  for shower activity across the Sierra and Great Basin.

.DISCUSSION...through early next week.

Shortwave which sparked a few showers across the southern Great
Basin today is moving east early this morning en route towards the
Four Corners. Broad troughing remains across the West through it`s
fairly weak and slight height rises today will allow for gradual
warming trend to continue. On Thursday, a weak shortwave will
drift across the Baja but generally remain south of the US Border
and have fairly limited impact on our region besides some high
clouds. Then one weaker shortwave will drop into Northern Arizona
from Utah and mostly just stir up the north winds down the
Colorado River all the while a slow warming trend continues. By
the weekend, stronger ridging will finally build into the Four
Corners region allowing for temperatures to peak several degrees
above normal Saturday and Sunday.

By early next week, a deeper trough will drop south along the
California coast and slowly move inland. There remains uncertainty
on its depth and exact track, but a cooling trend and a return of
shower chances, especially across the Sierra and southern Great
Basin is expected.

through the forecast period will remain light, around 6KT, and
follow typical daily directional patterns with some variability,
particularly in the morning and early evening. VFR conditions will
prevail, with passing bands of mid- level and high clouds with
bases at or above 10kft.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Lingering showers
across the southern Great Basin will dissipate early in the
forecast period, with dry conditions thereafter. Winds across the
region will follow typical daily directional patterns the next 24
hours, with speeds around 5-10KT. The exception to this will be
across the western Mojave Desert/KDAG, where winds maintain a
westerly component through the period, with sustained speeds
around 10-12KT and intermittent gusts to around 20KT tonight and
again late Wednesday evening. VFR conditions with passing bands of
