The orange-colored area below has the most potential to become our next
named storm… EMILY.

A WELL-DEFINED LOW PRESSURE SYSTEM ASSOCIATED WITH A TROPICAL
WAVE IS LOCATED ABOUT 1100 MILES EAST-SOUTHEAST OF THE LESSER
ANTILLES.

WHILE THIS SYSTEM IS CURRENTLY PRODUCING ONLY LIMITED SHOWER
AND THUNDERSTORM ACTIVITY… ENVIRONMENTAL CONDITIONS APPEAR
FAVORABLE FOR GRADUAL DEVELOPMENT OVER THE NEXT COUPLE OF
DAYS. THIS SYSTEM HAS A MEDIUM CHANCE… 50 PERCENT…OF BECOMING
A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES WESTWARD
OR WEST-NORTHWESTWARD AT 15 TO 20 MPH.

TROPICAL STORM DON DISCUSSION NUMBER   1
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL042011
400 PM CDT WED JUL 27 2011

AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT INVESTIGATING THE
TROPICAL WAVE OVER THE SOUTHERN GULF OF MEXICO FOUND A CLOSED
SURFACE CIRCULATION WITH A CENTRAL PRESSURE OF 1001 MB.  THE
MAXIMUM 1000 FT FLIGHT-LEVEL WINDS WERE 45 KT EAST OF THE CENTER...
AND THERE WERE SEVERAL RELIABLE-LOOKING SMFR SURFACE WIND ESTIMATES
OF 35 KT.  BASED ON THIS...THE SYSTEM IS DESIGNATED AS TROPICAL
STORM DON.  THE AIRCRAFT DATA SHOW THAT THE CIRCULATION CENTER IS
ELONGATED...AND IT IS POSSIBLE SOME REFORMATION OF THE CENTER COULD
OCCUR TONIGHT IN RESPONSE TO CONVECTIVE BURSTS.

THE INITIAL MOTION IS A SOMEWHAT UNCERTAIN 295/10.  DON IS SOUTH OF
A LOW/MID-LEVEL RIDGE OVER THE NORTHERN GULF OF MEXICO...AND WATER
VAPOR IMAGERY SHOWS UPPER-LEVEL EASTERLY FLOW DEVELOPING TO THE
NORTH AND NORTHEAST OF THE STORM.  THE LARGE-SCALE MODELS FORECAST
THAT WITHIN 24 HR DON WILL BECOME EMBEDDED IN DEEP-LAYER EASTERLY
TO SOUTHEASTERLY FLOW THAT SHOULD PERSIST FOR SEVERAL DAYS.  THIS
EVOLUTION SHOULD STEER THE STORM GENERALLY NORTHWESTWARD.  WHILE
THE MODELS AGREE WITH THIS SCENARIO...THERE IS A SPREAD IN THE
GUIDANCE ON WHERE DON WILL REACH THE NORTHWESTERN GULF COAST.  THE
GFDL AND GFS ARE FARTHEST TO THE RIGHT...CLOSER TO THE HOUSTON/
GALVESTON AREA.  THE UKMET/ECMWF ARE FARTHEST TO THE LEFT...CLOSER
TO THE BROWNSVILLE AREA.  THE FORECAST TRACK LIES BETWEEN THESE
EXTREMES AND IS CLOSE TO THE VARIOUS CONSENSUS MODELS.

DON IS OVER THE WARM WATERS OF THE GULF OF MEXICO...AND THE
GLOBAL MODELS FOR THE MOST PART FORECAST LIGHT TO MODERATE
VERTICAL WIND SHEAR OVER THE SYSTEM FOR THE NEXT 72 HR.  DESPITE
THIS...NONE OF THOSE MODELS SUGGEST SIGNIFICANT STRENGTHENING OF
THE STORM...AND NEITHER DOES THE GFDL.  THE SHIPS...LGEM...AND HWRF
MODELS FORECAST THE SYSTEM TO REACH 55-65 KT BEFORE LANDFALL IN
TEXAS...AND THE INTENSITY FORECAST FOLLOWS THAT SCENARIO IN BEST
AGREEMENT WITH THE SHIPS MODEL.  IT SHOULD BE NOTED THAT THE 48 HR
INTENSITY OF 55 KT IS WELL BEFORE LANDFALL...AND DON COULD GET
STRONGER THAN THIS BETWEEN 48-72 HR.

WATCHES AND/OR WARNINGS WILL LIKELY BE REQUIRED FOR PORTIONS OF THE
TEXAS COAST TONIGHT OR THURSDAY.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT WED JUL 27 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A TROPICAL WAVE OVER THE
NORTHWESTERN CARIBBEAN SEA JUST TO THE SOUTH OF THE WESTERN TIP OF
CUBA HAVE BECOME BETTER ORGANIZED OVER THE PAST FEW HOURS...AND
SURFACE OBSERVATIONS SUGGEST THAT A CIRCULATION COULD BE FORMING
ABOUT 125 MILES EAST OF CANCUN MEXICO.  IF THESE TRENDS CONTINUE...
A TROPICAL DEPRESSION COULD DEVELOP LATER TODAY.  INTERESTS IN THE
NORTHEASTERN YUCATAN PENINSULA SHOULD MONITOR THE PROGRESS OF THIS
SYSTEM AS IT MOVES WEST-NORTHWESTWARD NEAR 15 MPH.  THIS SYSTEM HAS
A HIGH CHANCE...70 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

The answer, Greatly. Two weeks ago, Southeast Alabama (the entire WTVY area) was under D5 drought conditions: Exceptional Drought. While we are not cleared of the drought completely…All of the WTVY viewing area and almost all of the Southeast is no longer in the most serious drought conditions. However, much of the Panhandle and SW Georgia are still under extreme Drought, or D4 conditions while Southeast Alabama is under D3: severe.

It is a little late to save much of the Summer crops quality, but the rain we are getting now is coming in increments, which is perfect for Fall crop development.

This  blog was an experiment done by Meteorologist Mark Holley at WEAU in northern Wisconsin, one of the 20+ states that has been affected by the nation’s heatwave. Northern Wisconsin? Yes! A place that saw -20 degree winter temps had highs up to 105 and heat indexes into the 115 degree range earlier this week!
 
160 Degrees inside at 10:30 AM
These images had to use a meat thermometer to record the heat because normal thermometers stop at 120 degrees. The car was not on and the cookies placed in the back window.
 
Heated tp 180 degrees and stayed for 3 hours!

After four hours the cookies were basically completely baked.

 
This demonstration is why you should NEVER leave a pet or child in a vehicle unattended. A car can hit 120 degrees in 20 minutes with the widows closed. This very easily can kill a pet or child!!!

 

  So….you thought it was a bad summer across the Southeast? While it is true that we have had our share of heat advisories and humidity this summer, we are far from alone. The highest heat inAlabamaoccurred in late June/early July, but now it plagues the middle of the nation.

How do people in Chicago and northern Wisconsin handle this when a mere 5 months ago were facing sub-zero wind chills?

 The culprit for this is a summertime phenomenon is an expansive area of high pressure, called a sub-tropical high. A subtropical high is a semi-permanent weather fixture. This means it can stay in one place for several weeks at a time. When the polar jet stream retreats to the north, theGulf of Mexicocan extend its influence further north than simply the gulf coast states.

The area of high pressure acts to suppress rising motion, which is needed to develop storms. This as a result keeps all the hot and humid air, exactly that…hot and humid.

This is how states as far north as the Canadian boarder end up with Heat Index values well into the triple digits.

So just how bad is it this week across the country? Here are some stats: 17 States, primarily in theMidwestare under Excessive Heat Warnings. 18 States have portions under Heat Advisories.  Over 40 states will reach the 90’s today and close to twenty could reach triple digit actual temperatures. This is the tenth day of the current heat wave.

For a “refreshing” change, the only part of Alabama under any form of heat warning is the extreme north. Our highs will not hit triple digits, and heat index values should also remain below 100 today.

So while you feel like you may be melting, just think about those who are used to shoveling for 5 months out of the year, and how they may be handling the heat….

Arizona was hit by its second giant dust storm in two weeks yesterday, turning the sky brown, delaying flights and causing mayhem for motorists.

The dust storm, known as a haboob, formed in Pinal County and headed north-east, engulfing Phoenix at about 5:30 pm.

The monster dust wall was about 3,000 feet high and created winds of 25 to 30 mph, with gusts of up to 40 mph.

The death of a comet that plunged into the sun was captured on camera this month for the first time in history, scientists say. 

The comet met its fiery demise on July 6 when it zoomed in from behind the sun and melted into oblivion as it crashed into the star.

It was NASA’s Solar Dynamics Observatory (SDO), a satellite orbiting Earth that studies the sun, which witnessed the comet’s death-blow.

One of the SDO spacecraft’s high-definition imagers “actually spotted a sun-grazing comet as it disintegrated over about a 15 minute period (July 6, 2011), something never observed before,” SDO officials said.

Comets have been spotted near the sun before, but last week’s object was the first to be observed in real-time as it disappeared.

“Given the intense heat and radiation, the comet simply evaporated away completely,” SDO officials said.

The comet was a type known to astronomers as a sun-grazing comet because its path brought it extremely close to the sun.
