Turning Colder After A Wet Open To The Week…

screen-shot-2017-01-01-at-7-25-02-pmHighlights:

  • Unsettled open to the week
  • Turning colder Tuesday
  • Couple snow chances, but low confidence

Wet Open To The Week…Clouds waited to increase until after sunset Sunday and the more than expected sunshine led to a downright beauty of a kickoff to 2017, complete with mild temperatures.  Unfortunately, those pleasant conditions won’t last as we deal with increasing coverage of showers and perhaps a thunderstorm Monday.  Rain coverage appears greatest during the evening into the nighttime hours.

An arctic cold front will sweep through the state Tuesday afternoon and lead to a dramatic temperature plunge for the rest of the week.  Showers Tuesday will end as a touch of wet snow before precipitation moves out.

Forecast models are still struggling with handling Pacific energy for mid and late week.  This is leading to a lower than normal confidence level with two potential systems Thursday and again Saturday.  For now, we’re eyeing the threat of light snow with both and believe modeling will come around to more of a weather maker once time draws closer.  Stay tuned.  Cold weather remains as we progress through next weekend.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 1″ – 3″
  • Rainfall: 0.50″ – 1.00″

Busy 7-Day To Usher In 2017…

screen-shot-2016-12-30-at-7-18-25-pmHighlights:

  • Raw New Year’s Eve
  • Briefly milder Monday with showers
  • Snow prospects mid week

Busy Times…Clouds will increase late tonight and give way to showers during the daytime New Year’s Eve.  Most of this shower activity will be light, but you’ll want to carry the rain gear with you as you leave for New Year’s Eve parties and celebrations throughout central IN.  Once to the nighttime hours, showers should diminish and most of the nighttime should feature rain-free conditions, along with colder temperatures.

New Year’s Day may start out with some sunshine, but clouds will increase through the day and drizzle or light rain is possible by evening.  Low pressure will track northeast from the central Plains into the upper Mid West Monday.  This will place Indiana in a relatively warm southwest flow.  Periods of showers can be expected through the day, along with breezy conditions.  An accompanying cold front will sweep through the state early Tuesday morning and shut rain chances off, shift winds to the northwest, and lead to falling temperatures.

Wednesday will be a day in between storm systems.  Cold high pressure will settle into the Ohio Valley and supply unseasonably chilly temperatures, but with sunshine.

Our next storm system will approach Thursday.  Clouds will increase Wednesday night and give way to an expanding snow shield during the day Thursday.  We still have a few days to look at things, but from this distance, the potential is present for an impactful wintry event across a widespread portion of the Ohio Valley, including central Indiana.  Stay tuned.  Fresh arctic air will move in to put a close on yet another short work week.

Upcoming 7-Day Precipitation Forecast:

Snowfall: 1″ – 3″

Rainfall:  0.75″ – 1.25″

Snow Squalls Thursday Evening; Active Pattern…

screen-shot-2016-12-28-at-10-18-11-amHighlights:

  • Showers this evening
  • Snow squalls develop Thursday evening
  • Active weather pattern into next week

Early Sun Gives Way To Showers By Evening…A sunny, frosty start to the day will give way to an increasingly cloudy sky by afternoon and scattered showers by evening.  Latest data suggests showers arrive into central Indiana by 6-7p.  This won’t be a significant rain maker, but just enough to create damp conditions as we put a wrap on Wednesday.

A reinforcing push of cold air will blow through Thursday evening.  With enough instability and upper air energy, scattered heavy snow squalls will become likely across the region by afternoon into the evening.  This won’t be a “uniform” snow event, but some localized accumulation (thinking a coating to less than 1″ in spots), along with dramatic drops in visibility can be expected by evening as these scattered snow squalls increase in coverage.  Additionally, winds will gust to 40 MPH and will aid in creating hazardous travel at times tomorrow PM.  Scattered snow showers will continue into the day Friday.

Moving forward, we continue to eye the potential of a light wintry mix arriving on New Year’s Eve.  As of now, this doesn’t appear to be a big deal, but we’ll monitor things as new data streams in.  “Light” is the key word for now and temperatures look marginal, at best, for wintry issues.

As we rumble into next week, model consistency and overall agreement is rather non-existent.  This leads to a lower than normal confidence on the important details in regards to the early week storm system (and looking forward, towards a second storm coming along just beyond the current forecast period).  For now we’ll go with showers Monday afternoon paving way to more widespread rain Tuesday.  As colder air rushes in Tuesday night, precipitation will change to snow along with a strengthening northwest wind and an increasingly bitter feel by the middle of next week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 1″ – 2″
  • Rainfall: 0.50″ – 1.00″

Unseasonably Warm; Wet Day After Christmas…

screen-shot-2016-12-26-at-8-33-12-amHighlights:

  • Unseasonably warm today
  • Showers and perhaps a t-storm by lunchtime
  • Turning more seasonable later this week

Wet At Times Today…A cold front will push across the state later this afternoon.  Ahead of the front, a warm southwesterly air flow will lead to a spring-like feel on this day after Christmas.  Coverage of showers will increase by late morning and around lunchtime, including the possibility of an embedded thunderstorm.  Once the front sweeps through the region, our winds will flip to the northwest and result in a cooler feel as early as tonight.  Tuesday will feature much more seasonable conditions.

Reinforcing chilly air will blow into town Thursday afternoon and with enough upper level energy around, we’ll mention scattered snow showers in our forecast.  Colder weather will be with us to close the week and head into New Year’s weekend.

Speaking of New Year’s, we still eye a storm system around New Year’s Eve.  Confidence is low in the overall set-up in regards to storm track and timing and fine tuning will be required.  For now, we’ll simply go with a developing light wintry mix Saturday and “sure up” the details later this week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting
  • Rainfall: 0.50″ – 0.75″

Merry Christmas Eve…

screen-shot-2016-12-24-at-8-03-42-amHighlights:

  • Areas of fog
  • Rising temperatures Christmas night
  • Turning more seasonable next week

Ah, Christmas Eve…From our home to yours, we wish you a very merry Christmas and a blessed holiday season.  It’s hard to believe Christmas Eve is upon us.  Despite areas of fog and an overcast, chilly day, weather really won’t present much of a challenge, locally, for travelers or last-minute shoppers (surely we don’t have any of those in central IN).  😉  Rudolph will be needed tonight as areas of fog and low clouds remain across portions of the state.

Conditions will remain damp and chilly into Christmas as most of the day remains in the 30s.  Our air flow will shift to the south Christmas afternoon and provide a late day boost on the thermometer into the 40s after dark and near 50 by midnight.  As we see the southerly wind erode the chilly conditions in place we’ll also have to be on the look out for a passing shower Christmas afternoon.

Better shower coverage will push in ahead of the cold front Monday morning.  An embedded clap of thunder is also possible.  Winds will shift to the NW with the passage of the cold front Monday afternoon and cooler air will spill into central IN Monday night. That high you see in the upper 50s will come just prior to the frontal passage.

After the mild start Monday, seasonable temperatures will return next week.  Models are struggling with handling a piece of energy the middle of next week.  We’ll keep an eye on it over the next day or so.  Scattered snow showers will likely accompany a push of colder air Thursday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting
  • Rainfall: 0.50″-0.75″
