AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1003 PM PDT Thu Aug 28 2014

.Synopsis...
Dry weather to continue for the next week. Warm temperatures to
continue today, with a gradual cooling trend expected through next week.

&&

.Discussion...

Upper high is firmly in place over California. This is providing
dry and warm conditions. Only a weak delta breeze this evening
with temperatures slower to cool. Current forecast is on track and
no evening update will be needed.

.Previous Discussion...
High pressure is bringing sunny skies, generally light winds and
above normal temperatures. Today continues to be on track to be the
warmest day we will see for the next week or so. Temperatures are
currently warmer across the forecast area by 2 to 8 degrees and highs
this afternoon should reflect these trends. The northern
Sacramento Valley should see some triple digits, with Chico 99
degrees at 3 pm, 98 at Redding and at Red Bluff.

A very weak wave passes through this evening, with a more
substantial but rather dry trough passing through to the north
tomorrow and Saturday. This will bring cooler temperatures for the
end of the week. A stronger Delta breeze is also expected tonight
into early Friday.

Dry weather is expected into next week. Ex-hurricane Marie
continues to weaken and move out into the Pacific. The only
affects for the forecast area should be some increased clouds on
Friday, drawn in by easterly flow as the upper trough tracks
through the region.

Dry northwest flow continues through the Labor day weekend. High
temperatures will be near to a little above normal. EK

.Extended Discussion (Monday through Thursday)

Dry northwesterly flow aloft over Interior NorCal into early
Tuesday as deep short wave system progresses across the middle
part of the U.S. and upper ridging persists in the EPAC.
Temperatures are expected to be near normal. Models then show
another significant pacific short wave approaching Tuesday,
tracking across the PacNW Wednesday into Thursday. This will
bring lowering heights over NorCal as troughing aloft deepens,
resulting in some cooling with increased onshore flow midweek.
