I. Temperature and precipitation overview

Meteorological winter (dec-Jan-feb) 2014-2015 was characterized by a
semi-permanent West Coast upper level ridge which lead to average
temperatures being 3 to 6 degrees above normal across the entire
region. Precipitation totals varied from slightly above normal in
the Grande Ronde Valley and Blue Mountain foothills to slightly
below normal elsewhere. Snowfall for the three month period was well
below normal for all climate sites surveyed in this report, with
Yakima, WA recording its least snowy meteorological winter on
record. The highest snow totals for the three month period were
recorded at Redmond and La Grande, or where just over 5 inches
fell. The average temperature ranked in the top twelve warmest for
the period of record at all sites, with Yakima, WA and Redmond, or
reporting their second warmest winter on record.

Due to the storm track being deviated well away from the Pacific
northwest for a majority of the month of January, and the dry weather
that the multiple ridges brought to the area, a few record lowest 10
rainfall totals were set throughout the region. The following table
lists the location, the rank, the January rainfall total, and the
record lowest January rainfall total or the previous record in cases
where the 2015 temperature was the new record.

In addition to the lackluster precipitation totals throughout the
region, the unseasonably warm conditions also contributed to the

january:

Iii. Significant weather

December:

A cold front and a powerful low pressure system brought widespread
strong winds to much of the region on December 10th and 11th. The
cold front, which was associated with a deep low pressure system off
the northern British Columbia coast, helped to increase the pressure
gradient across the area leading to an increasing south wind during
the day on December 10th. A robust upper level jet aided in the
rapid development of a new area of low pressure off the Oregon coast
by the morning of December 11th. This powerful low pressure system
paralleled the Oregon coast through the day on the 11th and, in
combination with downsloping mountain winds, created damaging winds
in several locations. The hardest hit areas were the Blue Mountains,
Wallowa Mountains and the southern Cascades of Oregon. The following
table lists selected peak wind gusts from each County affected
across the area:

Location time and date peak wind gusts in mph
1 WNW Cayuse, or 10:45 am on the 11th 95
1 NW Heppner, or 01:11 PM on the 11th 88

Pendleton Airport 02:00 PM on the 11th 59
13 WSW Mikkalo, or 01:20 am on the 11th 59

Other than the strong damaging winds, the storm system also brought
rather low surface pressures and several periods of rain to much of the
area. The observed minimum pressure readings and four day
precipitation totals from December 9th through the 12th were as follows:

Location pressure reading precipitation amount
Redmond, or 989.2mb 0.12 inches
dalles, or 989.7mb 0.19 inches
Walla, Walla, WA 990.1mb 1.07 inches
Pendleton, or 990.9mb 0.71 inches
Yakima, WA 991.9mb 0.23 inches
Pasco, WA 992.4mb 0.15 inches

Meacham, or also reported 1.50 inches of precipitation during this
four day period, with 2.4 inches of snow on December 12th as snow
levels lowered across the region.

Toward the end of the month on December 28th and 29th an Arctic cold
front with an associated upper level disturbance moved through the
area. This system brought limited moisture into the region, but was
able to combine with a northerly upslope flow to produce localized
areas of moderate to heavy snowfall. The accumulating snowfall mainly
occurred along the foothills of the Blue Mountains, along the Blue
Mountains, along the east slopes of the Washington and Oregon Cascades,
as well as in central Oregon. Little, if any, snow fell in the lower
elevations of the Columbia Basin or in the Columbia River gorge. The
following table lists selected snowfall amounts from each County
affected across the area:

10se Cliffdell, WA 0108 am on the 29th 5.0 inches


January:

On January 15th a stronger weather system moved into the Pacific
northwest and combined with marginally cold air banked up against the
Washington Cascades to produce snow. The snow developed and fell
starting during the midday hours on January 15th in the Yakima Valley,
Kittitas Valley and East Slope of the Washington Cascades. The snow
finally tapered off and ended during the predawn hours of January 16th,
but not before 1 to 4 inches fell in the Yakima and Kittitas Valley
regions. This system pro
