Looking At The Week Ahead…

Rainfall of significance is over, and thankfully so.  Many area rainfall totals checked in between 4″ and 7″ and while significant, the overall forward motion of Gordon’s remnants moved much quicker than forecast guidance suggested, ultimately limiting flooding issues from being even worse.

Today we’re left will overcast skies, patchy drizzle at times, gusty winds, and MUCH cooler air.  In fact, the majority of our Sunday will be spent in the 50s.  In case you’re wondering, November 1st is the “average” first day with a high in the 50s- 59° to be exact.

Patchy drizzle is possible through the day, but significant rainfall is over.

Temperatures will remain steady in the upper 50s for the majority of the day.

High pressure will return to open the work week.  We’ll still likely deal with more clouds than sun on Monday, but as high pressure builds directly overhead Tuesday, more in the way of sunshine will return.  Temperatures will be very pleasant through the first half of the work week- lows in the 50s and highs in the 70s.

All eyes will shift to Florence by midweek.  She’ll likely go through a period of significant strengthening on her journey closer to the southeast US coast with a potential landfall along the Carolina coastline Thursday.  There’s still time to watch things unfold, but confidence is increasing on a potential major hurricane making landfall later this week.

Unfortunately, the upper air pattern and lack of a steering current would lead to Florence either stalling out or “meandering” around the mid-Atlantic region for potentially several days…

Meanwhile, back here on the home front, our fall-like early week feel will transition to warmer times as we move into late week and next weekend.  Highs in the mid 80s will return with lows in the mid to upper 60s.

Excessive Rainfall Rates Develop Tonight; Dangerous Flooding Event Evolves…

Serious Flooding Event To Unfold…

Touching base briefly this evening on a significant and serious flood situation that will unfold over the weekend:

Long Stretch Of Wet Weather Ahead…

I. Slow-moving showers and thunderstorms will begin to dissipate this evening and tonight with the loss of daytime heating.  Some area rain gauges have already picked up between 0.50″ and 1″ of rain this afternoon and this will only serve to lay the ground work for further problems moving forward.

II. A growing shield of rain will engulf northern and central parts of the state Friday afternoon.  Initially, this will mostly be of the light to, at times, moderate variety.  Additionally, we’ll notice an increasingly stiff easterly flow as the afternoon and evening wear on.  Temperatures will fall from a high in the middle 70s into the 60s late Friday afternoon and evening.

III. A frontal boundary will remain draped across central parts of the state Saturday while the remnant circulation of what once was Tropical Storm Gordon pushes closer.  As such, rainfall intensity will increase as we move through the day Saturday- particularly by evening into the overnight, on into Sunday morning.  Periods of heavy rain can be expected during this time frame.  Rainfall rates will begin to diminish Sunday PM before moisture exits stage right Sunday evening.

By the time all is said and done, widespread 3″ to 5″ rainfall totals can be expected through the heart of the state, including Indianapolis, but there will be locally heavier totals upwards of 6″ to 7″ in spots.  Flooding, unfortunately, will result.  If you live near water ways please ensure to keep close tabs on water levels and expect rapid rises Saturday into Sunday.  Have a plan in place to escape to higher ground.

IV. After a week of excessive heat and humidity, the coming cooler regime will be welcome by most.  Temperatures most of Saturday and Sunday will remain in the 60s.  At times, “wind chills” (haven’t used that term in a while) will fall into the 50s.

Warmer times will return late next week as ridging re-establishes itself.

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.

Gordon’s Remnants Deliver A Wet Weekend…

This morning, Tropical Storm Gordon continues to churn in the central Gulf of Mexico.  Gordon should make landfall late tonight or very early Wednesday morning along the AL/ MS Gulf Coast as a strong Tropical Storm or minimal Hurricane.

Mostly dry, hot, and humid weather will continue to gain headlines, locally, through midweek.  Thereafter, a combination of ingredients spell for unsettled times late week and a rather wet weekend.

  • Remnant moisture of Gordon will “curl” around the periphery of an upper level ridge to our east
  • A “wavy” frontal boundary will drop south into the Ohio Valley this weekend, entraining the remnant tropical moisture

Eventually, Gordon’s remnants will track into the Northeast Sunday night into Monday and will allow the stationary front to sweep through the Ohio Valley.  This will provide a drier air mass as we open the new work week.

Beforehand, precipitable water values will exceed 2″ at times this weekend, in association with Gordon’s remnants, and this will promote periods of heavy rain.  As things stand now, most widespread heavy rain is expected to arrive Saturday, but it’s a safe bet to plan for wet weather Friday through Sunday.

Widespread 1″ to 2″ rainfall totals are expected this weekend across central Indiana, including locally heavier amounts.
