Taking A Moment To Level Set…

Two snow events are lined up to impact at least parts of central IN over the next few days. Friday Light Snow:  We still expect an area of light snow…

Very Cold; Eyes On Sunday-Monday…

Screen Shot 2016-02-10 at 7.10.06 AMHighlights:

  • Scattered snow showers continue
  • Reinforcing arctic air arrives Friday-Saturday
  • Winter storm brewing for some Sunday-Monday
  • Moderating temperatures next week

Very Cold; Eyes On Sunday-Monday…We’ve been dealing with snow showers for over 48 hours.  As expected, accumulations haven’t been uniform, but range, on average, from 1″ to 3″ across central IN.  Morning snow showers continue before drier air will invade from the west and shut the snow production off this afternoon.

Tomorrow will be a dry, cold day before arctic reinforcements arrive Friday into Saturday. Snow showers will accompany the arctic express to close the work week.

Saturday looks brutal. Very cold and windy with below zero wind chills most of the day.

Focus continues on Sunday and Monday and we forecast snow to overspread the area late Sunday night, continuing into Monday.  It’s still early, but this may be a “more important” event, locally.  This will actually come on the “tail end” of the arctic air mass that will have engulfed the region over a week by that point.  We think next week is much milder before we reload the cold to close February and head into March.

Busy, Cold Winter Pattern…

Screen Shot 2016-02-08 at 6.45.51 PMHighlights:

  • Embedded Tuesday squalls!
  • Fast moving NW flow!
  • Bigger winter threat to close the week and again late weekend?

Busy, Cold Winter Pattern…The short term will continue to be dominated by a slow moving upper low over the region. Individual “spokes” (disturbances) of energy will rotate around the upper low and provide enhanced snow showers and embedded heavier squalls through Tuesday night.  As promised, there will be “haves” and “have nots” with this system and, in general, we still like the idea of most folks in the 1″-3″ range with a few isolated heavier totals.

This is a challenging northwest flow and can wreck havoc on the timing front.  Our best idea right now takes a disturbance southeast Wednesday, but this should remain a touch too far west to prevent much more than our southwest tier counties from seeing much, if any, snow.

A stronger clipper may deliver accumulating snow to wrap up the work week and then we also have our late weekend winter event to fine tune.  Get the idea we’re locked into a busy time of things? 🙂

10-Day AG-Weather Outlook…

10 Day AG-Weather Outlook

Issued: 02.07.16

Forecast period: 02.07.16 – 02.17.16

Focal Items:

  • Busy winter pattern from the Plains east
  • Dry and warm across the West
  • Potential widespread winter storm threat days 7-10 from the Plains into the East

Summary: Changes are underway at the beginning of the period with a positive PNA pattern in place.  This will support a drier and warmer than normal time of things across the west with a shift towards much colder than normal temperatures across the eastern half of the country.  Early in the period, we’re tracking a coastal storm that will deliver blizzard conditions to the Cape Monday and a big upper low over the Great Lakes and Ohio Valley.  This will provide a prolonged snow shower event across the areas mentioned above.  Toward the end of the period, we’ll have to remain focused over the southern/ central Plains for the potential of a developing winter storm that would then advance into the Ohio Valley and eventually Mid Atlantic.

Sensible Impacts: Strong ridging across the West will keep things drier and warmer than normal, with the action across the eastern half of the nation.

In addition to snow, wind, and near blizzard conditions that will impact the Cape to open the work week, blizzard conditions will also impact the northern Plains as an upper trough drops south.  The same trough and associated upper level energy will deliver snow showers and embedded blinding snow squalls south into the Ohio Valley and southern Appalachians through mid week, as well.

A very active northwest flow will send light to moderate snow makers southeast out of the N. Plains into the Ohio Valley through the upcoming work week.  Overall, most snowfall accumulations will remain light, with the exception of Snow Belt areas.

A significant winter storm appears to be brewing next weekend and could impact a large portion of the Plains, Ohio Valley, and Mid Atlantic towards the end of the period.

Temperature Anomalies: A very cold time of things is ahead for the forecast region through the period.  In some cases, temperatures will fall to levels some 15-20 degrees below normal.

Precipitation: Snowfall will generally be light through the forecast region this week. Despite the light snowfall, very strong winds will likely lead to blizzard conditions in the open country, particularly across IA and MN early in the period. Heavier snow will be possible as the potential winter storm develops next weekend across the central Plains.
