Humidity builds; Saturday thunder? Emily takes a nosedive

75 degree dew point at 6am Tuesday at MSP Airport

53 degree dew point at 1pm Wednesday

63 degree dew point at 10 am Thursday

After a 22 degree drop in dew point at MSP Airport in 30 hours, you can feel the humidity creeping back up again in Minnesota. Dew points are on the rise through the sticky 60s again, and may reach the tropical 70 degree point by Saturday.

Dew points in the upper 60s & 70s in Iowa are moving back north into Minnesota.

After record humidity this summer you have to wonder if moss is going to start growing on the trees. Is this the Twin Cities or Savannah?

Saturday storm chances:

As moisture increases Friday, a wave of low pressure will skirt the Minnesota-Canadian border Saturday. The system should spawn a few scattered T-Storms as it moves through the Dakotas Friday & Minnesota Saturday.

SPC paints slight risk for severe storms (in yellow) to the west Friday.

Emily fades over Hispaniola:

Once Tropical Storm Emily did a dissapearing act over Hispainola Thursday. The storm’s circualtion was never very strong, and it became even more disorganized as it interacted with the highly mountainous island.

Anatomy of a dying Tropical Storm:

Before: Emily looked somewhat better organized on Wednesday.

After: Emily’s interaction with mountainous terrain on Hispaniola tears the storm apart.

REMNANTS OF EMILY DISCUSSION NUMBER 13

NWS NATIONAL HURRICANE CENTER MIAMI FL AL052011

500 PM EDT THU AUG 04 2011

SINCE ITS INCEPTION…EMILY NEVER HAD A PARTICULARLY ROBUST

LOW-LEVEL CIRCULATION…AND THE HIGH TERRAIN OF HISPANIOLA

CONTRIBUTED SIGNIFICANTLY TO THE FURTHER DEGENERATION OF THE

CYCLONE TODAY.

SATELLITE…RECONNAISSANCE AIRCRAFT AND SURFACE

OBSERVATIONS INDICATE THAT EMILY NO LONGER HAS A CLOSED

CIRCULATION….AND THE SYSTEM HAS BEEN DOWNGRADED TO A TROUGH OF

LOW PRESSURE WITH ITS AXIS ALONG 75W. THIS WAS A BIG WIN FOR THE

ECMWF GLOBAL MODEL…WHICH NEVER DEVELOPED EMILY AND ALWAYS

FORECAST DISSIPATION NEAR HISPANIOLA.

THERE IS STILL A LARGE AREA OF ORGANIZED DISTURBED WEATHER OVER

HISPANIOLA ASSOCIATED WITH THE REMNANTS OF EMILY. THIS ACTIVITY IS

EXPECTED TO SPREAD TOWARD THE WEST-NORTHWEST AND NORTHWEST OVER

EASTERN CUBA AND THE SOUTHEASTERN BAHAMAS WITH SOME POTENTIAL

FOR REGENERATION IN THE NEXT DAY OR TWO.

EVEN THOUGH EMILY HAS DISSIPATED…HEAVY RAINS REMAIN A THREAT FOR

THE DOMINICAN REPUBLIC AND HAITI.

FORECAST POSITIONS AND MAX WINDS

INIT 04/2100Z 19.0N 75.0W 30 KT 35 MPH

12H 05/0600Z…DISSIPATED

Models track Emily’s remains near (over) Florida. The question is will she regenerate?

It remains to be seen if Emily’s remains will reorganize as it moves into the Bahamas. For now, the NHC has dropped the advisories for Emily. Emily has already thrown a few curve balls; let’s see if she has any more surprises up her sleeve in the coming days.
