Highs today reached 65-70 after lows of 55-60 this morning.

Multiple reports of funnels were received this evening.  These are cold air funnels associated with low spinning in Illinois.  Our environment is vorticity-rich or the air parcels have a lot of spin.  Combined that with some colder air aloft bubbling up cumulus towers, rather moist surface to low levels & some shallow CAPE & you have small funnels condensing from the spotty showers & cumulus clouds.

They rare, if ever, touch down, but a few times they have.  The last one to touch down in our area was in June 2006 when one blew the a door off a quonset hut shed & knocked a couple of limbs down on a farm near Odell.  Winds were likely around 70 mph.

This evening, most of the funnels where high up, short & rope-like. 

This was a larger one in a shower near West Lafayette this evening.  It was also much closer to the ground than the others.  Image captured by Josiah Maas.

Lows tonight will run 55-60 (59 Greater Lafayette) as shower coverage increases late (by morning) from 30% to 60%.

Rainfall coverage will go up as spinning upper low in Illinois moves south, rather than east due to juggerknot from upper low in Georgia moving northeastward & Tropical Storm Arthur.  Also, warm to hot upper ridge dominating from northern Mexico to Ontario & Quebec will tend to block its movement to the northeast, as well.

Rainy weather in the morning should give way to decreasing shower coverage (60% to 30%) & some breaks in the clouds here & there in the afternoon.

Highs will eventually reach 65-70 (70 Greater Lafayette).

An isolated funnel or two is possible in the afternoon-evening (though doesn't look like as many as we had this evening).

A few isolated showers are possible Wednesday morning-midday, otherwise we will see clouds with some sun with breaks in the clouds & highs 65-72 (70 Greater Lafayette).

We will warm Thursday to 72-78 (75 Greater Lafayette), followed by 77-84 Friday (81 Greater Lafayette) with sunshine.

The weekend looks muggy, breezy to windy & summer-like with highs 85-90 with some storms possible Saturday night & again late Sunday to Sunday night.

SLIGHT RISK parameters show up over the area.

Some storms are also possible late Monday with highs 85-90.

MARGINAL to SLIGHT RISK parameters show up over the area.

Overnight lows for all of these nights will only drop to 65-70.

On all three days, it will feel more like 91-96 with the higher dew points.

All of next week looks very warm to hot & humid with highs 85-91 & lows 65-71 with heat indices reaching 91-97.

SLIGHT RISK does show up next Wednesday, but after that, all of the organized severe weather risk is well northwest of our area May 28-June 4.

June 4 & 11 show some severe risk.  Above normal temperatures look to dominate with a lot of very warm to hot, humid days currently forecast.

Again, main corridor of flooding rainfall & severe weather is shaping up Manitoba to Kansas & not so much here at the moment.

We will monitor.
