.METEOROLOGICAL CONDITIONS (WED AM - TUE AM)...

An upper trough is currently moving through the PacNW and nrn CA/NV
with an upper ridge offshore over the eastern Pacific. As the trough
continues its inland progression there will be a slight chance of
isolated showers/thunderstorms over eastern NV this
afternoon/evening. The offshore ridge will then begin to move in
behind the exiting trough into Thursday keeping conditions dry and
kicking off a warming trend. Ridging will remain overhead throughout
the rest of the week bringing afternoon high temps about 5 to 15 deg
F above normal away from the immediate coast. Another trough is then
on tap to move through the PacNW over the weekend bringing temps
back down closer to normal to 10 deg F above normal for interior CA
and parts of NV. Coastal areas are looking at below normal temps for
the weekend.

To start the coming week, models show a stronger upper low dropping
in from the Gulf of ALaska sending a front through the PacNW. The
southern edge of the system is expected to pass through srn OR and
nrn CA on Monday generating some precip along the north coast and
over the srn OR Cascades. Highest amounts are forecast at about 0.25-
0.50" over the Smith Basin and the crest of the Cascades with a few
hundredths to 0.10" elsewhere. The rest of the region to remain dry
through the period. Heights to rise across the region starting
Tuesday warming temperatures 10-20 deg F above normal for mid-week
away from the coast.
