The Big Uneasy: Slow motion weather disaster in progress
Even after (a 2nd) landfall, Isaac continues to deal surprises.
Isaac slows to a crawl overnight, lingering over open water just offshore. That allowed Isaac to feed off of 82F+ degree water in the Gulf of Mexico and batter the New Orleans area through the night.
With 9" of rain already down in parts of New Orleans and the storm's eyewall lashing the city today, it's not a stretch to say that the forecast 20" rainfall totals will "verify."
NEXRAD "storm total precipitation" estimates show widespread 6"+ rainfall totals
So far the pumps and levees seem to be holding. But remember, Katrina did not show her devastating blow until well after landfall. We thought we dodged a bullet. It will be at least Thursday, or even Friday before we can safely say the New Orleans levee system withstood the test from Isaac.
From drought to flood:
Isaac's rains will literally push some areas from drought to flood overnight.
As the storm crawls north over the next 2 days, flooding rains will spread into some areas hit hard by the drought of 2012. Arkansas, Missouri, Illinois and Indiana could see 6"+ rainfall totals from Isaac by Labor Day.
It's too late to help crops this year, but will help recharge soils & rivers. Rainfall from Isaac should help raise water levels along the southern portions of the nearly bone dry Mississippi River.
Minnesota Forecast: Late summer heat wave builds next 48 hours
Remember the hum of your AC unit? You may hear the chorus of air conditioners across Minnesota the next 2 days.
A "hot front" is pushing into Minnesota today.
Temps will soar into the 90s in most of Minnesota today and tomorrow. In fact, temp forecasts for tomorrow show warm enough air about 5,000 feet above ground level to generate some 100 degree readings for southern Minnesota Thursday afternoon. Right now I'm sticking with my forecast of 100F for the metro Thursday PM.
If we get to 100 tomorrow, it will be the 3rd time this year, the most since 1988 when we sufferted through 4 days of 100+.
Satellite images show no big cloud masses to save us today from late summer sunshine that will boost temps. It could be worse; at least dew points are holding in the lower 60s in most areas.
The record high at MSP today and tomorrow is 96 degrees, there is a chance we may challenge that record both days.
A cooler front will ease into from the north Friday, and temps should fall back into the upper 80s, with dew points in the comfy lower 50s by later Friday.
Once in a "Blue Moon"
If you've been waiting for those things that only happen "once in a blue moon" Friday is your day.
The moon is full for the 2nd time this month on Friday at 8:58am. The first full moon occurred August 1st.
No the moon is not really blue. "Blue moons" occur on average every 2.8 years, so the next one won't come until July 31st of 2015!
10" to 15"+ rainfall totals with Tropical Storm Isaac
60-75 people rescued Wednesday as Isaac's storm surge pounded Plaquemines Parish SE of New Orleans
Drought buster - Isaac may ease drought in some areas
93F high temp at MSP Airport Wednesday
27th day of 90+ degree heat in 2012 in the metro
90s again Thursday but 100 degrees not likely now Thursday
Cool front slips through late Thursday PM
40s dew points? Much less humid & more comfy by Friday
Isaac deluge slides slowly north:
So far, Isaac's wrath falls under the category of...bad, but it could have been worse.
Over 10" of rain has drenched parts of Louisiana, and some 15"+ rainfall totals are likely.
A 10 foot storm surge invaded Plaquemines Parish, the Mississippi Delta region that juts out into the Gulf of Mexico. NBC news reports 50 to 75 people were rescued in Plaquemines, some pulled from attics by boat.
Overall the pumps and flood gates appear to have worked as designed in New Orleans. That's great news 7 years to the day after Katrina flooded the city.
Isaac's rains are a good news bad news scenario for many.
The bad news is 5" to 8"+ rainfall totals will cause short term flooding.
The good news is that as Isaac spins north, 6" to 8" rainfall totals fan out in an arc from Arkansas to St. Louis and central Illinois toward Indy. There arras are in severe to extreme drought and can use some heavy soaking rains.
It may be too late for crops this year, but Isaac will recharge soils and rivers and may be a big step toward preventing a multi-year drought in some parts of the Midwest.
Minnesota Heat: 90s again Thursday...but cool front slides through
Our late season heat wave is here, and 90s are back through Thursday.
A cool front will slide south a little earlier than the models indicated on Thursday...and that should save Minnesota from triple digit heat Thursday.
Still days 27 & 28 of 90+ heat this summer is the highest number in over 5 years. We sweated through 27 days of 90+ heat back in 2007.
Is it just me, or does 93 degrees actually feel pretty good now?
