Week-Ahead Outlook; Additional Early-May Chatter…

We may only have a few days left in April, but widespread frost is being reported across north-central into east-central Indiana (yet again) with most across the region in the lower to middle 30s this morning.

Sunshine will dominate to start our Monday before mid and high level clouds increase this afternoon into the evening hours. Eventually these clouds will produce scattered showers by evening (targeting a 6p-7p arrival into central Indiana).

Initially these showers should be very light and scattered in nature, but heavier rain and embedded thunder will develop during the overnight hours.

Showers and embedded thunder will exit Tuesday morning and most of the day will be rain-free, including a return of sunshine. This will help boost high temperatures into the lower 70s Tuesday! Unfortunately, an approaching cold front will lead to a return of storms Tuesday evening and much cooler air by midweek. A few of the storms could reach strong to severe status Tuesday night with the primary concern being damaging wind and large hail.

Showers and thunderstorms will return Tuesday night. A few of these may be strong to severe.

The cold front will sweep through the area Wednesday followed by a cut off upper low “wobbling” around the Ohio Valley Wednesday night into Thursday. This will lead to windy, showery, and much cooler conditions for midweek. In fact, temperatures Thursday will likely fall into the 40s during the daytime.

By the time all is said and done, we think most central Indiana communities can expect between 1.25″ and 1.75″ of rain, but there will be some locally heavier amounts in excess of 2″.

Major improvements are ahead as we get set to close the work week. High pressure will briefly build into the area, supplying plentiful sunshine and warmer conditions Friday.

The warmth will persist into the weekend and this morning’s video update dives into the longer range.

Much Needed Time To Dry Out…

It was another wet and stormy weekend across central Indiana. Heaviest rain fell north of the city, itself, with several areas recording over 3″.

March, as a whole, has been wet. Officially, Indianapolis is running 1.36″ above average, month-to-date.

Thankfully, the upcoming week will feature much calmer and quieter conditions. In fact, we should make it through the entire work week without a drop of precipitation. A system will pass well to the south of central Indiana Tuesday.

Drier than average conditions will prevail this week, giving our immediate area much needed time to let saturated soils slowly soak up that water from the weekend.

The next opportunity for showers and thunderstorms will arrive on the scene Saturday. From this distance, this looks to be a rather moisture starved front, but we’ll keep close eyes on things as we get closer to the weekend.

Reviewing Saturday’s Snow And Looking Ahead To Another Busy Week…

Snow moved in during the predawn hours Saturday across north-central Indiana before encompassing more of central Indiana as the morning progressed. By mid-late morning, an incredibly intense band (2″+/ hour snowfall rates) set-up shop just north of Indianapolis. This was a byproduct of strong frontogenesis and dynamic cooling. Speaking of frontogenesis, if interested, here’s a fantastic article that can explain things further.

The end result was an “overachieving” wet snow event across north-central Indiana, including as far south as the northern Indianapolis ‘burbs. Sleet made it as far south as Greenwood before precipitation ended Saturday evening.

While the placement of our accumulating snow zone was a good one, amounts of 4″ to 5″ were reported throughout the southern half of this 1″ to 2″ forecast zone. This morning’s snowfall analysis shows the narrow, but moderate stripe of wet snow through the state:

As the sun rises and clouds begin to depart, that snowpack is showing up on this morning’s visible satellite image.

Officially, Indianapolis recorded 1.2″ Saturday, but as noted above, areas just north received as much as 4″ to 5″. With that increasing March sunshine today, snow will be all but a distant memory by later this afternoon. The average high for March 15th is in the lower 50s. Most will be 5° to 7° colder than that today with mid 40s for most.

As we turn the page and look ahead to what the remainder of the week will provide, a weak cold front will sweep through the Ohio Valley Monday night and Tuesday. This will be a moisture-starved frontal passage with only scattered, light showers anticipated tomorrow evening/ early Tuesday.

Things then turn much more unsettled as we head into the second half of the week. An initial wave of moisture will result in a period of moderate to heavy rain Wednesday. This will be followed up with a round of thunderstorms Thursday PM into early Friday morning. Some of these storms may reach strong to severe levels and will require us to continue to closely monitor things throughout the week.

Widespread 2″ to 2.5″+ rainfall amounts can be expected by the time everything winds down Friday afternoon. Most of that will fall Wednesday and Thursday night/ Friday morning.

We’ll dry out next weekend, but shift to a much colder time of things (lows in the 20s and highs in the 40s). This will come as a rather rude shock after highs Thursday flirt with the 65° to 70° mark.

Burst Of Snow This Afternoon; Storms And “Rumors” Of Storms This Upcoming Week…

The day is starting off on a cold note with some fog and low clouds around, but at least we’re dry (for now). That will begin to change here in a few hours as a burst of snow moves into the city around lunchtime. A brief period of moderate to heavy snow may whiten the ground just north of the city before a transition to a cold rain for the better part of the afternoon.

Further north, cold air will hang on longer and a more significant period of snow is expected through the afternoon and early evening. In fact, periods of heavy snow can be expected, including snowfall rates up to 1″ per hour at times. If you have travel plans to places such as Ft. Wayne, South Bend, or Logansport, we’d recommend preparing for slick travel and snow covered roads can be expected. This will be a wet and heavy snow. Pavement impacts will require salting and plowing across the northern 1/3 of the state this afternoon into the evening.

Here’s our snowfall forecast today:

The attention will then shift to a period of moderate to heavy rain through the evening and into the overnight across the I-70 corridor. By the time all is said and done Monday morning, widespread 1″ to 1.5″ is expected with the passage of this storm system. Good news? Most of the rain should be south of our area by the morning rush Monday.

High pressure will then settle into the Ohio Valley as we move into Monday evening and Tuesday, allowing a briefly quieter period of weather to arrive on the scene.

By this time, however, all eyes will shift to the southwest and our next storm system that should be brewing. While models differ on the specifics with this storm, the overall upper pattern suggests we need to remain on our toes with respect for the potential of additional winter weather stretching from the mid-MS Valley Wednesday, Ohio Valley Wednesday night into Thursday, and interior Northeast Thursday into Thursday night. A brief, but potent shot of arctic air would follow to close the work week- especially if we can get some snow down.

Should snow get laid down with this system across the OHV region, a cold arctic high would be capable of sending temperatures into the single digits to close the work week.

Stay tuned…
