Record rainfall to areas of dense fog tonight
It was a record breaking rainfall for Indianapolis today. 1.61? is the new daily record and many locations in the metro area and southward received 1-2? from rounds of showers and storms.
In just a few hours the city nearly doubled the rainfall from the first 22 days of the month… this was truly what the doctor ordered for what was becoming parched landscape around the area.
Unfortunately cities like Lafayette, Terre Haute, Muncie and Kokomo fell on the short end of the rain stick with values well less than one inch. Lingering spotty showers and some rumbles of thunder are possible south of I-70… with a slow clearing to take place from the northwest to southeast.
Dew points at the time of this posting remained in the tropical category. So the Muggy Meter this afternoon hangs in the uncomfortable range, but will drop into the pleasant category by Thursday morning as drier air advances into central Indiana.
The combination of clouds clearing and saturated ground tonight will produce areas of dense fog and low clouds for the morning commute. It’s possible visibility may be low enough to near Advisory criteria so check back for updates.
Once morning fog dissipates, Thursday will be one our better days… with sun and clouds, pleasant highs in the 70s and a refreshing breeze. This is perfect timing for opening Brickyard 400 festivities at Indianapolis Motor Speedway. Friday will also be nice before an unsettled set up arrives for Brickyard 400 weekend.
Highs Friday will be in the upper 70s to near 80, but jump into the upper 80s and lower 90s on the south side of warm front Saturday. Late Friday night and early Saturday morning this front may trigger the first of a few rounds of storms set to move through this weekend.
Additional storms are likely Saturday night into Sunday morning and to be determined how quickly they’ll move out during Brickyard 400 Race Day. Could be a challenging weekend at IMS. We’ll narrow down timing and coverage in the coming days.
Long range guidance has done but strengthen the idea of considerably below normal temperatures to wrap up the month of July. The air mass within the base of a sharp trough in the eastern US will deliver temperature anomalies of 10-20 degrees over a good chunk of real estate.
We may be challenging the record books Monday into Wednesday. Here’s a list of record low temperatures to keep an eye on next week:
Monday / Record Low Maximum: 72 (set in 1928 & 1925) / Forecast: 72
Tuesday Record Low: 51 (set in 1881) / Forecast: 53
Tuesday / Record Low Maximum: 72 (set in 1889) / Forecast: 71
Wednesday Record Low: 51 (set in 1965) / Forecast: 53
Have a great evening and please check back for changes – Sean Ash
