COLDEST START TO SPRING IN 48 YEARS

While the season changed a very cold weather pattern will not let up.  Cold air flowing into central Indiana will likely push overnight temperatures to the lowest readings in a month.  The official high of 33° today in Indianapolis was 21 degrees below normal but also the coldest open to Spring here in 48 years.

BLOCKING PATTERN HOLDS: DAY 33

Since February 15th a pattern change developed in the northern hemisphere.  Known and the “Greenland Block” this feature has played a prominent role in our winter weather for several years.  It was absent last Winter and we went on to have one of the warmest, least snowiest Winters ever.  We also had an amazingly warm March (warmest ever) and Spring that eventually lead to the dry and extremely hot Summer.  Well its is back and in a big way.

Blocking pattern keeps cold over eastern U.S.

Long Range forecasts have handled this feature well and continue to show the relentless pattern will last for at least the next 2.5 weeks.  Average high temperatures are likley to remain a stunning 15 to 20 degrees below normal.  it is possible we may not reach 50° or higher until the second week of April!

WEEKEND STORM POTENTIAL

With the storm track so far south it is not surprising that snow could fall.  The pattern looks more like December and January and if trends continue we could be adding an accumulating snow to the mix.  Current forecast projections are having better agreement on the track and location of a low pressure system as well as the amount of moisture.  Currently we are in a favored position for snow but these trends will be monitored over the next few days.  The storm looks to impact the second half of the weekend.  More in the days ahead.  Be sure to check back or join me nightly on Fox 59.
