A broad upper ridge will take up shop in the week ahead across the Ohio Valley and Northeast. Meanwhile, a trough will settle into the Northwest. Well above normal temperatures can be expected across the central portion of the country, extending from the West Coast into the Ohio Valley and Mid Atlantic. Below normal temperatures will be found across the Pacific Northwest and along the Gulf Coast. An active weather pattern is on deck across the northwest Gulf and eastern Great Lakes. Elsewhere, generally quiet times are expected.We think around 0.50” of rain will fall during the forecast period (most likely not until late in the week).
Forecast Period: 09.11.21 through 09.18.21
A quiet weather pattern is expected to dominate this forecast period, locally. A southwesterly airflow will draw unseasonably warm and muggy air northward today, but really begin to be felt as we progress into early next week. We aren’t talking about organized precipitation chances until late in the forecast period (centered on Friday and next Saturday) as a cold front slowly begins to sink south into the area. Until then, an extended period of warm and increasingly humid air will dominate the weather headlines.

The upper air pattern this week will feature a trough across the Northeast and Great Lakes with an upper ridge anchored over the Four Corners.
Temperatures will run below average from the Ohio Valley into the MS Valley, with well above normal temperatures expected across the West.
Most of the country can expect below to well below average precipitation in the week ahead. The one exception? Northern New England.
We only forecast 0.10″ to 0.25″ of rain here in central Indiana during the 7-day period.
Forecast Period: 09.05.21 through 09.12.21
A very quiet weather pattern will settle into the region as we go through the upcoming week. The one exception to that is Tuesday night as a cold front quickly passes through the area. Moisture levels will return ever so slightly ahead of the boundary and may be enough to produce a couple of storms Tuesday evening (widely scattered coverage). The front will help to reinforce the dry airmass in place, along with provide cooler temperatures for mid and late week. As we look ahead beyond this week, indications are that things will moderate and turn a bit more active (though that’s admittedly not saying much, considering just how quiet things will be this week).
