Highlights:
- Dry, warm close to the work week
- Warm weekend
- Much cooler air awaits
Summer Feel Gives Way To An Autumn Chill…A backdoor cold front will press into central IN over the weekend and will serve as a focal point for increased clouds at times (northern portions of the state today and more of central IN Saturday). While an isolated to widely scattered shower is possible with this front, most will remain rain-free straight through the weekend. Temperatures will remain well above normal across the region.
A stronger cold front will march towards the area to open the work week. Showers and embedded thunder will accompany the frontal boundary as it pushes through the region. We’ll then note a marked NW wind shift by evening and that will help usher in a true push of fall air. A stretch of mornings with lows in the 40s and highs in the 60s during the day will take us through mid week. Those cooler readings will really being to ignite the color change across central IN.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″
A “backdoor” cold front will approach the region from the northeast late in the weekend, but won’t have enough “umph” to push the drier, cooler air our friends across the northeast and mid Atlantic will enjoy our way.
The evolution of the pattern from an unseasonably warm, dry regime to a much cooler, autumnal feel will, undoubtedly, feature showers and thunderstorms as we transition. Modeling continues to waffle back and forth in regards to rainfall totals. As of now, we’ll highlight Monday-Wednesday with increased rain chances.
Thereafter, we turn MUCH cooler. Data suggests Tuesday-Friday features temperatures much more like we’d expect for late September. Lows in the 45-50 degree range, along with highs between 65-70 can be expected.
The warmth continues in the days ahead, but we’re going to run much drier, overall, as strong ridging remains the dominant factor through late week.
The past (90) days have featured hefty rains across the Mid West.
Late season heat will grip most of the east over the upcoming (7) days. Note those population areas (nearly 90% of the lower 48) to experience at, or above, 80 degree heat between now and next Tuesday. Even areas into the Lakes and New England get in on the late summer feel.
In the shorter term, an isolated shower is possible this evening, but most should remain dry as the air is very dry across the region.
The upper air pattern features strong ridging over the central and east over the upcoming several days. A cold front and associated trough will deliver cooler air by the early to middle part of next week.
In between the warmth and pending cooler, more fall-like, air will be a round of scattered showers and thunderstorms early next week. Modeling differs on precipitation amounts, but, as of now, heavy rains aren’t looking likely.
As mentioned, early to middle parts of next week should feature temperatures much closer to where we should be this time of year, if not a few degrees below average.
