Saturday will feature unseasonably refreshing conditions as we’ll remain under the influence of an area of low pressure tracking off to our northeast. Look for considerable cloudiness today along with highs around 10° below average. Enjoy it as significant heat looms late next week.
Sunshine will increase for the second half of the weekend and highs will respond- mid 80s after a refreshing start Sunday morning.
High pressure will briefly build in and control our weather through the early part of the new week. An attempt of a thunderstorm complex to impact central Indiana Monday should be thwarted by a drier air mass in place. That said, moisture will increase Tuesday and beyond and a more active regime will return. Multiple thunderstorm complexes (some heavy) will rumble across the Ohio Valley and Mid West Tuesday through Thursday.
While it’ll certainly turn more humid through midweek, the rain and storms will keep temperatures at seasonable levels. All of that changes once to Thursday and Friday as a building ridge of high pressure expands across the Ohio Valley.
This will limit rain chances and potentially offer up the hottest air of the summer. We expect 5-6 days of low-mid 90s for highs and oppressive overnight lows in the lower to middle 70s.
Thankfully, the hot dome will retrograde west and lead to “less hot” and increasingly stormy conditions after the first week of July. An active northwest flow pattern will take hold and provide an active time of things during this period.
The end result would be anomalous heat and a drier pattern, as a whole, as we transition through the early stages of July. Heat to the magnitude of what we experienced last weekend isn’t off the table with such a similar pattern.
Looking ahead, thankfully, one of our more trusted longer range computer models (JMA Weeklies), shows the pattern relaxing as we move into mid-July. The model shows the heat backing west and a more active northwest flow (wetter pattern) returning here…
