...18Z AVIATION UPDATE...

.SHORT TERM...(Today and tonight)

Cold Canadian air was fully anchored over extreme southeast Kansas
and the Missouri Ozarks this morning. Temperatures responded by
falling into the low to middle 20s, under clear skies and north
breezes.

This dry continental airmass will remain in place for several
days, ultimately shutting down any chances for precipitation.
Unfortunately with limited precip chances, drought conditions are
expected to become worse over southern Missouri.

For today look for highs to only make it into the low to mid 30s.
North breezes will persist.

Tonight will be the coldest night of the winter season, with lows
falling into the low to middle teens.

.LONG TERM...(Friday through Wednesday)

As we progress through the weekend, the area will remain under the
inflection of a trough to the east, and a ridge to the west. This
northwest flow will keep moisture at bay, with a continuous
pipeline of dry air into the nation`s midsection.

Temperatures for the most part will be seasonal through the
weekend with highs in the 40s and 50s, with lows below freezing
each night.

Not much will change next work week. A shortwave trough will pass
through Monday bringing another shot of Canadian air to the
region.  The airmass will be too dry for any precipitation.

The models suggest that the positive PNA pattern will persist
through the next seven to ten days.
