Harvest Forecast: Dry Weather, Cooler Temps Coming After Monday Showers

SHARE

Dry for this weekend. We expect good sunshine and above normal temps but building humidity. South winds should be strong Sunday. The dry warm pattern extends into the start of Monday.

Moisture starts to build up from the south into southern Indiana by Monday midday. The moisture then continues to lift north through the rest of the day. All told, we can see .25”-1” of rain potential over 75% of the state on Monday, with the rain not reaching northern Indiana counties until closer to sunset. The upper end of the range (.5”-1”) will be limited to south central counties

A front moves in from the west for Tuesday, bringing another round of rain and thunderstorms for Tuesday into early Wednesday. This batch of moisture comes with rain totals of an additional .25”-1” with 100% coverage. All moisture is gone by late morning on Wednesday. This puts first half of week rains at a.5”-2” over all of Indiana (See map below). However, this may be all the moisture we see for the entire 10 day window, and perhaps the full 16 day period.

Significantly cooler air comes in behind the front for Wednesday afternoon and stays over the region through Thursday and the first half of Friday. Temps will be below normal, but we expect full sunshine in the wake of the front which will help to moderate the cool air. We stay sunny and dry through net weekend, with temps climbing each day from Friday afternoon through Sunday. Monday the 27th finishes the 10 day window and starts that week with Sunny to partly cloudy skies and additional drying.

Extended Period:

Dry weather rolls on for the first half of the extended 11-16 day window. We see potential for a front sliding through the great lakes and extending southward into Indiana for Thursday the 30th that may have some half to 1” potential, but of course, its very early to make that call. We are dry, but cooler with more clouds behind that front to finish September and start October. We will see well below normal temps for the first weekend in October, the 2nd and 3rd, with some overnight lows in the low 40s.

Weeks 3 & 4:

Week 3 looks to be normal to below normal on precipitation, with likely only 1 good threat of moisture. Week 4 will see a couple threats of rain, and as such may put us in to the normal to wetter than normal camp, especially in southern Indiana. Temps both weeks look to continue the above normal pattern we have seen over most of the month of September. So, we are expecting to shake of those cooler temps that we see in the first weekend of October and continue to keep the overall growing season going easily into mid-October, and likely beyond.
