Air quality degrades as heat spreads east
Posted by: Angela Fritz, 06:53 PM GMT del 29 Giugno 2012 +39
For the seventh day in a row we're talking about heat as it spreads into the Mid-Atlantic and East Coast. The hottest temperatures in the country will be from Missouri southeast to Georgia and north to the Washington D.C. area. Why not Florida? Moisture tends to keep the temperature regulated; the worst heat waves this country has seen have also coincided with widespread drought. Given the extreme to exceptional drought that many states can't get rid of, this heat wave isn't all that surprising. Air quality is becoming more of an issue the longer the heat sticks around. Air quality alerts have been issued for many major cities from Kansas City to New York, including Chicago, Detroit, and Atlanta. Chicago is seeing some relief from the heat today in the form of thunderstorms—northeast Illinois and northwest Indiana are under a severe thunderstorm watch. Washington D.C. is pushing its all-time record high of 106°, which is the high that BestForecast is going with. You can see the all-time record highs for almost all major cities here.


Figure 1. BestForecast high temperature for Friday.

Our Weather Historian, Christopher C. Burt, will likely post two blogs today and tomorrow this week's heat, but for now, he wraps up Thursday's significant temperature records:

• 109° in Chesterfiled, Missouri (well short of state monthly record of 112°)
• 108° in Lawrenceville, Illinois (ties all-time state June monthly record of 108° at Palestine in June 1954)
• 108° in Huntingsburg, Indiana (well short of state monthly record of 111°)
• 107° in Defiance, Ohio (1° short of all-time state June record-108° in Germantown in 1934)
• 111° in Evening Shade, Arkansas (short of state June record of 113° in 1936)
• 108° in Smyrna, Tennessee (short of 110° state record in 1936)
• 107° in Little Rock, Arkansas (all-time June monthly record)

Waldo Canyon Fire now 15% contained

The Denver Post is reporting that 346 homes have been lost to the Waldo Canyon Fire, which is burning northwest of Colorado Springs. They also report that one person has died and another is missing in the area of the blaze. The fire has been 15% contained since Thursday night, and the acreage is down to 16,750, welcome news to a terrified city.

Invest 97L

A tropical wave in the central main development region of the North Atlantic is still producing thunderstorm activity as it moves west, and the National Hurricane Center has increased its chance of development to 20%. 97L's circulation continues to be moderate and in the past day has realigned with the thunderstorm activity, which is likely why NHC gave the go to invest the wave and begin running models on it. This wave continues to be in some moderate wind shear, 10-15 knots, and sea surface temperature is around average, 28° C (82° F), which is warm enough to support tropical development. Many of the track models are forecasting 97L to continue trekking west into the Caribbean, crossing the Lesser Antilles around July 1.

Quoting winter123:
All three Atlantic areas of interest went "poof" overnight. I'm starting to believe the "6 more named storms this season" forecasts. The atlantic is super dry and fronts are no longer dipping way down and stalling (all four storms so far have formed from fronts). I feel like we won't have one named storm in July.
You people kill me it's the last day of June! We are just one month into the season.No one knows what will happen no person or model!!!!!

Good Morning. Most impressive thing out in the tropical Atlantic this morning is how nicely the ITCZ has developed and is rolling along in the "usual" position for this time of the year nearer around the 5N mark. That slow rise towards the 10-15N line will begin in earnest over the next few weeks so time to start looking at the long term models for development of these African waves. 97L was an outlier in terms of it's much higher trajectory out of the box but has not been able to get going.

Don't have a clue whether we will get another storm in July but the Cape Verde season is the one to watch out for this year. Even if the storm numbers level out in late September because of El Nino induced sheer increases, it only take one or two devastating hurricanes to make the year memorable and I am not liking the current ridging pattern of the A-B high which could steer some of these CV systems towards the Caribbean and Yucatan Channel.

Time will tell...........Lot's of chores today and activities for the Kid so Have a Great Weekend.

Guys you are funny. Seriously! Saying what's left of 2012 will be inactive is not reasonnable. What we experienced last night with our AOI's sure occured in 2010 or 2005... and occurs EVERY SEASON. So please come on lol!
Saying the rest of this season will be inactive would be a mistake. Even the experts agree that this will be a normal year....Many landfalls have occurred in a normal year.

I DON'T THINK ERNESTO WILL AMOUNT TO ANYTHING IF HE FORMS...he has 2 things fighting against him the SAL quite a bit of dust and the sst are quite cool in that part of the caribbean..he also has to deal with strong shear by the time hes in the area...not a really good outlook for ernesto..


Where is Ernesto or even soon to be named Ernesto, I can't see Ernesto forming anywhere. Not one T-wave looks to have a chance at forming into anything at the moment. Ernesto could develop at the CV's or it could develop in the GOM or the BOH. We won't know what Ernesto could become until it develops.

It is completely attached to the ITCZ so I'm not sure, but if the spin continues to improve we might get something to watch. Disturbances do form from the ITCZ from time to time, weirder things have happened.
