Tuesday Evening Weather Notebook…

It’s been a cool and dry start to the month of September. Through the first few days, IND is running 0.70° below normal and 0.44″ below average precipitation. 


The upper ridge currently in place will deliver more late summer heat through the end of the work week. It’ll remain mostly dry, as well. 


Much better rain and storm chances will have to be built into our forecast Friday into Saturday, courtesy of a cold front moving into the region. 


A much cooler regime will settle into the region over the weekend. Highs behind the front in the 70s with lows in the 50s will be common- after rain potential of 1″-1.5″ for most. 


A reinforcing shot of cool air will arrive the middle of the following week. Early indications suggest the second shot of fall-like air will be even cooler than this weekends’ and could feature widespread 40s at night.

Warmth Next Week Gives Way To A Cool Mid Month…

The refreshingly cool couple days we’ve recently enjoyed will begin to give way to moderating temperatures today.  Humidity levels will remain pleasant and it’ll be a great Labor Day weekend to spend time outdoors.  Highs will top out around 80 today and into the middle 80s Sunday.  Labor Day will feature the mercury climbing closer to the 90 degree mark.  – Fitting, I suppose, for the unofficial end to summer.

Humidity levels will be on the uptick come Monday evening and Tuesday as Gulf moisture is transported northward.

GulfMoistureIt’ll be a downright hot week, as well.  Temperatures will top out around 90 through the end of the short work week.

gfs-ens_T2maMean_us_4As we rumble into next weekend and the following week indications continue to point towards wetter and cooler times.

After a dry week ahead, rain and storms will come with that increased humidity next weekend.

gfs-ens_apcpna_us_7Early numbers off the press suggest 1″-2″ rains possible next weekend.

The increased rain and storm chances signal another shift in the pattern towards a cooler one just beyond the Day 10 period.  From experience, I would look for this trough around mid month to trend deeper (more significant) as time draws closer.

Thursday Evening Rambles…

1.) A big ole ridge will supply oppressive heat and humidity across the Mid West this weekend.  Unseasonably hot temperatures will combine with downright “soupy” air to create heat indices between 105-110 degrees across central IN this weekend.  Take it easy and implement frequent breaks if your plans take you outdoors.

2.) Similar to what we’re seeing on radar this evening, thunderstorms will also make an appearance from time to time for some.  With an atmosphere loaded with moisture, any storm that develops will be plenty capable of producing “frog straggler” type rainfall rates.  Perhaps there will be a couple periods of more concentrated storm activity, focused on late tomorrow night and early Saturday, and again late Saturday night-Sunday morning.  We’ll keep an eye on things.

3.)  The pattern is one (as has been the case all summer) that’s transient and the situation that develops to wrap up July and open August is an all-too-familiar look around these parts: NW flow aloft that offers storm potential, along with seasonal to slightly warmer than average.  It’s a wet look, overall.

This is what the upper air pattern should look like as we close July- 10 days from now (hard to believe)!

4.)  Looking further ahead, the latest JMA Weeklies continue to suggest the most sustained hot pattern should remain across the west as we rumble deeper into August.  That’s not to say we won’t deal with periods of hot weather here at times, but sustained heat will be hard to come by with such a pattern…
