The Beat Goes On (For Now)…

The unseasonable warmth won’t last, at least not to this magnitude, but an overall warmer than average pattern should persist over the upcoming couple of weeks.

The teleconnections (positive AO, positive EPO, negative PNA) are aligned in a manner that will drive the ‘mean’ ridge position across the eastern portion of the country.

Subsequently, the warmth, relative to normal, remains locked in over the East through mid month. Note how similar the GEFS and EPS are between Week 1 and Week 2.

Though we will cool off behind the passage of a cold front next week, we’re still running above normal into Week 2.

We’re not ready to throw in the towel on the idea we could be looking at a more wholesale pattern shift late month. The MJO supports that idea. Note Phase 2 this time of year favors the chill to settle into the East.

It’ll be an interesting test case in what otherwise looks to be a mild to much milder than normal (and quiet) pattern.

Active Close To October…

Our annual Winter Outlook will debut Sunday morning, November 1st.

A frontal boundary will remain draped over the Ohio Valley through midweek before lifting north as a warm front late week. As we gear up for the weekend, this same front will barrel southeast as a cold front. While it won’t rain the entire time, the end result will be quite an active week with periods of rain (at times heavy).

Looking ahead, it appears as if best chances for concentrated rain will come Tuesday night into Wednesday morning, Friday evening, and Sunday into next Monday. This is a hectic pattern and we’ll fine tune if needed. Widespread 1”-2” rain totals (locally heavier amounts) can be expected for the northern half of the state by early next week with 2”-3” totals (again, locally heavier) across the southern half of Indiana (generally along and south of I-70).

As the PNA pops positive, a colder than normal airmass, and coldest so far this autumn, will settle southeast prior to Halloween. This is the type of pattern that should generate a multi day hard freeze with temperatures falling deep into the 20s early morning.
