.DISCUSSION...

KEY MESSAGES:

- Scattered light showers taper off today, then periodic and
  limited shower/thunderstorm chances return starting on Sunday.

- There is high confidence for slightly warmer than normal
  conditions this weekend into much of next week.

WEATHER PATTERN OVERVIEW:

The remaining periphery of a low pressure system continues to
provide just enough forcing, along with daytime heating today,
for scattered sprinkles and light showers to move through until
late afternoon. Little or no accumulation will result. A warm up
will occur this weekend as a positively tilted ridge builds into
the area. Although there is high (70 percent) confidence of dry
weather occurring through early next week, ensembles are hinting
at isolated showers and thunderstorms occurring from Sunday into
early next week from shortwave disturbances and daytime
instability. However, upper level moisture will be limited with
the pattern presenting no heavy rainfall concerns at this time.

CONFIDENCE AND POTENTIAL DEVIATIONS FROM BASE FORECAST:

High confidence exists on a warming trend this weekend, as
deterministic forecast highs in the 70s and lower 80s continue to
be on the lower end of the ensemble ranges. There is low
confidence on the timing of precipitation probabilities with any
measurable amounts late this weekend into next week.
