53 dew point yesterday.
73 dew point by this evening.
77 dew point expected Saturday evening.
56 dew point predicted for Sunday afternoon, by far the cooler, more comfortable day of the weekend.
* 11 days above 90 so far this summer. Average for a Twin Cities summer is 13 days.
A Week's Worth Of Records. 2,649 records to be exact, mostly record daytime highs and record (warm) nighttime lows. Ham Weather has an interactive look at the records from coast to coast here.
Here We Go Again. The combination of upper 80s and a dew point in the mid 70s will make it feel like 97-100 today; dew points may rise close to 80 again Saturday - oppressively/dangerously humid, creating a heat index in the 100-105 range. A surge of cooler, drier air should make for a MUCH more comfortable Sunday, statewide.
Another Free Watering. Models are suggesting significant rainfall amounts with scattered T-storms, some possibly severe later today, again Saturday. Right now the NWS is predicting about 1.5" of rain for the metro by Saturday night.
Tropical Downpours? The NAM/WRF model prints out some 4"+ amounts for northeastern Iowa, closer to .5 to .75" for the metro, with a band of 1-2" amounts from near Alexandria eastward to St. Cloud and Hinckley over the next 84 hours.
Remarkable In Scope & Duration. Once again today the heat index will top 100 degrees over nearly 2/3rd's of the USA, as high as 108 at New York, 114 in Washington D.C. and 110 at St. Louis. After a one-day break from the humidity a dew point rising into the mid 70s will trigger a heat index close to 100 in the Twin Cities. Meanwhile, dry desert air will mean a downright reasonable heat index of 93 in Las Vegas. Go figure...
Today's Severe Risk. According to SPC the risk of severe storms will be greatest from the Dakotas to the Twin Cities, Madison, Chicago, Detroit and Columbus, Ohio, hail and damaging winds possible along the boundary separating oven-like conditions south from 50-degree dew points north.
Friday Puddle Potential. Here's the WRF/NAM model forecast, valid at 4 pm today. Storms may be severe from near Pierre, South Dakota to Alexandria and St. Cloud, Minnesota. More strong/severe storms may sprout from Des Moines and Omaha to the Front Range of Colorado. Storms capable of downpours will flare up over the Mid South, more sea-breeze storms for Florida, while Texas stays dry - and the western third of the USA is warm and dry.
- 5:45 p.m 7/20: The high temperature Wednesday in Rockford, IL hit 100 degrees. This is the first back to back 100 degree days in 23 years, per NWSChicago.

- Syracuse, NY (179" of snow last season) just hit 100 deg. for 1st time since '02. Nearing all-time record from 1936!
- @dallas_news "Yes, we officially hit 100 degrees this afternoon. That's 20 straight days, tying us for 5th longest streak". (Thursday)
- Elmira, NY breaks their ALL TIME record high by hitting 104. (Thursday)
- Fort Smith tied the record for consecutive days with 100 degree temps (17) by reaching 106 F Thursday; record falls Friday.

- Including Thursday, Amarillo, Texas has had 27 100°+ days so far this year, breaking the record of 26 set in 1953.
- A heat wave baking the central and southern United States was blamed on Wednesday for at least 22 deaths this week as forecasters warned that the abnormally hot weather could last into August as it moves east.
- With the number of days of extreme heat and humidity of the current heat wave, it may be more significant and impact a larger area than the deadly 1995 heat wave.
- The National Weather Service said 141 million people in 33 states were under a heat advisory or warning because of the soaring temperatures.
- The high heat and humidity have been stressing U.S. crops, particularly corn, which is now in a key growth stage when heat and moisture can cut final yields.
- Grain traders in Chicago and Kansas City also said the drought and heat in the Plains was beginning to cause concern about the fate of next year's output of hard red winter wheat crop, the primary bread wheat of the United States, which is grown in a parched swath from Texas to South Dakota.
- Farmers plant that crop each autumn and harvest the following summer. But if rains did not come soon, farmers may not plant wheat because of the powdery dry soil.

"Mother nature is every farmer’s best-friend -- and worst enemy. Deadly tornadoes, record flooding, and one of the worst droughts in recent history are making this year an especially challenging one for crop growers. In Mississippi, some farmers are facing flooded fields side-by-side with fields that haven’t seen significant rain in months. Billy Whitten can’t remember ever having to deal so much water and so little water at the same time, much less having the two extremes right next to each other. “This is very unusual this year to have the drought and the flood at the same time,” Whitten says. “Normally, when we have a flood, we have some rain to go along with it. This year we’ve had the flood and no rain at all, so we’re just getting it from both ends. We’re either flooded or drought destroyed it.” Flooding impacted more than a half-million acres of farmland in Mississippi. At the same time, 25-million acres, or 84% of the state’s land, is under some form of drought."
"Sandwriting" Billionaire Sheikh Carves Out His Name In Desert In Capital Letters Visible From Space. Now THIS is the definition of cash-flow. Some guys have more time (and money) than good sense, as reported by the U.K. Sun newspaper: "A DESERT sheikh has carved out a big name for himself — by having his moniker etched in capital letters visible from space. Workmen scoured "HAMAD" into the sand on the orders of Abu Dhabi's Sheikh Hamad Bin Hamdan Al Nahyan. The name is two miles across — with letters a kilometre high. It is so huge that the "H", the first "A" and part of the "M" have been made into waterways. The mega-rich sheikh, 63 — a member of the ruling family of Abu Dhabi — in the oil-rich United Arab Emirates — boasts a £14billion fortune that is second only to the Saudi king's."
Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:

- We’re speeding it up: The vast majority of climate scientists are convinced that greenhouse gas emissions from human activities are largely, if not wholly, responsible for current climate change. More importantly, the rate at which we’re putting carbon dioxide into the atmosphere is unprecedented. Consequently, the pace of climate change is also unprecedented. Adapting to major climate shifts is always a challenge, to put it lightly. Past global warming events have caused mass extinctions. With less time to make major evolutionary changes, things could get even uglier this time around.
