.DISCUSSION...
KEY MESSAGES:
1) Warm temperatures and dry weather are largely expected over the
next few days, at least through Tuesday.
2) Smoke from Western U.S. wildfires may begin to make its way
over the region with hazy conditions and possible reductions to
visibility at times starting on Sunday.
3) As the ridge breaks down, chances for precipitation begin by
Tuesday night into the second half of the week.
WEATHER PATTERN OVERVIEW:
Upper level ridging will remain a dominant force over the region
for the next several days with warm and dry weather. By Monday and
Tuesday high temperatures will likely push mid to upper 80s for
most of the area. Will also have to watch for wildfire smoke
entering the picture starting on Sunday.
The next cold front will approach for the midweek with the chance
for showers increasing Tuesday night or Wednesday.
FORECAST CONFIDENCE & DEVIATIONS:
Ensemble consensus is fairly robust lending to high forecast
confidence for warm and dry weather through Tuesday, though lower
confidence exists on precipitation chances with increasing spread
among ensemble members for the middle of the week. Overall
therefore kept the forecast in line with NBM for this cycle.
