Heavy Rain (And Thunder Downstate) Arrives For New Year’s Eve…

We’re enjoying pleasant conditions this afternoon with filtered sunshine and temperatures that should top out in the upper 30s to lower 40s later on.  Enjoy it, as a big rain event gets underway for New Year’s Eve.

This afternoon’s visible satellite shows sunshine dominating across the northern half of #INwx.

Clouds will increase tonight and rain won’t be too far behind.  We think wet weather builds into central Indiana before sunrise Monday (likely between 4a to 6a) and periods of heavy rain are still expected late morning into the afternoon and evening hours.

Rain will arrive into the city itself between 4a and 5a Monday. 

We continue to monitor the prospects of a skinny line of strong thunderstorms that may impact southern Indiana Monday afternoon and evening.  If your travels take you south to Louisville for NYE plans, this is something to monitor.  Widespread severe weather isn’t expected, but strong winds are possible if this line materializes.

Timing out prospects for a skinny line of storms to impact southern #INwx Monday afternoon. Best idea as of now will come between 2p and 4p.

This storm system will have a true tropical connection.  Precipitable water values will be quite “juicy” for late December and plenty capable of producing locally heavy totals.  Widespread 1″ to 1.5″ can be expected, but a few area rain gauges will likely see higher amounts.

Colder air will whip in here late tomorrow night and help lingering moisture fall as scattered snow showers New Year’s Day.  More later on the potential of wintry “mischief” later in the week…

Tracking 2 Rain Events; Cold Open to 2019…

Highlights:

  • Wet with a few t-storms
  • Dry weekend
  • Wet then cold to open 2019

Rain Gear Needed…The pattern is transitioning from the predominantly mild stretch of the past couple weeks to one that will turn much colder as we move into January.  In between?  Active times, as we’re tracking two big storm systems between now and NYE.

The initial push of moisture has reached the I-65 corridor as of this forecast issuance early Thursday morning.  Periods of rain will continue through a good chunk of the day and we may even throw in some thunder into the mix later this evening- especially across southern portions of the state.  The other big story today?  Strong and gusty southerly winds.

Rain will end later tonight with dry, blustery, and colder times returning as we close the week.  Highs tomorrow will come predawn before falling through the day.  Dry and seasonable times will continue as we move through the last weekend of 2018.

A new storm system promises a return of wet times as we get set to ring in the new year.  Definitely plan on having the rain gear handy as you head out to those New Year’s Eve parties Monday.  Heavy rain is possible at times.  As the area of low pressure tracks northeast, it’ll swing a cold front through here Monday night and we’ll turn sharply colder with snow showers on New Year’s Day, itself.

Damp Open To The Weekend; Improvements On The Way…

Highlights:

  • Damp at times through Saturday
  • Sunshine returns
  • Looking ahead to Christmas

Rain Gear Needed…A storm system will lift north along the Ohio River between now and Saturday night before crossing the Appalachians and “jumping” to the mid Atlantic coast Sunday into Monday.  This will result in periods of rain today and Saturday.  Heaviest and most concentrated rainfall will remain along and south of the I-70 corridor- especially across southwest IN.  For the majority of us, this won’t be a major rain event.

Improving weather will develop for the 2nd half of the weekend as we introduce at least a little sunshine into the forecast.  That sunshine will set the tone for the new work week, including a nice stretch of weather (by late-December standards) Monday through Wednesday.

A cold front will blow through the state Thursday with a shower possible, followed by colder air to close the work week.

Looking ahead towards Christmas, we still anticipate this to be around the timeframe that we’re transitioning back to colder air.  It’s far too early to get specific around rain or snow, but the transitional pattern does support the idea of more active times.  Stay tuned…

From Storms To Snow; Active Week Ahead…

Our week-ahead outlook is focused on everything from storms to a return of unseasonably cold conditions and snow.  As a strong storm system lifts north into the Great Lakes Sunday, it’ll swing a cold front through the Ohio Valley Sunday night.  This will sweep the briefly milder air out of here and allow much colder air to settle back into the region through the balance of the week ahead.  With the colder air in place, snow chances will return, as well.  First up is a clipper system late week followed by the potential of something “more important” next weekend…

I. Steady rains will come to an end this morning and we’ll replace the soaking rain will widely scattered showers and embedded thunder later this afternoon and evening.  Several dry hours can be expected for the majority of central Indiana beforehand.  While the greatest threat of strong to severe storms will remain to our west in IL, we’ll keep an eye out for the potential of a gusty storm or two- especially west of the I-65 corridor later this evening.

II. Highs today will come tonight (mid-to-upper 50s) ahead of the cold front.  Once the front moves through, colder air will return for the second half of the weekend.  As wrap-around moisture combines with the colder air, light snow showers will develop late Sunday night into Monday morning (shown below).  This won’t be a huge deal.

III. The next item of interest will come from a clipper system Thursday.  This won’t only serve up another round of light snow, but also help to reinforce the unseasonably cold air.  Highs will return to around freezing to close the week with lows in the 20s.

IV. That leads us to what comes next weekend.  While it’s still far too early for any sort of specifics, we’ll simply say to keep a mental note in the back of your mind for the potential of a more disruptive winter event coming out from the southern Plains into the Ohio Valley.  We’ll certainly have to fine tune things and “hone in” as we progress through the upcoming week.  From this distance, prospects range from nothing more than a light snow to a “plowable” storm.  Unlike this weekend’s storm, there will be a limit to how far north next weekend’s storm will be able to track…
