NOAA monthly climate briefing held Thursday provided a recap of April and
outlooks through August that indicate a potential warmer and drier summer for
Columbia Basin states.
the rest of the country experienced a warmer-than-average April, and 388
consecutive months of above-global average temperatures and robust
precipitation, the Pacific Northwest has been mired in cold, wet and snow,
often well outside averages since last fall.
upside of the nationwide weather as well as in the Northwest has been an
abatement of drought conditions, to a point where only 5.6 percent of the
contiguous United States has some degree of drought designation. No
designations are active in the Northwest.
El Nino Southern Oscillation forecast, which is based on ocean temperatures,
calls for El Nino or “ENSO neutral” conditions as opposed to the La Nina climate
influence that prevailed during the cold and wet conditions that have dominated
observations come into play for the June one-month outlook, which calls for
normal-to above normal temperatures, but above-normal precipitation is projected
for eastern Idaho and western Montana.
forecast for June, July and August predicts temperatures that are normal or
above normal in the Columbia Basin and normal precipitation, with a trough of
wetter-than-average weather shifting and covering much of the Midwest.
