Another quiet night across the mid state, with the threat of fog
again in the forecast this morning. Satellite trends showing some
fog development, but not as much as last night at this time. Have
fog mention in the forecast and will continue to monitor for any
additional development overnight.

With upper ridging building in today, temps will warm a bit to
yield highs in the upper 50s for most of the area. Dry conditions
will continue for most of the day Friday, but an approaching
Plains trough will have cloud cover move in from west to east
during the day, and increase wind speeds at the surface. Still
looking like southerly winds will be around 10 to 15 mph with 
gusts around 25 mph by the early afternoon Friday, and may pick up
to be 15 to 20 mph with gusts to 30 mph in the late afternoon and
evening especially at higher elevations. Chances for rain will
move in from the west by mid afternoon and spread across the area
overnight, with the best chances during the evening Friday through
early morning hours Saturday.

The upper trough should move through quickly, and skies will begin
to clear from west to east Saturday. Still may be some lingering
showers on the Plateau late morning Saturday but the sun should be
out for most of the mid state by mid afternoon. With shortwave
ridging moving in between troughs, temps will be quite warm with
most of the area seeing the low 60s. Dry weather will be short
lived as a stronger trough will move in Sunday. Models are still
not lining up all that well yet, but at least they all agree on a
more northerly track which has the upper closed low around central
IL by 00Z Monday. This has the best chances for the next round of
showers Sunday afternoon through the overnight hours Monday
morning. Still looks like by the time its cold enough for snow or
mixed precip, the moisture is off to the east, so still holding on
to all rain in the forecast for now.

With another trough/closed low over the Great Lakes region next
week, northwest flow will settle in aloft for most of the week.
Models are having a hard time lining up with shortwaves moving
through the area and timing on any cloud cover/brief shower
chances, so kept next week mostly dry in the forecast. With
northwest flow aloft, there wont be much rebounding of temps, so
highs in the 40s and lows in the upper 20s/low 30s can be
expected. Models diverge even more by late next week, with just
about a completely opposite solution for Thursday and Friday
between the GFS and ECMWF. The Canadian has a somewhat similar yet
more aggressive solution compared to the GFS, so went ahead and
added in slight chance/chance pops for Thursday afternoon through
Friday morning.

Historical Weather And Climate Facts For Today

An observer at Boston MA recorded a "great tempest of wind and rain from
the southeast all night, as fierce as a hurricane, and thereupon followed
the highest tide which we have seen since our arrival here". (David Ludlum)
Extremely destructive Santa Ana winds blew from Oxnard to San Diego and
inland parts of southern California. The high winds produced a 28,000 acre
brush fire on a 40-mile front west of Crystal Lake. People were ordered off
streets in some areas due to flying debris. (21st-22nd) (The Weather
Over two inches of rainfall was received at the Jackson, KY Weather Office and 
the London, KY Corbin Airport in 1991. London measured 2.18 inches of 
rain...while Jackson picked up 2.99 inches of precipitation. Both amounts 
established new daily rainfall records for November 22nd.
