PM Update: Spectacular weekend ahead

By Ian Livingston

A whole lot of clear skies in our near future

We've found ourselves back in a pleasant weather regime and it's not going anywhere anytime soon. Cool air aloft has promoted some cloudiness, but otherwise it's been pretty fantastic -- a theme of late. Temperatures have peaked in the upper 70s and lower 80s across the area during the day. Clouds will dwindle heading into evening and the stage is set for an awesome weekend.

Through Tonight: Any remnant clouds dissipate heading through the evening and into the night, leaving us mostly clear. Lows should reach the lower 50s in the coolest locations to near 60 downtown.

Tomorrow (Saturday): A perfect start to a perfect weekend? Looks that way to me. Mostly sunny skies and light winds rule the day as temperatures rise to highs near 80 or into the lower 80s.

Tropics: A slowly weakening Hurricane Karl made landfall in Mexico around 12:30 EDT with sustained winds of 115 mph. According to Weather Underground's Jeff Masters, Karl became the first major hurricane ever to impact the Bay of Campeche. Two others skirted the bay but were much further north. Karl was the fifth major hurricane of this season, which puts 2010 ahead of the pace for 2005 in that category through today.

As happens all too often in Mespmerica, the rains from Karl are ultimately going to be an even bigger problem than the wind.

At some point, the system could start picking up moisture from the Pacific Ocean (if it's not already doing so). Although the NHC five-day cone doesn't show Karl re-strenghtening in the Pacific, if Karl traverses Mexico fast enough, it could re-form.

But if Karl gets tangled up in the Sierra Madre Occidental, the currently predicted rainfall of up to 15" is optimistic.

The daily coop observer report shows a remarkable variety of high temperatures yesterday from 92 at National to 67 at Hagerstown, 66 at Keyser.

Question for Ian: the revised edition of "Great Blizzards and Snowstorms of Washington, D.C." scheduled to publish later this year, covers the winter of 2009-10, yes?

(For those of you who subscribe to "Weatherwise", this is mentioned on p. 43 of the September/October issue. Apparently there will be data "from every snow event from 1884" so it certainly sounds as if 2009-10 will be in the book.)

Jerry, Kevin and I have decided to postpone the larger book until next year so we can spend the time needed rather than rush. We will instead release a shorter book focusing on 2009-10 this fall that will also cover some information on other top storms as well as comparisons back to the other top winter. Ultimately the other book will cover the whole historical period.

Thanks, Ian, good to know.

That "Weatherwise" article makes the book that will eventually come out sound very worthwhile but given its scope, postpoining makes a lot of sense.

Meanwhile, I'm looking forward to the 2009-10 book (as I'm sure many others will, as they learn about it).

Breaking news ; )) Yesterday's tornado hit Joisey but not The City, ABC News is reporting. Guess it couldn't make it through the Holland Tunnel because of the rush hour traffic.

Also, re: my post above, looking at the satellite map of Karl, it's obvious the storm has begun interacting with the Pacific Ocean. My concern is the storm's rotation picking up copious moisture from the Pacific. Right now, it looks more like fringe outflow than actual rain bands that is swirling in from the Pacific.

The one downside to the cooler temps is I'm starting to find stink bugs in the house again.

Currently down to 59.4 after a high of 71.8 today...

Now the NWS is saying two tornadoes did touch down in NYC on Thursday. One fatality, trees hit badly, etc. One tornado hit Brooklyn; the other? Based on a NY Times interactive map, might have been Queens. I won't be up there until the end of the month, but planning to take the Acela, not the Tornado to NYC.
