List of Record Hot Summer Cities – Tropics Heat Up – Science Behind Storm Surges and Atmospheric Rivers

Volatile Mid-Month Pattern? I’m seeing a few models with a large closed (“cut-off”) low over the nation’s midsection by mid-September, and confidence levels are low that the pattern envisioned by the GFS model (above) will actually verify. One things is certain: near-record heat will continue to bake much of the southern USA for much of September. Briefing: Issued Tuesday, September 1st, 2020: Atlantic Heating Up Again: Tropical Depression Fifteen. Fifteen formed late yesterday afternoon off the Southeastern United States coast and is sitting about 100 miles southeast of Cape Hatteras this morning (as of 5 AM ET). The good news...

Crazy Extremes Facing Denver – Did Harsh NWS Language Save Lives with “Laura”?

  Moderately Cool Third Week of September. Temperatures over the northern tier of the USA will be cooler than average 2 weeks out, if you buy the GFS solution above. We’ll see more warm fronts, more 70s and 80s into late September, but while much of the south and west sizzles Minnesotans will be reaching for sweatshirts much of the next 2 weeks. Definition of a Cold Front. I’m sure this has happened before, but I can’t remember anything quite this drastic in recent years; a nearly 65 degree drop in the span of 2-3 days? ECMWF (above) for Denver...

Dangerous Hurricane Laura Approaches Gulf Coast – Higher Resolution Tornado Simulations

Hurricane Laura Threatens Gulf Coast “The first rule of hurricane coverage is that every broadcast must begin with palm trees bending in the wind” wrote author Carl Hiaasen. True. And frantic TV reporters hunkered down on the beach. Hurricane Laura is forecast to come ashore late tonight, perilously close to Houston. The storm is passing over warm water, jet fuel for hurricanes. It may roar ashore with 115 mph winds and a basketball-hoop-high storm surge of over 10 feet. You can’t blame Houstonians for being paranoid. 3 years ago “Harvey” dropped 60 inches of rain, leaving behind $125 billion in...

Tracking “Omar” and “Nana” – Will We Run Out of Hurricane Names in 2020?

Like climate change, coronavirus often doesn’t hit home until it…hits home. One of my nieces at a big eastern university caught Covid-19 (she’s fine). My 91 year old mother-in-law, Josephine, also caught the virus and recovered. Her grandkids call her “Nana”, which is ironic. So far this year in the Atlantic we’ve had a Tropical Storm Josephine and a Tropical Storm Nana. 65-70 percent of hurricane season is ahead of us, with only 6 names remaining on the list. At this rate we may have to start over with the Greek alphabet. The last time that happened was 2005, the...
