"Saving Lives through Education"
High pressure will remain over the Inland Northwest today while moisture feeds up from the south and moves west of our forecast area.
The initial impacts of this moisture will be felt primarily over the Cascades and Central Basin leaving us dry for
now. As such, expect another day with unseasonably hot temperatures. Periods of higher clouds are possible
at times later today & Wednesday as the high pressure ridge slowly weakens and pushes east.
High pressure will temporarily break down just enough to allow some moisture to slowly invade the Inland Northwest. At
this time, the heavier showers look to remain west of our area, but some of that moisture will head our way later Weds
and Thursday. Precipitation amounts remain very uncertain as the main storm driving the moisture moves south into
northern California. Even so, the potential exists for some localized heavy showers should the main moisture feed survive
the trip into Eastern Washington and North Idaho. At the very least, expect more in the way of cloud cover and cooler temperatures, along
with an increased chance of hit & miss showers & thunderstorms later Weds into Thursday. High
pressure is then expected to rebuild by the weekend putting us right back into an unseasonably warm and dry pattern.
