Now We’re Talking…

Screen Shot 2015-03-07 at 10.30.32 AMSpring Fever Anyone?!  A weak weather system is racing through the region this morning.  Clouds and gusty southwest winds are accompanying this, but the air mass is too dry to sustain any sort of precipitation (with the exception of a snow flurry across northern portions of the state).  Sunshine should increase as we progress from morning into the afternoon hours.  Although we’ll remain colder than average this weekend, highs in the lower 40s will feel downright balmy when compared to the bitterly cold times we’ve gone through over the past several weeks.

Early next week will feature a wet weather maker move northeast out of the Deep South, but this should remain east of our region.  We note the European model tries to deliver some light rain Tuesday, but for now we’ll keep our forecast rain-free and dry.

A real surge of “spring fever” will push in here by the middle of the week with highs in the middle 50s Wednesday and upper 50s Thursday (some areas will touch 60 Thursday).  White Leg Warnings will have to be issued, no doubt ;-).

Unfortunately, weather conditions will take a dramatic turn downhill late week into the weekend as a big storm system lifts north out of the Gulf of Mexico.  Colder and raw times are ahead, including a gusty wind-driven rain.  Moderate to heavy rainfall totals appear to be a good bet from 6-7 days out.

Where We Are And Where We’re Going…

It’s another frigid start to the day and this seems to be the story of the winter of 2024-2015. The weather roundup of 7am temperatures and March 6th snow cover…

Light At The End Of The Tunnel…

Screen Shot 2015-03-05 at 7.35.09 AMHang In There; Help Is On The Way…Today and Friday will be incredibly cold for this time of year.  Morning clouds should give way to increasing afternoon sunshine today.  The combination of clear skies, a widespread snowpack, and arctic high pressure overhead will lead to a frigid night tonight.  We officially forecast 2 degrees below zero at IND by Friday morning, but there will be colder reports in outlying areas away from the city.

A moderating trend begins this weekend with sunshine.  A weak weather system will scoot through here Saturday night and early Sunday with a possible light shower or snow shower- not a big deal by any means.

The moderating trend gets even stronger early next week and we forecast highs near 50 Tuesday and pushing 60 Wednesday!  Enjoy!

Warm Up Coming…

After a long and cold winter, many are excited about hearing of the prospects of a warm up and first true taste of spring.

While the European data has totally bought in to the impressive “spring fling” next week, the GFS isn’t as excited of the potentially warmer times.  Case in point, the GFS and European couldn’t be in more different camps for mid and late next week.  Where the GFS has low/ mid 40s for highs the European has low/ mid 60s for highs.  What’s 20 degrees amongst friends?!

Wild model swings and disagreements are common when pattern changes are taking place.   While we might not get as warm as the Euro. would imply, it’s a safe bet we’ll be considerably warmer than the chilly GFS readings.

Note the AO and NAO strongly positive through the next 10-15 days.  This is the time of the year when these teleconnections can impact our region’s weather in the most significant way.  Both of these are warm signals taken at face value.

Note the pattern flip to a “flat” ridge by Day 10, indicative of the milder times ahead.

However, by Day 15 we notice the Alaskan ridge redeveloping.  This is NOT a signal for warm weather across our part of the region, as the steering currents would tap available cold air and direct it south into the Mid West and Ohio Valley.

So, what do we take from this?  We’re going to warm next week without question.  While the extent of the warming is up for debate, the overall milder times for a 5-7 period is a good call at this point.  On the flip side, we’re not ready to buy into the idea that spring is here for good just yet.  The building Alaskan ridge by the end of Week 2 would imply a cold close to March, and potentially continuing into early April.

Another item to keep a close eye on the upcoming 4-6 weeks?  Those NAO and AO signals.  Should they remain predominately positive this time of year then it’ll be exceptionally challenging to get any sort of cold pattern to lock in for more than a day or two.

Watching For Afternoon Snow…

Screen Shot 2015-03-04 at 7.56.01 AMLight Snow Moves In This Afternoon…While heavy snow will remain to our south, we do forecast light snow to overspread portions of central Indiana later this afternoon into the evening hours. This won’t be a huge deal, but a dusting to 1″ of accumulation will be possible around the city, itself.  Heavier snow will fall downstate.  Heads up if you’re traveling south.

The bigger story will be a MUCH colder air mass that arrives tonight and sets up a frigid Thursday.  We’ll be on record watch Thursday to potentially set a new record cold max.  It’ll be close.  Cold air remains with us to wrap up the work week.

A weak weather system will scoot north of the area Saturday night into Sunday morning, but may be close enough to provide a quick rain or snow shower.

Early next week looks dry with a moderating trend.  We’re expecting a more pronounced warm up for the second half of next week…60s, anyone?!

Upcoming 7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 0.10″
  • 7-Day Snowfall Forecast: Dusting to 1″
