There’s been no shortage of heat this summer and following a record hot June for the US, July started off tame with largely regionalised heat waves. However as the dryness expanding, so did the heat. Where dry, the heat has been running 2-4F above normal, particularly so in the Southeast and most recently the western […]
Published: Jul 20 2016 02:00 PM EDT By Jonathan Belles weather.com Sea surface temperatures so far this hurricane season have busted records in the Gulf of Mexico, running just under 2 degrees Fahrenheit above average, and that could mean more fuel for tropical storms and hurricanes if the season becomes more active. Temperatures at the […]
Relentless rainfall into the early part of the warm season makes for rapid crop growth. A lot of water is contained within both crop and soil beneath and when a powerful upper ridge develops, so the heat draws water vapour into the atmosphere increasing humidity. The below radar estimated rainfall for July so far indicates […]
Well what can I say, the majority of the Lower 48 is entering it’s first coast to coast heat wave since 2012 as a powerful, vertically stacked high pressure system spans coast to coast. How hot? Widespread upper 90s/low 100s for the Plains with a few 105-110s. How rare or unusual is this heat when looking back […]

Yesterday was cooler for the Northeast in the wake of the latest system while it was in the 100s as far north as South Dakota yesterday ahead of the next system. Current GFS 500mb height anomaly chart. Yesterday’s maximums. A large thunderstorm complex (likely an MCS) as blew up overnight bringing damaging wind, lightning and flooding rains, perhaps […]
