How did you enjoy the rare late season snowfall? Rhetorical question I’m sure, but meteorologically speaking it was quite a feat. There are many stats to chew on, but we’ll begin with a first for the city of Indianapolis that actually occurred Monday.
According to the National Weather Service in Indianapolis, yesterday was the only date on record (dating back to 1871) in April where the city had a high >=70 degrees and measurable snow in one day. The only other day remotely close with April 7, 1972 with a high of 67 and .2″ of snowfall.
There were several 1″ snowfall reports throughout central Indiana, but it was mostly confined to grassy/elevated areas.
The .30″ at NWS Indianapolis was only the 4th measurable snowfall on or after April 15th since 1975. This pushes the snow year (July 1-June 30) to nearly 56″ which is good for third snowiest on record behind the legendary winters of 1977-78 and 1981-82.
Now the focus is on the January-like air mass claiming real estate across the Ohio Valley.
To say today is unseasonably cold is an understatement. Afternoon highs will be colder than the average low (42) for this time of year. The record low maximum for this date in Indianapolis (40° in 1928) will be tied or possibly broken. Anyway you slice it today feels more like January.
The brisk northwest wind that pushed lake effect into central Indiana will gradually break down. As a result snow showers and cloud cover should diminish by 5-6pm, with the exception of far eastern Indiana.
Our cold day, followed by a clearing sky and light wind, sets the stage for a hard frost/freeze tonight… with lows dropping well into the 20s. We’re urging people to protect any sensitive plants from what will be damaging cold.
After a frosty start Wednesday temperatures will return to the 50s, but still a good 10° below normal. Highs return to the 60s Thursday in what will likely be the best the day of the week, before rain chances return Friday.
There remains some uncertainty in the long range regarding how quickly the Friday disturbance departs. For now, the holiday weekend looks mostly dry and pleasant with highs climbing back into the 60s.
Here comes the cold. The transition from summer-ish 70s this past weekend and while you were sleeping, to winter-like lows in the 20s tonight will be accompanied by a period of wet snow in central Indiana.
Periods of gusty rain showers continue into the afternoon as temperatures slide into the lower/middle 40s by 5pm behind the passage of a cold front at midday today.
Colder air aloft catches up with residual moisture behind the front, and we’re expecting a transition from rain to wet snow between the hours of 9pm and 12am… with potential for an axis of moderate/heavy snow to pivot through central Indiana between 12am and 5am.
The ground will likely be warm enough to melt most snow, however some areas may see a minor slushy/grassy accumulation where it snows hard enough to overcome that warm layer. Latest modeling suggests the eastern half of the state has the best “potential” for this slushy accumulation. Snow in April is not totally unusual with Indianapolis averaging .20″ for the month. But the last “measurable” April snow in the city was 2001… and that streak may end tonight. The jolting shot of cold air may become the bigger story.
Though not record-breaking , lows tonight and Wednesday morning will be in the 20s with a widespread frost/hard freeze Wednesday morning. The record low “maximum” is 40 degrees Tuesday and will be rivaled in many areas.
This will be a 36 hour window of chilly air before sun and warmer temps return after Wednesday morning. Thursday is our “pick of the week” with sunshine and mid-60s… and this precedes our next round of rain that arrives Friday afternoon and evening. Have a great day!
We’re capping off the warmest weekend of the year with filtered sun and highs in the 70s. The shelf life on dry weather is set to expire after dark, as a band of rain and gusty storms arrives around or shortly after midnight in western Indiana. This wave of of storms will move across central Indiana between 1-4am, with perhaps another wave arriving toward sunrise Monday.
Though we’re not anticipating widespread severe weather, a localized severe gust (>= 58mph) is a possibility. Balmy air remains in place overnight and you’ll wake up to temperatures in the 60s.
However, the passage of a cold front late morning/early afternoon opens the gates to unseasonably cold air. Expect temperatures in the upper 30s/lower 40s by 5pm and rain will mix with and change to snow Monday night into pre-dawn Tuesday morning.
Accumulation is not expected, but this will certainly be a jolt to the system after this weekend. Lows Tuesday morning will be in the 20s and highs will struggle to return to the 40s. A widespread frost/freeze appears likely Wednesday morning as clouds clear and the wind diminishes.
But this also marks a turning point, as the air mass quickly modifies and temperatures return to normal Thursday. Have a great evening.
So how did you enjoy arguably the best weather day of 2014 thus far? After a long, cold and snowy winter… sun and upper 70s is just what the doctor ordered! You can’t write a better weather script for the inaugural home match of the Indy Eleven this evening at Carroll Stadium. Enjoy and please scream loud and proud for me too!
Courtesy of steady southwest wind, we’re in store for a repeat temperature performance Sunday. Though the sky may not be as bright tomorrow due to cloud debris from upstream thunderstorms.
That balmy breeze will keep temperatures near 60 degrees for lows tonight. That’s a good 20 degrees above normal. Highs return to the upper 70s Sunday before a new batch of rain and storms arrive late tomorrow night into Monday morning.
Monday will be a day of transition, from spring temperatures in the 60s to the upper 30s Monday afternoon. Don’t’ be surprised to see some wet snowflakes mixing in with the rain as colder air aloft pivots across central Indiana.
Highs Tuesday will struggle into the mid-40s before air mass modification kicks in mid-week and we get back to normal Thursday. Have a great evening.
Welcome to what should become the warmest day of 2014 thus far, and central Indiana’s warmest day since mid-October. A steady southwest wind and ample sun will be enough to overcome some passing clouds… as high temperatures make their charge toward 70 degrees.
Latest hi-res modeling suggests breezy, mild and mostly dry conditions at the time of the Indianapolis Indians’ home opener first pitch at 7:05pm. However, we’re recommending that fans attending the game tonight take ponchos and necessary rain gear as rain and thunder chances increase by the 7th inning stretch.
Rain and embedded storms will be most likely “between” the hours of 9pm and 2am, and gradually diminish overnight from northwest to southeast as a front settles along the Ohio River.
North side of the boundary tomorrow will lead dry conditions for the majority of the viewing area. But the front will close enough to areas south of I-70 to warrant a “chance” of showers.
This front eventually returns northward Saturday, and perhaps may trigger very spotty showers… but a majority of the weekend may prove to be dry and the focus shifts on unseasonably mild highs in the 70s both Saturday and Sunday.
Higher rain/thunder chances return Sunday night into Monday with a return to cooler air the first half of next week. Have a great day!
What a tranquil day in central Indiana, and certainly worthy of the “pick of the week” nomination. Sunshine, fair weather clouds and highs in the 60s are a welcome sight.
Unfortunately the high pollen count is not. If you suffer from allergies please note the pollen level will remain high in central Indiana into the weekend.
If you like it warmer than Thursday is just for you.
Highs tomorrow will near or climb above 70 degrees for the first time since mid-October. Much of Thursday will be full of sunshine, but an approaching cool front will trigger a line of rain with embedded thunder tomorrow evening.
It’s subject to change, but early call for arrival time in the Indianapolis metro is between 6pm and 8pm. We don’t anticipate severe weather, but a rain or lightning delay is possible if you plan to attend the Indianapolis Indians home opener.
The aforementioned front should settle southward across the Ohio River by Friday morning. As a result we’re only expecting isolated rain chances for most Friday. However, if the front slows enough higher rain chances may be needed. Mild conditions prevail heading into the weekend with highs in the 70s both days. A slower arrival time on the next front to impact the region will lead to a good portion of Sunday being dry.
Rain and storms become widespread by 12am Monday, and another inch of rain is very possible along with sharply colder air in the 30s Monday afternoon. Have a great evening.
We’re closing out the weekend in style. Sunshine and pleasant temperatures in the middle to upper 50s. Hopefully you had a chance to enjoy the dry time this weekend, with another soaking rain arriving by sunrise Monday.
Though this system won’t deliver three and four inch rain totals… half-inch to near one inch amounts are not welcomed news with many rivers and creeks remaining high. Rain combined with a brisk northeast wind and highs in the middle 40s makes for an unpleasant day to be outdoors.
Steady rain begins to depart Monday night, and Tuesday should start dry. But the combination of cold air aloft, an upper level disturbance and surface heating into the middle 50s will aid in the development of scattered storms Tuesday afternoon. Some of these storms may produce hail, and perhaps nearing severe levels. Stay tuned for updates on this feature.
Otherwise the focus quickly shifts to the well advertised arrival of the warmest air of the year. We’re to mostly sunny conditions Wednesday and highs make a run at 60 degrees.
Thursday southwesterly wind strengthens and transports very mild air into central Indiana… with highs possibly climbing into the 70s for the first time since mid-October!
An approaching cool front may have just enough moisture to trigger scattered showers late Thursday night into Friday. At this time confidence is low on this happening, but we’ll monitor for changes. Mild air looks to hang around into next weekend. Have a great evening – Sean Ash
It’s been an impressively wet start to the month April. Only four days deep and Indianapolis is only 1.31″ below the monthly average rainfall. You can definitely feel the difference in air behind the passage of a cold front from earlier today. Temperatures are a good 15 to 20 degrees colder and the gusty wind makes it “feel” like the upper 20s to lower 30s.
Some locations have already eclipsed the nearly 4″ monthly average, which is why Flood Warnings continue at this hour. We’ll be rain-free until Monday, but the trade off will brisk conditions this evening and a chilly night ahead. You can definitely feel the difference in air behind the passage of a cold front from earlier today. Temperatures are a good 15 to 20 degrees colder and the gusty wind makes it “feel” like the mid to upper 20s.
Clouds departing tonight will take away our “insulator” and allow overnight lows to drop to near 30 degrees by sunrise Saturday. Thankfully we’ll see plenty of sun tomorrow and most of the weekend… and with a calmer wind too.
After the cold start, highs jump into the lower 50s Saturday and near 60 Sunday. We’re recommending you take care of any yard work or outdoor plans this weekend, with a wet/windy day setting up Monday.
A strengthening low pressure system from the south brings widespread rain, windy conditions and keeps temperatures in the 40s Monday.
This system quickly departs and the focus shifts to potentially our warmest air the year later next week… as highs make a run at 70 degrees and higher next Thursday.
Have a great weekend – Sean Ash
