What forecasters said that day

The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Spokane, WA wrote its last area forecast discussion before this heat advisory went out at May 30, 9:41 PM PDT, 4 hours 37 minutes earlier.

Area forecast discussion, May 30, 9:41 PM PDT, 4 hours 37 minutes before
Area Forecast Discussion
National Weather Service Spokane WA
941 PM PDT Sun May 30 2021

.SYNOPSIS...
It will be a warm and dry Memorial Day under mostly clear skies
and light winds. Temperatures will climb into the 90s through
Thursday, with Wednesday looking to be the hottest day of the
week. A cold front will bring some cooling and potential for
breezy winds around Thursday. A cooler and wetter pattern is
expected for the end of the week into the weekend.

&&

.DISCUSSION...
Tonight through Tuesday night: Are you ready for summer-like
temperatures? Confidence is high that a strong upper-level ridge
will strengthen over the Northwest this week delivering very warm
temperatures and dry conditions. How anomalous is this ridge? If
500mb heights reach 586 decameters or higher on Tuesday, it would
tie/break the record for June 1. So how warm will it be? To give
some reference, temperatures this afternoon have warmed into the
70s and lower 80s. For Monday and Tuesday, tack on another 5-6
degrees each day and we should see widespread valley temperatures
into the 90s by Tuesday afternoon. Overnight lows will also become
increasingly warmer eliminating any concern for freezing
temperatures in our sheltered northern valleys. Temperatures
should still cool enough to kick on the natural air conditioning
that we are accustomed to as overnight lows continue to dip into
the 40s and 50s. Winds will be light and terrain driven with
speeds generally 10 mph or less. /sb

Wednesday through Saturday: Models are in good agreement that
Wednesday will be the warmest day this year, with record breaking
temperatures expected. Temperatures across the Inland Northwest
will be in the mid 90s to low 100s which is about 20 to 25
degrees above average for early June. There will be a moderate to
high risk for heat related impacts on Wednesday, especially for
those sensitive to the heat and those without effective relief
sources from the heat.

By Wednesday night into Thursday, the ridge begins to shift east
and the pattern looks to stay active through the weekend. First, a
weak front looks to push into PNW overnight Wednesday. This will
bring slightly cooler temperatures, breezy winds, and a chance for
thunderstorms. Temperatures will still be quite hot on Thursday
with widespread highs in the 90 expected, but will cool a few
degrees each day. Confidence in the potential for thunderstorms
is quite low at the moment as the front and elevated instability
suggest thunderstorms, but high values of CIN may limit any
development. If thunderstorms were to develop, the greatest
chances look to be limited to the will be for the Blues, L-C
Valley, and the Camas Prairie.

The active pattern continues as another trough moves over the
region sometime late this week into the early weekend. Model
ensembles keep the Pacific Northwest under the influence of a
cool trough through the weekend. This will allow temperatures to
cool back into the upper 60s and 70s. Winds will also be breezy to
gusty through the weekend with gusts over 30 mph possible Friday
and Saturday across the east slopes of the Cascades, the Columbia
Basin into the Palouse and the Spokane area. This doesn't
currently look to be a widespread precipitation event with the
greatest chances for precipitation confined to the Cascades and
the Idaho Panhandle Friday and Saturday. vmt
