Ida’s Legacy: Historic Flood and Kansas-Size Tornadoes Paralyze Northeastern US

MN Drought Eases Slightly From Last WeekUS Drought Monitor Weather Extremes Trending More Extreme I’ve been tracking weather systems for 45 years, but nothing has prepared me for 2021’s dueling weather disasters. Our weather models have consistently underestimated the intensity of drought, fires and eastern floods. Why? Climate-warming greenhouse gases have doubled since preindustrial times, and these man-made gases are flavoring all weather now. Are too many people living in vulnerable areas? Yes. But Wednesday’s 1-in-500 year flooding from Philly to New York City and Texas-size tornadoes in New Jersey are more symptoms of our new reality. Flashes of Lukewarm....

Louisiana Left Reeling from “Ida” – Hurricane Strength Was No Surprise to Forecasters – Mandatory Fire Evacuations in Tahoe Basin

Paul Douglas Why September May Offer Year’s Best Weather ”September tries its best to have us forget summer” wrote English philosopher Bernard Williams. I love all the seasons (and the fact that Minnesota HAS 4 seasons) but September is my favorite month of the year. Days are still lukewarm, lakes warm enough for one or two more dips. Severe storms are rare as the noisy blur of summer fades into comfortable days with cotton-ball cumulus and low humidity. That is all fine and good but Minnesota is still too dry and dusty. According to the local DNR “As of this...

Querying for Historical Tropical Cyclone Data with the AerisWeather API

As Hurricane Henri approached the Northeastern US this past weekend, I wondered how often a tropical cyclone has come within 50 miles of New York City, Boston, or other cities. How many were hurricanes? To answer these questions, we can use the Tropical Cyclones Archive endpoint within the AerisWeather API. This endpoint provides access to the complete AerisWeather historical archive for tropical systems, with data from the late 1800s for the Atlantic basin and the mid-1900s for the Pacific basin. When using the tropical cyclones archive endpoint, we find that 21 tropical cyclones have tracked within 50 miles of New York...

Origin of “Dog Days” – Smoky US Summers On Increase Since 2016

Welcome to the Dog Days of Summer We get a whiff of Dog Days this week as daytime highs flirt with 90 degrees through Friday. Dog Days have nothing to do with an urge to pant or beg for treats, and everything to do with Sirius, the dog star – brightest in the nighttime sky. Ancient Greeks thought the star added to the heat of the sun, resulting in unbearable August heat. Of course it doesn’t quite work like that. Hazy, smoky sunshine lingers much of this week with thicker smoke the farther north and west you travel away from...

Adding Custom Styles to the Tropical Cyclone Module

With Tropical Storm Fred threatening the Gulf Coast states and peak hurricane season just around the corner, now is a great time to discuss how to take your hurricane tracking to the next level by adding custom styles to the Tropical Cyclone module on the AerisWeather JavaScript SDK. The AerisWeather JavaScript SDK has a plethora of features. The InteractiveMapApp allows you to plot weather data on an interactive map easily and comes with several built-in modules which can simplify the plotting of weather data. The Tropical Cyclone Module provides users with predefined styling and functionality for plotting various tropical cyclones endpoint-related data layers.  While these default styles may suffice for most...
