Hot temperatures are expected through Saturday, with highs well into the 90s and triple digit temperatures. Weather should remain dry with local afternoon breezes. Wildfire smoke will continue to impact portions of the Inland Northwest. A more showery pattern is likely by Sunday into Monday with isolated thunderstorms possible along with a cooler start to next week.
. Widespread triple digit temperatures Friday and Saturday .
Today through Saturday: A return of hot temperatures will infiltrate the region today through Saturday. The ridge is building farther north into Alberta and centering over the Inland Northwest and the Northern Rockies. Daytime temperatures today are already in the 90s and some upper 90s as of early this afternoon. Very dry conditions across the region will continue for much of Friday and part of Saturday. Paired with the hot temperatures and very dry humidities, unstable conditions will be present which could pose elevated or critical fire weather conditions especially near our wildfires. While winds will not be of much concern, even some elevated breezy winds may increase this threat.
Overnight the temperatures will struggle to bring cooling relief to much of the region, especially low-land and valley areas tonight, Friday night, and again Saturday night. We've upgraded the Heat Advisory to an Excessive Heat Warning. Temperatures should soar to at least 10 degrees above seasonal normals.
. Hot and dry conditions through early Saturday could spell elevated fire weather concerns for fire development or spread .
Saturday's temperatures could be in jeopardy of not reaching our forecast values due to incoming clouds and moisture. A shortwave feature will move north through the Great Basin early Saturday which will be accompanied by our moisture plume. Impressive precipitable water values are advertised and have been consistent with each model run. Values of 1 to 1.5" and even hints at slightly higher have been showing up consistently from south- central Idaho through northeast Washington and into north-central Washington on the eastern slopes of the Cascades. Instability will be on the rise as forecast soundings have shown better elevated CAPE but not ideal as the available instability will likely remain in the warm sector. Can't rule out chances for lightning, especially in Idaho and parts of southeast Washington, but coverage looks pretty isolated. Convection looks better Sunday into Monday (more on that below). /Dewey
Saturday PM through Wednesday: Isolated convection possible Saturday afternoon and evening before becoming more widespread Sunday morning, and chances continue through Sunday and Monday. After more warm morning temperatures, high temperatures cool slightly Sunday and the next couple of days as the upper level trough noses in from the northwest. Recent model runs have backed off from suggesting precipitation Tuesday as the monsoonal moisture exits the region.
Higher RH and winds that aren't too breezy won't be too supportive for rapid fire growth despite decent chances of lightning Sunday and Monday. However, outflow from storm cells could cause locally gusty winds. Good news is these higher RHs mean more rain will reach the ground before evaporating. We're even looking at flash flood potential; current thinking is that southeast flow will bring more development to the North Cascades on Sunday. RC
AVIATION . 00Z TAFS: Winds will remain mostly light under nearly clear skies through the next 24 hours. Some haze from nearby wildfires may worsen visibility at area air fields, especially those in northern Washington and northern Idaho. /Dewey
