Once again, it was the Weather Channel taking charge for the years hottest month. This was no fluke, July, as there were a lot of forecasts to contend with, much more than are typical, and the Atlantans showed the world a thing or too about their forecasting prowess. It’s not just web sites in Beta and Stephanie Abrams over there. They have been forecasting like it’s their job this year.
There’s an age-old myth that tornadoes don’t strike urban areas, and for the most part it’s pretty true. When you take into account the relative size of an urban area, or the downtown area of a major city more specifically, it pales in comparison to the amount of area around it. The downtown area of a city might encompass 2-8 square miles, meanwhile everywhere within a 1 hour drive, say a 75mile radius, covers over 17,500 square miles. Also since tornadoes are usually very small, you can see the tiny percentage an urban area might cover. However, just because it’s tough for Mother Nature to take aim, doesn’t mean it doesn’t happen. Minneapolis had a brief tornado roll through the downtown area just last summer. A couple days ago Fargo, ND saw a tornado hit the north side of town briefly in the middle of the night. On Sunday evening, a line of thunderstorms rolled through the New York City area and a confirmed tornado was sighted in the Bronx and rolled along for a little over half a mile, injuring 7 but thankfully no loss of life. What urban area will be the next on the list? Looks like the Dakotas are under the gun today, we’re looking at you Pierre!
We will still have to wait to see what a tropical storm or hurricane will do to the Gulf oil spill. Tropical Storm Bonnie developed over the Bahamas before making landfall in Miami-Dade county in Florida. It moved quickly over the Florida Peninsula, almost entirely unnoticed by most Floridians. It was simply a rainy system that brought a little bit of rain to south Florida and ALMOST knocked Jim Cantore’s hat off.
The fear, then, was that it would track over the oil spill, intensifying the whole to once again become a tropical storm before crashing into New Orleans. It was going to be interesting to see how such a system would affect the slick.
Well, that never happened. Bonnie moved through Florida very quickly, which was part of the reason it’s mark there was so mitigated. She continues to move quickly, which is preventing her from accumulating energy. Additionally, an unfavorable shear environment aloft is hampering the further strengthening of the system, even though Bonnie is over the warm Gulf waters. The result is that the system is now not expected to strengthen much beyond it’s current state. Winds are about 30mph, which isn’t an uncommon wind speed over the Gulf of Mexico even without a tropical system to contend with.
This is a huge break for residents of the Gulf of Mexico. Bonnie will merely be an inconvenience, rather than a disaster.
Shortly after Anthony posted the forecast for Atlanta (apologies for the delay.. some server issues beset us last night), I took this screen capture with a very impressive, very blue side bar ad.
Thanks Google, I’m sure most readers of this site are unaware of The Weather Channel. That said, with the way they have been forecasting this year, the whole site could pretty much be described as an ad for TWC.
The above image is the current SPC forecast for severe winds today. For forecasting an individual type of severe weather, seeing the 60% is extraordinarily rare. When the SPC puts out such outlooks, they generally expect SOMETHING to happen, even when there is only a 15% chance, for example, of severe weather, because technically those percentages are for the chance that one of those events happens within 25 miles of a point in the outlined area. The suggestion of that 60% area isn’t so much that damaging winds are more likely or will be stronger, it’s simply that the damaging winds are almost certain to be widespread.
Later this afternoon, Anthony will come through and post a radar still to see how the storms are doing after what is certain to be a derecho sets itself up in eastern Minnesota or western Wisconsin. Later, I’ll come back and update with an image of the storm reports of the day. Stay tuned and keep safe.
UPDATE (5:16PM CDT): Well our line of thunderstorms developed nearly right on top of the Minneapolis-Twin Cities metro area earlier this afternoon, with a confirmed tornado not too far south-southeast of the area. Now as the line heads towards the east, it’s starting to transition to a severe thunderstorm threat, albeit with some embedded tornadoes possible. And later tonight, another possible line of thunderstorms as the front itself moves through the region. Active day around here for sure.
We can now take a look at the storm reports so far today to see how things have gone. They are widespread across northern Wisconsin, but fairly absent from the area where we had a 60% chance for the severe winds. That said, there is still a line of thunderstorms along the front extending from north central Wisconsin southwest towards Omaha, and some more reports could come in to help verify that little bubble a little later tonight. So far, the forecast put forth by the SPC looks as though it was good, but perhaps it’s safe to say this wasn’t quite the event they were expecting in Norman.
Once again, the earth has opened up following a good dose of rain and swallowed everything above it. This time it happened in Tampa, when a 20′ by 20′ hole gobbled up part of a parking lot, the lawn in front of a condominium complex and, of course that delicious 1995 Toyota Camry. I’ve heard that the Earth’s crust loves Japanese food.
No word on anything special that might have caused this sinkhole. The last we saw a sinkhole, it was in Guatemala and had been caused by Tropical Storm Agatha, which dumped an enormous amount of rain on the city. Tampa typically sees an exorbitant amount of rain, on the order of 6 and a half inches for the month of July, and there weren’t any tropical systems in the area that might generate a marked increase in rainfall, and in fact, Tampa only reported only about a tenth of an inch of rain yesterday, and none the day before. IT appears this may have just been another case of a leaky pipe, natural spring or just bad luck.
Now that we have had our first Feature Forecast on the new site, thanks to Dan Thomas of WSMV in Nashville, I was thinking of other ways to bring the weather community to you. Every few weeks, I’ll link to any and all blogs from the city in question that I can find in any post that fits for the day. I’ll tell you early in the week, in case you are aware of any sites for the area that you might want me to link to. Does that make sense? Probably not. But we’re going to give it a shot on Friday when we look at Wasau Wisconsin to see what they have to offer! We’ll see how this goes.
For everybody on the East Coast who wanted a warm, sunny holiday weekend, they certainly got what they wished for. As mentioned in an earlier post, The Mid-Atlantic up through New England baked earlier this week as monster ridge of high pressure set up shop and didn’t budge for nearly a week. While the actual weekend was pretty toasty, Tuesday and Wednesday were the hottest of this whole episode. Most areas in southeastern NY, CT, NJ, and eastern PA cracked 100 Wednesday, and Newark topped 100 for 4 straight days, only the third recorded instance of that happening (1953 and 1993). What’s more remarkable, given the sheer volume of people living in the area affected by the worst heat, was the fact that (as of last reported count) only 5-6 people died as a direct result of the heat. This goes to show that word got out well ahead of the heat wave about its’ intensity and knew where to go to keep cool. Hopefully that count stays low when the official total comes in. In any event, it’s clear that people have learned from the 1995 Chicago heat wave how to take care of themselves and others. Kudos!
The difference between a summer and winter ridge is that in the winter, clear skies over night mean that temperatures over night plummet to well below zero. This is most common in the interior of the country, where they are far away from the warming effects of the ocean. In the summer, the persistently sunny skies inevitably lead to warming conditions. This is the case along the east coast, as you may have heard, where they haven’t had any rain or cause to break up the sunshine for over a week, and temperatures have responded by climbing into the upper 90s, even triple digits in some of the larger cities which will be aided by the concrete and asphalt in their quest for higher temperatures.
The east coast is also aided by the fact that the atmosphere isn’t as soupy in the mid Atlantic as it is further south in places like Atlanta and Birmingham, so the lower moisture don’t inhibit temperatures looking to skyrocket. Temperatures will continue to be toasty tomorrow for the east coast, and by toasty, I mean dangerously warm, in the neighborhood of 100+ degrees for many cities. Thursday may finally spell relief when a low in the Atlantic could bring some clouds and cooler weather.
It should be noted that with the flow of ridges, it is typically stagnant underneath them, as with the Megalopolis, however on the western flank, there is southerly flow, which could mean warmer temperatures, and almost certainly soupy weather in the Mississippi Valley as well, though there will be more widespread thunderstorms for residents there to cool off with.
Stay cool, residents from Concord to Charlotte! Only a couple more days to go!
There was really no competition this month. Well, there was some last minute jockeying for position for numbers 2 through 5, but The Weather Channel simply ran away with things this month. It’s turning into a strong year for our friends in Atlanta.
