Sunshine Returns; Coldest Air Of The Season Awaits…

Highlights:

  • Sunshine returns
  • Coldest air of the season blows into town
  • Wet and cold close to the weekend

Coldest Air Of The Fall On Deck…High pressure is building in and will dominate our midweek weather, including sunshine and unseasonably cool temperatures.  We’ll add a gusty breeze into the mix Thursday afternoon as an early season arctic front approaches.  Once that front passes by Thursday night, a much colder air mass will plunge into the region.  If your travels take you north Friday, snowbelt regions can expect snow showers and embedded squalls as the early season arctic air helps ignite the lake effect machine.  Our first average high of 37° is on December 20th, so we’ll be running well ahead of schedule Friday.  Bundle up!

After a bright and sunny start Saturday, clouds will begin to increase during the afternoon and thicken up overnight as our next storm system approaches.  That storm system will deliver light rain Sunday.  Sunshine returns to kick off the new work week along with slightly below normal temperatures.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″ – 0.50″

Severe Weather Sunday; Much Colder Next Week…

Highlights:

  • Clouds more bark than bite today
  • Stormy setup Sunday
  • Trending colder next week

All Eyes On Sunday…The cold front that passed through the region Thursday night and setup the gorgeous close to the work week is lifting back north this morning as a warm front.  This will result in overcast conditions today, areas of sprinkles or drizzle later in the day, and rising nighttime temperatures.  Scattered thunderstorms will develop across central Indiana late tonight with a warmer and increasingly moist environment.

Sunday will certainly be a day to remain weather-aware.  The overall setup hasn’t changed from what was discussed yesterday with a warm and moist southwesterly air flow in place ahead of an approaching cold front and associated area of low pressure.  Additional ingredients in play suggest we need to monitor the threat of large hail, damaging straight line winds, and potentially tornadoes.  Individual storms (potential super cells) are expected to fire across central and northern portions of the state Sunday afternoon into early evening.  These will be capable of quickly pulsing to severe levels and include potential of large hail, as well as tornadoes (particularly in the vicinity of the warm front which is expected to be draped across north-central parts of the state).  Individual cells are anticipated to “morph” into a squall line Sunday evening, including potential of a quick spin-up tornado, as well as damaging straight line winds.  With a moisture-rich air mass in place (precipitable water values are expected to approach 2″ Sunday evening), locally heavy rainfall is also expected.

All of our “excitement” will come to an end overnight Sunday and we’ll trend much colder (and calmer) during the new work week ahead.  Our next storm system will pass by to our south Tuesday, but may be close enough to spark a light shower across central portions of the state.  Drier and colder conditions build in later in the week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 2.50″

Not Much Sunshine In This Forecast…

Highlights:

  • Milder times
  • Unsettled heading into the weekend
  • Colder next week and remaining unsettled

Vitamin D Needed…While we’re going through a milder stretch of weather between now and the end of the weekend, it’ll come with considerable cloudiness and periods of rain at times.

Most of today will only feature light passing showers and mist, but a clap or two of thunder can be expected tonight as a cold front passes through the state.  The air mass behind the front won’t be particularly cold and a seasonable day is on tap to wrap up our work week Friday.

A warmer southwesterly air flow will return this weekend and this will help boost temperatures to levels as much as 15° above average Sunday.  Scattered showers can be expected Saturday into Sunday and we’re monitoring the potential of a stronger storm Sunday afternoon and evening.  You’ll want to stay tuned for future updates on Sunday’s storm threat.

As we rumble into a new work week, the active and wet pattern will continue and we’ll add a colder feel to the equation, as well.  Monday through Wednesday will feature a “step down” regime: seasonable conditions Monday before turning colder than normal Tuesday and Wednesday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.00″ – 1.50″

A Cold Halloween On Tap…

Highlights:

  • Cold and blustery Halloween
  • Unsettled, milder weather builds in
  • Stronger cold front arrives early next week

Spooky Winds…Northerly breezes are strong and gusty and leading to wind chills in the lower-middle 20s across central Indiana this morning.  Heavier winter coats will be a smart choice out the door!  Otherwise, we’re a state divided from a cloud perspective: the southern half of Indiana will get in on the sunny act much sooner than the northern half of the state.  As we look towards the all-important trick-or-treat weather tonight, anticipate dry conditions, lighter winds, and unseasonably chilly conditions continuing.

Our next storm system will approach Wednesday with showers.  Rain may be mixed with wet snow or sleet Wednesday morning, but with temperatures above freezing, don’t look for any accumulation.  Periods of showers and light rain will continue Thursday into Friday morning.  Heavy rain won’t occur, but it’ll be damp at times.  Saturday is a bit tricky- some solutions keep rain around, but we’re choosing the more “optimistic” approach for the purpose of this forecast update.  Stay tuned.

Saturday will feature considerable cloudiness, slightly cooler air, and breezy conditions before a warmer close to the weekend.  A southwesterly flow will help boost highs into the upper 60s Sunday afternoon ahead of an approaching cold front.  That cold front will slide through here with showers and a couple claps of thunder Monday.  Much colder air returns Monday night into Tuesday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Trace
  • Rainfall: 0.50″ – 1.00″
