water (MLLW)' figure.
The beach water temperature, as measured at the Galveston Island Pleasure Pier, is currently 87 degrees F.

High: AM - +1.6 Ft.
Low: PM - -0.6 Ft.

Galveston Bay/Trinity Bay Marine Weather Forecast:

The maritime weather forecast today for Galveston and Trinity Bays calls for S winds at 4-8 knots with the Bay water conditions smooth. Saturday, the winds will continue from a S direction with velocities in the 4-8 knot range with the Bay waters smooth. Sunday will see the winds remain from a S direction in the 4-8 knot range with the Bay waters smooth.
With the onset of warm weather along the Gulf coast comes the possibility of normal 'sea breeze' development each day during daytime hours. As the 'sea breeze' builds, the warm, humid air associated with it rises encountering cooler air aloft which increases the chance of a shower or thunderstorm, hail and gusty winds along coastal areas. It's possible for the effects of the 'sea breeze' to be felt as far as 10 miles inland.
A '1rst Quarter Moon' ("Neap Tide") occurs today Friday, July 8, 2011.
Tidal levels will be near normal today and will range between +0.6 and +0.7 ft. for the first tidal set and between -0.1 and +0.9 ft. for the second tidal set They will remain near normal Saturday and Sunday, with a tide of between -0.2 and +0.9 ft. on Saturday and between -0.4 and +0.9 ft. on Sunday for it's tidal set .
The average tide is referenced from the 'Mean Lower or Low Water (MLLW)' figure.
The Bay water temperature is currently measuring 88 degrees F.

WEATHER FACTS


Did You Know?....

1. How Hot Air Masses Are Formed
It may appear as if the Sun's rays heat the air directly, but that is not the case. Instead, short-wave radiation coming in from the Sun passes through the atmosphere and heats the ground. The heat then radiates from the ground and warms the air

2. A 'Bermuda High'!
The 'Bermuda High' is a large sub-tropical area of high pressure that sits over the Atlantic Ocean. It is most often found near the island of Bermuda, hence its name. During the Summer months, the high is very strong and often brings hot and humid weather to the eastern U.S. The 'Bermuda High' also has a profound impact on steering tropical systems in the Atlantic. The position of the high can mean the difference between a hurricane making a landfall along the Gulf Coast, East Coast, or steering out to sea

3. 'Dry Thunderstorms'!
'Dry thunderstorms' are a big problem, especially across the interior Western United States during the Summer. These thunderstorms do produce rainfall, but it evaporates before reaching the ground. Unfortunately, the lightning that is produced does strike the ground and can easily trigger small fires that can turn into major forest fires.

4. July Traits
The portion of the United States prone to severe thunderstorms with damaging winds and large hail tends to be farther North in July. The reason is that the Jet Stream (main contributor to damaging thunderstorms) is much farther North this time of year.

5. Pressure Difference Cools The Coast
Cool marine air inhabits the immediate coastline of California most of June, July and August. Here's why. The interior is very hot which creates a relative zone of low pressure. In contrast, cooler air over the ocean causes higher pressure. This pressure configuration causes a gentle push of cool marine air against the coastline. The temperature differences created by this effect are huge. In Los Angeles, it might be 70 degrees when at the same time Palm Springs is 105.

Discussion:

I continue to monitor the large area of disturbed weather covering the Northern Caribbean into the Eastern Gulf of Mexico across Florida into the Northern Bahamas. Surface data shows the surface pressure has not changed much during the past 24 hours over the Eastern Gulf of Mexico where I'm seeing some cyclonic turning in the cloud pattern. A North-South elongated area of low-pressure is roughly centered near Latitude 27 degrees North, Longitude 86 degrees West or roughly 213 miles South of Panama City, Fla. This feature appears to be slowly moving Northward.

Extensive showers and thunderstorms across Western Cuba and over the Yucatan Channel outlines an upper-level low-pressure trough. The weakly organized system will move inland over the Florida Panhandle tomorrow night, after which point the disturbed weather should move over the Southeastern U.S. Strong upper-level wind shear over this area created by a higher-level low, mostly around 40,000 feet over the Northwestern Gulf of Mexico, will continue to strongly discourage development.

A tropical wave moving over the Leeward Islands to along Latitude 65 degrees West is also experiencing strong upper-level wind shear from another high-level low located just Northwest of Puerto Rico. I'm seeing no important support for development with this tropical wave. Finally, there's a third system, a tropical wave, roughly between Latitude 45 to 50 degrees West, South of Latitude 15 degrees North. This feature remains disorganized and should start to affect the Windward Islands tomorrow. Long range computer models have backed off on the idea that this third system might support development over the Southern Caribbean or Southwestern Gulf of Mexico next week. The strong 'Bermuda High' pressure area will nose strongly into the Southeastern U.S. and Northern Gulf of Mexico during next week. This will force any potential development too close to land which will severely hamper it's development.

Stay tuned here for info on any new Atlantic Basin weather activity.


Please don't forget that when these tropical systems form - whether they remain a tropical depression or develop into a named tropical storm or Category ‘1’ through ‘5’ hurricane, each of these systems will ALWAYS BE A RAIN EVENT! When the term ‘hurricane’ is written or spoken, it’s human nature to think only of the wind speeds they contain but don’t overlook the fact that there is always torrential rainfall associated with any type of tropical system!

CoCoRaHS

The Community Collaborative Rain, Hail and Snow (CoCoRaHS) network is a grassroots network of volunteers who measure daily precipitation using a manual rain gauge (all volunteers must use the same style 4-inch plastic rain gauge).  Measurements are reported at 7:00 AM local time (2 1/2 hour window allows for flexibility) and are immediately available to the public on maps and in list format.  The data is used by several entities including NOAA's National Weather Service, NASA, and many more. …See More
