Round of rain & storms will arrive after 3 a.m. Sunday morning in our area.
The storms will pull through by 10 a.m., but some scattered, periodic shower action rainfall may linger to early- to mid-afternoon.
With those storms, isolated severe gusts are possible (MARGINAL RISK).
A few showers are possible late afternoon before completely ending.
Highs will run in the 70s with mostly cloudy skies.
South of our rainfall, a flare-up of severe storms is likely across south-central & southern Indiana (SLIGHT RISK). A line may form & sweep through southern & eastern Ohio & Kentucky tomorrow night. Threat is mainly wind.
Looks wet & stormy for the Indy 500 Sunday morning, then some lulling, but another round of storm possible in the afternoon. Delay, abbreviated race or postponement to Monday all seem on the table.
Cold front that works southward late Sunday will move back northward as a warm front late Sunday night to Monday morning (lows 56-65) north to south.
A cluster of storms is possible along & just north of that warm front Monday morning-midday mainly with then partly cloudy skies south of the warm front.
Isolated severe weather is possible (large hail).
Highs should vary from 75 northeast to 88 southwest & around 82 at Greater Lafayette with humid conditions.
Lows tonight will only drop to 67-72 as we all are dry.
Tuesday looks dry, windy, humid & very warm to hot with partly cloudy skies & highs 86-90 & heat indices 90-96.
Tuesday night looks especially warm & muggy & windy with lows 70-75.
Leftovers of big Plains to partial Corn Belt severe outbreak should arrive & pass Wednesday morning. Some isolated severe gusts cannot be ruled out.
It appears that another round of storms may re-develop Wednesday evening-night or possibly early Thursday. Some isolated severe risk is possible.
Cooler, less humid air will follow, followed by much warmer, more humid weather next weekend, then a couple rounds of storms around June 2 & a round near June 10.
Temperatures should average above normal overall with precipitation near normal.
Normal highs/lows for early June are 77/55 to 79/57. Normal rainfall June 1-June 15 is around 2.55".
However, a period of below normal temperatures is likely mid to late June with normal to slightly below normal rainfall.
Normal highs/lows are 81/59 to 83/62 with June 16-25 rainfall around 1.50".
Temperature anomalies for mid to late June:
Rainfall anomalies for mid to late June:
June 26-July 6 looks warmer than normal.
Normal is 82/60 to 84/63.
Rainfall looks near normal.
Normal for June 25-July 6 is around 1.40".
An early season tropical system is possible in the Gulf of Mexico in June. This is not uncommon in an El Nino, but overall hurricane activity should be suppressed in the Atlantic & Caribbean & enhanced in the Pacific. Perplexed by model runs of less than stellar monsoon in the Desert Southwest when the Eastern Pacific will be so active.
This being a traditional El Nino summer ahead, it continues to look wetter than normal. Temperatures should average near normal, but this is mainly due to warmer nights due to considerable mugginess. High soil moisture & more cloudiness will hold daytime highs down overall.
Prolonged mugginess & steamy 70s dew points (event a few days of 80) with this wet soil around & lush vegetation can be expected, however.
