Dr. Jeff Masters' WunderBlog

A Tale of Two Invests
Posted by: Dr. Jeff Masters, 12:17 PM GMT on July 04, 2010 +2
Good morning, everybody, Dr. Rob Carver filling in for Jeff on Independence Day.

Currently, NHC is monitoring two different areas for possible tropical cyclone development. Invest 95L is about 125 miles west-southwest of the mouth of the Mississippi and it doesn't have much thunderstorm activity associated with it. Dry air from the north and strong wind shear have weakened it considerably from yesterday, and NHC believes it has a 10% chance of becoming a tropical cyclone before the feature makes landfall.

Invest 96L is in the western Caribbean sea and bears watching closely. Earlier in the morning, the convection was all on the east side of the circulation center, but thunderstorms have developed on the southwest side. According to the CIMMS wind shear analysis, 96L is on the outskirts of a low wind shear region just east of the Yucatan peninsula. It's also over warm SST's (>29 deg C), so it could intensify. NHC gives it a 20% chance of becoming a tropical cyclone in the next 48 hours. Computer models have 96L going through the Yucatan Channel then turning left and making landfall somewhere near the Rio Grande.

Next Update
My next post will be sometime Monday afternoon/evening. If the situation changes significantly before then, I'll make a new post. In any event, enjoy the holidays...

TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM EDT MON JUL 5 2010

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

SHOWERS AND THUNDERSTORMS REMAIN DISORGANIZED IN ASSOCIATION WITH A
SMALL AREA OF LOW PRESSURE LOCATED ABOUT 60 MILES SOUTHWEST OF
MORGAN CITY LOUISIANA. ENVIRONMENTAL CONDITIONS ARE NOT FAVORABLE
FOR DEVELOPMENT...AND THERE IS A LOW CHANCE...10 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE BEFORE IT MOVES INLAND BY
TONIGHT OR TUESDAY. THIS LOW IS EXPECTED TO MOVE NORTHWARD OR
NORTHWESTWARD AT 5 TO 10 MPH OVER THE NEXT DAY OR SO.

THE TROPICAL WAVE OVER THE NORTHWESTERN CARIBBEAN SEA HAS BECOME
LESS ORGANIZED OVERNIGHT AND THE RECONNAISSANCE AIRCRAFT SCHEDULED
FOR THIS AFTERNOON HAS BEEN CANCELED.
HOWEVER...ENVIRONMENTAL
CONDITIONS ARE CONDUCIVE FOR SOME DEVELOPMENT...AND A TROPICAL
DEPRESSION COULD STILL FORM OVER THE NEXT COUPLE OF DAYS AS THIS
SYSTEM MOVES NORTHWESTWARD AT 15 MPH. THERE IS A MEDIUM
CHANCE...40 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS. REGARDLESS OF DEVELOPMENT...LOCALLY
HEAVY RAINFALL AND GUSTY WINDS ARE POSSIBLE OVER THE CAYMAN
ISLANDS...THE YUCATAN PENINSULA...WESTERN CUBA AND THE NORTHWESTERN
CARIBBEAN SEA OVER THE NEXT DAY OR TWO.

A TROPICAL WAVE OVER THE FAR EASTERN CARIBBEAN SEA IS PRODUCING AN
AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS ACROSS THE LESSER
ANTILLES AND ADJACENT WATERS. UPPER-LEVEL WINDS ARE NOT FAVORABLE
FOR SIGNIFICANT DEVELOPMENT OF THIS SYSTEM AS IT MOVES
WEST-NORTHWESTWARD AT ABOUT 15 MPH OVER THE NEXT COUPLE OF DAYS.
THERE IS A LOW CHANCE...10 PERCENT...OF THIS SYSTEM BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS. REGARDLESS OF
DEVELOPMENT...LOCALLY HEAVY RAINFALL AND GUSTY WINDS ARE POSSIBLE
IN THE LESSER ANTILLES AND PUERTO RICO DURING THE NEXT COUPLE OF
DAYS.

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

The circulation is lower than yesterday. But 2 AM EDT central preassure is 1008mb so still low pressure. I think still danger system. Position and Shear are favorable to developed.

This rain is from the stationary front which resulted in 95L and the other yellow circle East of Florida.

I don't see Bonnie happening in the next 24-48 hours.

No way this season gets to 23...probably not 20.

Yeah, I know...it's only takes 1.

All of Florida has been getting pounded by rain the last few days... Not that we didn't need it, because the previous week or so was very dry. However, we don't need it back all at once.

I think there is a decent chance that 96L will turn into Bonnie by Wed/Thu in the Gulf...probably make landfall between Corpus / Lake Charles as a weak tropical storm.

Good Morning!

Thanks for the update nice job.

Still think center low preassure is about 1008mb or less. Last report was 1008mb at 2AM, i agree is less organized on SAT than yesterday, so vorticity is lower. Will see what happend in the next 2 days.

The same thing happened overnight to 92L. Some people said TD tomorrow, then it had a rough DMIN. It also need a surface circulation, just like 93L (again), to get better organized.

Just goes to show how unpredictable weather can be.
