Forecast Period: 09.22.19 through 09.29.19
7-Day Precipitation: Below average precipitation is expected through the period.
7-Day Temperatures: Well above average temperatures are expected through the period.
Severe Weather: Organized severe weather isn’t expected through the forecast period.
Frost/ Freeze: The growing season will come to an end this week across the central Rockies (frost and freeze warnings are up) and eventually across the Bitterroot range as lows fall into the mid and upper 20s by late week.
Drought Monitor: The latest drought monitor shows widespread dryness across the central and southern portions of the Ohio Valley, extending north and northwest into IA and MI. A good chunk of these dry/ droughty areas from MO, IA, and IL will be wiped out by Thursday’s update as beneficial soaking rains fall on this area today from the remnants of Imelda and a passing cold front.
Summary: A cold front and remnant moisture from Imelda will lead to better rain chances across central Indiana this evening into early Monday morning. With that said, the widespread soaking rains our friends just west of our area are receiving this morning will diminish as they move into central Indiana tonight. While there will be a couple of exceptions (with heavier rainfall totals), most central Indiana rain gauges will likely pick up between 0.25″ and 0.50″ tonight. Thereafter, temperatures will trend cooler (more seasonable) for the early and middle part of the work week before an expansive ridge engulfs the eastern portion of the country late week into Week 2. This will promote not only well above average warmth, but in some cases rival records.
A series of cold fronts will sweep through the Ohio Valley over the upcoming couple of weeks and each will likely feature progressively cooler conditions.
At the surface, we see the cool pattern taking hold into not only the short-term, but the 10-15 day range, as well.
