Weekly #AGwx And Severe Weather Outlook…

Updated 07.11.21 @ 8:18a

Persistent ridges will remain in place along both the East and West Coast with a persistent trough in the central through the upcoming 7-day period.
The cooler anomalies in the central will be mostly associated with lower than average daytime maxes (due to the unsettled weather). Hot weather will remain in place across the West.
Above normal precipitation can be expected through the Ohio Valley, Great Lakes, and interior Northeast through the course of the upcoming 7-days.
We forecast widespread 2″ to 3″ rainfall totals across central Indiana through the upcoming 7-day period with locally heavier amounts.

Forecast Period: 07.11.21 through 07.18.21

A persistent and rather stagnant upper pattern will remain in place through the upcoming 7-day forecast period. A cut off upper low that will be responsible for our unsettled conditions to open the work week will lose it’s influence on our weather as it gets absorbed in the westerlies by midweek. This will result in coverage of showers/ storms going from “numerous” (now through Tuesday) to “isolated” Wednesday and Thursday. Don’t get used to the drier trend though as a new trough will settle into the Plains during the 2nd half of the week, increasing coverage of showers and thunderstorms yet again Friday through next weekend. With such a rich, tropical airmass in place, the threat of localized flash flooding will remain high.
