.DISCUSSION...

KEY MESSAGES:

- Mild temperatures are expected through the week.

- Light precipitation chances return on Wednesday.

WEATHER PATTERN OVERVIEW:
A split flow pattern is developing over the region with upper
ridge over the Canadian prairies and upper low moving out of the
central Rockies. This will result in mild temperatures today, and
generally dry conditions although a few sprinkles could occur with
proximity of low moving into the central Plains.

Split flow become more prominent with low digging into southern
California, and mostly zonal flow from the Pacific Northwest into
the northern plains. A weak shortwave sliding along the Canadian
border could produce light precipitation, mainly rain, on
Wednesday. High pressure then dominates the region into the
weekend.

FORECAST CONFIDENCE & DEVIATIONS:
Generally no changes from NBM. Did adjust visibility this morning
to add the potential for patchy fog.

&&

.AVIATION...
VFR, slight chance IFR/LIFR. Mid to high clouds are moving across
the region, inhibiting or clearing out fog and low clouds. A
little fog could redevelop in the river valleys around sunrise,
but widespread or prolonged drop in flight conditions are not
anticipated.

EQUIPMENT: KOLF`s ASOS telecom circuit is down and can not be
dialed into. Therefore, AMD NOT SKED for this TAF until repairs
can be made.
