Although we are heading back into 90 degree weather over the next several days, there is some relief in sight by Sunday afternoon.  The GFS model panel above is valid at 1pm Sunday.  It forecasts a cold front (drawn in blue) to be well east of us by then, with another strong high pressure center dropping out of Canada (a lot like the last one).  This could mean more highs in the 70sto near 80 with overnight lows in the 50s Sunday through Tuesday.

Expect scattered t’shower chances to pick up Friday through  Sunday morning before drying out behind the front.

By the way, read below about newly formed Tropical Storm Danny.

As we have been anticipating, Tropical Storm Danny has formed in the Atlantic about 775 south southeast of Cape Hatteras, North Carolina.  The track brings it close to Cape Hatteras as a Category 1 Hurricane, before following Bill’s path just offshore of New England by Sunday.  For the northeast it’s Yogi Berra’s “deja-vu all over again” for this weekend!

As Justin mentioned below, temps are finally getting back to normal or a little above.  Our normal high is 87, and we are forecasting 89 today, and 91 tomorrow.  There is only a very slim chance for a shower today in our southern and eastern counties.  Scattered rain chances increase somewhat later this week ahead of a cold front.  The latest model run shows another shot of cool and dry air (for the end of August) moving in by Sunday and hanging around on Monday, as well.  More relief from the heat and humidity would be nice.

Meanwhile, check out the disturbance north of Puerto Rico.  This will likely become Tropical Storm “Danny” in the near future.  A hurricane hunter plane is investigating this afternoon.  This system may parallel the east coast, possibly brushing the Outer Banks of North Carolina, and once again, Cape Cod.   Let’s hope it does stay offshore.  Here is the latest statement from the Hurricane Center:

TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT TUE AUG 25 2009

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

AN AREA OF DISTURBED WEATHER ASSOCIATED WITH A TROUGH OF LOW
PRESSURE INTERACTING WITH AN UPPER-LEVEL LOW IS CENTERED ABOUT
325 MILES NORTH-NORTHEAST OF SAN JUAN PUERTO RICO.  THIS SYSTEM
CONTINUES TO SHOW SOME SIGNS OF ORGANIZATION…AND UPPER-LEVEL
WINDS ARE FORECAST TO BECOME MORE CONDUCIVE FOR DEVELOPMENT
DURING THE NEXT DAY OR SO AS THE SYSTEM MOVES WEST-NORTHWESTWARD
AROUND 20 MPH.  THERE IS A HIGH CHANCE…GREATER THAN 50
PERCENT…OF THIS SYSTEM BECOMING A TROPICAL DEPRESSION OR TROPICAL
STORM DURING THE NEXT 48 HOURS.  A RECONNAISSANCE AIRCRAFT IS
SCHEDULED TO INVESTIGATE THE AREA LATER THIS AFTERNOON.  INTERESTS
IN THE BAHAMAS SHOULD MONITOR THE PROGRESS OF THIS SYSTEM.

THE BROAD AREA OF LOW PRESSURE LOCATED OVER THE SOUTHWESTERN
CARIBBEAN SEA THIS MORNING HAS MOVED INLAND OVER CENTRAL AMERICA. 
THIS SYSTEM IS EXPECTED TO PRODUCE LOCALLY HEAVY RAINFALL OVER
PORTIONS OF CENTRAL AMERICA DURING THE NEXT DAY OR SO AS IT MOVES
WESTWARD INTO THE EASTERN PACIFIC OCEAN.

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

After a comfortable start Tuesday morning (see entry below), temps will warm into the upper 80s by the afternoon hours.  The humidity will start to slowly creep back up on the heals of a light southeasterly breeze.  There might be a few showers in our east and southeastern counties by afternoon (20% chance) in that southeast flow (see Predictor below).

If you click on the 7 Day Forecast to the right, you will see that scattered shower chances will increase during the later part of the week.  Long range GFS model forecast shows another front moving in Saturday afternoon to cool us down again Saturday evening through Sunday and Monday.  We will follow that as the week wears on.

Temperatures and humidity remained low for the month of August again today, with highs only in the low 80s on the hourly reports.  With clearing skies tonight, and low dew points, temps should once again fall to pleasantly cool levels, although they may be a few degrees up from this morning’s lows.

On Tuesday afternoon, temps will warm to the upper 80s.  An upper level low to our south may supply a shower or two to our east and southeastern counties.  Those chances there may run about 20%.

On Wednesday, we may touch 90 again.  As we head out in the 7 Day Forecast, we may see another shot of cooler air by Saturday night through Sunday and Monday.  We’ll keep you posted.
