.SYNOPSIS...Record breaking heat is already underway as the
strong ridge overhead intensifies over the next few days.
Temperatures will peak tomorrow and Monday before meaningful
onshore flow acts to cool down the region on Tuesday. Temperatures
will not likely cool back down to normal for this time of year and
will remain above average through next week.

.SHORT TERM /TONIGHT THROUGH TUESDAY/...Record breaking
temperatures have been recorded across western Washington this
afternoon, yet it is still early on in the heat event. With Sea-
Tac recording 99 degrees, it becomes the hottest June day on
record, but the next two days look to once again break those
records and then likely breaking into all time record territory.
Relief from the hot temperatures are certainly not likely
overnight in terms of the overnight lows over the next two days
either, as record high low temperatures in the 70s are expected.
Coastal locations are also going to be hot, but likely peaking on
Sunday as the thermal trough along the coast is going to go
through the area on Monday and help initiate some cooling onshore
flow. Monday will likely be the hottest day for the interior as
that thermal trough sets up more over the I-5 corridor. It is
quite unbelievable to have 108-110 in the forecast for Monday in
and around SeaTac, but that is a testament to the strength of this
ridge. Furthermore, it is exceedingly difficult to forecast the
nuances for an event such as this one for which there is no good
analog or comparison for in recent climatological recollection.
The excessive heat warning remains in effect for western
Washington. Those without access to proper cooling and hydration
will remain most at risk for heat illness and related
complications through the weekend and into early next week. Check
with local municipalities and county authorities for information
on cooling centers for those without air conditioning. Here are
some additional tips for staying safe in the heat:
-Avoid strenuous activity and limit time outdoors, especially in
the peak heating of the day. Without overnight relief from the
heat, a general time frame to avoid the outdoors is between 9am-
6pm.
-Make sure to stay hydrated and to drink enough water before
feeling thirsty.
-Check on family, friends, neighbors, and those who do not have
access to proper cooling.
