AREA FORECAST DISCUSSION

.SYNOPSIS...
High pressure maintains control over the area through much of
the week, yielding a stretch of dry weather amid a subtle
warming trend.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 210 AM Tuesday...
Some areas of valley fog are starting to form under clear skies
this morning; however, light flow should result in less
coverage of fog than the past couple of mornings. Whatever fog
does form will quickly dissipate between 8 and 10 AM.
After a cool morning, temperatures are expected to warm into the
70s to low 80s in the lowlands and 60s to mid 70s along the
mountains. Meanwhile, the current stretch of quiet weather
continues uninterrupted throughout the day under the influence
of high pressure. Despite a lack of precipitation, and relative
humidity values once again descending into the 20s to 30s this
afternoon, fire weather concerns should remain relatively low.
For tonight, expect cool, dry, and mostly clear conditions with
low temperatures projected to fall into the 40s to low 50s.
Although coverage should again be fairly limited, patchy valley
fog remains a possibility late tonight into early Wednesday.

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
As of 210 AM Tuesday...
During the middle of the week, an upper trough slowly moves
overhead while high pressure and dry air at the surface
continue to promote benign weather, in addition to a subtle
warming trend. Fire weather concerns may start to increase later
in the week as relative humidity values continue to fall into
the 20s to 30s each afternoon amid a prolonged period without
precipitation.
High temperatures are expected to warm into the mid 70s to 80s in
the lowlands and mid 60s to 70s along the mountains while nightly
lows range from mid 40s to mid 50s.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 210 AM Tuesday...
Upper toughing recedes to the east as an upper ridge builds in
from the west late week into the weekend. The arrival of this
ridge is anticipated to sustain the ongoing dry and uneventful
weather pattern at least through the weekend. Beyond that,
forecast confidence starts to lessen as some models sustain dry
conditions while others bring a system towards the area early in
the new work week.
&&
.AVIATION /10Z TUESDAY THROUGH SATURDAY/...
As of 610 AM Tuesday...
Sub-VFR restrictions will lift as valley fog dissipates by 14Z,
then high pressure will support VFR conditions area wide for
the rest of the day. Patchy valley fog may again produce a
period of IFR/LIFR at a few terminals after 06Z tonight.
Confidence in fog is greatest for EKN, though CRW and PKB could
also be impacted late in the TAF period.
East to southeast winds will be light today, then become calm to
light overnight.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z WEDNESDAY...
