After a wild spring season that featured the 2nd coldest April and warmest May on record since 1981, summer 2018 is shaping up to be warmer than normal across most of the country, though not quite as hot as in some recent years. Because the last decade has seen some sweltering summers, the average summer temperature over the previous ten years is much warmer than the 30-year normal. Note also that the higher population areas of the East and West Coasts, as well as all of the southern US, have trended warmer while the lower population areas of the north-central US have seen little to no warming trend. So, not only have summers been trending warmer, but that warming trend has primarily been focused on the higher population areas of the country.Topics: Heat | Frontier |
The heat has been on across much of the US with the hottest area making a bullseye in the center of the country. Over Memorial Day weekend, high temperatures soared into the upper 90s and low 100s …temperatures that hot haven’t been seen in May since the 1930s! Below are just a few locations that experienced one of the hottest Memorial Day weekends on record:Topics: Heat | Frontier |
After a very cold month of April, the pattern has turned markedly warmer during May. While that has generated above-normal cooling demand as portions of the country reach the 90s and portions of the Southwest even reach the 100s, much of the Midwest and Northeast is finally seeing some pleasant weather. There is still usually some heating demand across the northern US in early May, but the warmer weather this month has limited that.
Tonight, the Los Angeles Dodgers will play their first World Series in nearly 30 years when they take on the Houston Astros, who themselves haven’t played in the Fall Classic in 12 years. With the difference of three decades between the two World Series playoffs for the Dodgers, how different will the weather be? Both Game 1 in 1988 and 2017 will be played at Dodger Stadium in Los Angeles so let’s look at the weather for these games.Topics: WeatherOps | Heat |
Heat waves are often underestimated weather hazards in terms of safety and damage to both sensitive crops and manmade constructs. Kinks in the jet stream, often called omega blocking or cut-off Highs, periodically allow for heat to flow poleward and linger potentially for days or weeks. High pressure regions and their subsidization of cool air aloft cap the typical vertical transfer of heat from sunbaked surfaces. The air warms through compression while descending and gets hot before reaching the surface. The two sources work together to heat a region like a moving oven.
One of the most common terms we hear during the summer when discussing the weather is Heat Index. While the Heat Index can give you an idea of how dangerous the heat can be, there is another lesser known variable that may give a complete description, known as the Wet Bulb Globe Temperature.Topics: Heat |
July and August are well known for extreme temperatures in many parts of the U.S. The central part of the country is currently experiencing the summer heat full on right now. The temperatures may not seem high, but as the saying goes, "it's not the heat, it's the humidity."Topics: Heat | Drought |
