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.
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.
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
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
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.
