.AVIATION...
VFR will prevail with generally clear skies through the period.
Very light southerly winds now will become light westerly in a few
hours as a surface trough moves across. After sunrise, deep mixing
will help transport stronger northwest winds down to the surface.
Expect speeds of 10-15kt to prevail. These winds will diminish
rapidly after sunset as decoupling occurs and become light
westerly. TR.92

.SHORT TERM... /Issued 311 PM CST Fri Dec 8 2017/
An upper level trough will exit the state this evening and allow a
reinforcement of dry and cold air to filter in from the northwest.
Temperatures tonight will be cold again with all locations
reaching freezing or below. However, it will be a bit warmer
than last night due to some high cloud cover and warmer
temperatures this afternoon. Overnight lows will range from the
middle twenties to the lower 30s.

.LONG TERM... /Issued 311 PM CST Fri Dec 8 2017/
A high amplitude ridge will stay anchored on the West Coast
through early next week while a broad longwave trough resides
across the eastern half of the nation. This pattern will keep the
Lone Star State in dry northwest flow aloft with only some passing
high clouds.

The shallow, cold airmass that`s currently in place will steadily
modify through early next week due to abundant sun and daytime
mixing. As a result, a warming trend will ensue with highs mainly
in the 50s Saturday, 60s Sunday and lower 70s Monday. Since the
air will remain very dry with light winds and a mostly clear sky,
it will still be cold each night with lows generally in the 30s.

A fast moving shortwave embedded in northwest flow will move out
of Canada and across the Plains Monday night through Tuesday which
will send another cold front southward across North and Central
Texas. The front will not have any moisture to work with and will
come through without any precipitation. The front will knock
temperatures closer to seasonal normals with highs around 60 and
lows in the upper 30s.

A gradual warmup will take place the second half of next week as a
the West Coast ridge deamplifies and translates eastward. It will
remain dry Wednesday through Friday, so overnight lows will still
be on the chilly side and generally in the 30s.

The long range models continue to show some low rain chances
returning about 8 to 10 days out due to a southern branch upper
trough moving in from the Pacific. We will be keeping an eye on
this system in the coming days.
