.SHORT TERM...(THIS EVENING THROUGH Tuesday NIGHT)
ISSUED AT 132 PM CST MON NOV 20 2017

IR satellite and obs show only thin cirrus over the area and time
height cross sections show that continuing for the next 24-48
hours. A dry cold front will push through late Tuesday afternoon
into the evening. Moisture is scant and generally Pacific in
origin. No return flow from the Gulf seen for the next several
days. Temperatures on Wednesday will be 10-15 degrees lower than
Tuesday.

.LONG TERM...(Wednesday THROUGH Monday)
ISSUED AT 132 PM CST MON NOV 20 2017

Models are in remarkable agreement through the forecast period.
Very little pattern change until next week. A ridge over the west
shifts little over the next several days. The trough over the
eastern portion of the U.S. remains in place as well and is
reinforced from systems out of Canada from time to time.

At the start of the period, the trough associated with the late
Tuesday cold front is already over the northeast U.S. The next
system, which on Wednesday is over northwest Canada, will continue
to slide southeast and bring reinforcing colder air with another
dry cold front passage on Saturday. So after recovering to the
upper 50s to lower 60s on Saturday, highs will drop to the lower
40s to lower 50s across the area on Sunday.

Overall a decent travel weekend is in store for the mid-south.
