Warmest February on Record: Final Numbers

February 29, 2016

5pm Monday…

February was not only the warmest on record here in Portland, but also warmer than a typical March!  Today’s low of 45 and high of 52 are the final numbers of the month, so now we can calculate the numbers:

A full 5.5 degrees above average!  This JUST BARELY beats February last year for the top spot…by all of .1 degree.

These past two Februarys have been a far cry from the cool and wet February 2014 (with the snow & ice) haven’t they?

March is sure looking wet, at least the first two weeks.  Check out the GFS meteogram…the ECMWF is similar:

KPDX_2016022918_tx_240

Temperatures should be near normal, but then it turns cooler about a week from now as a cold upper-level trough edges closer.  You can also see the shift to cooler on the ECMWF monthly maps from last night.

Week 1 & Week 2 (these next two work weeks)

 

Then in week 3 & 4 the trough weakens and retreats farther west along with the ridging over us and north.  This would imply spring starts the 2nd half of the month:

For the real geeks, here are the precipitation anomaly maps for the 4 week period showing much drier weather after the 2nd week…we’ll see.
