Stormy Evening…

Screen Shot 2016-02-02 at 7.24.07 AMHighlights:

  • Strong to severe storms this evening
  • Rain and snow showers Wednesday
  • Dry and chilly to wrap up the work week
  • Nice weekend ahead
  • MUCH colder next week

Stormy Evening…Tuesday is dawning nice and quiet with dry and chilly conditions in place.  A bit of fog has been reported just west and north of the city.  The quiet times will give way to a bumpy ride by this evening as a warm front passes, allowing a strong SW breeze to boost temperatures close to 60 (after dark high).

Scattered showers will develop this afternoon, but it’s the evening hours that we bracket (between 4-10p west to east) for the potential of strong to severe storms.  Some of these storms will be capable of damaging winds, and even a quick spin-up tornado can’t be ruled out.  Have a way to get the latest weather information this evening.

We turn cooler Wednesday with lingering moisture falling in the form of mixed rain and snow showers.  This won’t be a big deal.

Dry times will be with us to end the week and rumble into the Super Bowl weekend, with moderating temperatures.  The moderating trend won’t last long as models continue to suggest an arctic blast looms next week.  To go along with that cold, snow chances will also come.

Morning Ensemble Disco.

*Part of what we send our clients is a daily (two times/ day during active periods) ensemble discussion.  Here’s an excerpt of this morning’s discussion that went out earlier.  By the way, if you’re interested in joining our weather consulting services, please e-mail bill@indywx.com for more details.

…We note some significant differences in our morning ensemble data that’s creating some doubt in terms of the longevity of the coming cold.  We still feel the heart of the cold is in the Mid West and Ohio Valley with this early February surge.  The EC is likely a battle zone, at least initially.

EuroFeb5th

GEFSFeb5thThe European is much more progressive in breaking down the cold across the central and east, while the GFS ensembles look much more realistic to us.  Why?  The GoA trough placement.  The EPS is likely “dragging its heels” across the southwest with the southern energy and in return deepens the trough too much across the four corners region.

We see the GEFS going to a significant cold period in the 10-14 day period, centered over the mid section into the Ohio Valley.  This is also during the time frame we think the first of two winter events impacts the Ohio Valley.

gfs-ens_T2ma5d_us_10We’ll issue an afternoon ensemble discussion after having an opportunity to digest 12z data.  Look for it in your inbox by 6p.
