Heading In The Wrong Direction…

Screen Shot 2015-04-20 at 3.32.01 PMHighlights:

  • Prolonged unseasonably cool weather
  • Band of showers late Tuesday night/ early Wednesday
  • Frost potential late week
  • Watching a storm system Friday night/ Saturday

SAT_ERG2_VIS_ANISurface low pressure is wrapping up over the Great Lakes region this afternoon with a much cooler air mass flowing into IN.  Though the steady widespread rains have ended, we will maintain a mention of spotty showers into the evening before diminishing.  It’s a gusty day and that will continue.  Most of Tuesday will be rain-free and cool, but a reinforcing push of chilly air will blow into the region late tomorrow night and Wednesday morning, and this will likely be accompanied by a band of showers.  Unseasonably cool air will be the rule through the forecast period.  The next potential “trouble maker” on the radar will take aim on the region late Friday into Saturday.  Forecast models don’t agree on the northward extent of the steady rains, but based off experience and the time of the year we’ll lean towards the solutions favoring a more northerly track.  Stay tuned.

1Forecast radar shown above, courtesy of Weatherbell.com, highlights Tuesday night/ early Wednesday for the threat of a band of showers in advance of a reinforcing push of cool air.

2The next item on the agenda features the potential of wet, chilly, and just downright raw times closing the week and heading into the weekend.  The Canadian model, shown above, is one of a couple models with a more northward flavor of rain Friday night into Saturday.

3Chilly times are the rule for the foreseeable future, friends.  After a warm April (to date), a combination of the GFS and European computer guidance suggests highs are below 60 for the upcoming 10 days.

Winter Storm Tonight-Saturday

Good morning and happy Friday, friends!  Boy, Old Man Winter is really beginning to turn some minds around from thinking this was an easy winter to one that’s quite impressive, especially from a cold standpoint.  By the way, there’s MUCH more from where this came from!  Essentially we remain on “lock down” for more brutally cold and wintry conditions for the upcoming 7-10 day period.  More on that later.

Here’s a look at our initial snowfall forecast map for tonight and Saturday:
