Highs today reached 73-78, marking the third consecutive day below normal (after normal highs on August 2). The last time we had 3 or more days below normal was May 8-13.
Patches of dense shallow fog with a few clouds/patches of clouds are likely tonight with lows 51-56. The record low for West Lafayette tonight (records back to 1879) is 48 set in 1997. Low of 54 is expected.
78-83 is likely Thursday (partly cloudy), followed by 81-86 Friday (mostly sunny) with 87-90 Saturday (with higher humidity & partly cloudy skies).
It will become muggy to oppressive with highs near 90 & lows near 72 Sunday to late next week.
In an active storm track, +1.50" rainfall amounts will be widespread by late next week, it appears.
Nothing screams big severe weather episode at this point, but some MARGINAL to SLIGHT RISK parameters show up a few times as rounds of showers & storms pass at times for 6 days next week.
Dry, cooler & less humid weather looks to return a week from this weekend.
