Oct 2010 Intermountain West Climate Summary
Summary
Temperature — Nearly all locations across the Intermountain West region had above-average temperatures for September, as there were few storms to bring cold air or much moisture.
Precipitation — September was a very dry month for the region, with a large swath across all three states seeing less than 0.25\" of precipitation.
ENSO — A strong La Niña event has developed, and is expected to persist at least through spring 2011, influencing the climate outlook for our region throughout this period.
Climate Outlooks — For November and subsequent seasons, the CPC seasonal outlooks call for an enhanced probability of warmer-than-average temperatures and an enhanced probability
of below-average precipitation for the southern portions of the Intermountain West, consistent with typical La Niña conditions.
