.PREV DISCUSSION... /Issued 217 PM CST Thu Dec 7 2017/

DISCUSSION...
A weak upper level disturbance will push southward through the
Panhandles overnight. This disturbance should move through with
little fanfare. However, there is some warm air and moisture
advection in the dendritic growth zone, mainly over the northwest
CWA. This moisture and warm air advection should result in clouds
which could produce some light snow. At this point, it looks like
the snow will evaporate before hitting the ground as the low levels
remain dry. For now have gone ahead and mentioned flurries in our
northwest CWA closest to the warm air advection, moisture advection
and upper level dynamics.

The surface pressure gradient will be tight on Friday which will
result in strong northwest winds. Winds will likely be in the 20 to
30 mph range with higher gusts, but could be a little higher in
the northwest CWA. Relative humidity values will also drop to near
20 percent across much of the area, so elevated fire weather
conditions will be possible.

The upper level ridge/trough pattern across the U.S. will persist
through this forecast which will keep the region dry. High
temperatures will continue to warm through the weekend and then
another cold front should knock highs back a little for early next
week.
