The hurricane season of 2007 is almost over (again!) Tropical Storm Olga's passage over the rough terrain of Hispaniola has considerably disrupted the circulation of the storm, and visible satellite loops show a poorly organized circulation with a few weak rain bands removed to the north and east of the center. Radar loops out of Gran Piedra, Cuba show disorganized patches of rain impacting eastern Cuba, western Haiti, and the southeastern Bahama Islands. Puerto Rico took the brunt of Olga's rains, with amounts exceeding eight inches common (Figure 1). Satellite estimates of rainfall over Hispaniola show maximum rainfall amounts of up to four inches thus far over the northern Dominican Republic and Haiti. Additional rains of 2-4 inches from Olga may cause localized flash flooding and mudslides, but Olga will cause nowhere near the chaos that the 10-25 inches of rain from Tropical Storm Noel did in late October.
Wind shear has increased to 30 knots over Olga, and water vapor satellite imagery shows that Olga is moving into some very dry air. These influences should destroy Olga by Thursday. The remnants of Olga may still bring heavy rains of 2-4 inches to the southeast Bahamas and eastern Cuba, and 1-2 inches to Jamaica and the Cayman Islands. The 00Z runs of the GFDL and HWRF computer models foresee that Olga will regenerate on Friday and threaten the north coast of Honduras on Sunday as a Category 1 hurricane, but this solution is not supported by the other models. Given Olga's current weak condition, it is unlikely there will be enough left of the storm on Friday to regenerate into anything.

Major 'Noreaster coming Sunday
All of the major computer models forecast that a major winter storm will track across the Ohio Valley on Saturday, then explode into a powerful 'Noreaster Sunday off the U.S. northeast coast. Heavy snow amounts of 1-2 feet and significant ice accumulations are possible in inland regions of the Northeast. Rain appears to be the most likely type of precipitation at locations nearer the coast, such as Philadelphia, New York City, and Boston. It is too early to be confident of this forecast, since minor changes in the storm's track will greatly influence the type of precipitation. Minor to moderate coastal flooding is possible along the coast from New York City to Maine on Sunday.
Ice storm in the Midwest
I haven't found the opportunity to say much about the remarkable ice storm that has paralyzed much of Oklahoma, Kansas, Missouri, and surrounding regions this week, as I've been busy talking about Olga and trying to keep up on the latest in climate change science at the American Geophysical Union Conference here in San Francisco. The wunderphotos posted by people to the web site have been truly astounding, chilling, and beautiful, and I thank all of you who posted photos.
I'll have a update Thursday morning.

Broward County here...
about 75 degrees now.. everyday it is getting into low 80's... our next cool down will be Sun/Mon highs in 70's LOL
we have been getting some off and on showers.
I see we are still watching TD Olga and the big snow/ice storm!!!
The reason I like the NAM is the double Low it developes. Parent Low heading tword the Lakes with a coastal Low developing off Delmarv heading south of LI the to the Cape.
GFS sort of hints at this but keeps the main vorticy as a single Low heading off the Virgina Capes and to the 40/70.
The remnant low......Olga.......still looks impressive for a remnant low....The shear that has been talked about.......I see in some areas. Kind of hard to find being the heights of the showers are not that high. There is some areas showing evidence of shear and some not......Just off the northern cuba coast, those storms dont have much shear while east of Olga near Hispanola shows the shear. This is a unique situation and has been. Still some low topped convection firing around the center.
Experience tells me that as long as I see a circulation then there is still a chance of re-generation............
sleet right now 10:09am
I am at work so its probably snow at my house
thanks
Nothing is fair in the NE except northern Maine.
LOL NE check your local sation? is it set for Maine LOL
Have ice pellets the size of BBs and ball bearings falling heavy.
WU better get onboard LOL
ice pellets coming down hard now. Size is still growing.
There are no west winds to speak of in the cayman islands and pressures of 1012 to 1013.
skies are overcast, but the clouds are mid-to upper, not low,
the wind is light...and for once it's not snowing!
Give us an hour or two. LOL!
So obviously..we liked the West wind...best.
There used to be a Cookie Factory, in the West..and when the West wind blew..it felt as though, we ..were..blessed.
