.KEY MESSAGES...
1. Below average temperatures and dry conditions are expected 
for the next several days.

2. A disturbance moving south from near Alaska and a low 
pressure system tracking south of us and coming off the Pacific 
Ocean could potentially bring the next chance for precipitation 
in our area by this coming weekend (low confidence).

.DISCUSSION...
Central California experienced mostly sunny skies and near-
seasonal temperatures today. A disturbance moving through the 
Pacific Northwest brought cooler conditions and stronger winds 
over the higher terrain of the Sierra Nevada and the Coastal 
Range, though it remained too far north to bring precipitation. 
Temperature-wise, the Probability of Exceedance (PoE) of 
reaching 70 degrees remains above 70 percent through Friday, 
dropping below 20 percent over the weekend. The PoE of reaching 
75 degrees outside the Mojave Desert remains below 10 percent 
into early next week. Lingering moisture may produce mist and 
haze across the San Joaquin Valley-primarily between Visalia and
Hanford-ahead of the next storm system. Fog remains unlikely, 
with the PoE of visibility dropping below 3 miles sitting at 
less than 10 percent.

Long Term  Ensemble models continue to show strong consensus 
for a robust storm developing off the Pacific Northwest coast on
Saturday, bringing another round of precipitation to Central 
California starting late Saturday into early Sunday morning. The
heaviest precipitation is expected later in the day on Sunday. 
While confidence in precipitation is high, model variability 
remains regarding exact accumulation totals due to a split flow 
weather pattern. Current guidance indicates:

* 48-Hour Probability of Precipitation (Late Saturday  Early
  Monday): 25-45% chance of receiving 0.50 of an inch across 
  the Sierra Nevada.
* 48-Hour Snow Probabilities (Late Saturday  Early Monday):
  20-40% chance of receiving 4 inches across the Sierra Nevada
  above 7,000 feet. 
* 50th Percentile: Precipitation is very likely across the
  region this weekend.
* 90th Percentile: (Worst-Cast Scenario): Up to 2 inches of
  liquid equivalent (rain/snow) across Central California.

We will continue to monitor and evaluate the potential for heavy
(excessive rainfall) rainfall as new guidance become available.
