Heat Builds This Week

By · August 19, 2013 at 6:13 pm

Summer makes up for lost time in central Indiana over the next seven to 10 days, as the much advertised warm up builds in across the Ohio Valley.

EVENING

Enjoy what will be a comfortable evening in central Indiana… with temperatures sliding into the 70s by 8pm.  Lows tonight range from 60 to 65, and light wind will allow for some patchy fog to develop by sunrise.

With essentially no change in the overhead air mass, Tuesday will be near carbon copy.  Hazy sun quickly pushes temps into the 80s by midday and into the mid 80s for highs again.

MUGGYMETER

For now the Muggy Meter remains comfortable, but atmospheric moisture gradually increases the next 24-36 hours.  Expect the humid heat by mid-week, and combined with an upper level disturbance will help trigger scattered storms Wednesday.

A week ago we began highlighting the return of typical summer heat.  For now the “hot dome” remains in the western U.S…but as expected the corresponding upper ridge slides eastward by the end of the upcoming weekend.

The end result will be a string of hot, mostly dry days… and unfortunately deteriorating air quality.  Pollen (specifically ragweed) count climbs along with pollutants within the stagnant air.

We’re digging a rainfall deficit of nearly 3″ since June 1st.  There is some “localized” hope of a .25″ to 1″ between Wed 8am – Thursday 8am…but not everyone will get wet.

It’s slim pickings for precip in the long range due to the building upper ridge… and heat steals the headlines overall.  Thanks for reading the blog and have a great evening – Sean Ash
