1051 PM EDT FRI SEP 23 2016
A weak cold front slides into the area on Saturday. A much stronger
cold front will arrive late Monday or Monday night.
.NEAR TERM /THROUGH SATURDAY/...
As of 1050 PM Friday...
No significant changes made...tweaked temps based on current obs
As of 100 PM Friday...
A weak cold front will move southward into the area late tonight and
Saturday. Moisture and dynamics are limited with the front...so
showers only possible during the daytime heating hours on Saturday.
Will continue to go above MOS guidance south of the cold front on
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 1225 PM Friday...
A weak cold front will sag and stall over the southern portion of
the area and become non-existent. Mostly clouds will be
associated with it. Only difference will be the cooler air behind
it will filter in for the weekend. The next cold front is expected
to move into the area by late in the afternoon on Monday and
continue to cross the area Monday night. Moisture is lacking and
should only see convection with the front as it passes. Temps will
be noticeably cooler throughout.
.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 12:25 pm Friday...
Cold front exits by Tuesday afternoon taking any precip with it.
Much cooler and drier air works its way in behind it as high
pressure builds across the region by Tuesday night. A secondary
trof axis rotates across the northern portion of the CWA Tuesday
night and Wednesday. Best chances of any precip will be north of
the CWA and we should only see clouds with this. Cool high
pressure will start to build across the region Wednesday night and
for the rest of the week. Cooler and more fall like temperatures
are expected as well.
.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
As of 720 PM Friday...
A weak cold front will approach from the north tonight. This
should keep some mid and high clouds in place and limit fog
formation for most. Did include some IFR fog at EKN. Fog should
not linger much past 12Z. Cannot rule out an isolated shower
Saturday, mainly across the northern mountains, but probabilities
too low to include in EKN TAF right now. Could also get brief MVFR
ceilings across the northern TAF sites as the front sinks
through...but forecast soundings generally indicate better chance
of a broken layer is above 3kft.
