500 AM CDT Sun Oct 21 2018

.SHORT TERM.../Sunday through Monday/
Beautiful fall morning with plenty of dew around with the wet soil
peculating into the air despite some decent wind speeds for the
predawn hours. There are a few sheltered calm spots in OK/AR with 
the coldest readings in the middle 40s and quite foggy conditions 
such as DeQueen. The I-20 corridor and Southward are still in the
low to mid 50s. Dew points are running a 3 to 5 degree spread in 
the wind and that usually limits dew formation.

High pressure fresh out of Canada is edging into MO with 1030mb. 
The winds will continue to bring in cold air with some gusts 
possible. Our VAD wind profiler is running 35KT at 1kft and 45KT 
at 2kft. So this will keep a chill in the air this morning. Highs 
today will be well below average for late Oct. with low to mid 
60s. These will occur late in the afternoon once the air mass is 
closer in and sprawls out a bit over the mid-South and OH valley.

This will make for a much colder night tomorrow as the pressure 
gradient drops off areawide to near calm for daybreak Monday with
a solid 1024mb contour wrapping the cwa. We are looking 10-15 
degrees colder to start the day with patchy frost along with the 
dew, mainly in the lower elevations along the Hwy 82 corridor 
with mid 30s expected, elsewhere we will be around 41 degrees. 
Highs should be mid to upper 60s as the warming trend begins with 
the departing air mass. /24/



.LONG TERM.../Monday night through Sunday/ 

Western edge of broad surface high pressure begins to move east of 
MS river Monday night allowing for gradual warming trend following 
coolest temps of the fall season thus far. Moisture building along 
se TX coast in active southern stream jet, but trends are for precip 
to remain mostly south of area thru early Wednesday as low pressure 
along coast slower to develop. Low lvl winds will remain ne due to 
proximity of cwa relative to low along coast.  Southwest flow aloft 
to maintain mostly cloudy skies with increased overrunning and 
isentropic lift. Likely pops in near saturated airmass for at least 
portions of area south of I-20 but may be raised areawide if models 
continue to show saturated air across most of area. 

As this coastal low moves east of area, nw flow aloft to bring dry 
air back into region. Deep upper trough swinging just east of area 
in this nw flow will only contain marginal moisture but steep lapse 
rates with elevated instability. Have added isold tstms ne half of 
cwa on Saturday with passage of trough, followed by additional cool 
and dry air to close out remainder of the wknd. /07/

HISTORIC WEATHER EVENTS
...1934...
A severe windstorm lashed the northern Pacific coast. In Washington State,
the storm claimed the lives of 22 persons, and caused 1.7 million dollars
damage, mostly to timber. Winds, gusting to 87 mph at North Head WA,
produced waves twenty feet high. (David Ludlum)
...1957...
The second in a series of unusual October storms hit southern California
causing widespread thunderstorms. Santa Maria was drenched with 1.13 inches
of rain in two hours. Hail drifted to 18 inches in East Los Angeles.
Waterspouts were sighted off Point Mugu and Oceanside. (20th-21st) (The
Weather Channel)
...1987...
Cold arctic air continued to invade the central U.S. Eleven record lows
were reported in the Great Plains Region, including lows of 12 degrees at
Valentine NE, and 9 degrees at Aberdeen SD. Temperatures warmed rapidly
during the day in the Southern and Central Plains Region. Goodland KS
warmed from a morning low of 24 degrees to an afternoon high of 75 degrees.
(The National Weather Summary)
...1988...
Joan, the last hurricane of the season, neared the coast of Nicaragua
packing 125 mph winds. Joan claimed more than 200 lives as she moved over
