Weekly #AGwx And Severe Weather Outlook…

Updated 08.28.21 @ 6a

A persistent trough will remain in place across the northern Rockies while weak ridging takes up shop across the Great Lakes region.
Warmest anomalies through the forecast period can be expected across the Mid-Atlantic and central Plains, into the Southwest. The northern Rockies will remain cooler than normal. The cooler than normal conditions across the central Gulf Coast region is associated with the daytime highs being lower as Ida moves north early in the period.
The biggest focus through the middle of the week will have to do with the remnant moisture associated with Ida. Active times will return to the upper Midwest as well.
We forecast 7-day rainfall amounts to check-in between 1″ and 1.5″ for most of central Indiana.

Forecast Period: 08.28.21 through 09.04.21

The period will open with an active weather pattern. A cold front will slowly press south through early week. At the same time, Hurricane Ida is forecast to make landfall along the north-central Gulf Coast (likely along the LA coastline) Sunday afternoon, and as a major hurricane at that. The remnant moisture of Ida will lift north before curling east. Eventually, we believe the remnant moisture of Ida will get tangled up with the aforementioned cold front. While we’ll need to keep a close eye on data to see if any adjustments are needed early week, as of now, we believe the heavy rain threat will lie just south of our immediate area (more so along and south of the OH River). We’ll keep a close eye on things. Regardless, scattered to numerous showers and thunderstorms are expected as the cold front sinks south. By midweek, the region will be in a much drier (and somewhat cooler) northeasterly airflow. Dry conditions are expected to continue into the holiday weekend ahead with slowly moderating temperatures.
