Highs today reached 70-77.

The 76 at the Purdue Airport (outside of the 72 on Saturday) is the coolest day-time high since May 31.

The forecast low of 51 tonight would be the coolest at the airport since May 13.

We also hit 76 today at our WLFI weather station site, which (outside of the 72 we measured Saturday) is the coolest day-time high since June 1.

That forecast low of 51 at this site would be the coolest since June 1.

The record low at Purdue University 1879-1953 & the Purdue Airport 1954-present is 47 set in 1912.

Overall, lows tonight will run 48-55.  Patchy shallow dense fog is possible in largely low areas & areas around water due to the cool moist air atop the warm water & ground. 

Overall, the rest of the week looks good.  It is just going to get warmer.

It is very warm to hot & muggy then OPPRESSIVE THE weekend & into next week, however.  There are signs we may get dew points up to 80 mid-next week!

Wednesday:  76-80 for highs/50-56 for lows

Thursday:  78-83 for highs/56-61 for lows

Friday:  82-88 for highs/63-67 for lows

Saturday:  86-90 for highs/66-72 for lows.............dew points 67-72: heat indices 89-95

Sunday:  88-91 for highs/68-74 for lows................dew points 71-74:  95-100

Monday:  88-92 for highs/70-74 for lows..............dew points 72-77:  98-104

Tuesday:  87-92 for highs/70-74 for lows..............dew points 72-77:  98-105

Wednesday:  88-92 for highs/71-75 for lows.......dew points 75-80:  99-109

The better mid & upper levels winds will reside well northwest of our area, but we will be in a pretty active storm track with cooler weather & upper trough in the Northeast & hot upper ridge with intense heat just southwest of our area.

We will tend to be on the hot, humid side, but be in the zone of transition with multiple round of storms passing through.  Lack of better wind fields aloft may preclude better severe weather risk.  However, MCVs will locally-enhance shear & thoughts are that we may have multiple time periods of MARGINAL to SLIGHT RISK in the Sunday to next Thursday period.

It will be a warmer & wetter than normal regime.

At this point, this period just prior to mid-August looks the wettest with the highest occurrence of showers & storms for the month, overall.

Trend is for brief spurt of cooler weather at some point mid-August, then heat dominating in largely two main waves late August to early September.

Even tonight, trend is for a bit cooler than normal weather mid-September.

Latter August to early September features a drier regime with rainfall adding up slightly below normal (unless we see a tropical system that alters things).

La Nina is still up for Fall-Winter-Spring 2020-21 with the sun beginning to climb out of its long slumber.  More & more sunspots are appearing, so the current solar minimum may be ending.  This has implications for the long-term weather pattern.

At this point (which I will have another post soon exactly where the drivers of Fall-Winter-Spring stand soon) there continues to be a trend of a dry, warm Fall, a wet, mild winter & a spring with much more severe weather than previous springs, wetter pattern & overall above normal temperatures.  It may be one of the earlier starts to spring than we have seen in recent years.

Heat & drought will need to be monitored for next summer as traditional La Nina-induced heat waves & drought in the southwestern U.S., southern Plains & Southeast U.S. expand northward somewhat.
