Saturday Snow…

There’s just something special about seeing the first flakes of the season.  While this initial wintry event won’t be a big deal accumulation-wise for central IN, a few inches of snow will be likely across northern portions of the state Saturday.  Here’s our initial snowfall forecast, brought to you by the IndySportsReport.com.112115SnowForecast1stLookThe next two days will be easy and rather “boring” as far as the weather goes.  Look for more in the way of sunshine today before clouds begin increasing as Friday progresses into evening.  The initial push of moisture should reach central IN Friday night (as rain).  Rain will then transition to snow showers before ending across central IN Saturday morning into the early afternoon.  Farther north, look for a quicker transition to snow where we forecast a 2″-4″ type accumulation event for places along and north of a Newton County to De Kalb County line.  This is an early call and may require some fine tuning as we go through the next 24 hours.  We’re about as confident as we can be with the forecast at this juncture, but do note a couple differences with the track of the low between the various models we use.

Here’s the track set-up:

A wave of low pressure will “scoot” east, northeast Friday into Saturday as highlighted here by the fine folks at Weatherbell.com.

FriEvening

FriNight

SaturdayMorningEnough of a south wind will keep us just warm enough to provide mainly a rain event for central and southern portions of the state.  Colder air will be deeper and more entrenched across northern IN where this should be a mainly snow event.  As the winds quickly whip around to the NW Saturday morning, temperatures will plummet and lingering moisture will quickly transition to snow for all of the state.

Behind the rain-to-snow event Saturday morning, the coldest air of the season will plunge into the state.  Lows Sunday morning will fall into the teens for many of central IN, especially if we can lay down a snow cover up north.  Throw in a gusty NW wind and wind chill values in the single digits are a good bet.

Can things still change with the track of this storm?  Absolutely.  While we feel as confident as we can be at this stage in the game, we do note a couple differences with the track of this area of low pressure (as mentioned above) between the various computer models we use.  We’ll continue to keep a close eye on things.  One other item of note is the relatively warm surface temperatures and that will cut back on accumulations across not only central, but northern parts of the state, as well.  Much more later!

Wet Today; Colder Air Coming…

Screen Shot 2015-11-18 at 7.15.50 AMHighlights:

  • Rain today
  • Breezy and turning cooler
  • Secondary push of early season arctic air

Our big autumn storm system is swirling through the central Plains this morning.  It’ll begin to pick up forward momentum and head northeast over the next 24 hours.

We’re dealing with an impressive fetch of moisture (w/ a Gulf of Mexico connection) this morning and that’ll help feed embedded heavy downpours this morning into the early afternoon.  Here’s a time stamp of forecast radar images, courtesy of Weatherbell.com.

11aSimRadar

3pSimRadarAs mentioned above, with a GOM connection, embedded heavy rain will dampen your Wednesday activities.  On average, we’ll add an additional half inch to inch of rain today (that’s on top of what we saw Monday and Tuesday).

RaintotalsOnce to tomorrow all eyes will be on our next storm system that will eventually help pull down the season’s first blast of arctic air.  Ahead of the cold surge, expect light rain to end as light snow across central IN Saturday.  This won’t be a big deal from an accumulation perspective, but it’s always exciting seeing the first snow flakes of the season.  Further north, across our northern tier of counties, a couple inches of snow will be possible.

SatPMStormTrackWe’re also keeping a close eye on Thanksgiving’s weather.  While still a bit early to be specific, initial thoughts suggest we’re dealing with a storm on, or just on either side of Thanksgiving, that will provide rain to begin, but we caution that another surge of early season arctic air looks to pour in behind that storm system and potentially set the stage for a more impactful winter event to open December.  More on that in the days ahead…

Couple Storms To Watch And Much Colder Air…

Screen Shot 2015-11-17 at 7.30.17 AMHighlights:

  • Periods of rain
  • Turning cooler
  • Next storm offers up wintry precipitation for parts of the state
  • Early arctic blast

Periods of rain will continue into the mid to late afternoon across central IN as “wave 2” of our current storm system moves through.  We’ve added a couple simulated radar images below, courtesy of Weatherbell.com.

9aFuture

2pFutureThis is all in association with a significant autumn storm system that’s been responsible for delivering hefty snows across the Rockies, blizzard conditions across the High Plains, and severe weather across the central and southern Plains.  This storm will lift northeast over the next 24-36 hours.

TuePM

WedPMA third, and final, wave of moisture will push through the state Wednesday, in a weakened state from what our friends to the west will experience (where another round of severe is expected today and tonight).  This is what the radar may look like mid-morning-ish Wednesday.

10aWedFutureWhen all is totaled up from rain that began Monday afternoon and ends Wednesday afternoon, many locales will pick up 1.5″-2″ of needed rainfall.  While significant, those numbers are lower than what originally model data implied, but we’ll take what we can get to push closer to average for November rainfall.

All eyes will then shift to our second storm system that will arrive over the weekend.  There are still more questions than answers in regards to track of this next “wave” of low pressure, but with much colder air in place and pouring in behind the system, snow will fly across northern IN.  As of now we forecast the majority of this event to fall in a liquid form across central IN, but even here precipitation may end as light snow showers the way things stand now.  Stay tuned as we continue to fine tune the track. Regardless, much colder air will be with us to end the period.

I Like It Euro…

We posted our annual IndyWx.com Winter Outlook last Saturday.  If you haven’t read it yet, or want some good material to put you to sleep :-), feel free to click here.

Tonight we see the latest seasonal long range European model shifting the Nino to more of a central-based El Nino as we rumble deeper and deeper into winter.  This is another indicator that mid and late winter could be cold.  In any event, here you go:

Nov, Dec, Jan

Screen Shot 2015-10-19 at 11.45.28 PMJan, Feb, March

Screen Shot 2015-10-19 at 11.45.39 PMThere sure have been a lot of comparisons of this El Nino to that of ’97-’98.  That’s fine in talking strength, but the overall SST profile both in the Pacific AND Atlantic is vastly different.

Hmmm…time to go dream about snow storms.  – Combine a positive PDO with a central-based El Nino and there could very well be plenty of wintry “fun and games” in the months ahead.
