From Winter to Spring and Back Again

Meteorologist Melissa Frey’s Weather Discussion:

When the heat was turned on yesterday, there was no stopping it!  The high temperature in Eugene was 67 degrees!  That’s 12 degrees above average! The last time we hit 67 was 126 days ago on November 2nd.

It was also impressive that we got that warm after starting out at just 27 degrees, just one degree higher than the record low.

The ridge of high pressure that allowed for the warm sunny weather is now sliding east.  This opened the door to a weak cold front that will come in tonight.

We’ll see rain showers Friday night which will continue off an on Saturday.  This first storm isn’t all that impressive, but will set the stage for a long series of winter weather.

The next storm after this one moves in Saturday night/Sunday morning.  We’ll see rain, breezy conditions and cooler air ahead of this well developed cold front.  Also overhead, a long wave deep trough will pull down another round of arctic air, which will drop freezing levels to at least 2,000 feet Sunday and down to 1,500 feet Monday.

It doesn’t end there.  Cold air and soggy conditions will stick with us through Thursday.  A second cold front will move through Monday night and a third Wednesday.  The upper level flow at 500mb will rebound slightly Tuesday and Wednesday which will raise freezing levels, but only to about 4,000 feet. This means the passes will see good chances for snow Saturday night through Thursday.

Is looks like our La Nina winter is pulling though…but later than expected.

Have a great weekend,
