Weekly #AGwx And Severe Weather Outlook…

Updated 08.15.21 @ 8a

The 7-day period will be dominated by an eastern ridge while a trough carves itself into the inner-mountain West.
Below normal temperatures will take up shop across the inner-mountain West and spread throughout the south. Meanwhile, anomalous warmth will prevail across the upper Midwest, Great Lakes, and into the Northeast, and Mid Atlantic.
Tropical moisture will lead to well above normal rainfall across the Southeast and into southern Appalachia.
We forecast on average between 0.50″ and 1.00″ of rain across central Indiana during the week ahead.

Forecast Period: 08.15.21 through 08.22.21

The past 36 hours has provided a nice change of pace as of late with lower humidity and cooler temperatures. (Several reporting sites across northern Indiana are in the lower 50s this morning with middle 50s as far south as the Indianapolis suburbs). As we look to start the new week, humidity will be on the increase along with a daily chance of scattered thunderstorms beginning as early as Monday, continuing Tuesday. We will try and inject briefly drier air in here Wednesday which should reduce coverage of “splash and dash” storms before scattered storms return to close the week. As we look ahead to Saturday, better storm coverage is expected as a cold front moves through the region.

A couple of other items of interest on a broader scale include the first snow of the young season falling across the northern Rockies this week, as an early shot of winter-like air descends south from Canada. Also, from a tropical perspective, we’ll keep close eyes on what comes of Fred and Grace. As it sits today, we still don’t anticipate impacts here in central Indiana from either systems.
