We're suffering from a near-fatal case of boring August weather, and it's just awful.

This water vapor imagery from GOES East shows moisture (and a lack thereof) over the central and eastern Atlantic. Any disturbance that manages to get its act together over the next couple of days has to deal with the slug of dry air to the west. The summer doldrums continue...

How Does Summer 2014 Stack Up Against Previous Years?

Dennis Mersereau · 08/15/14 01:39PM

For those of us who live along the East Coast, this has been a pretty nice summer. With constant shots of cool air and low humidity filtering in from the north (thanks, Canucks!), temperatures are staying right around normal. The West, on the other hand, is baking. How does this summer compare to summers past?

Lightning Destroyed the Zephyrometer in a Fireball Yesterday

The New Zealand capital's famed Zephyrometer, a weathery sculpture that stands a little over 100 feet tall, met its demise after a thunderstorm struck Wellington on Thursday and a bolt of lightning destroyed the sculpture in a fireball, hurling its fiery remains onto the street below.

Greetings! I'm taking a mental health day today, so The Vane will be quiet until late tonight or tomorrow. The tropical Atlantic is quiet, there's only a small patch of severe weather over Idaho and Montana, and parts of the mountain west are on watch for flash flooding. Typical August day. Enjoy the lower humidity.

Trust No Bank (Thermometer)

Dennis Mersereau · 08/13/14 01:36PM

You're driving down the road on a warm summer afternoon. You pass your local bank and the display says it's 97°F. "Good grief," you think, "I didn't realize it was that hot." Well, it's probably not that hot. The thermometers they use at businesses with electronic displays are useless junk.

NOAA's Ark: Half a Foot of Rain Leaves Baltimore and Detroit Flooded

Major flooding is ongoing near Baltimore this afternoon after areas south of town have seen more than seven inches of rain in a short period of time, and amounts could approach ten inches before the storms stop. A similar situation unfolded in Detroit last night.

Meteorologists Did an Incredible Job Forecasting Hurricane Iselle

Dennis Mersereau · 08/11/14 02:52PM

Forecasters did a great job predicting the track of Hurricane Iselle as it headed towards Hawaii last week. Even almost a week out when the storm was a thousand miles from the Big Island, meteorologists had the hurricane's track pegged to within 30 miles of where it made landfall.

Hey, remember that forecast for a complete washout in the North Carolina Piedmont this weekend, with up to 7 inches of rain falling in some spots? Both the forecasters and the models were wrong. Really wrong. It rained everywhere except for in the Piedmont. Oops!

Iselle Makes Landfall in Hawaii, Julio Should Miss to the North

Dennis Mersereau · 08/08/14 05:58PM

Hurricane Iselle fell apart in a spectacular manner after making landfall on the Big Island last night weakening from a hurricane last night to a 50 MPH tropical storm this afternoon. The storm is now south of Oahu and falling apart quickly.

What Is the Difference Between a Cyclone, Typhoon, and Hurricane?

Dennis Mersereau · 08/07/14 03:43PM

One of the biggest sticking points when it comes to weather forecasts is the public's confusion over the terms "hurricane," "typhoon," and "cyclone." Since they're three different names, people think they're three different kinds of storm. Here's a quick explainer on what's in a name.

Hawaii Braces for a Direct Strike from Hurricane Iselle

Dennis Mersereau · 08/07/14 01:26PM

Hurricane Iselle is closing in on the Big Island this morning as the 80 MPH hurricane rapidly closes in on Hawaii. The entire state, home to nearly one-and-a-half million people, will see life-threatening weather conditions as the hurricane moves through over the next 24 to 36 hours.
