It was a cool morning with some patchy shallow fog & lows 46-55. It was about as cool as the morning of September 5.
WLFI: 49.3 September 5.......49.3 September 24
Still not as cool as the unusually cool/record cool June 14 morning (thermometer down, so no station number, but 43 at the Purdue Airport):
Today with sunshine/clouds & a nice southwest wind, we saw highs of 75-79.
Quite a severe weather outbreak is underway from southwest Ontario to Kansas.
Hail up to tennis ball size, winds to 80 mph & 4 tornado reports have come into SPC.
We get the leftovers of those storms in the form of a few spotty showers & t'showers Wednesday morning.
A break should follow with partly cloudy skies & south-southwest winds 15-30 mph, then a few isolated showers/t'showers with the actual cold front in the late afternoon.
After nice 69-75 Thursday (with northwest wind) after 49-55 in the AM, a few isolated storms initially should give way to increasing showers & storms Friday evening-night.
Highs Friday should run 80-85 north to south with around 81 at Greater Lafayette with strong southwest winds.
We will monitor, as some Friday Night Frenzy games may be affected with lightning & downpours.
Some scattered showers/storms are possible Saturday with highs 70 north to 82 south & around 80 at Greater Lafayette. Winds will tend to be east-southeast north to southeast central & south-southeast south.
Blizzard will be underway in the central & northern Rockies with a low-topped squall line in highly-dynamic environment from Nevada to Utah & western Colorado.
A few more storms are possible Sunday with southerly winds & highs 80-87 north to south with southeast to south winds north to south.
Meanwhile, all-out blizzard will be underway in the northern & central Rockies with severe weather Minnesota & Dakotas to Texas, along with flooding rainfall.
Look dry, windy, very warm to hot & humid Monday-Wednesday with highs 88-91 with overnight lows of 69-74. Heat indices may run 92-96.
These are at/near record warm levels.
Check out the Total Precipitable Water anomalies for Friday-Tuesday. Anything in darker green or blue is an unusually high amount of water to squeeze out for the time of year.
Flooding rainfall & severe storms will continue daily from Texas to Wisconsin in this "backed up" & "blocked" pattern by Alaska & Greenland warm upper ridges & hot upper ridge in the Southeast U.S. Very cold upper trough will be locked in southern Canada & in the western U.S.
Note the connection to the very active tropics in the Pacific & a bit from the southern Gulf.
Note the record cold & snow in the West & record heat & unusually-high moisture & high dew points in the East.
Temperatures to 30 degrees below normal in the Rockies...............20-25 degrees above normal in the East.
Record lows may occur as far south as central & southern California & then all over Oregon, Washington, Idaho, Montana & Utah.
We will eventually get the rain & storms Wednesday evening-night to early Thursday morning.
1-2.50" of rainfall is possible.
A couple isolated severe storms may be embedded, but it does not look like anything widespread severe.
Strong Canadian surface high brings Fall!
Real Fall weather is unleashed behind strong cold front with widespread below normal temperatures.
Widespread lows in the 30s to 40 are likely around October 4 & 5, even 6. Patchy frost is likely.
As we approach mid-October, pattern flips & we enjoy a taste of Summer again with temperatures as much as 15-20 degrees above normal (80s).
