Wednesday Evening Rambles: Cool, Wet, & Blustery Weekend On Deck…

Gordon’s remnant moisture will claim headlines through the weekend.

I.  A cold front will approach Indiana Thursday and result in increased cloudiness AND a better chance of scattered showers and thunderstorms- especially during the afternoon and evening hours.  Though still warm and humid, temperatures will begin a “step down” process to eventually MUCH cooler readings this weekend.

II.  Unsettled weather will continue Friday into Saturday as the surface front settles south.  As an increasingly blustery easterly flow takes hold across central Indiana, cooler air will continue to “ooze” into the state.  Highs shouldn’t make it out of the 70s Friday with considerable cloudiness and showers around.

III.  Unseasonably cool air will be with us Saturday (most of the afternoon will be spent in the 60s for the majority of central IN, especially north of I-70). A stiff easterly flow and showers will continue.

IV.  The remnant moisture of Gordon will creep closer to the region Saturday PM before setting up shop Saturday night into Sunday evening.  This is the most concerning period for potentially excessive rainfall rates and localized flooding.  We still have time to watch things unfold, but the idea here is that widespread 2″ to 4″ totals are likely with locally heavier totals.  This is “beefed up” from this morning’s call of 2″ to 3″.  Stay tuned, especially if you live near water ways.

V.  Finally, the tropical moisture will surge northeast Sunday night and Monday and a cold front will sweep through the region.  This will set up a much drier and very pleasant period as we open up the new work week.

September Opens Warm Before Mid-Month Changes…

Thursday features updated weekly products from both the JMA (morning) and European (evening).  We’ll update this post tonight once the European Weeklies are in.

The updated JMA Weeklies show a hot open to September as a significant upper ridge takes up residence over the eastern portion of the country.  While the upper Mid West gets in on heavy rain, it’s a rather dry pattern, locally.  Sure we’ll have typical “splash and dash” variety of storms through the Labor Day weekend, but nothing worth cancelling any of your outdoor plans.  In fact, we recommend incorporating a visit (or two) to the pool over the weekend as well above average warmth and humidity dominate.

Week 1

“Transitional period” summarizes this timeframe.  The upper ridge begins to retrograde during Week 2, but it’s still a warmer than average pattern.  It’s a rather dry pattern, as well.

Week 2

Craving a more “fall-ish” regime?  The model says you’re in luck towards the middle of September and would make sense with some of the larger pattern drivers we’re beginning to see behind the scenes.  The ridge axis shifts west and allows a cooler than normal pattern to descend into the central part of the country.
