.DISCUSSION...
KEY MESSAGES:
- Windy day Friday in wake of a cold front.
- Warming trend begins soon after with warmest days Sunday and
  Monday. Then cooling starting Tuesday.
- Models are slowly starting to increase agreement on
  precipitation by next week.
WEATHER PATTERN OVERVIEW:
Omega block over the western states has allowed for near record
warmth again across the area today. But a cold front will drop
southeast through the area Friday morning with strong NW winds in
it`s wake. Speeds look to be about 15 to 25 with gusts to 35 mph
over Fort Pack Lake, so have issued a Lake Wind Advisory, from 6
am till 6 pm.
Upper low remains in place over southern California with ridge
rebounding across the plains into the weekend. Early next week an
Alaska low begins to dig a trough off the west coast, with the
California low weakening and lifting through the southwest flow
aloft. With the lack of the blocking feature and the western
trough moving onshore, moisture could increase enough for
precipitation by the end of the forecast period.
A cooling trend can be expected starting Tuesday as more clouds
enter the picture.
FORECAST CONFIDENCE & DEVIATIONS:
Increased winds with a mix of the NBM and NBM 90 for Day 2.
Followed NBM for the remainder of the forecast. TFJ
