A deep upper trough will meander over the western U.S. through early
next week while an upper ridge encompasses the eastern U.S. By the
middle of the week, the western upper trough will begin to eject
eastward across the upper Midwest and Great Lakes. In the wake of
the upper trough, an amplified ridge will once again build across
...Day 4-6/Sun-Tue - California...
As the upper trough slowly pushes eastward across the Intermountain
West, surface high pressure will build over the Great Basin. This
will result in several days of deep north to northeasterly flow
across CA, and light offshore/downslope winds are expected. High
temperatures will climb into the 80s to near 90 degrees each
afternoon and RH values will fall into the 10-20 percent range in
lower elevations. At this time, the forecast surface pressure
gradient across the region is modest, and surface wind speeds are
not expected to reach critical criteria. However, where fuels are
dry, elevated fire weather conditions will be a concern given warm
temperatures, low RH and occasionally gusty winds.
