.DISCUSSION...
Tonight through Tuesday: High pressure will move into southern
British Columbia and our temperatures will continue to warm. High
temps will be in the 60s, with low 70s for for portions of the
Highway 97 corridor, Moses Lake/southern Columbia Basin region
and the LC Valley. Lows will be in the 30s to low 40s. After
tonight/Saturday morning low temperatures being near average,
temperatures will be 6 to 15 degrees above average for the middle
of March. Skies will be mostly clear to clear, and winds will be
light.
Wednesday through Friday: The ridge begins to get pushed east
Tuesday night and Wednesday with the next weather system moving
towards the Pacific Northwest. Clouds will begin to increase
Wednesday and we bring in a 20 to 30% chance of rain to the region
with up to a 50% chance of precipitation to the ID mountains. The
Columbia Basin and Wenatchee area currently looks to be shadowed
out and will remain dry. Temperatures begin to cool Wednesday,
but the big decrease in temps comes Thursday as the region returns
to near average readings...upper 40s and 50s for the valleys and
30s to low 40s for the mountains. Breezy southwest to west winds
will increase Wednesday. Showers and cooler temperatures will
continue through the remainder of the week. /Nisbet
