Weekly #AGwx And #Harvest21 Outlook…

Updated 10.16.21 @ 8:10a

The upcoming 7-day will feature a trough of low pressure along the eastern seaboard and a new trough pushing into the West. In between, transitional ridging will take place through the central.
Above average temperatures will be found across the northern tier with below normal air strung across the south.
Most of the country can expect below normal precipitation this week. The exception being northern New England and the far PAC NW.
We forecast between 0.10″ and 0.20″ of rain here in central Indiana during the 7-day period. That will be associated with a low pressure system and associated cold front Thursday.

Forecast Period: 10.16.21 through 10.23.21

A true fall cold front blew through the region during the overnight. You can certainly feel the difference out the door this morning as northwest winds blow the chilly, much drier air into the region. Highs today will struggle to crack the 60° mark. “Sweater weather, anyone?!” We’ll prep for the first round of patchy frost in outlying areas by Sunday morning as temperatures dip into the mid and upper 30s, winds go calm, and skies are clear.

As we head into the new week, much needed dry time can be expected to open things up as high pressure dominates. Look for a string of sunny days and cool, clear nights. This will give the “nudge” needed to ignite what’s otherwise been a delayed and sluggish fall foliage season.

Our next system of note will arrive Thursday in the form of a low pressure system and trailing cold front. Showers are expected to arrive Thursday morning from the west. We’re not talking about impressive rainfall numbers with the front, itself (on the order of 0.10″ to 0.20″ Thursday), but the period heading into next weekend remains in limbo between forecast models duking it out with the wetter GFS and drier European. We’ll see if we can get more agreement over the next day or two.

Quiet For Now, But Attention Warranted In The 7-9 Day Window…

The big story in the immediate term is centered squarely on the temperature forecast. Frost Advisories are up for our friends across northern parts of the state, northwestern OH, and into southwestern MI. Even a few folks outside of the city, itself, can expect patchy frost (a few weeks early mind you, and another byproduct of the recent dryness) across central Indiana.

There’s no reason to waste a lot of pixels on the short-term forecast as quiet conditions prevail. High pressure will remain in control for the upcoming work week with slowly moderating temperatures. We’ll go from below, to seasonal, to slightly above normal by week’s end.

The next “problem” arises by next weekend as forecast models sort out what to do with remnant tropical moisture from now TS Beta and an approaching cold front. In this morning’s client video (never posted due to the connectivity issues), we walked through the various solutions. We’ll be “back to normal” from a video perspective late tomorrow and appreciate your patience more than you know.

There’s two windows that are open late next week/ next weekend, including the Deep South and the Ohio Valley dealing with remnant tropical moisture. Given the overall pattern, we favor the southern solution from this distance, but should Beta “dilly dally” in the western Gulf, there will be an opportunity for that next approaching trough to pull that remnant tropical moisture northward into an area desperately needing rainfall. Stay tuned. Interestingly, the European and GFS both agree on the northern trend at 12z.

Notes and Asides: We’ll be back at home base tomorrow night after being down on the Gulf for the past week and will resume normal video production at that point. Despite the quiet times right now, it’ll be interesting to see how things begin to ramp up late next week. Much more later. Have a relaxing Friday evening.
