Looking Ahead To Close March And Open April: Cold Set To Return?

Before we discuss some of what has our attention as we move through the next couple of weeks, check out this cool visible satellite image from this morning.  The snowpack shows up nicely.  It’s also neat to see the high resolution modeling understand where that snow pack is and the associated cooler forecast highs compared to areas south and north that didn’t see the heavy snow Saturday.

As we look ahead, a wet week is in store for the region.  Periods of widespread rain, heavy at times, will come at us in waves:

  • Monday evening-Tuesday
  • Thursday
  • Next weekend, including Easter

When totaled up, widespread 2″ totals can be expected, with locally heavier amounts.

After a brief relaxation in the unseasonably cold regime, well below average temperatures are expected to return as we move through early April.  It’ll feel more like winter than spring through the better part of the first half of the month.

It’s also too early to think about yesterday as the last snow of the season.  Given the early April look, it wouldn’t surprise us if an additional snow event or two came along…

(As a reminder, you can always catch our most up-to-date 7-day forecast in the top left of the homepage).

Heavy, Wet Snow Continues For Most Of Central Indiana…

Right out of the gate, our ongoing snowfall forecast remains unchanged:

Heavy, wet snow will continue through the majority of the day for central Indiana.  At times, banding will produce snowfall rates in excess of 1″ per hour.  On the southern periphery of the snow zone, a mixture of sleet and rain will mix in at times, but as precipitation rates increase, dynamic cooling will keep the predominant precipitation type as snow even on the southern tier.

Despite marginally cold pavement temperatures, the heavy snowfall rate is having no problem accumulating on area roadways and multiple traffic hazards have already been reported this morning, particularly in Boone County.  If you don’t have to travel today, it’s best to remain at home.

As temperatures fall into the lower to middle 20s tonight, refreezing will occur and areas of black ice will develop, especially on untreated, secondary roadways.

The “big dig” will begin in earnest Sunday morning as dry conditions return and the added increasingly strong March sun angle will also help in clean up efforts by afternoon.

By the way, please keep your snow reports and photos coming!

Winter Storm Impacts Central Indiana Saturday…

Today is the proverbial “calm before the storm” as sunny skies give way to increasingly cloudy conditions during the afternoon and evening.  We remain dry today and pleasant, too, with highs around 50 across most central Indiana reporting sites.

Things will begin to change rather quickly during the overnight as rain builds into the state from northwest to southeast, especially after midnight.  As we move through the predawn hours (5a to 7a time frame) we expect rain to transition to wet heavy snow across central parts of the state, including Indianapolis.

The culprit?  Surface low pressure tracking off the lee of the Rockies (today) into the Missouri boot heel (Saturday evening).  Add in a blocking high to the north and this will help provide the cold needed to lead to our winter storm.  From an overall pattern perspective, this “blocky” regime is really what’s been missing for the better part of the past few years as we’ve written in previous posts.  It’s no coincidence that with the blocky regime, central parts of the state are in line for the biggest winter storm in years.  Also of interest is the correlation between late winter blocking patterns and what the next winter can provide, along with other items (another story for another day), but there’s reason to believe we may be on the cusp of returning to winters featuring more snow in the coming 2-3 years.

Back to the present:

Our snowfall forecast includes a widespread swath of 4″ to 8″ amounts through the heart of the state.

We remain very impressed with the prospects of banding which could include snowfall rates of 1″ to 2″ per hour Saturday morning into the afternoon hours.  With such snowfall intensity, even marginally cold surface/ pavement temperatures will allow for slick and hazardous travel across many central Indiana communities Saturday.  Additionally, within localized heavier bands, don’t be surprised for a report or two of thundersnow across central Indiana.  Please share your reports with us as things unfold tomorrow!  Finally, an icy mixture of sleet and freezing rain will also mix with the snow at times along the southern periphery.

Snow should begin to diminish in overall coverage and intensity by Saturday evening- from northwest to southeast.  By that point in time, we’re left with the clean up duties from what will likely be the heaviest snow in a few years for some of us.  The other item to touch on: gusty winds as we still expect 30 MPH + gusts during the day Saturday.

With all of that said, let’s remember March snow events always offer “surprises-” no matter how much we try to eliminate those surprises.  There will be winners and losers with this event in the snow department.

Sunday will feature a return of dry conditions, as well as a return of the sunshine!

Heavy Snow Targets Southern; Eastern Parts Of The State…

Snow will continue to expand across southern and eastern Indiana as we progress through the evening hours.    Additionally, snowfall intensity will increase overall into the overnight hours across southeast Indiana.

Radar at 7:15p shows heavy snow across southern Indiana.

Our latest snowfall forecast is vastly unchanged from this morning, with the exception of expanding the 3″ to 6″ area a bit further west.  Within this zone there will be a few reports of 8″ to 10″ before things wind down Wednesday afternoon.

Snow will continue to fall through the overnight and into Wednesday morning before eventually diminishing across eastern parts of the state early Wednesday afternoon.  At times, snow will be heavy and we continue to expect tough travel tonight into the daytime Wednesday across southern and eastern Indiana.  When shoveling and cleaning things up Wednesday, remember this snow event will take on a heavy, wet characteristic.

After a mostly dry and quiet time of things Wednesday afternoon and Thursday, our next storm system will approach Friday evening.  This event will also have a wintry flavor to it and the potential is present for additional ice and snow accumulation Friday night into Saturday.  If you have travel plans this weekend we recommend keeping close tabs on the forecast!

As mentioned in this morning’s video update, the longer range pattern is one that continues to suggest colder than average temperatures will rule the day.  Until we can shake that negative NAO we don’t anticipate any major improvements in this pattern.  Remember, we’re only the messenger… 🙂
